slow Ethernet

2005-04-19 Thread Robert Storey 
Dear All,

I've noticed that transferring files (using the scp command) between a
laptop and a desktop is very slow when using FreeBSD. The laptop is
running Linux (Debian). The desktop is dual-boot (Debian and FreeBSD).
When I boot FreeBSD and scp files to the laptop, transfer times are very
slow. If I reboot the desktop to Debian and transfer files, transfer
times are at twice as fast. It can't be hardware problems, since the
hardware is identical, it's simply the OS.

So my question(s): first, has anybody else seen this? Secondly, does
anyone know the actual cause? And finally, is there a fix for it?

Any help and suggestions are greatly appreciated.

thanks and regards,
Robert

This is typically because of duplex or speed mismatch between the two
endpoints.  e.g. some less capable NICs autodetect badly, so try
specifying the settings exactly.
