When I nmap my computer I get this port open with this text

8082/tcp open blackice-alerts

Do anyone of you know what this blackice-alerts is

netstat reveal this

Any ideas .......?

Just in case it's some web server: did you try localhost:8082 ? – Arjan Nov 2 '09 at 18:57

Are you sure that's what is listening on 8082, rather than what nmap is guessing? Try:

 sudo lsof -i tcp:8082

Ubuntu has a "policy" of not having any ports open for security purposes. On a LiveCD of Ubuntu 9.10, I don't see port 8082 open, so something you installed started a service on this port. To find out what has it open, run netstat with the -p flag with sudo:

sudo netstat -plant

The last column will show a PID and a programs process name. You can find more detail about the running process by the PID listed from the output with:

sudo lsof -p:PID

(Where PID is the number)

You can find out what package installed that program with dpkg -S

dpkg -S

I had a web-proxy (webscarab) running on localhost and that was running on 8082. Netstat showed a java process (I guess webscarab is written in java and hence jvm is being invoked).

Closing Webscarab closed the port too.
