There seems to be a process called "cslistener" on my machine that is listening on port 9000. A scan using nmap resulted in this, where 172.29.137.150 is the address of my PC.
Nmap scan report for 172.29.137.150 Host is up (0.000013s latency). Not shown: 993 closed ports PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 139/tcp open netbios-ssn 443/tcp open https 445/tcp open microsoft-ds 9000/tcp open cslistener 10000/tcp open snet-sensor-mgmt
What's going on here? I'm on ubuntu 12.04.
