General

  • ssh error "Disconnecting: Corrupted MAC on input.". Python guis will crash with this error from time to time if they are on ssh (i.e. not user is ssh-ing to wolverine). FB tried debugging using ssh -vvv but was unsucessful. Seems to be hardware+kernel related and require changes with ethtool, see https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.17/+bug/60764 . Currently testing if this solution ( ethtool -K eth0 rx off tx off ) works. If yes, then we can add this as a script to /etc/network/if-up.d/.
