All I say is that one can get his flows as complicated as he wants... For the trivial features you support in the console there is no complicated equivalent flow in osmsh. For sophisticated requirements you will eventually end up re-writing osmsh. I think there is a place for a safer console. Perhaps there are levels of access privileges where some can do RO things and others have RW access. How would this privilege right be granted? Based on user and/or perhaps group. I do not understand how the permission to write flow through the console is going to be administered. The OpenSM user manual provides extensive description of it, including some programming examples.

No - but if needed we can do that. I do not see why we need to invent yet another way to do these things. Instead I would recommend including osm Tcl extension in the gen2 trunk and put it to work. -- Hal ___ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
