| I don't know THAT much about Active Directory and Novell. As far as antivirus, Linux is pretty much immune from windows virii.
There really isn't a commercial firewall. There are though *BSD based firewalls that you can download and install. They can act like a router and do statefull packet inspection. But the main firewall used in Linux is ipchains or iptables. Ipchains was used with the 2.2 kernel release; iptables is used with the current 2.4 kernel. IPTables is quite powerfull. It does stateful inspection and monitors everything coming in and out of your system based on rules you set up or scripts you can use. Here are two links that explain IPTables. The first link is one of - in not THE - best explanation for newbies on how IPTables works. The 2nd explains a lot about it and goes very in depth....more for the experienced user.

samba to act as a Domain Controller but of

| For directory services you have a few choices. The three main ones would be Active Directory (through Samba), NDS (through Novell's software) and LDAP.
There is Linux anti-virus software out there, but I don't use it. For the most part, Linux is immune to viruses. Actually, in Linux, something like Tripwire would probably be more effective then anti-virus software.
There's a ton of open source firewall software out there. A quick google search will turn up many of them. | |

| Thanks for the links to iptables, it's very useful!! But also a much learning curve for me. BTW, Linux is generally immune to virus!? Wow it's amazing to have such nice networking OS! As most people's top security concern is virus attacks, then y still many use Windows in their networks? | |

| There are many reasons, but most seem to boil down to not wanting to learn something new. Others include it not being cost effective to replace existing systems and needing to use a specialized application that's only available for Windows. Specialized applications are the only things keeping me from moving all the workstations over to Unix @ work. |
