tcp_info tcpi_last_ack_recv

Postby fewfindfirst » Tue Jul 30, 2013 10:45 pm

Is it a good idea to check for tcp_info.tcpi_last_ack_recv on tcp client socket, before and after sending tcp message to remote server, and use this information to verify that message is received?
Potential problems can be lost data in tcp buffer or duplication on resending and networks with large round trip time. Am I missing something else?

I have made patch for testing to legacy rsyslog-4.8.0 version using info provided in this links.
