I'm trying to replay a pcap to capture with ros2 bag. However, I get this error

which is weird considering how ifconfig shows that it is working fine

Hi there @CFZeon, I'm not sure what your exact problem is, as I can't reproduce this issue on my PC without more information. So let's try to get some more info out of the Tins API - can you please go to Line 189 of src/sensor.cpp and change that line

FROM:

_tins_sniffer_pointer = std::make_unique<Tins::Sniffer>(eth_device, _sniffer_config);

TO:

  try { 
    _tins_sniffer_pointer = std::make_unique<Tins::Sniffer>(eth_device, _sniffer_config);
  } catch (const std::exception & e) {
    std::cout << "Tins error is: " << e.what() << std::endl;
  }

Re-compile and re-run etc, then post the result back here. You should see something like [ouster_tins_driver-1] Tins error is: SIOCGIFHWADDR: No such device

Hi @MattSYoung the tins error that showed was

Sounds like a permissions error. Are you using a virtual environment such as Docker or WSL by any chance?

Try re-running the launch file with sudo, that might give the Ouster driver the permissions it needs to access the ethernet device.

That did the trick! Thank you so much. It did not occur to me that it was a perms issue.

No worries, glad it solved your problem!
