python檢測遠程伺服器tcp連接埠的方法_python

本文執行個體講述了python檢測遠程伺服器tcp連接埠的方法。分享給大家供大家參考。具體如下：

python檢測遠程伺服器tcp連接埠的代碼，這段代碼可以用來做伺服器監控實用

#!/usr/bin/env python #coding:utf-8 #filename:tcp.py ''' author: gavingeng date:  2011-12-14 09:35:59 ''' import socket 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'請按照如下格式使用: ./tcp.py www.jb51.net 80'     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)

希望本文所述對大家的Python程式設計有所協助。
