I have recently installed two Ubuntu Server machines and I would like to find the open ports in the machine.
When I run nmap from my machine (Ubuntu 11.10) I observed that both servers have
135/tcp filtered msrpc
4444/tcp filtered krb524
4662/tcp filtered edonkey
5000/tcp filtered upnp
5631/tcp filtered pcanywheredata
I have never opened those ports. I only installed LAMP and SAMBA. Why are these ports open?
The complete list of the open ports are:
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
80/tcp open http
110/tcp open pop3
135/tcp filtered msrpc
139/tcp open netbios-ssn
143/tcp open imap
445/tcp open microsoft-ds
993/tcp open imaps
995/tcp open pop3s
4444/tcp filtered krb524
4662/tcp filtered edonkey
5000/tcp filtered upnp
5631/tcp filtered pcanywheredata
The question is why are these ports open: 135/tcp filtered msrpc, 4444/tcp filtered krb524, 4662/tcp filtered edonkey. 5000/tcp filtered upnp, 5631/tcp filtered pcanywheredata. I have never opened those ports. I only installed LAMP and SAMBA.
Does that list seem secure?
