Description
FreeBSD Systems Administration
11 yrs
5.0
2008
I ran and supported all the FreeBSD versions from 2.2.8 to 7.0. Though I recently switched to Linux and Solaris, I still know enough to be dangerous and dare to call myself expert :) The FreeBSD project made absolutely glorious return (scalability-wise) with 7.0, so, I'm looking forward to get some new tasks based on this even-better now platform.
Linux Systems Administration
13 yrs
5.0
2008
I'm running linux since the times when version
0.99pl11 was new (Slackware 1.0 :) )
Brainbench certified in General Linux Administration (Master) and RHEL 5 Administration (Master)

Novell Netware
2 yrs
2.0
2001
The beast is dead :) For good. Though, I can give you some help with it if you are absolutely desperately need it :)
OpenBSD Systems Administration
6 yrs
4.0
2008
Marked as Proficient, as I've never used OpenBSD for anything but firewalls in production environment, as none of my clients was paranoid enough to ask for OpenBSD on the general-purpose server. Though I still hope to meet one.
My favourite unix variant.
Solaris Systems Administration
6 yrs
4.0
2008
Though Solaris is not the primary unix I'm dealing with, I do know enough to solve most problems and do understand and know how to use Solaris-specific features.
TCP/IP Networking
13 yrs
5.0
2008
I'd better mention what I CAN'T do about TCP/IP networking (as I did heaps of stuff, including writing real-time DDoS detection and mitigation software in C :) ):
- I'm not comfortable with 'big iron' like cisco and juniper
- My routing skills do not go beyond static routes+policy routing. I.e. - no IGMP etc. I never had a chance (same with cisco and juniper)
- I've never dealt with ipv6
