Adventures & experiences in contemporary technology
There are times when you might need to drop back to a full screen terminal session from a graphical desktop environment when running Linux. One example that I have encountered is the installation of Nvidia’s own graphics drivers on either Ubuntu or Linux Mint. Another happened to me on Arch Linux when a Cinnamon desktop environment update left me without the ability to open up a terminal window. Then, the full screen command allowed me to add in an alternative terminal emulator and Tech Drive-in’s list came in handy for this. there might have been something to sort on a FreeBSD installation that needed the same treatment. This latter pair happened to me on sessions running within VirtualBox and that has its own needs when it comes to dropping into a full screen command line session and I will come to that later.
When running Linux on a physical PC, the keyboard shortcuts that you are CTRL + ALT + F1 for entering a full screen terminal session and CTRL + ALT + F7 for returning to the graphical desktop again. When you are running a Linux guest in VirtualBox and the host operating system also is Linux, then the aforementioned shortcuts do not work within the virtual machine but instead affect the host. To get the guest operating system to drop into a full screen terminal session, the keyboard shortcut you need is [Host Key] + F1 and the default host key is the right hand CTRL key on your keyboard unless you have assigned to something else as I have. The exit the full screen terminal session and return to the graphical desktop again, the keyboard shortcut is [Host Key] + F7.
All of this works with GNOME and Cinnamon desktop environments running in X sessions and I cannot vouch for anything else unless alternatives like Wayland come my way. Hopefully, this useful functionality applies to those other set-ups too because there are times when a terminal session is needed to recover from a mishap, rare though those thankfully are and they need to be very rare if not non-existent for most users.
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.
The official line from Western Digital is that they do not support the use of their My Book Live NAS drives with Linux or UNIX. However, what that means is that they only develop tools for accessing their products for Windows and maybe OS X. It still doesn’t mean that you cannot access the drive’s configuration settings by pointing your web browser at http://mybooklive.local/. In fact, not having those extra tools is no drawback at all since the drive can be accessed through your file manager of choice under the Network section and the default name is MyBookLive too so you easily can find the thing once it is connected to a router or switch anyway.
Once you are in the servers web configuration area, you can do things like changing its name, updating its firmware, finding out what network has been assigned to it, creating and deleting file shares, password protecting file shares and other things. These are the kinds of things that come in handy if you are going to have a more permanent connection to the NAS from a PC that runs Linux. The steps that I describe have worked on Ubuntu 12.04 and 13.10 with the GNOME desktop environment.
What I was surprised to discover that you cannot just set up a symbolic link that points to a file share. Instead, it needs to be mounted and this can be done from the command line using mount or at start-up with /etc/fstab. For this to happen, you need the Common Internet File System utilities and these are added as follows if you need them (check on the Software Software or in Synaptic):
sudo apt-get install cifs-utils
Once these are added, you can add a line like the following to /etc/fstab:
//[NAS IP address]/[file share name] /[file system mount point] cifs
credentials=[full file location]/.creds,
iocharset=utf8,
sec=ntlm,
gid=1000,
uid=1000,
file_mode=0775,
dir_mode=0775
0 0
Though I have broken it over several lines above, this is one unwrapped line in /etc/fstab with all the fields in square brackets populated for your system and with no brackets around these. Though there are other ways to specify the server, using its IP address is what has given me the most success and this is found under Settings > Network on the web console. Next up is the actual file share name on the NAS and I have used a custom them instead of the default of Public. The NAS file share needs to be mounted to an actual directory in your file system like /media/nas or whatever you like and you will need to create this beforehand. After that, you have to specify the file system and it is cifs instead of more conventional alternatives like ext4 or swap. After this and before the final two space delimited zeroes in the line comes the chunk that deals with the security of the mount point.
What I have done in my case is to have a password protected file share and the user ID and password have been placed in a file in my home area with only the owner having read and write permissions for it (600 in chmod-speak). Preceding the filename with a “.” also affords extra invisibility. That file then is populated with the user ID and password like the following. Of course, the bracketed values have to be replaced with what you have in your case.
username=[NAS file share user ID]
password=[NAS file share password]
With the credentials file created, its options have to be set. First, there is the character set of the file (usually UTF-8 and I got error code 79 when I mistyped this) and the security that is to be applied to the credentials (ntlm in this case). To save having no write access to the mounted file share, the uid and gid for your user needs specification with 1000 being the values for the first non-root user created on a Linux system. After that, it does no harm to set the file and directory permissions because they only can be set at mount time; using chmod, chown and chgrp later on has no effect whatsoever. Here, I have set permissions to read, write and execute for the owner and the user group while only allowing read and execute access for everyone else (that’s 775 in the world of chmod).
All of what I have described here worked for me and had to gleaned from disparate sources like Mount Windows Shares Permanently from the Ubuntu Wiki, another blog entry regarding the permissions settings for a CIFS mount point and an Ubuntu forum posting on mounting CIFS with UTF-8 support. Because of the scattering of information, I just felt that it needed to all together in one place for others to use and I hope that fulfils someone else’s needs in a similar way to mine.
After having Sabayon running on a PC until it came to pieces after an attempted version upgrade, I went away from the Linux distro for a while and Linux Mint now runs on the aforementioned machine. It only was a certain curiosity that got me installing it into a virtual machine on VirtualBox to see if my command line method of keeping the system up to date was the cause or whether rolling or partially-rolling distros have a certain fragility that is not seen in their discrete release counterparts.
Recently that ran into a hitch, the Sabayon package manager Rigo failed to start up for me. After waiting to see if it sorted itself on its own, I looked into returning to those command line ways and that line of enquiry led me to a method of restoring Rigo’s functionality from Sabayon’s wiki page on the underlying Entropy. The first step was to issue a command to become root:
su
That needed the appropriate password and the next command issued updated Sabayon’s repositories:
equo update
Once that had done its thing, it was time to install new versions of Entropy and Rigo:
equo install entropy rigo
With that complete, it was time to exit the root session with the exit command. Then, it was time to try running Rigo and it worked as expected. Any thoughts of adding in the superseded Sulfur (Rigo’s predecessor) were banished on seeing that success.
Within the last week, I set up virtual web server using Arch Linux to satisfy my own curiosity since the DIY nature of Arch means that you can build up exactly what you need without having any real constraints put upon you. What didn’t surprise me about this was that it took me more work than the virtual server that I created using Ubuntu Server but I didn’t expect ProFTPD to be missing from the main repositories. The package can be found in the AUR but I didn’t fancy the prospect of dragging more work on myself so I went with vsftpd (Very Secure FTP Daemon) instead. In contrast to ProFTPD, this is available in the standard repositories and there is a guide to its use in the Arch user documentation.
However, while vsftpd worked well just after installation, connections to the virtual FTP soon failed with FileZilla began issuing uninformative messages. In fact, it was the standard command line FTP client on my Ubuntu machine that was more revealing. It issued the following message that let me to the cause after my engaging the services of Google:
500 OOPS: priv_sock_get_cmd
With version 3.0 of vsftpd, a new feature was introduced and it appears that this has caused problems for a few people. That feature is seccomp sandboxing and it can turned off by adding the following line in /etc/vsftpd.conf:
seccomp_sandbox=NO
That solved my problem and version 3.0.2 of vsftpd should address the issue with seccomp sandboxing anyway. In case, this solution isn’t as robust as it should be because seccomp isn’t supported in the Linux kernel that you are using, turning off the new feature still needs to be an option though.
Having seen Linux Format cover tools like Vagrant and Puppet that manage virtual machines, I have been attracted by the prospect of a virtual web server running on my own PC. Certainly, having the LAMP software stack in a VM means that the corresponding tools don’t need to be added to a host system should its operating system need a fresh installation.
As intriguing as tools like Vagrant may be, I decided that I needed to learn a bit more about getting server instances set up in VirtualBox anyway. Thus, I went and downloaded the latest version of Ubuntu Server and gave that a go. One lesson that I learned was that Bridged Networking needs to be added to the VM before installation of the operating system unless you fancy overcoming the challenge of getting Ubuntu Server to recognise an altered or additional network interface. In my case, I added an extra adapter for the Bridged Networking and left the original in place as NAT. The reason for having Bridged Networking set up is that it allows access to the virtual web server from the host once you know the IP address and that information can be obtained by executing the ifconfig command on the virtual machine.
With the networking sorted, the next step was to install the 64-bit edition of Ubuntu Server. Unlike its desktop counterpart, this is all driven by text menus but remains fairly intuitive and there is hardly anything there that you wouldn’t see with another Linux distribution. A useful addition is the addition of a menu to select the type of server services that you’d like to see installed. From this, I chose the web server and SSH options and I seem to remember that there was a database server option too. If there was an FTP server option, I would have chosen that too but it was no ordeal to add ProFTPd later on anyway.
All of this set was done through the VirtualBox GUI just to keep life more straightforward. Even so, I only selected 12 MB of video memory and was tempted to cut the overall memory back from 512 MB but leaving things be for now. However, what I have begun to do is start and stop the virtual machine from the command line since servers are headless operations anyway. With SSH enabled, there is little need to have the VirtualBox GUI going. The command for starting the server is below:
VBoxManage startvm "Ubuntu Server" --type=headless
There is a VBoxHeadless command for the same end too but VBoxManage does what I need. The startvm option is what tells VBoxManage to start the server and the virtual machine’s name is enclosed in quotes. The --type=headless ensures that no window pops up. To stop the virtual web server cleanly, a command like the following is needed:
VBoxManage controlvm "Ubuntu Server" acpipowerbutton
Again, the VBoxManage command gets used and the acpipowerbutton option ensures that a clean shutdown is performed. Not doing so results in the server not fully starting up according to my experiences thus far. Getting the virtual web server to start and stop with the host machine itself starting and stopping but this looks more complex so I plan to leave things a while before trying that experiment.
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.
While I have a previous posting from 2009 that discusses adding Microsoft’s Core Fonts to the then current version of Fedora, it did strike me that I hadn’t laid out the series of command that were used. Instead, I referred to an external and unofficial Fedora FAQ. That’s still there but I also felt that I was leaving things a little to chance given how websites can disappear quite suddenly.
Even after next to four years, it still amazes me that you cannot install Microsoft’s Core Fonts in Fedora as you would in Ubuntu, Linux Mint or even Debian. Therefore, the following series of steps is as necessary now as it was then.
The first step is to add in a number of precursor applications such as wget for command line file downloading from websites, cabextract for extracting the contents of Windows CAB files, rpmbuild for creating RPM installers and utilities for the XFS file system that chkfontpath needs:
sudo yum -y install rpm-build cabextract ttmkfdir wget xfs
Here, I have gone with terminal commands that use sudo but you could become the superuser (root) for all of this and there are those who believe you should. The -y switch tells yum to go ahead with prompting you for permission before it does any installations. The next step is to download the Microsoft fonts package with wget:
sudo wget http://corefonts.sourceforge.net/msttcorefonts-2.0-1.spec
Once that is done, you need to install the chkfontpath package because the RPM for the fonts cannot be built without it:
sudo rpm -ivh http://dl.atrpms.net/all/chkfontpath
Once that is in place, you are ready to create the RPM file using this command:
sudo rpmbuild -ba msttcorefonts-2.0-1.spec
After the RPM has been created, it is time to install it:
sudo yum install --nogpgcheck ~/rpmbuild/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm
When installation has completed, the process is done. Because I used sudo, all of this happened in my own home area so there was a need for some housekeeping afterwards. If you did it by becoming the root user, then the files would be there instead and that’s the scenario in the online FAQ.
Not being a gaming enthusiast, having to upgrade graphics cards in PC’s is not something that I do very often or even rate as a priority. However, two PC’s in my possession have had that very piece of hardware upgraded on them and it’s not because anything was broken either. My backup machine has seen quite a few Linux distros on there since I built it nearly four years ago. The motherboard is an ASRock K10N78 that sourced from MicroDirect and it has onboard an NVIDIA graphics chip that has performed well if not spectacularly. One glitch that always existed was a less than optimal text rendering in web browsers but that never was enough to get me to add a graphics card to the machine.
More recently, I ran into trouble with Sabayon 13.04 with only the 2D variant of the Cinnamon desktop environment working on it and things getting totally non-functional when a full re-installation of the GNOME edition was attempted. Everything went fine until I added the latest updates to the system when a reboot revealed that it was impossible to boot into a desktop environment. Some will relish this as a challenge but I need to admit that I am not one of those. In fact, I tried out two Arch-based distros on the same PC and got the same results following a system update on each. So, my explorations of Antergos and Manjaro have to continue in virtual machines instead.
To get a working system, I gave Linux Mint 15 Cinnamon a go and that worked a treat. However, I couldn’t ignore that the cutting edge distros that I tried before it all took exception to the onboard NVIDIA graphics. systemd has been implemented in all of these and it seems reasonable to think that it is coming to Linux Mint at some stage in the future so I went about getting a graphics card to add into the machine. Having had good experiences with ATi’s Radeon in the past, I stuck with it even though it now is in the hands of AMD. Not being that fussed so long there was Linux driver support, I picked up a Radeon HD 6450 card from PC World. Adding it into the PC was a simpler of switching off the machine, slotting in the card, closing it up and powering it on again. Only later on did I set the BIOS to look for PCI Express graphics before anything else and I could have got away without doing that. Then, I made use of the Linux Mint Additional Driver applet in its setting panel to add in the proprietary driver before restarting the machine to see if there were any visual benefits. To sort out the web browser font rendering, I used the Fonts applet in the same settings panel and selected full RGBA hinting. The improvement was unmissable if not still like the appearance of fonts on my main machine. Overall, there had been an improvement and a spot of future proofing too.
That tinkering with the standby machine got me wondering about what I had on my main PC. As well as onboard Radeon graphics, it also gained a Radeon 4650 card for which 3D support wasn’t being made available by Ubuntu GNOME 12.10 or 13.04 to VMware Player and it wasn’t happy about this when a virtual machine was set to have 3D support. Adding the latest fglrx driver only ensured that I got a command line instead of a graphical interface. Issuing one of the following commands and rebooting was the only remedy:
sudo apt-get remove fglrx
sudo apt-get remove fglrx-updates
Looking at the AMD website revealed that they no longer support 2000, 3000 or 4000 series Radeon cards with their latest Catalyst driver the last version that did not install on my machine since it was built for version 3.4.x of the Linux kernel. A new graphics card then was in order if I wanted 3D graphics in VWware VM’s and both GNOME and Cinnamon appear to need this capability. Another ASUS card, a Radeon HD 6670, duly was acquired and installed in a manner similar to the Radeon HD 6450 on the standby PC. Apart from not needing to alter the font rendering (there is a Font tab on Gnome Tweak Tool where this can be set), the only real exception was to add the Jockey software to my main PC for installation of the proprietary Radeon driver. The following command does this:
sudo apt-get install jockey-kde
When that was done I issue the jockey-kde command and selected the first entry on the list. The machine worked as it should on restarting apart from an AMD message at the bottom right hand corner bemoaning unrecognised hardware. There had been two entries on that Jockey list with exactly the same name so it was time to select the second of these and see how it went. On restarting, the incompatibility message had gone and all was well. VMware even started virtual machines with 3D support without any messages so the upgrade did the needful there.
Hearing of someone doing two PC graphics card upgrades in a weekend may make you see them as an enthusiast but my disinterest in computer gaming belies this. Maybe it highlights that Linux operating systems need 3D more than might be expected. The Cinnamon desktop environment now issues messages if it is operating in 2D mode with software 3D rendering and GNOME always had the tendency to fall back to classic mode, as it had been doing when Sabayon was installed on my standby PC. However, there remain cases where Linux can rejuvenate older hardware and I installed Lubuntu onto a machine with 10 year old technology on there (an 1100 MHz Athlon CPU, 1GB of RAM and 60GB of hard drive space in case dating from 1998) and it works surprisingly well too.
It seems that having fancier desktop environments like GNOME Shell and Cinnamon means having the hardware on which it could run. For a while, I have been tempted by the possibility of a new PC since even my main machine is not far from four years old either. However, I also spied a CPU, motherboard and RAM bundle featuring an Intel Core i5-4670 CPU, 8GB of Corsair Vengence Pro Blue memory and a Gigabyte Z87-HD3 ATX motherboard included as part of a pre-built bundle (with a heatsink and fan for the CPU) for around £420. Even for someone who has used AMD CPU’s since 1998, that does look tempting but I’ll hold off before making any such upgrade decisions. Apart from exercising sensible spending restraint, waiting for Linux UEFI support to mature a little more may be no bad idea either.
Update 2013-06-23: The new graphics card in my main machine is working as it should and has reduced the number of system error report messages turning up too; maybe Ubuntu GNOME 13.04 didn’t fancy the old graphics card all that much. A rogue .fonts.conf file was found in my home area on the standby machine and removing it has improved how fonts are displayed on there immeasurably. If you find one on your system, it’s worth doing the same or renaming it to see if it helps. Otherwise, tinkering with the font rendering settings is another beneficial act and it even helps on Debian 6 too and that uses GNOME 2! Seeing what happens on Debian 7.1 could be something that I go testing sometime.
It’s amazing what ideas Linux gives that you wouldn’t encounter that clearly in the world of Windows. One of these is output and command line history so a script can be created. In the Windows world, this would be called a batch file. Linux usefully has the history command and it does the needful for taking a snapshot like so:
history > ~/commands.sh
All of the commands stored in a terminal’s command history get stored in the commands.sh in the user’s home area. The command for doing the same thing from the Windows command line is not as obvious because it uses the doskey command that is intended for command line macro writing and execution. Usefully, it has a history option that tells it to output all the commands issued in a command line session. Unless, you create a file with them in there, there seems to be no way to store all those commands across sessions, unlike UNIX and Linux. Therefore, a command like the following is a partial solution that is more permanent than using the F7 key on your keyboard:
doskey /history > c:\commands.bat
Windows Powershell has something similar too and it even has aliases of history and even h. All Powershell scripts have file extensions of ps1 and the example below follows that scheme:
get-history > c:\commands.ps1
However, I believe that even Powershell doesn’t carry over command history between sessions though Microsoft are working on adding this useful functionality. They could co-opt Cygwin of course but that doesn’t seem to be their way of going about things.
