Adventures & experiences in contemporary technology
When you set up your own web server or use a private server (virtual or physical), you will find that web servers run using the www-data account. That means that website files need to be accessible to that system account if not owned by it. The latter is mandatory if you you want WordPress to be able to update itself with needing FTP details.
It also means that you probably need scheduled jobs to be executed using the privileges possess by the www-data account. For instance, I use WP-CLI to automate spam removal and updates to plugins, themes and WordPress itself. Spam removal can be done without the www-data account but the updates need file access and cannot be completed without this. Therefore, I got interested in setting up cron jobs to run under that account and the following command helps to address this:
sudo -u www-data crontab -e
For that to work, your own account needs to be listed in /etc/sudoers or be assigned to the sudo group in /etc/group. If it is either of those, then entering your own password will open the cron file for www-data and it can be edited as for any other account. Closing and saving the session will update cron with the new job details.
In fact, the same approach can be taken for a variety of commands where files only can be access using www-data. This includes copying, pasting and deleting files as well as executing WP-CLI commands. The latter issues a striking message if you run a command using the root account, a pervasive temptation given what it allows. Any alternative to the latter has to be better from a security standpoint.
There are times when I just need to share some links outside the fleeting environment of Twitter, and this is where they might appear. The practice is very much in the spirit of the original weblog idea when it was about link sharing and not about writing down one’s thoughts as it subsequently became before sharing of photos, videos and other multimedia content became a mainstay of (legal) sharing for some people.

If you ever need to install Linux kernel headers on an openSUSE instance in order to install VirtualBox Guest Additions, the following command should be executed in order to do the needful:
sudo zypper in kernel-source

Here is a possible way of resetting the CSS definition for a HTML element, class or ID:
#reset-this-parent {
all: initial;
* {
all: unset;
}
}
Browser support for the above may vary though.

After seeing messages like “The authenticity of host ‘hostname’ can’t be established” during ssh connections, I decided to investigate more and came up with the following solution:
sudo chown -v $USER ~/.ssh/known_hosts
My known_hosts file had gained root ownership so i could not write to it so changing the ownership to that of my own user account sorted the problem. An alternative could be to change the group assignment using chgrp and setting permissions using chmod but what I did sufficed for my needs.

When I ran into trouble with accessing my own websites using my broadband, I found that the solution was to change DNS Lookup Service to what Google offers. This was done on the router side and the IP addresses used were 8.8.8.8 and 8.8.8.4.

Here is a way to recursively delete folders and their contents in PowerShell:
Remove-Item .\foldertodelete -Force -Recurse
The Force switch silences any messages that otherwise would appear and the Recurse switch is what gets directories removed.

Devuan (pronounced like dev-one) is a fork of Debian that does not use systemd as Debian, like so many other distros, is doing. Part of the name must come from a collective calling itself Veteran UNIX Admin (VUA). There is no actual release just but one is intended for around the same time as Debian 8.0 gets released and donations are being solicted via the website.

When a VirtualBox upgrade broke the networking on a Windows 8.1, it was time to look at System Restore to see what it would do. It reverted version 4.3.20 to 4.3.15 and the network disconnection stopped. For now, I will remain with that older version after the misstep with the latest one. Sometimes it is best to stick with what is known to work.

With my deciding to try doing about my waistline during the summer (a bike got put on a trainer and around 30 minutes is spent on it most evenings while I also catch up some reading; now, I feel fitter and incursions into the countryside have an added air of confidence about them), an interest in fitness monitors has developed and the Pulse Ox from Withings has taken my eye due its being price of around £100. That makes it less than alternatives and it isn’t the only health gadget that the company does either with there being a blood pressure monitor in its range too. The Pulse Ox monitors such things as heart rate, activity such as walking and running, sleeping and weight too. It should work with your smartphone as well, which is a bonus. It is one of several like it with Samsung and Apple going in for phone apps and Microsoft releasing their Band device as well. This appears to be a growing area where I never expected to see mainstream technology companies having a role for themselves.

Here is the test for the “Shellshock” vulnerability in the bash shell:
env x='() { :;}; echo vulnerable’ bash -c “echo this is a test”
It should not return the following:
vulnerable
this is a test
This would be acceptable:
bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x’
this is a test
Also, just having this might be fine too:
this is a test
In case you need it, Redhat has more information on the bug that caused scare stories everywhere. Now, it is over to system administrators everywhere to do their bit now that bash has been patched.
21:36 August 24, 2014
Sometimes you need to create more than one directory level in a hierarchy at once and mkdir has the -p option for this purpose. That gets it to create any missing levels in a folder path and avoids warnings that would be issued otherwise.

Debian 8 is under development and has its first beta ready for download. XFCE is now the default desktop environment though it remains possible to install GNOME and GNOME Shell too. In fact, I successfully have given that a go in a VirtualBox installation and will keeping an eye on development so long as no system meltdowns occur. The version of the X Window system already is incompatible with VirtualBox 4.3.14 so we need to await a new version of the virtualisation software before we get access to advanced functions like full window desktop expansion. What we have at the moment works well enough to keep eye on development so we can wait for that full support.

Perfect Resize from onOne Software caught my eye for scaling up images after seeing it mentioned in a Outdoor Photography review of Avanquest PhotoZoom Professional. With a library of 6″ x 4″ prints, I am limited in how large I can make scanned images without they looking blurred and pixelated so that’s why my interest was aroused. There may be a free moment spent seeing what it might do in that situation yet.

Nvidia has a useful page on the difference between DVI-D and DVI-I. It came in handy when transitioning from VGA to DVI on my home PC’s. That made what appears on my Iiyama screen much sharper and allowed me to rid myself of a suspect VGA cable too.

Here are some interesting articles about EFI and UEFI that I uncovered during a recent episode of setting up dual booting of Windows 8.1 and Linux Mint 17 on a PC with EFI:

In the U.K., BT allows you to divert your phone calls for a fee and I have made good use of it over the past year. The service is called Call Diversion and Eircom, Ireland’s counterpart to BT, offers Call Forwarding in Éire. Both are handy because redirecting a call to a mobile phone means that you know you are not missing any calls and that there is nothing lurking on an answering machine when you do get to your home or office. Landline telephony may seem less exciting these days than other forms of communication yet it still has its place and I would not get any nasty surprises along the path of life either. If only I had started doing this kind of thing earlier than I did…

Here’s a useful article about the ever useful locate command. Whether it is FreeBSD or Ubuntu that you are running, this article has a use and that especially when the locate database needs updating with the updatedb command.

A recent website redesign was well helped by modern.IE‘s collection of virtual machine appliances containing different versions of Windows and Internet Explorer. Depending on the host operating system that you are using, you have different options. For Linux, it is VirtualBox only while Windows gains VMware and Virtual PC too. It is a matter of just picking out what suits your situation from dropdown lists.
The first one that I picked was Vista with IE 7 and it was an interface that I had not seen for a while. For all the criticism, the operating system did work well though I wonder if it arrived before the computer hardware that it really needed in order to run smoothly. The dark theme cannot have helped its cause either, especially when compared with the much brighter Windows 7 or Windows 8.x. A Windows XP appliance with IE 6 was grabbed before it gets yanked and support for the elderly OS does finish in April. IE 6 probably is on its last legs so I probably can ignore it now but IE 7 might live longer yet. Window 7 appliances with IE 9 and IE 10 also were downloaded and confirmed that all was well in recent versions of IE when it came to the website. The Vista virtual machine allowed me to ensure that all looks acceptable on IE 7 too. The VM’s themselves contain evaluation versions of enterprise variants of Windows and have a limited lifespan though it is little trouble to reimport an appliance again to rest the clock if so required. In most cases, you extend the evaluation periods too through re-arming and there only are so many times that you can do that anyway. With Windows 8.x, it isn’t even a possibility anyway.
22:05 March 9, 2014
Today, I found an interesting article on CSS media queries and put it to some use for a website redesign that has been keeping me busy over the weekend. Twitter’s Bootstrap came in handy for this too. Now, it’s on to ridding the new design of any rough edges that remain in there. That can be an ongoing task and the site is here if you fancy a look to see what my efforts have produced.
16:20 February 26, 2014
Adding a new Zalman ZM450-GS power supply did little to sort the buzzing in my speakers but it has made the PC where it was installed so much quieter; a much larger fan spinning slower helps while still moving the required amount of air. It is 450W too and I am wondering if my main PC would benefit from a similar upgrade. That may be quieter than the other one was but the case was not a deluxe model so the change should do no harm. As for the speakers, moving them was the only way to get rid of the buzzing. Looking back on this now, it seems that one of them was far too close to a PC.
20:33 February 15, 2014
Currently, the spare PC appears to be causing buzzing on my main PC speakers and with my landline telephone when it is placed right under these. Removing it helps to cut it down but I fancy having a better fix and am wondering if a new power supply might help. Also, I am wondering if there are other sources too. In the meantime, I would like to share an article on the subject that I recently found: Kill Studio Hum and Buzz at the Source.
22:14 February 12, 2014
Applying latest set of updates to LMDE worked to get to Update 8 worked smoothly unlike some predecessors. This brought the latest version of Cinnamon so GNOME now is redundant. It will be interesting to see where things go next.
16:24 February 8, 2014
During the week, I discovered that Twitter is not a benign place to go ruminating. A sharp riposte in an unnecessary tone of voice was enough to bring on a sense of extra caution. Wherever you get humanity, you are likely to encounter and one had a go at me so some thoughts are going to be kept away from there from this point forward. Sometimes, you own website is a far better place to go ponder happenings in the world around you. After all, an ugly comment can be deleted and a rogue IP address blocked if things need to go that far. Of course. more civility would be best. Polite correction is the best course whenever it is warranted since we all are human and no one is beyond making mistakes.
16:15 February 8, 2014
On my outdoors website, I have been using a PHP script from Detect Mobile Browsers but this does not distinguish between Android running on a tablet and that running on a phone. Therefore, I have turned to another source of such scripting and that is working better so far. In fact, this offers more than just PHP but also Python, JavaScript and other scripting languages along with configuration files for web servers too. Apache, Nginx and IIS all have something for them. The logic essentially is based on Perl regular expression matching of user agent strings, not an infallible means but good enough for me along with a smattering of responsive design.

For anyone lost when faced with the changes Microsoft brought in with the launch of Windows 8 and largely retained in Windows 8.1, TechRadar has a useful article: 62 Windows 8 tips, tricks and secrets. What will prove especially interesting is where Microsoft goes next when many of their customers prefer the Windows 7 interface and are sticking with the elderly Windows XP. You only can get so far by telling your customers that they are wrong all of the time and the is competition in the form of Apple’s OS X and Google’s Chrome now.

TechRadar has a round-up of Best free photo editing software: 10 top image editors you should try. Usual options like GIMP, Paint.Net and IrfanView get a mention along with other less well known ones. Interestingly, Google’s Picasa is excluded from the list but that might be because it largely is an image file management tool even if it has some image editing capabilities too.
21:28 January 27, 2014
Late last week, I found out about the image file sorting tool PhotoSift via an article on the software. It looks interesting though I have yet to try it.
17:52 January 27, 2014
Here are some interesting reviews from TechRadar:
Best compact system camera 2014: the top models reviewed
Best tripod and camera support: 13 tested
The tripod heads review really caught my eye more than the others. After all, 2013 was the year that I got a CSC and a Manfrotto tripod has sat reproachingly in the corner far more often than it should.
19:41 January 16, 2014
Today, I spotted two interesting articles to which I want to retain links on here:
Managing the future of complex business and IT landscapes
Send large files to clients with these 8 free tools
Both of these ring bells for me for different reasons. The first is a reminder of a slow and painful system project with which I was involved and of an ineffective IT support service that pained us at the time. The second is ever present in my current job with its need to send data and output files to clients as well as receiving specifications from them.
19:36 January 4, 2014
In recent weeks, I have been having trouble with the onboard network controller on a spare PC that I have at home. It connects to the network fine for a few minutes and then struggles. Making use of an old PCI ethernet card that I had from another machine solved the problem. Does anyone know of issues with ASRock motherboards and onboard network ports at all? It isn’t something that I have seen before and this motherboard never had good networking capability as long as I have had it.

After Christmas, I took delivery of an HTC One mini mobile phone that I got free as part of a contract renewal with O2. It also is known as the M4 and I have been getting used to it since I got it. A lot is familiar and there are some little differences too. Some of these leave me asking why what worked well before got changed to something that is less smooth. Of course, that can be the course of things and it applies to buying a new car as much as getting a phone upgrade. All in all, the phone works well and battery life appears much improved over the HTC Desire S so far, never a bad thing to notice.

This morning, the hosting provider for this website had an outage that lasted over three hours. The provider was Fasthosts and the cause was a power failure. They usually are good so this thankfully does not happen too often. However, we have been getting a lot of stormy weather crossing Britain and Ireland this winter so I suspect that there should be little in the way of surprise when something like this happens. Weather is not due to settle during this month so there may be more power failures, hopefully elsewhere, before things settle down again.

On one WordPress website that I have, the refresh rate for RSS widgets wasn’t the quickest and the remedy was to add this line into the themes functions.php file:
add_filter( ‘wp_feed_cache_transient_lifetime’, create_function(‘$a’, ‘return 600;’) );
It creates a custom function that is attached to the widget and the refresh time is set to 600 seconds or 10 minutes. So far, this seems to be doing what I needed.

What I didn’t realise is that TRIM currently is not enabled in Ubuntu by default. That is set to change in Ubuntu 14.04 and here is some advice on the matter until then.
20:41 December 14, 2013
This weekend, I had visions of needing a new hard drive when all files on one in my main home PC (runs Ubuntu GNOME 13.10 64-bit) went read only. The cure was to re-seat the SATA cables and all was well again. Sometimes, inexpensive remedies are best and I need not to forget this one.
20:54 October 29, 2013
Here are two interesting articles that I spotted: the first is on new features in GNOME 3.10 and the second about getting DRM-protected Flash media playing on Ubuntu 13.10. For now, I am sticking with Ubuntu GNOME 13.04 in spite of a pop-up dialogue encouraging an upgrade to 13.10; the potential for even a little disruption is something that I am delaying for now.
20:34 October 16, 2013
While editing a file in Nano on an virtual Arch Linux web server that I have, I noticed that a file had DOS newline characters instead of UNIX ones so conversion using the dos2unix command was in order. There is more on this to be found on nixCraft and there are other options such as sed described in there too.
21:51 September 7, 2013
Following a look at Webmin, I have to say that it seems a worthy tool for remote management of servers. My trial so far has been on my Ubuntu virtual web server and it works on port 10000 without interfering with the operation of the actual web server. Being able to run system updates and deletion of MySQL databases without resorting to the command will seem a bonus for some. There’s more to it than these though and I have seen the possibility of managing virtual servers located within a real being mooted. It was an issue of Linux User & Developer than inspired me so my Linux magazine reading is seeing its uses.
20:30 September 4, 2013
Here are some interesting articles for anyone thinking about software development and its realities:
The care and feeding of software engineers (or, why engineers are grumpy)
Being an introvert as I am, this article really is something to which I can relate. Whenever I cannot get the space for undisturbed work, it takes from how I enjoy my job.
How designers and engineers can play nice (and still run with scissors)
We all have to work cross-functionally so you cannot have it all your own way…
Six reasons why the NHS National Programme for IT failed
Having been involved in system design, development and implementation myself, I have something to share that fits into the same topic area. Too many cooks can spoil a broth.
Queensland Government Bans IBM from IT Contracts
My past experiences of IBM have not been good and it wasn’t just where I worked either so this is not exactly a surprise. Service organisations need to ensure that they are sufficient responsive and flexible with empowered and enthusiastic staff who do the needful.
23:09 August 11, 2013
Vagrant and Puppet look like very interesting tools for working with virtual machines. They work with VirtualBox or VMware’s Fusion and Workstation so there’s a choice of virtualisation tool.

Crash reports have been appearing after logging into an Ubuntu session for /usr/share/hplip/config_usb_printer.py and it repeating has been reinstalling HPLIP software for my HP LaserJet 1018 printer too. Leaving the printer off until I need it would be one solution and saves some electricity too but it is best to try to sort an issue when you keep getting it. The first step was to download the latest HP software and install it. That wasn’t a complete solution so I altered the latest send_message function call in /usr/share/hplip/config_usb_printer.py from the following:
send_message( device_uri, printer_name, EVENT_DIAGNOSE_PRINTQUEUE, username, 0,”)
to:
send_message( device_uri, printer_name, EVENT_DIAGNOSE_PRINTQUEUE, ”, 0,”)
So far that alteration appears to have addressed the problem but I’ll be keeping an eye on things anyway. If you’re wondering, the inspiration came from a bug discussion on Launchpad and it was the queue clearing section of the Python script that I went and edited.
20:40 April 16, 2013
Recently, I have been having bother with WordPress Jetpack comment form submission. This was caused by the Bad Behaviour plugin and allowing cross site form submission sorted the problem. The setting to change is in Settings > Bad Behaviour on the Dashboard.

20:53 February 19, 2013
During a look at a Fedora 18 Live DVD, I found a user name was needed to get to the desktop and root did the trick for me. What I didn’t notice was an install to hard drive option for the GNOME variant that I tried. Maybe it was hidden on the desktop and not displayed. If so, it looks like an oversight.

Here’s a command for removal of orphaned packages in Arch Linux and its derivatives (CinnArch and ArchBang come to mind but there may be others):
sudo pacman -Rns $(pacman -Qqtd)
15:11 January 26, 2013
Cinnarch looks very interesting. It’s based on Arch Linux so it’s a rolling distro but has Cinnamon as its desktop environment. Currently, it’s still in beta but I am tempted to give it a go in a virtual machine.
20:55 December 15, 2012
Having decided that my ever sluggish system needed a fresh operating system installation, I set to trying to get on Linux Mint 14. However, not remembering that the disk and not the partition needs specifying for GRUB installation cost me some time. Later, adding on GNOME Shell resulted in a system conflict between MDM and GDM so I now am running Ubuntu GNOME Remix instead. All feels fresher so far though a spot bother was had with the lock screen that caused me to turn off the feature. VMware Player installed without any of the trickery needed to get in its forbear and runs without a hitch so far too. Other bits and pieces need instating yet but the basis of a refreshed computing platform is in place now.
20:56 November 19, 2012
A look at Linux Mint 14 64-bit release candidate in a VirtualBox virtual machine confronted me with irritating mouse pointer behaviour. The pointer constantly darts to the left when you need it not to do that and it seriously affects usability. The final version will be awaited to see if there is an improvement because it’s not very usable as things stand. GNOME Shell can be installed in working order after a spot of fiddling. Installing the software from the Software Store doesn’t add gnome-session as well so the command line alternative remains best:
sudo apt-get install gnome-shell && sudo apt-get install gnome-session
These two really need packaging together as dependencies. Cinnamon is looking as nice as ever and in need of a plug-in that makes virtual desktops behave as they do in GNOME, even if that’s a minority interest now.
12:07 September 30, 2012
Here are commands for adding Cinnamon to Ubuntu:
sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
sudo apt-get install cinnamon
14:39 September 29, 2012
Had a look at GNOME 3.6 in Ubuntu GNOME Remix 12.10 Beta 1 release. Not all extensions are supported yet but GNOME 3.6 only launched officially yesterday anyway. Will take a little while for those extension developers to catch up with it. No hurry in moving from GNOME 3.4 until they do so.
20:24 September 22, 2012
Picked up Netgear ethernet switcher at PC World today. Working without a hitch so far. Some network reorganisation may follow suit.
20:14 September 22, 2012
Initially, I needed to use the command “modprobe vboxdrv” to get VirtualBox going on Sabayon 10. However, there seems to be a better remedy: adding the line ‘modules=”vboxdrv vboxnetflt vboxnetadp”‘ (removing the outer single quotes, by the way) to /etc/conf.d/modules and restarting the system. That seems to have done the trick though I wonder it wasn’t added for me automatically.
13:08 September 22, 2012
Until recently, I hadn’t realised that most if not all SSD’s come in 2.5″ form factor. An extra bracket is needed for installing into 3.5″ drive bays. While tempting, this remains a nice to have upgrade for me.
20:02 September 21, 2012
Found out why my proftpd daemon wasn’t working on Linux Mint. Needed to set it as standalone and not inetd operation. It’s the ServerType setting in /etc/proftpd/proftpd.conf.
21:53 September 18, 2012
Given the site a new appearance. The cause was getting microblogging going on this page. Clashes with zeeDisplay theme and Twitter Tools made for replacements that now power what you see here. Jetpack plugin added too. All looking good to my eyes so far. More tinkering may happen yet.
21:36 September 15, 2012
Here are a few places where you will find Linux version information stored: /etc/issue, /etc/issue.net, /etc/lsb-release.

Desktop swapping can be done in Ubuntu and here’s the command for Xubuntu:
sudo apt-get install xubuntu-desktop
17:22 September 15, 2012
Here’s a set of commands that I once used to get GNOME Shell going for a Sabayon 9 installation in a VirtualBox virtual machine:
su
equo install --ask linux-sources
cd /run/media/john/VBOXADDITIONS_4.1.16_78094
./VBoxLinuxAdditions.run
mv /usr/libexec/gnome-session-check-accelerated-helper /usr/libexec/gnome-session-check-accelerated-helper.bak
ln -s /bin/true /usr/libexec/gnome-session-check-accelerated-helper
Hope they have a use though VirtualBox has gone through a few versions since I discovered that these had the desired effect though the login screen behaved a little oddly. Otherwise, everything worked as it should.
14:16 September 15, 2012
Pondering purchase of NAS. QNAP TS-412 looking promising but need to think about my home networking set up first. Might need an ethernet switch but plan to look into it more first, especially with uplink capability needed.
14:11 September 15, 2012
Appearance of Sabayon 10 caused a bit of disturbance to my Sabayon installation that needed installation from a DVD to resolve. Tried GRUB repairs before the non-loading of an Nvidia kernel module caused bother. Went for old fashioned approach for sake of saving a little troubleshooting time.
13:52 September 15, 2012
This has been added using the Live Blogging plugin and it’s good for pages too, unlike Automattic’s own Liveblog plugin. Maybe they’ll add that sort of functionality in time.
This year has seen some optimisation being applied to my web presences guided by the results of GTMetrix scans. It was then that I realised how slow things were, so server loads were reduced. Anything that slowed response times, such as WordPress plugins, got removed. Usage of Matomo also was curtailed in favour of Google Analytics while HTML, CSS and JS minification followed. What had yet to happen was a search for a faster server. Now, another website has been moved onto a virtual private server (VPS) to see how that would go.
Speed was not the only consideration since security was a factor too. After all, a VPS is more locked away from other users than a folder on a shared server. There also is the added sense of control, so Let’s Encrypt SSL certificates can be added using the Electronic Frontier Foundation’s Certbot. That avoids the expense of using an SSL certificate provided through my shared hosting provider and a successful transition for my travel website may mean that this one undergoes the same move.
For the VPS, I chose Ubuntu 18.04 as its operating system and it came with the LAMP stack already in place. Have offload development websites, the mix of Apache, MySQL and PHP is more familiar to me than anything using Nginx or Python. It also means that .htaccess
files become more useful than they were on my previous Nginx-based platform. Having full access to the operating system by means of SSH helps too and should mean that I have fewer calls on technical support since I can do more for myself. Any extra tinkering should not affect others either, since this type of setup is well known to me and having an offline counterpart means that anything riskier is tried there beforehand.
Naturally, there were niggles to overcome with the move. The first to fix was to make the MySQL instance accept calls from outside the server so that I could migrate data there from elsewhere and I even got my shared hosting setup to start using the new database to see what performance boost it might give. To make all this happen, I first found the location of the relevant my.cnf
configuration file using the following command:
find / -name my.cnf
Once I had the right file, I commented out the following line that it contained and restarted the database service afterwards using another command to stop the appearance of any error 111 messages:
bind-address 127.0.0.1
service mysql restart
After that, things worked as required and I moved onto another matter: uploading the requisite files. That meant installing an FTP server so I chose proftpd since I knew that well from previous tinkering. Once that was in place, file transfer commenced.
When that was done, I could do some testing to see if I had an active web server that loaded the website. Along the way, I also instated some Apache modules like mod-rewrite using the a2enmod
command, restarting Apache each time I enabled another module.
Then, I discovered that Textpattern needed php-7.2-xml installed, so the following command was executed to do this:
apt install php7.2-xml
Then, the following line was uncommented in the correct php.ini configuration file that I found using the same method as that described already for the my.cnf
configuration and that was followed by yet another Apache restart:

Addressing the above issues yielded enough success for me to change the IP address in my Cloudflare dashboard so it pointed at the VPS and not the shared server. The changeover happened seamlessly without having to await DNS updates as once would have been the case. It had the added advantage of making both WordPress and Textpattern work fully.
With everything working to my satisfaction, I then followed the instructions on Certbot to set up my new Let’s Encrypt SSL certificate. Aside from a tweak to a configuration file and another Apache restart, the process was more automated than I had expected so I was ready to embark on some fine-tuning to embed the new security arrangements. That meant updating .htaccess
files and Textpattern has its own, so the following addition was needed there:
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
This complemented what was already in the main .htaccess
file and WordPress allows you to include http(s) in the address it uses, so that was another task completed. The general .htaccess
only needed the following lines to be added:
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.assortedexplorations.com/$1 [R,L]
What all these achieve is to redirect insecure connections to secure ones for every visitor to the website. After that, internal hyperlinks without https needed updating along with any forms so that a padlock sign could be shown for all pages.
With the main work completed, it was time to sort out a lingering niggle regarding the appearance of an FTP login page every time a WordPress installation or update was requested. The main solution was to make the web server account the owner of the files and directories, but the following line was added to wp-config.php as part of the fix even if it probably is not necessary:
define('FS_METHOD', 'direct');
There also was the non-operation of WP Cron and that was addressed using WP-CLI and a script from Bjorn Johansen. To make double sure of its effectiveness, the following was added to wp-config.php to turn off the usual WP-Cron behaviour:
define('DISABLE_WP_CRON', true);
Intriguingly, WP-CLI offers a long list of possible commands that are worth investigating. A few have been examined but more await attention.
Before those, I still need to get my new VPS to send emails. So far, sendmail has been installed, the hostname changed from localhost and the server restarted. More investigations are needed but what I have not is faster than what was there before, so the effort has been rewarded already.
UNIX (and Linux) does a wonderful trick with its file and folder shortcuts; it effectively treats them as file and folder transporters that transfer associate a file or folder that exists in one folder hierarchy with another and it is treated as if it exists in that hierarchy too. For example, the images folder under /www/htdocs/blog can have a link under /www/htdocs/ that makes it appear that its contents exist in both places without any file duplication. For instance, the pwd command cannot tell a folder from a folder shortcut. To achieve this, I use what are called symbolic links and the following command achieves the outcome in the example:
ln -s /www/htdocs/blog/images /www/htdocs/images
The first file path is the destination for the link while the second one is that for the link itself. I had a problem with Google Reader not showing up images in its feed displays so symbolic links rode to the rescue as they did for resolve a similar conundrum that I was encountering when editing posts in my hillwalking blog.
My experience is with Ubuntu on this one but I have found that you need to be careful as regards the file system used by the drive where you keep your virtual machines. If it is NTFS, VMware can fail to start a VM because it cannot create a virtual memory file while it presents as physical memory to a guest operating system. Use ext2 or ext3 and there should be no problem, even if that means formatting a drive to fulfill the need. That’s what I did and all was well thereafter.
With UNIX being the basis of Linux, I have a soft spot for trying out any UNIX that can be installed on a PC. For a while, I had OpenSolaris on the go and even vaguely recall having a look at one of the BSD’s. However, any recent attempt to install one of the latter, and there are quite a few around now, got stymied by some sort of kernel panic caused by using AMD CPU’s. With the return to the Intel fold arising from the upgrade of my main home PC last year, it perhaps was time to try again.
The recent release of FreeBSD 10.0 was the cue and I downloaded a DVD image for a test installation in a VirtualBox virtual machine with 4 GB of memory and a 32 GB virtual hard drive attached (expanding storage was chosen so not all the allocated space has been taken so far). The variant of FreeBSD chosen was the 64-bit x86 one and I set to installing it in there. Though not as pretty in appearance as those in various Linux distros, the installer was not that user unfriendly to me. Mind you, I have experience of installing Arch Linux so that might have acclimatised me somewhat.
Those installation screens ask about the keyboard mapping that you want and I successfully chose one of the UK options. There was limited opportunity for adding extras though there was a short list of few from which I made some selections. User account set up also was on offer and I would have been better off knowing what groups to assign for my personal user account so as to have to avoid needing to log in as root so often following system start up later. Otherwise, all the default options were sufficient.
When the installation process was complete, it was time to boot into the new system and all that was on offer was a command line log in session. After logging in as root, it was time to press pkg into service in order to get a desktop environment in place. The first step was to install X:
pkg install xorg
Then, it was time to install a desktop environment. While using XFCE or KDE were alternatives, I chose GNOME 2 due to familiarity and more extensive instructions on the corresponding FreeBSD handbook page. Issuing the following command added GNOME and all its helper applications:
pkg install gnome2
So that GNOME starts up at the next reboot, some extra steps are needed. The first of these is to add the following line into /etc/fstab:
proc /proc procfs rw 0 0
Then, two lines were needed in /etc/rc.conf:
gdm_enable=”YES”
gnome_enable=”YES”
The first enables the GNOME display manager and the second activates other GNOME programs that are needed for a desktop session to start. With each of these in place, I got a graphical login screen at the next boot time.
With FreeDSB being a VirtualBox Guest, it was time to consult the relevant FreeBSD manual page. Here, there are sections for a number of virtual machine tools so a search was needed to find the one for VirtualBox. VirtualBox support for FreeBSD is incomplete in that there is no installation media for BSD systems though Linux and Solaris are supported along with Windows. Therefore, it is over to the FreeBSD repositories for the required software:
pkg install virtualbox-ose-additions
Aside from the virtual machine session not capturing and releasing the mouse pointer automatically, that did everything that was needed even if it was the open source edition of the drivers and their proprietary equivalents. To resolve the mouse pointer issue, I needed to temporarily disable the GNOME desktop session in /etc/rc.conf to drop down to a console only session where xorg. conf could be generated using the following commands:
Xorg -configure
cp xorg.conf.new /etc/xorg.conf
In the new xorg.conf file, the mouse section needs to be as follows:
Section “InputDevice”
Identifier “Mouse0”
Driver “vboxmouse”
EndSection
If it doesn’t look like the above and it wasn’t the case for me then it needs changing. Also, any extra lines from the default set up also need removing or the mouse will not function as it should. The ALT+F1 (for accessing GNOME menus) and ALT+F2 (for running commands) keyboard shortcuts then become crucial when your mouse is not working as it should and could avert a panic too; knowing that adjusting a single configuration file will fix a problem when doing so is less accessible is not a good feeling as I discovered to my own cost. The graphics settings were fine by default but here’s what you should have in case it isn’t for you:
Section “Device”
### Available Driver options are:-
### Values: <i>: integer, <f>: float, <bool>: “True”/”False”,
### <string>: “String”, <freq>: “<f> Hz/kHz/MHz”
### [arg]: arg optional
Identifier “Card0”
Driver “vboxvideo”
VendorName “InnoTek Systemberatung GmbH”
BoardName “VirtualBox Graphics Adapter”
BusID “PCI:0:2:0”
EndSection
The next step is to ensure that your HAL settings are as they should. I needed to create a file in /usr/local/etc/hal/fdi/policy called 90-vboxguest.fdi that contains the following:
<?xml version=”1.0″ encoding=”utf-8″?>
<!--

With all that set, it is time to ensure that the custom user account is added to the wheel and operator groups using this command:
pw user mod [user name] -G wheel operator
Executing the above as root means that the custom account can run the su command so that logging in as root at the start of a desktop session no longer is needed. That is what being in the wheel group allows and the anyone in the operator group can shut down or restart the system. Both are facilities readily available in Linux so I fancied having them in FreeBSD too.
Being able to switch to root in a terminal session meant that I could go on to add software like Firefox, Libreoffice, GIMP, EMACS, Geany, Netbeans, Banshee and so on. There may be a line of opinion that FreeBSD is a server operating system but all of these make it more than passable for serving as a desktop one too. There may be no package management GUI as such and the ones that come with GNOME do not work either but anyone familiar with command line working will get around that.
FreeBSD may be conservative but that has its place too and being able to build up a system one item at a time teaches far more than getting everything already sorted in one hit. So far, there is enough documentation to get me going and I hope to see where else things go too. So far, the OS hasn’t been that intimidating and that’s good to see.
So as not to deface anything that is available online on the web, I have a tendency to set up an offline Apache server on a home PC to do any tinkering away from the eyes of the unsuspecting public. Though Ubuntu is my mainstay for home computing, I do have a PC with Fedora installed and I have been trying to get an Apache instance starting automatically on there without success for a few months. While I can start it by running the following command as root, I’d rather not have more manual steps than is necessary.
httpd -k start
The command used by the system when it starts is different and, even when manually run as root, it failed with messages saying that it couldn’t find the directory while the web server files are stored. Here it is:
service httpd start
The default document root location on any Linux distribution that I have seen is /var/www and all is very well with this but it isn’t a safe place to leave things if ever a re-installation is needed. Having needed to wipe /var after having it on a separate disk or partition for the sake of one installation, it doesn’t look so persistent to me. In contrast, you can safeguard /home by having it on another disk or in a dedicated partition and it can be retained even when you change the distro that you’re using. Thus, I have got into the habit of having the root of the web server document root folder in my home area and that is where I have been seeing the problem.
Because of the access message, I tried using chmod and chgrp but to no avail. The remedy has to do with reassigning the security contexts used by SELinux. In Fedora, Apache will not work with the context user_home_t that is usually associated with home directories but needs httpd_sys_content_t instead. To find out what contexts are associated with particular folders, issue the following command:
ls -Z
The final solution was to create a user account whose home directory hosts the root of the web server file system, called www in my case. Then, I executed the following command as root to get things going:
chcon -R -h -t httpd_sys_content_t /home/www
It seems that even the root of the home directory has to have an appropriate security context (/home has home_root_t so that might do the needful too). Without that, nothing will work even if all is well at the next level down. The switches for chcon command translate as follows:
-R : recursive; applies changes to all files and folders within a directory.
-h : changes apply only to symbolic links and not to where they refer in the file system.
-t : alters context type.
It took a while for all of this stuff about SELinux security contexts to percolate through to the point where I was able to solve the problem. A spot of further inspiration was needed too and even guided my search for the information that I needed. It’s well worth trying Linux Home Networking if you need more information. There are references to an earlier release of Fedora but the content still applies to later versions of Fedora right up to the current release if my experience is typical.
There is a bill making its way through the U.K. parliament at the moment that could reduce the power of copyright when it comes to images placed on the web. The current situation is that anyone who creates an image automatically holds the copyright for it. However, the new legislation will remove that if it becomes law as it stands. As it happens, the Royal Photographic Society is doing what it can to avoid any changes to what we have now. There may be the barrier of due diligence but how many of us take steps to mark our own intellectual property? For one, I have been less that attentive to this and now wonder if there is anything more that I should be doing. Others may copyleft their images but I don’t want to find myself unable to share my own photos because another party is claiming rights over them. There’s watermarking them but I also want to add something to the image metadata too.
That got me wondering about adding metadata to any images that I post online that assert my status as the copyright holder. It may not be perfect but any action is better than doing nothing at all. Given that I don’t post photos where EXIF metadata is stripped as part of the uploading process, it should be there to see for anyone who bothers to check and there may not be many who do.
Because I also wanted to batch process images, I looked for a command line tool to do the needful and found ExifTool. Being a Perl library, it is cross-platform so you can use it on Linux, Windows and even OS X. To install it on a Debian or Ubuntu based Linux distro, just use the following command:
sudo apt-get install libimage-exiftool-perl
The form of the command that I found useful for adding the actual copyright information is below:
exiftool -p “-copyright=(c) John …” -ext jpg -overwrite_original
The -p switch preserves the timestamp of the image file while the -overwrite_original one ensures that you don’t end up with unwanted backup files. The copyright message goes within the quotes along with the -copyright option. With a little shell scripting, you can traverse a directory structure and change the metadata for any image files contained in different sub-folders. If you wish to do more than this, there’s always the user documentation to be consulted.
Though my main home PC runs Linux Mint, I do like to have the facility to use Windows software from time to time and virtualisation has allowed me to continue doing that. For a good while, it was a Windows 7 guest within a VirtualBox virtual machine and, before that, one running Windows XP fulfilled the same role. However, it did feel as if things were running slower in VirtualBox than once might have been the case and I jumped ship to VMware Player. It may be proprietary and closed source but it is free of charge and has been doing what was needed. A subsequent recent upgrade of video driver on the host operating system allowed the enabling of a better graphical environment in the Windows 7 guest.
Instability
However, there were issues with stability and I lost the ability to flit from the VM window to the Linux desktop at will with the system freezing on me and needing a reboot. Working in Windows 7 using full screen mode avoided this but it did feel as I was constrained to working in a Windows machine whenever I did so. The graphics performance was imperfect too with screening refreshing being very blocky with some momentary scrambling whenever I opened the Start menu. Others would not have been as patient with that as I was though there was the matter of an expensive Photoshop licence to be guarded too.
In hindsight, a bit of pruning could have helped. An example would have been driver housekeeping in the form of removing VirtualBox Guest Additions because they could have been conflicting with their VMware counterparts. For some reason, those thoughts entered my mind and I was pondering another more expensive option instead.
Considering NAS & Windows/Linux Networking
That would have taken the form of setting aside a PC for running Windows 7 and having a NAS for sharing files between it and my Linux system. In fact, I did get to exploring what a four bay QNAP TS-412 would offer me and realised that you cannot put normal desktop hard drives into devices like that. For a while, it looked as if it would be a matter of getting drives bundled with the device or acquiring enterprise grade disks so as to main the required continuity of operation. The final edition of PC Plus highlighted another one though: the Western Digital Red range. These are part way been desktop and enterprise classifications and have been developed in association with NAS makers too.
Looking at the NAS option certainly became an education but it has exited any sort of wish list that I have. After all, there is the cost of such a setup and it’s enough to get me asking if I really need such a thing. The purchase of a Netgear FS 605 ethernet switch would have helped incorporate it but there has been no trouble sorting alternative uses for it since it bumps up the number of networked devices that I can have, never a bad capability to have. As I was to find, there was a less expensive alternative that became sufficient for my needs.
In-situ Windows 8 Upgrade
Microsoft have been making available evaluation copies of Windows 8 Enterprise that last for 90 days before expiring. One is in my hands has been running faultlessly in a VMware virtual machine for the past few weeks. That made me wonder if upgrading from Windows 7 to Windows 8 help with my main Windows VM problems. Being a curious risk-taking type I decided to answer the question for myself using the £24.99 Windows Pro upgrade offer that Microsoft have been running for those not needing a disk up front; they need to pay £49.99 but you can get one afterwards for an extra £12.99 and £3.49 postage if you wish, a slightly cheaper option. There also was a time cost in that it occupied a lot of a weekend on me but it seems to have done what was needed so it was worth the outlay.
Given the element of risk, Photoshop was deactivated to be on the safe side. That wasn’t the only pre-upgrade action that was needed because the Windows 8 Pro 32-bit upgrade needs at least 16 GB before it will proceed. Of course, there was the matter of downloading the installer from the Microsoft website too. This took care of system evaluation and paying for the software as well as the actual upgrade itself.
The installation took a few hours with virtual machine reboots along the way. Naturally, the licence key was needed too as well as the selection of a few options though there weren’t many of these. Being able to carry over settings from the pre-exisiting Windows 7 instance certainly helped with this and with making the process smoother too. No software needed reinstatement and it doesn’t feel as if the system has forgotten very much at all, a successful outcome.
Post-upgrade Actions
Just because I had a working Windows 8 instance didn’t mean that there wasn’t more to be done. In fact, it was the post-upgrade sorting that took up more time than the actual installation. For one thing, my digital mapping software wouldn’t work without .Net Framework 3.5 and turning on the operating system feature form the Control Panel fell over at the point where it was being downloaded from the Microsoft Update website. Even removing Avira Internet Security after updating it to the latest version had no effect and it was a finding during the Windows 8 system evaluation process. The solution was to mount the Windows 8 Enterprise ISO installation image that I had and issue the following command from a command prompt running with administrative privileges (it’s all one line though that’s wrapped here):
dism.exe /online /enable-feature /featurename:NetFX3 /Source:d:\sources\sxs /LimitAccess
For sake of assurance regarding compatibility, Avira has been replaced with Trend Micro Titanium Internet Security. The Avira licence won’t go to waste since I have another another home in mind for it. Removing Avira without crashing Windows 8 proved impossible though and necessitating booting Windows 8 into Safe Mode. Because of much faster startup times, that cannot be achieved with a key press at the appropriate moment because the time window is too short now. One solution is to set the Safe Boot tickbox in the Boot tab of Msconfig (or System Configuration as it otherwise calls itself) before the machine is restarted. There may be others but this was the one that I used. With Avira removed, clearing the same setting and rebooting restored normal service.
Dealing with a Dual Personality
One observer has stated that Windows 8 gives you two operating systems for the price of one: the one in the Start screen and the one on the desktop. Having got to wanting to work with one at a time, I decided to make some adjustments. Adding Classic Shell got me back a Start menu and I left out the Windows Explorer (or File Explorer as it is known in Windows 8) and Internet Explorer components. Though Classic Shell will present a desktop like what we have been getting from Windows 7 by sweeping the Start screen out of the way for you, I found that this wasn’t quick enough for my liking so I added Skip Metro Suite to do this and it seemed to do that a little faster. The tool does more than sweeping the Start screen out of the way but I have switched off these functions. Classic Shell also has been configured so the Start screen can be accessed with a press of Windows key but you can have it as you wish. It has updated too so that boot into the desktop should be faster now. As for me, I’ll leave things as they are for now. Even the possibility of using Windows’ own functionality to go directly to the traditional desktop will be left untested while things are left to settle. Tinkering can need a break.
Outcome
After all that effort, I now have a seemingly more stable Windows virtual machine running Windows 8. Flitting between it and other Linux desktop applications has not caused a system freeze so far and that was the result that I wanted. There now is no need to consider having separate Windows and Linux PC’s with a NAS for sharing files between them so that option is well off my wish-list. There are better uses for my money.
Not everyone has had my experience though because I saw a report that one user failed to update a physical machine to Windows 8 and installed Ubuntu instead; they were a Linux user anyway even if they used Fedora more than Ubuntu. It is possible to roll back from Windows 8 to the previous version of Windows because there is a windows.old directory left primarily for that purpose. However, that may not help you if you have a partially operating system that doesn’t allow you to do just that. In time, I’ll remove it using the Disk Clean-up utility by asking it to remove previous Windows installations or running File Explorer with administrator privileges. Somehow, the former approach sounds the safer.
What About Installing Afresh?
While there was a time when I went solely for upgrades when moving from one version of Windows to the next, the annoyance of the process got to me. If I had known that installing the upgrade twice onto a computer with a clean disk would suffice, it would have saved me a lot. Staring from Windows 95 (from the days when you got a full installation disk with a PC and not the rescue media that we get now) and moving through a sequence of successors not only was time consuming but it also revealed the limitations of the first in the series when it came to supporting more recent hardware. It was enough to have me buying the full retailed editions of Windows XP and Windows 7 when they were released; the latter got downloaded directly from Microsoft. These were retail versions that you could move from one computer to another but Windows 8 will not be like that. In fact, you will need to get its System Builder edition from a reseller and that can only be used on one machine. It is the merging of the former retail and OEM product offerings.
What I have been reading is that the market for full retail versions of Windows was not a big one anyway. However, it was how I used to work as you have read above and it does give you a fresh system. Most probably get Windows with a new PC and don’t go building them from scratch like I have done for more than a decade. Maybe the System Builder version would apply to me anyway and it appears to be intended for virtual machine use as well as on physical ones. More care will be needed with those licences by the looks of things and I wonder what needs not to be changed so as not to invalidate a licence. After all, making a mistake might cost between £75 and £120 depending on the edition.
Final Thoughts
So far Windows 8 is treating me well and I have managed to bend to my will too, always a good thing to be able to say. In time, it might be that a System Builder copy could need buying yet but I’ll leave well alone for now. Though I needed new security software, the upgrade still saved me money over a hardware solution to my home computing needs and I have a backup disk on order from Microsoft too. That I have had to spend some time settling things was a means of learning new things for me but others may not be so patient and, with Windows 7 working well enough for most, you have to ask if it’s only curious folk like me who are taking the plunge. Still, the dramatic change has re-energised the PC world in an era when smartphones and tablets have made so much of the running recently. That too is no bad thing because an unchanging technology is one that dies and there are times when big changes are needed, as much as they upset some folk. For Microsoft, this looks like one of them and it’ll be interesting to see where things go from here for PC technology.
