There are services that I know I need, such as samba-swat, sun-manageconsole, abyss, vnc, etc. This server offers http and samba services, but not much else. Can someone shed some light on what the echo, discard, daytime, chargen services are for, and if there is any potential of hosing the machine if these are disabled? I am trying to lockdown this machine against intrusions.
# netstat -lnpThis command will give you information about which ports are open and which processes listen on them. However if you notice difference in the output of that command and the output of the nmap (e.g. nmap shows that 7100 is open, but netstat thinks it's not open) then you should consider that your machine might have been cracked.
Also, I would like to know what file(s) hold info on which services use which ports.
