Python methods for detecting TCP ports on remote servers

The example in this article describes how Python detects TCP ports on remote servers. Share to everyone for your reference. Specific as follows:

Python detects the code of the remote server TCP port, which can be used as a server monitoring utility

#!/usr/bin/env python #coding: utf-8 #filename: tcp.py ' Author:gavingeng date: 2011-12-14 09:35:59  ' Import Socke T import sys normal=0 error=1 timeout=5 def Ping (ip,port,timeout=timeout):   try:     cs=socket.socket (socket.af_ Inet,socket. SOCK_STREAM)     address= (str (IP), int (port))     status = CS.CONNECT_EX (address)     Cs.settimeout (timeout)     #this status is returnback from TCPServer     if status! = NORMAL:       print ERROR     else:       print normal
  
   except Exception, E:     print ERROR     print "error:%s"%e     return error   return NORMAL if __name__== ' __ Main__ ':   If Len (SYS.ARGV) < 3:     print ur ' Please use in the following format:./tcp.py www.jb51.net '     sys.exit (1)   IP = SYS.ARGV[1]   port = sys.argv[2]   try:     timeout = sys.argv[3]   except Indexerror, E:     timeout= TIMEOUT   Ping (ip,port,timeout)
  

Hopefully this article will help you with Python programming.
