A UNIX system probably won't let you open more than one TCP socket on the same port anyhow, the bind() call will fail. But you could just let the server decide what port to use, it'll auto-assign a port in the 32768-65535 range when you bind with port 0.

unconfined

UNCONFINED(8)							     AppArmor							     UNCONFINED(8)

NAME

       aa-unconfined - output a list of processes with tcp or udp ports that do not have AppArmor profiles loaded

SYNOPSIS

       aa-unconfined

DESCRIPTION

       aa-unconfined will use netstat(8) to determine which processes have open network sockets and do not have AppArmor profiles loaded into the
       kernel.

BUGS

       aa-unconfined must be run as root to retrieve the process executable link from the /proc filesystem. This program is susceptible to race
       conditions of several flavours: an unlinked executable will be mishandled; an executable started before a AppArmor profile is loaded will
       not appear in the output, despite running without confinement; a process that dies between the netstat(8) and further checks will be
       mishandled. This program only lists processes using TCP and UDP. In short, this program is unsuitable for forensics use and is provided
       only as an aid to profiling all network-accessible processes in the lab.

       If you find any bugs, please report them to bugzilla at <http://bugzilla.novell.com>.
