corrupted debug message #51

Closed greenpau closed 9 years ago

greenpau commented 9 years ago

Receiving the following message:

Jun 15 13:58:28 ip-192-168-16-147 pimd[7785]: 13:58:28.401 RECV    30 bytes PIM v2 Hello              from 10.252.63.0     to 1...2.93.0

The 1...2.93.0 is the IP of the receiving interface (10.252.93.0). This only happens when pimd received a packet via local socket. Potential bug.

Hmm, odd. Thanks for reporting it!

Must be some generic error in parsing the source address. (Little bit busy with vacation/kids and another project atm, but planing some pimd work again soon.)

greenpau commented 9 years ago

kids = priority :-)

I hope this is fixed now. Please reopen this issue otherwise!
