I have Linux server going into a business and the consultant wants all these ports open? Does he need all these ports open just of SSH?
Discovered open port 21/tcp on xxx.xxx.xxx.xxx
Discovered open port 23/tcp on xxx.xxx.xxx.xxx
Discovered open port 901/tcp on xxx.xxx.xxx.xxx
Discovered open port 427/tcp on xxx.xxx.xxx.xxx
Discovered open port 631/tcp on xxx.xxx.xxx.xxx
Discovered open port 111/tcp on xxx.xxx.xxx.xxx
Discovered open port 37/tcp on xxx.xxx.xxx.xxx
Not shown: 1690 closed ports
PORT STATE SERVICE
21/tcp open ftp
23/tcp open telnet
37/tcp open time
111/tcp open rpcbind
427/tcp open svrloc
631/tcp open ipp
901/tcp open samba-swat
==========================

I know - Port 21 is FTP and does not need SSH - he is going to shut this down.
I know - Port 23 is for telnet, he still has to configure SSH instead of telnet
DOES PORT 37 need to be open to connect to NTP Server? I don't need any NTP ports open for Windows Server?
DOES Port 111 need to be open for SSH to work correctly???
What does Port 427 and 631 do?
And needs to shut down 901 ASAP.
Thanks,
Jonathan
