There are some applications that use SIOCGLIFCONF and/or routing sockets to keep track of the interfaces on the system. These applications often build internal lists of interfaces for their own purposes. Unfortunately, some of those applications have O(N^2) or worse algorithms that iterate over those lists. If you have dozens or hundreds of interfaces, that's probably not a problem. If you have many thousands, you can shoot yourself in the foot. (I don't think this is really a _good_ reason for the hard-coded 8192 limit. It's the only reason I know, though.) -- James Carlson, KISS Network <[EMAIL PROTECTED]> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
