Not normally. Your standard NIC does not have sensors for measuring such things and doesn't expose that information to the OS. >I have several cat5 cables that have been twisted, >bent, stepped on, dragged, rolled over, and worse over the years.

You might be able to estimate the quality of a network cable by transferring random data across it from one Debian host to another and measuring the speed. (Or, probably better, the ratio of (packets dropped because of checksum failure) / (total packets sent)). -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
