yes, that is what I'm getting.

yes. definitely I'm changing the cable, and if needed, the half-zombie netcard.
that'll leave an error source out, at least.

I'll see for that after I near the 430kb/s...

could some options like TCP_NODELAY and/or IPTOS_LOWDELAY help? saw this in the
smb.conf file, but how to set similar paremeters for ftp and others?
another guess is that the RH server has optimization parameters for a big net
situation (many clients with relatively small throughput each one, and a
relatively high risk of collisions) while I need an optimization for a lan
situation (few clients with a large throughput, and a relatively low risk of
collisions...)
I'll post an update as soon as I get something fixed.
