python bind socket.error: [Errno 13] Permission denied
提问by NELOUNI
I have a python script which gets packets from a remote machine and writes them (os.write(self.tun_fd.fileno(), ''.join(packet))) to a tun interface gr3:
我有一个 python 脚本，它从远程机器获取数据包并将它们 (os.write(self.tun_fd.fileno(), ''.join(packet))) 写入 tun 接口 gr3：
Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:10.0.0.6 P-t-P:10.0.0.8 Mask:255.255.255.255

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:5124 (5.0 KiB) TX bytes:0 (0.0 b)
I would like to receive those packets via a separate pong script as follows:
我想通过一个单独的 pong 脚本接收这些数据包，如下所示：
import threading, os, sys, fcntl, struct, socket
from fcntl import ioctl
from packet import Packet
HOST = '10.0.0.6'
PORT = 111
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(1)
conn, addr = s.accept()
print 'Connected by', addr
while 1:
data = conn.recv(1024)
if not data: break
else: print data
conn.sendall(data)
conn.close()
I got this error :
我收到此错误：
s.bind((HOST, PORT))
File "<string>", line 1, in bind
socket.error: [Errno 13] Permission denied

You can't bind to port numbers lower than 1024 as a unprivileged user.
作为非特权用户，您不能绑定到低于 1024 的端口号。
So you should either:
所以你应该：
- Use a port number larger than 1024 (recommended)
- Or run the script as a privileged user
- 使用大于 1024 的端口号（推荐）
- 或者以特权用户身份运行脚本
Harder, but more secure solution if it's really necessary to accept from 111:
如果确实有必要从 111 接受，则更难但更安全的解决方案：
- Run the as unprivileged on a higher port, and forward port 111 to it externally.
- 在更高的端口上以非特权身份运行，并将端口 111 转发到外部。
