How to RESET the client connection socket?

How to RESET the client connection socket?

[Srinivas Chinta]

Hi,

I have a server, and some clients connected to it. How
do i RESET a client connection socket ? Are there any
APIs to do this? or any socket options available?

Any help on this regard is greatly appreciated.

Thanks,

Srini

IIRC you can do that with shutdown(2).

Thanks a lot for clearing my problem.
By the way, is shutdown(2) something similar to
setting socket linger options ?
And, this shutdown(2) send any RESET error something
back to client? or, client will be able to know that
the server has RESET the connection?

Thanks,
Srini

Just try it:) You don't even need to modify your code for that. Simply
start your application within a debugger and call the shutdown function
by hand. While doing so, run a tcpdump to see what's happening.

And for the SO_LINGER option, right, there's some interaction with
close() and shutdown(). See socket(7).

Oh, for in-depth exploration of socket programming, see if you can
afford W. Richard Steven's books (_Unix Network Programming Vol1+Vol2_
for the practical part, _TCP/IP Illustrated Vol1/2/3_ for the theory).
They're really worth the money.
