I agree that networking has some difficult problems compared with other areas, but I don't think that's the only problem here. If folks actually want to rely on these scripts, perhaps they ought to be tested regularly, made the subject of integration requirements (so that others modifying the stack are required to update them), and even moved out of /usr/demo. That which isn't tested doesn't work. -- James Carlson 42.703N 71.076W <carls...@workingcode.com> _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
