Python套接字模块：如何在客户端更改本地端口？

Python套接字模块：如何在客户端更改本地端口？

假设您有一个名为

sock

…的套接字，请使用

socket.bind()

import socketsock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)DESTINATION_ADDR = '1.1.1.1'SOURCE_PORT, DESTINATION_PORT = 31415, 80sock.bind(('0.0.0.0', SOURCE_PORT))sock.connect((DESTINATION_ADDR, DESTINATION_PORT))

现在，我运行

tshark

（text

wireshark

）以查看该界面上的流量…

[mpenning@Bucksnort ~]$ sudo tshark -i eth0 tcp and port 31415Capturing on eth0  0.000000 24.19.161.6 -> 1.1.1.1      TCP 31415 > http [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=4228124209 TSER=0 WS=6 12.000009 24.19.161.6 -> 1.1.1.1      TCP 31415 > http [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=4228127209 TSER=0 WS=6 36.000010 24.19.161.6 -> 1.1.1.1      TCP 31415 > http [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=4228133209 TSER=0 WS=6
