>We are using a Linux split TCP spoofing proxy that we developed,
>somewhat similar to PEP, and was looking for a mailing list to
>discuss issues like tcp time stamp clocks and their involvement with
>PAWS, and recent additions to 2.6.13; like the congestion control
>algorithms and Dynamic Right-Sizing (DRS).

>We currently have a split proxy and a bidirectional proxy. In
>both cases the proxy Ack's packets from a client. In our split
>case we Echo Time Stamps from the Client and use Time Stamps
>from the Server. Packets to the Server have forwarded copies of
>the echoed time stamps but Time Stamps from the Proxy.

>Our non-split proxy currently doesn't even try to do congestion
>control with time stamps. While upgrading to 2.6.13 with it's new
>congestion control algorithms I was wonder if we should reconsider
>the current paradigm.
