Ports Open or Closed

wcn · 05-29-2004, 10:39 AM

I have recently installed Mandrake 10. All has been going well. Today I have been trying to setup an email server. The server that I am setting up is not important.

The problem that I am having is that 2 ports that I need are not available (port 25 and 110).

I have checked with nstat -a and I cannot find any information on these 2 ports.

I have checked with nmap and both 25 and 110 are in the state of open.

I have temporarily setup my server on ports 8025 and 8110 and all is fine. The question is, how do I find out what is hogging up ports 25 and 110?

Thanks in advance..

You could try "netstat -ap", that displays on my box:

tcp 0 0 *:ssh *:* LISTEN 659/sshd

That will tell you what PID is using that port, so in this case, ssh is being used by (suprise suprise!) sshd :)

check /etc/inetd.conf and your /etc/init.d folder for mail-servers

Here is my netstat -ap (what is on port 80 and 110?)

the other one is being listed as master.

Just a small comment: use netstat -natp instead of netstat -ap to see the servers listening for "outside" connections. lsof -i is also nice.
