It is on a 10 mb hup with a couple of other boxes (one professional svr4 and one linux 2.2.10 on intel) The hub is a generic dumb 10mb half duplex only unit. The problem is this, When the iMac talked to either Unix box from MACOS, I would get nearly 100% of the bandwidth of the ethernet on put's and get's. When the iMac talked to either Unix box from linux-ppc (several kernels tested), I would get nearly 100 percent on receive but REALLY slow response on transmit (like about 40k/sec). Watching the lights on the hub, it appears that there is a really big delay restarting transmit after a collision occurs. Perhaps duplex set wrong? Since it works fine in MACOS, I looked over the linux driver and didn't see anything obviously wrong. Has anyone else run into this before? Bob -- Robert E.
