[NTLUG:Discuss] open ports

[Kyle_Davenport@compusa.com]

You cannot close those ports and run x-windows, but you can secure them with an
entry for localhosts in /etc/hosts.allow and using ipchains.

There is a kernel mod out there that will present random responses to port scans
to foil those scanners.   Sorry I don't know where it is, but I would start with
the secure linux distribution, http://www.kha0s.org/.

Subject:  [NTLUG:Discuss] open ports






In the process of checking my machine for security flaws I noticed that my auth
& X11 port are open. How should I go about closing these ports? Also nmap can
tell what OS & Kernel the machine is running, does anyone know how I can prevent
nmap or other scanners from detecting the OS?
