Unkown Open Port
Today I just ran a check of all my open ports with nmap and I found one unkown port open -- port no. 32768. So I tried to check the corresponding application which opened it by the command
but even this simply showed a dash in place of the process no. of the process listening on that port. The entry was something like this --
tcp 0 0 0.0.0.0:32768 0.0.0.0:* LISTEN -
Finally I tried fuser to get the process no.--
fuser -n tcp 32768
But it did not return anything at all which implies that that port is not opened by any application. Now how is this possible. How and why is that port open? How can I find out?
Do you play the game Joint Operations Typhoon Rising?
lsof -i :<port>
that will tell you what process is using the port (if lsof is installed)
