What is using port 40292 on Ubuntu 10.4?!

LAN-Dominator.nl · 06-10-2010, 03:29 PM

Watching Logs and event reports, clearly something is trying to use my 40292 port.

I tried to find out more about the Port, by temporary starting FireStarter.
Unfortunately my search kept me stranded with the same question after 3 hours.

Does anybody here knows any thing about that certain port usage?

Hi -

You can use "lsof" to identify what process(s) are using the port.

'Hope that helps .. PSM

Try

Code:

netstat -alpn|grep ":40292"

Should give you the process name and PID

tcpdump is also an option.

lsof will also identify the UDP port - an example of the lsof:

Code:

root@e54:~# lsof +i:39346
COMMAND    PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
VirtualBo 5175 joseph   52u  IPv4  31174      0t0  UDP *:39346
