113 is used by the IDENTD, what shouldn't pose a threath to your system.

139 is used by the SMB protocol which SAMBA implements on Unix. I would
definatly firewall this out, or just don't run the Samba deamon. If you
don't want to run this, just use tksysv to make sure it's not in your
startup scripts. (/etc/rc.d/rc3.d or /etc/rc.d/rc5.d; depends if you
auto startup X)

As for port 515 i don't know. Maybe someone else on the list.

Good Luck,

Jeroen
