It means the card sees either a lot of collisions or the cable/terminator itself is interrupted. On my machine I even saw (when the network was *very* congested) the DE422 turn completely deaf. An ifconfig down/up solves this. A surplus ethernet bridge that I used to 'bridge' my own little piece of the network from the evil colliding outside world solved this 8-) So much for a hardware fix for something that looks like a driver problem.. (I know, I should try to find out why this happens) Wilko _ ____________________________________________________________________ | / o / / _ Bulte email: wilko@yedi.iaf.nl - Arnhem, The Netherlands |/|/ / / /( (_) Do, or do not.
