Securing Linux is a lot easier on *nix than editing M$-Win registry items to shut off DCOM's use of port 135 and various other services like tcp/ip Netbios helper.. I would recommend using nmap "its cross platform and will show any open ports on your system..Also Ethereal will catch incoming/outgoing packets in real time.. And, on *nix I would choose Fedora simply because it has the better SELinux features constantly added for added security of course. If you need to tighten a *nix box, I've been called the most paranoid. and have a laundry list of how to protect your box. example: forward port 113 into a non-used ip address on your router and monitor ip's that try to use that ip. What this does is stealths 113 and port 80 even if port 80 is open to the world and a server is behind it... -- Regards, Euman Registered Linux User #380358 Thawte WOT S/Mime = 74:E8:C7:D0:6E:5B:4F:8F:91:9E:72:2E:61:FA:DC:D2 GPG Fingerprint = 1DF4 30A8 54FA BBF4 E763 06FD 9FE4 39E8 87B0 7ECB --=-D+xRkHvaLALvqb6NHCMh Content-Type: application/x-pkcs7-signature; name=smime.p7s Content-Disposition: attachment; filename=smime.p7s
