[clug] .bash_aliases and .bashrc

People have posted their favourites before...
Here's a couple I use that I haven't seen elsewhere. Peer review
wouldn't hurt me.

I'd also be interested in what other people find useful.

Replace "su -c" with "sudo" if you use it.


alias Check="su -c 'apt-get update;apt-get -s upgrade | more'"
alias Dmsg="dmesg | grep -i 'warn\|fail\|error\|alert'"
alias Vms="ssh scott <at> vbserver 'vboxmanage list runningvms'"
alias halt="su -c halt" # for systems without a windowmanager

[clug] Programmable title

I have the following in the file.

function fish_title
     echo $_ 'shell '
     tty | cut -c 6-8
     echo ' on line '
     echo (tty) | cut -c 10-

So the terminal window title reads as follows.

"fish shell pts on line 0"

I would like that to substitute instead of "pts" rather "pseudo terminal".
In the case of being a "tty", then I'd like the title to say "terminal"

[clug] Debian Jessie (Testing, ) "no installable kernel was found in the defined APT sources"


I recently tried to install Debian Jess using VMware Workstation 10,
and the installation fails with the error "no installable kernel was
found in the defined APT sources". Has anyone else seen this issue ?

I finally succeeded using the following suggestion from a web site.

The solution I found was to let the installation continue (say Yes to

Re: [clug] NFSv4 "Invalid argument"

Check umask settings maybe? - if it's set to default, then any new file
being created by virt-manager in the ISO directory may not have the
read-write permissions that it needs.

[clug] NFSv4 "Invalid argument"


I am unable to understand how NFS works with user permissions.  Does
anyone have experience with NFS shares in Debian Wheezy and could
explain to me how to manage user permissions for an NFS share ? Maybe
it is not even needed?

I searched the Internet but did not find anything useful, I did find
mentions of libnss-mysql and nfs4_disable_idmapping but I could not
find any detail on how this related to Debian.

[clug] [OT] Supporting a FOSS project

Prof Steve Keen is raising money to keep his programmer going, he’s been working unpaid for last 6 months.
Donations can be made via PayPal from a ‘Donate’ button on the page


The FOSS project was Sourceforge’s Product of the Month last January.
It’s a generic Dynamic Modelling framework, not solely Economics:


I wouldn’t be raising this on-list if I hadn’t already given.

One side of FOSS is using the free software, the other side is supporting the developers.
For those of you who don’t already have a considered “gifting programme”, I encourage you to think
about it.

[clug] Seeking FOSS Hypervisor and Management GUI

     So far I have always created VMs and servers with all files in
the one partition. I have not understood any usefulness for having
separate partitions. My main concern is that I do not know how large
to make the partitions and fear they will fill up as updates are
installed. Some operating systems are like that.  I have one
application that wants to install itself to /usr/share and thus takes
up space I would not have necessarily provided for.  From my limited
understanding, it is /var/log and in particularly /home that are known
to grow large, where as I would expect the other directories (what
should I call them?) like /etc /bin /sbin, etc will only increase
slightly, if at all. I guess partitioning would be a topic of its own.

$ virsh snapshot-list

As for FOSS Hypervisor and Management GUI, my efforts for installing
Virt-Manager 1.1 seemed to have not completely succeeded. When
attempting to use my installation of Virt-Manager 1.1 I found that
there was no Connect/Disconnect for the CDROM, thus I could not add or
remove CD/DVDs or ISOs of CD/DVDs.  In the end I uninstalled and
reinstall Virt-Manager 0.10 which then left me with no GUI for
managing snapshots.

I have yet to try restoring from snapshots or consolidating snapshots,
however I have now used the command line to take snapshots (took a
while for the first snapshot to be taken).  I tried to take a
snapshot of a powered down raw image but of course it would not do
this, the image has to be Qcow2. I also took a live snapshot and a
snapshot of the VM when it was shutdown.

[clug] Virt-Manager & snapshots Vs Xen

I was using KVM with Virt-Manager under Centos 7 and Debian Wheezy and
when I went to take a snapshot of a 6 TB server before applying
updates, and found that there was no snapshot support. For me
snapshots are a base requirement for any virtual machine. For example,
before applying any updates to a virtual server, take snapshot,
install updates, test running software to see nothing as broken,
delete snapshot while consoldiating image, or if the changes cause
issues, roll back the image to the snapshot and live without the
updates until you can apply them without causing issues.

Searching on the Internet I discovered that Virt-Manager >= version
1.0 can take snapshots if the image is qcow2.
The biggest feature we added in virt-manager 1.0 is VM snapshot
support. ... Only works with qcow2 disk images. ... While the overlay
files have to be qcow2, these snapshots will work with any base disk
image. They can also be performed with very little VM downtime, at
least under a second. 

When checking both Debian Jessie and CentOS 7, I discovered that
Virt-Manager was < version 1.0, so using standard packages was not
going to be a useful solution. I will be pleased with these OSs
upgrade to a virt-manager that can support snapshots,but it could be a
long while away.

Going to the Virt-Manager home page, I downloaded the latest verison
of the source code, "virt-manager 1.1.0 Sunday September 07, 2014",

[clug] 2nd drive and auto mountiing

Hi Guys, 

I have a PC running Linux Mint Mate 17 and have a small
dilemma I have yet to solve via forums. 

I have both the Dropbox and
Copy agents running on my PC, and they are pointing to folders on a 1TB
drive installed on the machine, rather than the default boot drive
(which is a small hybrid drive). 

The problem I get is these agents
won't see their respective folders until I open up the file manager and
start browsing the folders and files. 

I have been looking at forums
and tried a few things including changing settings using the Disks GUI
and also manually changing the config files in an editor to auto mount
this drive but get nowhere. I have tried both naming the volume without
and with spaces and haven't had any change either. 

Any ideas on what I
should be doing to solve this? It's one of a small handful of issues
that are preventing enjoyment of using Mint, and probably the most

Thanks in advance, as always
