Python端口扫描单线程版：
#!/usr/bin/env python
#coding:utf8
import socket
ip = ‘www.0x6f.info‘
for port in range(1,1024,1):
sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sk.settimeout(2)
print "正在扫描端口: %d" % port
try:
sk.connect((ip,port))
print ‘Server %s port %d OK‘ % (ip,port)
except Exception:
print ‘Server %s port %d is not connected!‘ % (ip,port)
sk.close()
Python端口扫描多进程版：
#coding:utf8
import socket
import sys
import multiprocessing
import time
def test(port):
ip = ‘www.chlinux.net‘
port = int(port)
print port
sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sk.settimeout(0.5)
print "正在扫描端口: %d" % port
try:
sk.connect((ip,port))
print "Server %s port %d OK" % (ip,port)
except Exception:
print "Server %s port %d is not connected!" % (ip,port)
sk.close()
if __name__ == ‘__main__‘:
pool = multiprocessing.Pool(processes=20)
for port in xrange(1,65535):
port = int(port)
pool.apply_async(test,(port, ))
pool.close()
pool.join()
print "Sub-process(es) done."
