所以我正在學習Python和從「暴力蟒」,同時黑客和我遇到了一個問題 這裏是我的代碼:暴力的Python:端口輸入沒有被分隔
import optparse
import socket
from socket import *
from threading import *
screenLock = Semaphore(value = 1)
def connScan(tgtHost, tgtPort):
try:
connSkt = socket(AF_INET, SOCK_STREAM)
connSkt.connect((tgtHost, tgtPort))
connSkt.send('ViolentPython\r\n')
results = connSkt.recv(100)
screenLock.acquire()
print '[+]%d/tcp open' %tgtPort
print '[+] ' + str(results)
except:
screenLock.acquire()
print '[-]%d/tcp closed' %tgtPort
finally:
screenLock.release()
connSkt.close()
def portScan(tgtHost, tgtPorts):
try:
tgtIP = gethostbyname(tgtHost)
except:
print "[-] Cannot resolve '%s': Unknown host" %tgtHost
return
try:
tgtName = gethostbyaddr(tgtIP)
print '\n[+] Scan Results for ' +tgtName[0]
except:
print '\n[+] Scan Results for ' +tgtIP
setdefaulttimeout(10)
for tgtPort in tgtPorts:
print 'Scanning port ' +tgtPort
t = Thread(target=connScan, args=(tgtHost, int(tgtPort)))
t.start()
def main():
parser = optparse.OptionParser('usage %prog ' +\
'-H <target host> -p <target port>')
parser.add_option('-H', dest='tgtHost', type='string', \
help='specify target host')
parser.add_option('-p', dest='tgtPort', type='string', \
help='specify target port[s] seperated by a comma')
(options, args) = parser.parse_args()
tgtHost = options.tgtHost
tgtPorts = str(options.tgtPort).split(', ')
if (tgtHost == None) | (tgtPorts[0] == None):
print parser.usage
exit(0)
portScan(tgtHost, tgtPorts)
if __name__ == '__main__':
main()
運行程序我得到以下錯誤信息:
File "port_scanner.py", line 54, in <module>
main()
File "port_scanner.py", line 52, in main
portScan(tgtHost, tgtPorts)
File "port_scanner.py", line 37, in portScan
t = Thread(target=connScan, args=(tgtHost, int(tgtPort)))
ValueError: invalid literal for int() with base 10: '21,'
任何人都可以請幫忙嗎?我仍然在這個新的,但我的猜測是Python是不運行這個指令分離的不同端口,我輸入:
python port_scanner.py -H 74.207.244.221 -p 21, 22, 80
我針對的IP是scanme.org和掃描製成。謝謝!
我認爲'optparse'將字符串解析爲第一個空格。試試這個:'python port_scanner.py -H 74.207.244.221 -p「21,22,80」' –
你可以用python port_scanner.py -H 74.207.244.221 -p 21,22,80 –
啓動它Daniel說的,但你也需要改變代碼來分割使用'「,」'而不是'「,」'。 'int()'可以跳過空格,所以它應該可以正常工作。 –
