open ports?
Following ports are opened according to nmap on a default cpanel server installation.
PORT STATE SERVICE
1/tcp open tcpmux
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
26/tcp open unknown
53/tcp open domain
80/tcp open http
110/tcp open pop3
111/tcp open rpcbind
143/tcp open imap
443/tcp open https
465/tcp open smtps
783/tcp open hp-alarm-mgr
953/tcp open rndc
993/tcp open imaps
995/tcp open pop3s
3306/tcp open mysql
6666/tcp open irc-serv
Should I allow all the above ports on my iptables rules?
For example 6666 port is for irc which I am not gonna use, can I reject that or I will be in trouble with cpanel etc....
Also tcpmux, hp-alarm-mgr, should be closed?
On port 26 as I can see with nmap it runs the ftp server.
Many thanks
