Hi! Gregory Nowak 05.06.02: >The hwadr is supposed to be the MAC address, right? Why are ifconfig >and arp reporting different hardware addresses? How do I find out my >nic's real mac address? Arp will tell you hw addresses of other computers in same network. It is used when sendin ethernet frames to other computer; in ethernet there is no ip addresses, only hardware or MAC addresses. YOu can find find than address by ifconfig or grepping 'eth' from dmesg: dmesg | grep eth HTH -- Mr. Ari Moisio, Niittykatu 5, 41160 Tikkakoski, +358-40-5055239 ari.moisio at iki.fi http://www.iki.fi/arimo PGP-keyID: 0x3FAF0F05
