Try transfers in different directions. Example: root@machineAA$ scp -p root@machineBB:/dev/urandom /tmp/urandom root@machineAA$ scp -p /dev/urandom root@machineBB:/tmp/urandom Also try the same from machineBB: root@machineBB$ scp -p root@machineAA:/dev/urandom /tmp/urandom root@machineBB$ scp -p /dev/urandom root@machineAA:/tmp/urandom Do you see slow LAN transfer speeds when only receiving data vs. sending data? If so, chances are it's a duplex problem, and you should either adjust some settings in ifconfig_fxp0 in rc.conf to try and work around it (try forcing media 100baseTX mediaopt full-duplex rather than using autonegotiate), or try a different switch. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
