所以我试图一遍又一遍地向我的VM发送多个数据包,但经过一次尝试后,我收到了错误:
Traceback (most recent call last):
File "SMB_Test2.py", line 157, in <module>
s.sendall(SMB_COM_NEGOTIATE)
File "C:\Python27\Lib\socket.py", line 228, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 10054] An existing connection was forcibly closed by the remote host
我认为是由于重复的错误数据被发送(故意),但我想知道是否以及如何解决这个问题。我基本上希望多次重复发送SMB_COM_NEGOTIATE。提前致谢。
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((addr, port))
s.settimeout(2)
print '[*] Connected to "%s:%d".' % (addr, port)
s.sendall(SMB_COM_NEGOTIATE)
a = 0
while a != 50000:
print a
a = a + 1
s.sendall(SMB_COM_NEGOTIATE)
print '[*] Sent to "%s:%d".' % (addr, port)
编辑(关闭Jame的建议) - 仍然跳到错误:
a = 0
try:
print "The value of 'a' is %r." % a
s.connect((addr, port))
print '[*] Connected to "%s:%d".' % (addr, port)
while a != 50000:
a = a + 1
s.sendall(SMB_COM_NEGOTIATE)
print '[*] Sent to "%s:%d".' % (addr, port)
print "The value 'a' is %r." % a
except:
print "[-] An error occured!!!"
s.close()
exit()
输出:
The value of 'a' is 0.
[*] Connected to "192.168.xxx.xxx:xxx".
[*] Sent to "192.168.xxx.xxx:xxx".
The value 'a' is 1.
[-] An error occured!!!
也试过这个(几乎相同):
a = 0
print "The value of 'a' is %r." % a
s.connect((addr, port))
print '[*] Connected to "%s:%d".' % (addr, port)
def ok():
try:
while a != 50000:
a = a + 1
s.sendall(SMB_COM_NEGOTIATE)
print '[*] Sent to "%s:%d".' % (addr, port)
print "The value 'a' is %r." % a
except:
print "[-] An error occured!!!"
sleep(0)
s.close()
哪个有输出(甚至没有发送任何内容):
The value of 'a' is 0.
[*] Connected to "192.168.xxx.xxx:xxx".
[-] An error occurred!!!
答案 0 :(得分:0)
这是一段代码片段来说明我的评论。
