Hi,
I have a home network of 8 computers sharing a masqueraded DSL connection
on a 100 Mbps network. While copying files between my computer (2.4.10 kernel
with a 3c905 Boomerang) and the server (2.4.9 kernel with two 3c905Bs) using
scp or rsync the speed is horrible (over an hour for 40 megs). While copying
files between either of the computers and any of the windows boxes on the
network the speeds are fine. I also get normal speeds while accessing the
internet on this computer with the server as the gateway machine.
I've tried numerous configurations in attempts to solve the problem. I
was recieving the status 82 transmit error on the server so I forced the
3c905B on the server into full-duplex, and while the error message
disappeared the speeds did not improve at all. The relevant diagnostics
follow.
Thanks in advance for any help,
Scott Wehrenberg
