I am browsing linux TCP MIB header code and I see many fields but no explanation on what those fields are.

Some of them are obvious but others are not.

Quoted 7 lines

you can see all of them by typing

/proc/net/netstat

Does anyone know about what these fields contain? Is it documented anywhere?

I did a google but could not find anything.

TCPHPAcks - An ack received in TCP fast path. i.e.
header prediction path. In sequence ack that moves the window. See tcp_ack() in tcp_input.c.

TCPPureAcks - Pure ack recvd (i.e. no data was sent).
This excludes the above category.

I am working on documenting this stuff. Probably a couple of weeks away.

I also suggest posting to [email protected], which is the mailing list targeted to networking developers, or even [email protected], which is the mailing list most networking users post problem reports and questions on. Your chances of reaching a networking person who has time to answer the question are greater :).

thanks,
