Of course when some enables the SCTP one it should be interesting to clash this against other sub-sys's. The SCTP on can (and is) used by researchers to be able to generate charts and graphs on cwnd algorithms.. and performance in various ways... thats why I thought a spare one would be more appropriate... but I can roll with the flow :-D If I get the scrubber programs in good enough shape I need to commit them into the test directory.... You can generate some really cool charts with it :-D R -- Randall Stewart NSSTG - Cisco Systems Inc. 803-345-0369 803-317-4952 (cell)
