SCP from / to a ubuntu machine stalling at 2112KB

Tried changing the MTU and setting some parameters in sysctl as suggested in some of the forums. But the issue turned out to be the ethernet adapter auto negotiating the speed to 1000Mbps / full with the switch and for some reason it could not really support those speeds.. Installing ethtool and manually setting the speed to 100Mbps solved the issue.  Instructions from here: http://ubuntuforums.org/showthread.php?t=2170219

temporary fix: sudo ethtool -s eth0 speed 100 duplex full

permanent fix: add this to /etc/rc.local

ethtool -s eth0 speed 100 duplex full
