I got this little script from Ghostdog74 from our forum, modified it a bit to suit my needs :

Code:

#!/usr/bin/python

import socket
import sys

if ( len(sys.argv) != 2 ):
    print "Usage: " + sys.argv[0] + " you must enter IP or FQDN as argument"
    sys.exit(1)

remote_host = sys.argv[1]

for remote_port in [21,22,23,80,139,139,389,443,445,3128,3306,3389]:
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        sock.settimeout(20)
        try:
                sock.connect((remote_host, remote_port))
        except Exception,e:
                print "%d closed " % remote_port
        else:
                print "%d open" % remote_port
        sock.close()

- change the ports as you wish.
Implementing nmap for ports monitoring is also good idea.

listen

listen(3SOCKET) 					     Sockets Library Functions						   listen(3SOCKET)

NAME

       listen - listen for connections on a socket

SYNOPSIS

       cc [ flag ... ] file ... -lsocket  -lnsl  [ library ... ]
       #include <sys/types.h>
       #include <sys/socket.h>

       int listen(int s, int backlog);

DESCRIPTION

       To  accept  connections, a socket is first created with	socket(3SOCKET), a backlog for incoming connections is specified with listen() and
       then the connections are accepted with  accept(3SOCKET). The listen() call applies only to sockets of type SOCK_STREAM or SOCK_SEQPACKET.

       The backlog parameter defines the maximum length the queue of pending connections may grow to.

       If a connection request arrives with the queue full, the client will receive an error with an indication of ECONNREFUSED for  AF_UNIX sock-
       ets.  If  the  underlying protocol supports retransmission,  the connection request may be ignored so that retries may succeed. For AF_INET
       and AF_INET6sockets, the TCP will retry the connection. If the  backlog is not cleared by the time the tcp times out, the connect will fail
       with ETIMEDOUT.

RETURN VALUES

       A 0 return value indicates success; -1 indicates an error.

ERRORS

       The call fails if:

       EBADF	     The argument s is not a valid file descriptor.

       ENOTSOCK      The argument s is not a socket.

       EOPNOTSUPP    The socket is not of a type that supports the operation listen().

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

NOTES

       There is currently no backlog limit.
