Dropping Xen
Well I’ve had enough of Xen - I’ve recently moved a disk from hdd to hdc and since I referred to it in a xen domain, when I tried to start that domain, it hung for several minutes (other domains also seemed to stop responding for a while) and then failed with:
abridgett@ripley:/var/log/xen$ Error: Device 2081 [...]

LinuxWorld Expo - San Francisco
At the end of this week I’m off to LinuxWorld Expo in San Francisco.
I’ll be there as we are now partners of Altinity. Altinity make Opsview - which is a customised Nagios. In particular it is much easier to setup and administer - there are many great features including:
* [...]

Java “Out of swap space” rubbish
Occasionally we’ve had this during a tomcat restart at a customer site.
After a little while we rebooted. Next time it occurred on a test platform and I could check shared memory (using ipcs and ipcrm commands), all files (temporary files etc). Then I restorted to “strace” which allowed the app to start. [...]

bye bye Xen
Well it looks like it’s time to plan a replacement server. My trusty Ideq Biostar which I’ve had since 2004/2005 is still fine, however there are some bugs for which I need to upgrade the kernel and it’s stuck at 2.6.18 since Xen hasn’t been ported to a newer kernel. I’ve backported a [...]

XP roadmap
So Windows XP (due to go out of support in 2008) has had its support extended to 2010 for mini-laptops. Odd given that service pack 3 has only just come out for it. Now they announce it will also be extended for desktops.
I have this picture in my mind of Microsoft adding a [...]

Asterisk
I’ve decided to play around with asterisk a bit more, partly for interest, partly as we could do with cheaper conferencing at work - we spend a fair amount of money on it. I’ve started making notes on my setup but they are very rough ATM.
Things I’ve discovered so far:
xen DomU’s can’t run [...]

Or “Oh bugger”.
In short, Debian made a slight change to openssl which means that all keys (SSH user and host keys, X509 keys and certs, OpenVPN passwords) have not been sufficiently random for the last few years.
This is a _lot_ of effort to correct:
remove all bad ssh keys and regenerate [...]

no dots in cron.d
Just a short entry in case anyone else gets bitten by this one. File in /etc/cron.d are processed according to run-parts convention - this means they must not contain dots. script.live has now been renamed script-live!

Why aren’t schools using Open Source?
I’m doing a little research for a meeting with John Denham - Secretary of State for Innovation, Universities and Skills. I was aware of the BECTA reports, but I’ve just been doing a little calculation.
Using the numbers from a report published in 2000, there are 18,158 primary schools and 3,550 secondary schools in [...]

Updates
Well planet is back up and running on the LUG box.
Lurker ain’t happy (still) - it complains about permissions but they are fine. I’ve added some debug to see what is going on.
Not looked at gallery yet.
One reason I’ve not finished these yet is that my folks came down for a visit. I’ve learnt [...]
