Remove Sieve mail filter deamon on port 2000?

[bigEsmurf]

Hi All,

For a test of software on our server I need to run sslproxy on port 2000. When I run it, I get an error that the port is in use, and after some searching with nmap and "cat /etc/services | grep 2000" I found that sieve is using the port:

sieve 2000/tcp # Sieve Mail Filter Daemon
sieve 2000/udp # Sieve Mail Filter Daemon

What is sieve, what is it used for, and can I remove it or change it's port somehow?

/etc/services doesnt mean something is using that port that just maps common service names to ports.

netstat -na | grep -i list | grep 2000

should show you if anything is listening on the port.

You might want to try lsof too.

Are you sure you dont have a rootkit and hidden processes?

Nothing that I know of should be running on port 2000 by default.

Are you trying to bind the port as a unpriviledged user or as root?
