python检测远程服务器tcp端口的方法

本文实例讲述了python检测远程服务器tcp端口的方法。分享给大家供大家参考。具体如下：

python检测远程服务器tcp端口的代码，这段代码可以用来做服务器监控实用

    #!/usr/bin/env python 
    #coding:utf-8 
    #filename:tcp.py 
    '''

    ''' 
    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'请按照如下格式使用: ./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)

希望本文所述对大家的Python程序设计有所帮助。
