A few weeks ago I updated a 3 year old installation of Bugzilla to the most recent version, and made these notes along the way. The Bugzilla online documentation is pretty good and my plan was formed using their docs as a guide. Send advance warning to users Log on to site, edit params and [...]

Managing multiple PuTTys
I don't have any Linux cluster servers to look after but do manage 2 Linux server farms. They are similar to clusters in that they are both groups of RHEL servers that all have to have an identical config. The larger of these farms is 12 RHEL 5.3 servers, and to roll out changes to [...]

Install RHEL with Kickstart and no DHCP
I've been installing 16 RHEL 5.3 servers on a DR site, owned by our sister company. There is no DHCP server on the subnet which has stopped us using HP Rapid Deployment Pack to roll out the servers, but it was still possible to use Kickstart, by specifying the IP information as a parameter when booting [...]

Set up a ‘honeypot’ router using Netfilter (iptables)
We're in the process of moving all servers from a legacy flat network to a new server VLAN. Each time a server is moved and is assigned a new IP address, there is a risk that some applications in the building might still try and connect to the server's old IP address rather than the [...]

Get system stats automatically on SSH login
I noticed in recent versions of Ubuntu you get some system stats in a banner message when you connect using SSH. I thought this was pretty useful so have implemented my own version on our Red Hat servers at work. This runs every 5 minutes as a cron job and updates the file /etc/motd (Message [...]

Working with Logical Volumes
I'm actually coming around to Linux LVM - once you get the hang of the concepts and the associated commands it can be a straightforward exercise to extend your existing volumes after adding new physical disks.

Resize swap partitions on Red Hat Linux
First of all a little disclaimer - although I've done this a few times and never had any problems, one should never consider resizing partitions a completely foolproof exercise. Things can go wrong. With regards to swap though, don't worry if your swap partition is destroyed as this will not harm your system - most [...]

Oracle RAC, CentOS and GFS
One thing I'm currently working on is a 2 node CentOS cluster using GFS as the shared file system, with the storage on a fibre attached HP MSA SAN. This is a proof of concept before investing in RHEL AS licences (which will be the better part of £2000). CentOS is free and is intended to clone RHEL as closly [...]

Red Hat Summit 2008 – closing post
In short - it's been good, a valuable use of my time. The presentation throughout the summit was of a very high standard, and this included the catering too. If I had to summarise the summit I would do so using the following 5 buzzwords: 1. Virtualisation. Guess what ...? Red Hat has their own [...]

Spacewalk – Red Hat Satellite for free!
Red Hat have made another important announcement at this years Summit - RH Satellite has been made open source! At first I was excited, because: Red Hat customers can save hundreds of dollars as it's now free - you don't have to buy an RHAS licence for a RH Satellite (that is, unless you want [...]
