Hi,

I'm unable to ping.py example. I tried editing my PATH to include the install directory but its still not working.

mtr-packet-python]# python3 ping.py google.com /bin/sh: mtr-packet: command not found Traceback (most recent call last): File "ping.py", line 37, in loop.run_until_complete(probe_coroutine) File "/usr/lib64/python3.6/asyncio/base_events.py", line 484, in run_until_complete return future.result() File "ping.py", line 13, in probe async with mtrpacket.MtrPacket() as mtr: File "/home/mtr-packet-python/mtrpacket/init.py", line 138, in aenter await self.open() File "/home/mtr-packet-python/mtrpacket/init.py", line 313, in open if not await self.check_support('send-probe'): File "/home/mtr-packet-python/mtrpacket/init.py", line 367, in checksupport (, args) = await self._command('check-support', check_args) File "/home/mtr-packet-python/mtrpacket/init.py", line 275, in _command return await future mtrpacket.ProcessError: failure to communicate with subprocess "mtr-packet" (is it installed and in the PATH?)

Some system info:

I think I figured it out, for future on-lookers:

I was using the "mtr" application from "yum install mtr". But I removed this and did a manual install of mtr from here https://github.com/traviscross/mtr

wget https://www.bitwizard.nl/mtr/files/mtr-0.94.tar.gz tar -xvzf mtr-0.94.tar.gz cd mtr-0.94 ./configure && make export MTR_PACKET=/home/mtr-0.94/mtr-packet

Now it seems to be working:
