    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

    netstat -nlp

    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* 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?

    lsof -i :<port>

    that will tell you what process is using the port (if lsof is installed)
