Sure. But the dreadful inefficiencies of ifconfig (which uses /proc) compared to ip (which uses netlink) is just painful. Maybe only people doing embedded work actually care about efficiencies anymore. I haven't checked what the ip command does on bsd, which Debian does also try to support. Maybe there would be problems there. -- Len Sorensen _______________________________________________ lpi-examdev mailing list lpi-examdev@lpi.org http://list.lpi.org/cgi-bin/mailman/listinfo/lpi-examdev
