Python batch scan server port 80 Status, python scan port 80

Python batch scan server port 80 Status, python scan port 80

I wrote a simple Port Scan script in Python. The simple logic is as follows:

1. python DetectHostPort. py iplist.txt (stores the text of the IP address list to be scanned, one address per line)

2. Enter the scan port, scan time, and scan interval.

3. Output scan information.

 

The source code is pasted below. You are welcome to make a brick.

#!/usr/bin/env pythonimport sysimport timeimport socketdef 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."

Only one port can be scanned during running, but the code can be modified to scan multiple ports.
