NetworkManager is one of those things in the linux world that many SysAdmins hate. It’s a bit like your mother-in-law; it means well but is really really irritating. On any new system I set up, the first thing I do is get rid of it, and just use the old-school config files way of setting [...]
I haven’t posted for a while about my Scientific Linux 6.0 setup on my Thinkpad R60. It all kind of goes well. However SL 6.0 is kind of old, 6.1 has been out for a while and 6.2 is on the horizon (UPDATE: Ooops, I see its now out!). So I thought I’d upgrade to [...]
So I’ve had Scientific Linux 6.0 64 bit on my Thinkpad R60 for a while now, and for the most part it has been fine. But one thing that has really annoyed me is that everytime there is a kernel update, I notice that the laptop fan is stuck on (when the system is essentially [...]
So, as per my previous post, I was searching for an upgrade path for my Thinkpad R60 virtualistation server running Debian Lenny. I’d tried upgrading to Squeeze a few times … and didn’t like it … always reverting back to Lenny. So after trying a few different distros/virtualisation hypervisors (using a spare disk), I settled [...]
So, my main virtualisation machine here at home is a Thinkpad R60 running Debian Lenny, with KVM as the virtualisation engine. This has been my main ‘server’ host for over a year and a half now. I have quite a few VMs on it, but most are for testing out stuff, so there is only [...]
One thing that would be nice to have in linux LVM is the ability to take a snapshot of a logical volume, make some changes then ‘roll back’ to the state preserved in the snapshot. If you look at the current set of lv commands on most linux distros there is no such option to [...]
For some time now, my old Thinkpad T42 has been running as a lightweight server at home. Some people think I’m a bit mad using a laptop as a server, but my vague reasons are a) they’re generally quiet, b) they don’t use a heap of power, c) the battery is in some ways a [...]
My main linux box here is about 3 years old now. The case is older, but I bought the cpu, motherboard, graphics card and some of the ram when the first Core 2 Duo’s were announced. It was expensive at the time, but it was well worth it. I bought a 1.86GHz E6300 C2D (not [...]
I’d read about quite a few new features in the linux 2.6.31 kernel,so I thought I’d download the official source for 2.6.31 from kernel.org and build a custom kernel on my Debian Lenny 64 bit core2duo system. Thats the usual make-kpkg melarchy which takes an eternity. It took me a while to get 2.6.31 to [...]
There are quite a lot of ways to get a remote graphical desktop when connecting to a unix system. X windows itself has always been a network based protocol, so if you had an X terminal or a PC running an X server, or even another unix system, you could always connect in that way. [...]
