I recently co-located a new server to find that I was given one ‘main ip’ on subnet X and all my additional IPs were on subnet Y. This has happened in the past but the Datacentre setup usually has a gateway on each subnet to allow for internet access. This was not the case in [...]

Our university firewall is shockingly restrictive, this meant that recently I couldn’t even download a game that I bought using Steam (this is my first time using the Steam system).
There instructions will also work for any program you might be unable to use behind a firewall in a university that’s still old-fashioned enough to limit [...]

There’s a great looking Dell sale on at the moment, ~£250 off all servers. I think I need one..

Add the following to your spamassassin/local.cf – sorted:
# Stop outgoing messages being marked as spam
header LOCAL_RCVD Received =~ /.*\(\S+\.henricook\.com\s+\[.*\]\)/
describe LOCAL_RCVD Received from local machine
score LOCAL_RCVD -500
Took me a while to find! Simply looks for <foo>.henricook.com in the received line (i.e. received for outgoing) and -500’s the spam score making it near impossible to be classified [...]

Wow, possibly the largest title ever. This is something that i’ve done fairly recently, I wanted a phone for my business that wasn’t a mobile and my options appear to be costly forwarding to my mobile (when i’ll probably be near my PC anyway) or getting calls routed to a home phone line (which would [...]

The following error is something that took me absolutely ages to resolve so I thought i’d post it for others to read about, the error as seen in my Apache error log:
install_driver(mysql) failed: Can’t load ‘/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/DBD/mysql/mysql.so’ for module DBD::mysql: /usr/lib/libmysqlclient.so.14: version `libmysqlclient_14′ not found (required by /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/DBD/mysql/mysql.so) at /usr/lib/perl5/5.8.8/i386-linux-thread-multi/DynaLoader.pm line 230.
To fix this, I had [...]

After spending a ridiculous amount on replacing network cards as described previously, the problem was made a little better.
Imagine my horror when I finally discover from someone in ##xen on irc.freenode.org that the Ubuntu Xen packages are absolute bollocks. My machine running Xen crashed up to 5 times a day, whenever high I/O load occurred. [...]

I’ve just finished installing a new Xen Server in my datacentre. I am now installing a 3rd network card in an attempt to find one that’s compatible. It’s been an absolute nightmare.
For those who are clever enough to be reading this, and cleverly researching before hand – my NIC history:
