BlankHi all,
I know this is quite an old kernel version but if any off you can dig his
memory and try to remember it will help...
TCP allows you to open sockets with the XXXX socket option which means if
the connection is quiet (no messages) for at least X time the TCP stack
sends ACK message, every Y secs and gives up after T secs where X,Y,T are
configurable through the proc. When the kernel gives up it should send error
to the socket.
1. The first keep_alive message is sent in an unknown time... No matter what
the proc is configured to we get different time for the first packet.
2. All other keep alives are sent only sometimes... and also in an
unexpected times.
3. I checked and indeed the problem is completely solved in kernel 2.4...
It seems to me like quite a big problem so I figured someone has encountered
it before and maybe published a patch but couldn't find one.
does anyone has any idea ?
thanks,
Ran.
