I’ve been using Munin for myself to replace Cacti and been generally liking it. As someone who has used Cacti for a long time I never seem to get my head around it totally. Something would go wrong and it would never be easy for me to find out just what was failing as I thought it should be. But really what I liked was the ability to send me some email alerts. My monitoring needs are not grandiose so this was fine for me. Except the default email alerts aren’t the easiest to read, but they are short.

Exim & Dovecot mailserver with Active Directory
Following on from getting Debian working with Active Directory for account authorisation I had need to set up Exim with Dovecot for a mail server. Obviously I want to use the Active Directory to keep all the accounts as before, but I also want it to keep all my email aliases.
Acronym overload: Migrating Xen PVM hosts to KVM HVM hosts
I have a server I’ve been using which does not have hardware virtualisaton (HVM). On this I’ve been using Xen paravirtualisation (PVM). This is all well and good, except the server is approaching six years old and I’ve a shiney new server that does support HVM that I’d like to use.
Warning: Acronym overload ahead…
Fun with KVM on Squeeze

The new server has hardware virtualisation so I thought I would try KVM as it seems more in vogue these days. There is a useful KVM/Debian Squeeze Howto on HowtoForge.com which gave me a good grounding on most things.
It seems quite good so far, but not without some minor issues.

Debian Squeeze, Active Directory & Samba
[Updated 30/10/2012 to include a configuration option to stop timeout errors]
This originally started as a note to myself should I ever need to revisit this, but I have expanded it a bit to make it a bit more general in case others might find it useful.
I use Debian Squeeze on our Linux servers. I have been trying to get them to authenticate off of our Active Directory/Windows Server 2008. Previously we used OpenLDAP and this worked well, but with AD I’d rather have one authentication system. One password rather than two.
My experience with Winbind has not been favourable. Despite documentation and plenty of blogs with well written examples of how to do it I could not get it to work for me. Most of what is written is from there.
