Large file transfer gives error: Corrupted MAC on input

Asked By 0 points N/A Posted on -

I have a box running dapper and one running edgy. If I transfer large files from the dapper box to my  edgy box  (i. e. ssh-server on dapper box, client on edgy-box), it gives me the following error message:
[email protected]:~$ scp*.MOV .
[email protected]'s password:
PICT0015.MOV 9% 1248KB 611.2KB/s 00:20 ETA
Disconnecting: Corrupted MAC on input.
lost connection
This can be reliably reproduced.
The problem does not occur if I transfer it by "pushing" (i. e. ssh-client on dapper-box and ssh-server on edgy box).  The problem does also not occur with any other ssh-server.

Large file transfer gives error: Corrupted MAC on input


Researched some and so far this is the best that I can give you yet. When you transfer a large file by Http. It will disconnect and will give you this error: Disconnecting: Corrupted Mac on input. This may very well also happen in SSH, FTP and other protocol as this is a bug with the kernel driver for the network. Nonetheless, I was able to look up a possible means to perhaps solve your issue. I hope you've tried some other methods that you were able to research.

What you can do is this:

Turn off "offload check summing with the following command;

ethtool -k eth0 rx off  tx off

*Note: Depending on the Ethernet driver in use, this may very well not work as some of the drivers do not support turning off this feature.
