analisi porte aperte sul server..

["Wannabe.mail" <wannabe.mail@libero.it>]

ciao,
con nmap ho fatto un'analisi delle porte aperte sul mio server.

Ecco il risultato:

PORT    STATE SERVICE
23/tcp  open  telnet
25/tcp  open  smtp
80/tcp  open  http
110/tcp open  pop3
111/tcp open  rpcbind
113/tcp open  auth
143/tcp open  imap
631/tcp open  ipp


Ricapitolando:

PORT    STATE SERVICE
23/tcp  open  telnet >>>>>>>>>>>>>>>     Servizio Telnet per 
collegamenti remoti verso il server ( telnetd )
25/tcp  open  smtp  >>>>>>>>>>>>>>>     Servizio SMTP - Invio mail 
(Postfix )
80/tcp  open  http   >>>>>>>>>>>>>>>      Http - ( Apache )
110/tcp open  pop3 >>>>>>>>>>>>>>>      Pop3 - ( Dovecot )
111/tcp open  rpcbind >>>>>>>>>>>>>      ???????????? ( Nn so )
113/tcp open  auth  >>>>>>>>>>>>>>>     ???????????? ( Nn so )
143/tcp open  imap >>>>>>>>>>>>>>>      Imap - ( Dovecot )
631/tcp open  ipp    >>>>>>>>>>>>>>>      ???????????? ( Nn so )


Qualcuno mi sa dire a che cosa corrispondono i tre servizi che non conosco?

Grazie
