用Python写了一个简陋的端口扫描脚本，其简单的逻辑如下：
1. python DetectHostPort.py iplist.txt(存放着需要扫描的IP地址列表的文本，每行一个地址)
2. 输入扫描端口、扫描时间和扫描间隔。
3. 输出扫描信息。
下面贴上源码，欢迎拍砖。
#!/usr/bin/env python
import sys
import time
import socket
def getaddresslist(addr):
"""
getaddresslist(addr) -> IP address file
IP address read from the file.
:param addr: IP file
:return: Scan ip address list, or error message.
"""
address = []
try:
with open(addr, "r") as iplist:
line = iplist.readlines()
for item in line:
address.append(item.strip("\n"))
return address
except (IOError, IndexError), e:
return str(e)
def scan(iplist, port=80):
"""
scan() -> getaddresslist()
getaddresslist() function returns the IP address of the list.
:param iplist: getaddresslist() Function return value.
:param port: Need to scan the port.
:return: None
"""
if not isinstance(iplist, list):
sys.exit("Function getaddresslist() return error message: %s" % iplist)
# start_time = time.time()
for addr in iplist:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(1)
host = (addr, int(port))
try:
s.connect(host)
print "Host %s:%s connection success." % (host[0], host[1])
except Exception, e:
print "Host %s:%s connection failure: %s" % (host[0], host[1], e)
s.close()
if __name__ == '__main__':
addrs = sys.argv[1]
ScanPort = input("Enter the scan port: ")
Total = input("Enter the scan time <minutes>: ")
Interval = input("Enter the scanning interval <minutes>: ")
EndTime = time.time() + Total * 60
while time.time() < EndTime:
scan(getaddresslist(addrs), ScanPort)
time.sleep(Interval * 60)
continue
else:
print "\nwhile end."
运行时只能扫描一个端口，但是可以对代码进行修改，扩展为扫描多个端口。
