duplicate connection error
Hello All,
I have one multithreaded server program.Due to fluctuating network, my client is getting disconnected, and after some time i received the new connection from same client, which gets treated as duplicate connection for my server. I have kept my tcp keep alive timer is 10 sec.

Can some one guide me, how can i handle this case? What concept i should use from socket programming for it? I tried shutdown and then close for closing the socket, unfortunately that didn't work.



Thanks,
Mustus

cvsconnect

CVSCONNECT(1)															     CVSCONNECT(1)

NAME

       cvsconnect - CVS connection minimizer

SYNOPSIS

       cvsconnect cvsroot [command-to-run ...]

DESCRIPTION

       CVSconnect enables you to do multiple CVS operations on single network connection.  CVSconnect sets up special environment using
       $CVSRSH/$CVSROOT for the command line CVS client.  In the environment, the command line CVS client reuses a network connection.

       CVSconnect is especially designed to use with CVSsuck.  And CVSconnect (or similar) will be integrated to a future version of CVSsuck.
       However, it is planned that CVSsuck directly connects to a cvs server without cvs command.

EXAMPLES

	cvsconnect $HOME/.cvsroot

BUGS

       o   The global option -z for compression cannot be used.  If you use SSH via ext method, you can use compression by SSH instead.

       o   CVS client must be run at a time.  Running two or more clients at a same time will make a trouble.  (will be fixed in future release.)

       o   Some static variables in a CVS server may confuse you.  It's a CVS bug.  Report it to CVS developer :-).

       o   Command line CVS client must request `Root' first.  Don't mind.  There is no implementation which violates this assumption, however I
	   know.  At least, CVS-1.10 and CVS-1.11 should work.

NOTES

       o   When CVS command is failed, CVSconnect automatically re-run the command with reconnected connection when CVS command is failed.
	   Especially the failure is caused by a long running CVS-1.10 server.	Since CVS-1.10 doesn't close some file descriptors, a long running
	   CVS server will exceed a limit of file descriptors.

       o   /bin/sh should be POSIX sh because this script uses ${parameter#pattern}, etc.  If your /bin/sh is ancient Bourne shell, use ksh or
	   bash.
