[rdiff-backup-users] "Corrupted MAC on input" error

[Walter Hop]

Hi,

for  the  past  week,  I  seem  to  be running into a consistent error
message  during a backup run on one of the machines: "Corrupted MAC on
input".

This error is not a message of rdiff-backup but seems to be emitted by
the  underlying ssh transport. Has anyone experienced this problem and
found a workaround?

The  client's  configuration is equal to five other backup clients who
don't  have this problem. Could this be due to a large file, or a file
containing some kind of escape sequence?

I have tried the following:
- Changing the versions of ssh/sshd on the client and server;
  I have tried OpenSSH 3.8.1p1 (FreeBSD standard) and OpenSSH 4.2p1
- Changing the login shell of the rdiff user on the server to /bin/sh
  instead of tcsh
- Disabling ssh escape chars by using '-e none' parameter to ssh:
  "--remote-schema '/usr/bin/ssh %s -e none rdiff-backup ..."

Versions:   client   and   server  are  FreeBSD  5.4-RELEASE-p3  using
rdiff-backup from ports rdiff-backup-0.12.7_1.

Kind regards,
Walter Hop
