MTR数据包：错误 - MTR数据包。进程错误： 无法与子进程通信 "mtr-packet"

Question

当我们尝试运行并使用mtrpacket get below error获取traceroute输出时

import asyncio
import mtrpacket
#  A simple coroutine which will start an mtrpacket session and
#  ping localhost
async def probe():
async with mtrpacket.MtrPacket() as mtr:
return await mtr.probe('10.11.12.13')
#  Use asyncio's event loop to start the coroutine and wait for the probe
loop = asyncio.get_event_loop()
try:
result = loop.run_until_complete(probe())
finally:
loop.close()
#  Print the probe result
print(result)

Error: mtrpacket.ProcessError: failure to communicate with subprocess "mtr-packet"  (is it installed and in the PATH?)
mtr-packet: Failure to open IPv4 sockets: Permission denied
mtr-packet: Failure to open IPv6 sockets: Permission denied

有什么建议吗?

Answer 1

可能是套接字权限，尝试使用sudo访问，可能会成功。

Answer 2

mtr-packet设计为使用原始套接字访问运行。如果使用的是Linux，可以使用功能授予二进制套接字访问权限。在其他类unix操作系统上，包括MacOS，它应该是suid root。

下面的命令将授予它访问原始套接字的权限。

Linux:

sudo chown root $(which mtr-packet)
sudo setcap cap_net_raw+ep $(which mtr-packet)

对于其他操作系统:

sudo chown root $(which mtr-packet)
sudo chmod u+s $(which mtr-packet)
