There should be a -n option to arp preventing the reverse lookup. Somebody told about this, but apparently, still nobody implemented it yet. > Is the ARP table not initialised after boot? You'll be surprised that there's no arp table at all. :) The supposed-to-be `arp -an' is basically nothing else than: j@uriah 940% netstat -rn | perl -ane 'print "$F[0] at $F[1]\n" if $F[2] =~ "L"' 192.168.0.1 at 0:a0:24:55:7a:c3 The entire arp information is part of the normal routing table. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
