python 端口探测 python查看端口

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。
