websites that work for you
I needed to setup a VPN client connection on a headless system where the VPN is slow and so I want to route the minimal amount of traffic through it. I need DNS to use the VPN but only for one domain.
This is my setup using pptp and dnsmasq (tested on centOS)
Basic VPN config is here /etc/ppp/peers/office
One of those things that happens from time to time on a dual boot system...
Windows breaks grub, usually if I've reinstalled windows, this can lead to a unbootable system.
Boot from a Ubuntu (or other distro) live disk or USB stick.
Figure out which your disks and partitions are.
sudo mount /dev/sdXY /mnt
# if there is a boot partition
sudo mount /dev/sdUV /mnt/boot
sudo grub-install --recheck --root-directory=/mnt /dev/sdZ
When you reboot grub should be back to normal.
If you want to create custom rpms and install then with the usual automated dependency management you'll need your own yum repository. This is just the RPMS and metadata in the format of static xml files served by a webserver.
On a project I'm working on at the moment we have a problem, files are going missing.
We don't know which part of the system could be trashing these files (user uploaded images in this case) and they are on a shared filesystem so there are plenty of places to point fingers.
I've discovered a very handy toolset inotify-tools Which hooks into the linix kernel and allows you to monitor actions like file deletion.
I had a centos VM that I hadn't used in a while, I think I cloned it from another version.
When I came to use it again I had no network andtrying to start the network I got the error message in the title.
There seem to be a few issues
Firstly netowrking isn't endabled by default

I usually manage website deployment with bash scripts that run remote commands on the servers
In order that I can see what is going on and debug any errors verbose output is useful.
Running "bash -ex" causes each line to be output as it progresses and halt on any error so that you don't miss it.
within the remote command "set -x" cuase bash to echo all commands
#!/bin/bash -ex
ssh -T user@server << EOF
set -x
echo foo > /dev/null
EOFOne of those posts for myself in case I need to come back to this later
I have a new PC which is very fast apart from problems with disc access seeming slow (and the disks being physically noisy)
The following related links led me to try a solution

/etc/fstab

NB adding barrier=0 here seems to have solved the problem
The music player banshee which is part of the default Ubuntu setup pops up a message each time a new track starts playing.
To turn this off
Very annoying - the option to turn off notifications is hidden on a menu you can't get to by default.
I want the drupal user uploaded files to be manageable by both apache and a non-root user
In my case I'm using hudson to rebuild the site with data and "files" from live periodically.
So I have added the apache group to the hudson user
/usr/sbin/usermod -G hudson,apache hudson
/etc/init.d/hudson restartand set the umask for apache so that files are created group writebale
For Redhat
echo "umask 002" >> /etc/sysconfig/httpd
/etc/init.d/httpd restartFor Debian/Ubuntu
echo "umask 002" >> /etc/apache2/envvars
It wasn't immediately obvious to me
What I needed to do to get blutooth audio working was to install the blueman package
After that configuration via GUI was pretty straightforward
Now I have fantastic sound via my bluetooth enabled HIFI :-)
