power_line_adapter-network.adb:63 range check failed

I'm getting the following error:

# pla-util enp6s0 discover

Execution of pla-util terminated by unhandled exception

I looked in Wireshark, and I do see that it sends out an Ethernet broadcast packet with protocol 0x8912, and then my Powerline adapters respond with similar packets. So the crash must be happening at some point after it sends the packet, but before it actually displays the results.

I haven't been able to reproduce this issue. Can you provide screenshots of Wireshark showing the details of the response packets or a packet capture file with the 0x8912 protocol packets?

Here's one I just took. The adapter in question wasn't communicating properly with the others at the time, so I only got the response from that one, but it was still enough to cause the crash.

Here's the command line and output from that test:

$ sudo pla-util enp6s0 discover

Thanks for reporting the issue.

I pushed a fix to the master branch, or if you want to test a binary, you can try this: pla-util.gz

Please let me know whether the fix works for you.

Yep, looks like it works now. Thanks for the fix!
