closing a socket using it's port name.

Hi,

I want to close a an ephemeral port so i'll be able to bind it for recvfrom() (udp).
I noticed that shutdown() receives a sockfd but I only got the port's name.

Any ideas how do I do that?

From a sysadmin's standpoint, you could run something like "fuser":

    # fuser -n tcp 8000
    8000/tcp:            29178

    # ps -fp 29178    
    UID        PID  PPID  C STIME TTY          TIME CMD
    102      29178  8150  0 07:48 pts/5    00:00:00 ./junkbuster junkbstr.ini

From there, you could kill that process (or have fuser do it via -k) which would open up that tcp or udp socket.
