Phil,

Your suggestion greatly helped us to move in the right direction. We have
completed the loopback module for our product in Solaris 10 and soon
we are shipping the Loopback to our Clients.

As we progressed, we encountered a speedy bumper - the packets going in
between TCP and sockmod does not contain any IP or TCP headers,
we managed to get this TCP endpoint information from
TPI messages going between the TCP provider and the user.

All's well that ends well :) we really appreciate your valuable help and
some very definite suggestions to get us this far. Thanking once again for
everything we would safely assume that, we will continue with this knowledge
sharing practice for mutual benefit.

Regards,
Laxmi

Previously I replied to this mail and said I couldn't think of any easy
supported way to do this. However, in conversation with some colleagues
we were discussing whether it might be possible to do this by pushing a
module above TCP. I don't think this is necesarily an easy approach,
there might well be issues depending on what you actually need and there
would probably be a performance hit but it might be worth investigating.

Phil
