Inc > You say the 10BaseT was only a few K/sec. You should see 800K/sec or so for a 10BaseT connection (assuming of course you are going over a local connection to another fast machine). Even on a lowly P90 running Linux I regularly see 1600 K/sec with 100BaseT. So I don't think its a limitation of Linux. With the 10BaseT operating this slowly its likely a bad cable, network card or something.... which would also impact the performance of the 100BaseT. If plugged into a managed hub or switch, check the statistics for bad packets, collisions, etc. You might try another cable, network card, port on hub, etc. ------------------------------------------------------------ David Wojtowicz, Sr. Research Programmer / Systems Manager Department of Atmospheric Sciences Computer Services University of Illinois at Urbana-Champaign email: davidw@xxxxxxxx phone: (217)333-8390 ------------------------------------------------------------
