It turned out to be one of the cards was bad in 10MB/s mode. Note that this bad card drug the whole network down to <500kb/s until I found it and eliminated it. The lesson learned from this was that just swapping cards does not always tell you that the cards are okay, it maybe one bad card dragging the setup down :-(. The defective card in my case was not listening to the wire before starting to transmit, this caused excess collisions on the network and everyone suffered. Even very light traffic from this node would cause serious problems for all other nodes, a simple ``ping hostname'' would drive my network peformance down the tubes :-( -- Rod Grimes rgrimes@gndrsh.aac.dev.com
