After a long time with no “modern” Linux Kernel available in Debian or Ubuntu for usage as Xen Dom0, the “Big Bang” release has been uploaded to Debian unstable. This actually means all the hardware support etc. from Kernel 2.6.32 AND Xen a simple ‘apt-get install’ away. Maybe we can even get Ubuntu Karmic DomUs running…
A few links for the config-burdened sysadmins:
* Dpsyco: Debian packages of system configurations
* Puppet: centralised configuration management for networks
* IsiSetup: modular revision control for config files
* Cfg: Configuration File Tracking, emitting Puppet configs
ADVICE: Don’t upgrade to Ubuntu Feisty Fawn if you’re using LILO on a degregated software RAID. Resync first, as told by this forum posting… I had to boot an old kernel (and who remembers which key to press to show the LILO menu?) The kernel packages weren’t able to build the initramfs and running lilo didn’t help, either. Resyncing was the key to success, though.
On of the most useful Feisty Fawn improvements is the integration of avahi. Using MDNS, you may address systems on the same network segment using a hostname instead of IP addresses. It’s dead simple: hostname.local:
shuerlimann@leni:~/cyt.ch/projects$ ping otherhost.local
PING otherhost.local (192.168.200.225) 56(84) bytes of data.
64 bytes from anon-client225.intern.example.com (192.168.200.225): icmp_seq=1 ttl=64 time=36.5 ms
Just make sure you allow incoming connections on UDP port 5353.
It looks like systems updated from Edgy Eft don’t get this feature by default. Please give me some hints how to do that if you know how to do it:-)
