    SYNOPSIS:
How to set the TCP keep alive socket option via ACE in Solaris 10?

    DESCRIPTION:
I know that it's often better to have the application code handle its
own keep-alive mechanism for the TCP socket that it uses, but I just
want to know the correct way to enable the Solaris generic keep-alive
mechanism.
I see that Solaris has an ndd /dev/tcp/tcp_keepalive_timeout parameter
that has a default of 2 hours.  I assume that you have to set either
the SO_KEEPALIVE or TCP_KEEPALIVE option when the socket is
established.

I took a quick look in the "C++ Network Programming Vol 1" book, but
didn't see anything.

  Thanks
