Large file transfer gives error: Corrupted MAC on input Print

Source: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/60764

Symptom

When you transfer a large file by HTTP it will disconnect and give you this error:

Disconnecting: Corrupted MAC on input.

This can also happen on SSH, FTP or other protocols as this is a bug with the kernel driver for the network.

Solution

Turn off "offload check summing" with the following command:

ethtool -K eth0 rx off tx off

Depending on the Ethernet driver in use this may not work as some drivers do not support turning off this feature.
