Been quite busy lately, hopefully, I am now back at the office after finishing an installation of a high availability active-active firewall cluster, along with DNS, LDAP services and load balancing. A cool project overall, although I loathe Solaris 2.6, and Solaris 8 they have cool things but not for the power user.

Fortunately for the free software :) they asked me to install two load balanced RADIUS servers with Linux. After studying different possibilities, since the main problem is that it needs to be LDAP-enabled, I have found FREERADIUS based on Livingston's radius but with much more capabilities.

I am currently trying to get a nive debian package built that would make installation easier, since they are going now to beta stage, I have also offered them Debian's BTS. I pretend to have them ready so that when they go beta (or even now, in alpha stage) Debian packages will be provided. So, I've cleaned up the (old) Debian subdirs which were related to cistron's radius... I'm very excited about this. This will be the first proyect in SGI that will allow me to put two hardened Debian GNU/Linux server offering Radius and DNS services, in an installation for a client (as a matter of fact my first installation!)

Anyhow, I have investigated the HA options in Linux and I found the Linux-HA project, Legato Cluster, the tool I used is also ported to Linux, but not having VRRP brings out a lot of problems.

I will try to write an article (in spanish) on HA soon, if I find a magazine that can publish it without having any problem with me publishing it also on the internet, on magazines like OpenResources and with a free license.
