Bind and Listen on an Available Port in a Range

See more Socket/SSL/TLS Examples

Demonstrates Socket.BindAndListenPortRange, which searches an inclusive port range for an available TCP port, binds it, and begins listening. It returns the selected port, or -1 on failure.

import sys
import chilkat

socket = chilkat.CkSocket()

#  Search the inclusive port range for an available TCP port, bind it, and begin listening.  The
#  method returns the selected port, or -1 when no port can be bound.
boundPort = socket.BindAndListenPortRange(5000,5100,25)
if (boundPort < 0):
    print(socket.lastErrorText())
    sys.exit()

print("Listening on port " + str(boundPort))
