Hi igorek24,
Thanks for the heads up about Webmin. I don't think I have much to worry about as it is only available from the LAN and the LAN is behind Smoothwall Express, which is why I'm not too concerned about not running the firewall on the Centos box. Hopefully I'm not being too complacent
I'm not up-to-speed on selinux, so for me it's adding another layer to the learning curve but I do intend to enable the firewall and selinux when I've got my head round it. Might be while, I'm at the stage of my life cycle where I'm now in the slow learners club
I can see why you like Centos so much, I've only got enough Linux knowledge to get me into trouble and so far haven't broken it. It's certainly growing on me but my native tongue is Microsoft and I'm a big fan of GUI's. I was going to go for Ubuntu server but think that Centos is definitely the better choice in robustness & stability.
Are your servers mostly member servers? Do you use any as a DC and/or DHCP server?
For me, it's like going forward to the past! In another life, I used to admin SCO servers (about 150+) and was part of a team that were migrating the SCO boxes to NT4 and then Win 2000. It's amazing how things come round and reverse! The main thing I can remember about *nix stuff is my hatred of Vi
