I sent some patches to this list which should make CCID2 behave better. For people out there that want to play with CCID2, I added code which enables user-land applications to track the state of CCID2. Here is a graph I obtained when running CCID2 between two boxes on a 100Mbit network [no delay, just "lan delay"]. http://darkircop.org/vger.png If you are interested in this particular aspect [monitoring CCID2] send me a mail and I'll give you info and tools. CCID2 seems to work in this scenario. It doesn't quite work when you add delay. I will sort that out next. But now I gotta do some other stuff. - : send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
