Tue 27 May 2014 08:06:17 PM UTC, comment #9: From all I can test here and read from the code, a RST sent for an ACK to a LISTEN pcb correctly has seqno == ackno, so the original post is invalid to me. Please convince me of the opposite if I'm wrong.

Tue 19 Jun 2012 07:07:18 PM UTC, comment #2: I don't think an pcap is necessary - it's probably just a straightforward bug in lwIP. |
