Hi.
I am using gnutar and ssh-2.0.13 to backup one machine over the
network to another (with a tape drive) and after a certain amount
of data (not sure how much, it does not seem to be consistent)
I'll see the following error on the local machine (without the tape
drive)
Disconnected; MAC error (Message authentication check fails.).
And on the remote machine (with the drive) I'll see the following in
/var/log/messages:
Oct 27 12:39:44 remote sshd[29681]: Remote host disconnected: Message authentication
check fails.
Oct 27 12:39:44 remote sshd[29681]: MAC failed, disconnecting: 'Message authentication
check fails.'
The machines are as follows:
local = Intel P120, SuSE Linux 6.0, ssh-2.0.13 and 1.2.27 installed
remote = Sun Sparc 20, RedHat Linux 5.2, ssh-2.0.13 and 1.2.27 installed.
The command I'm using to backup the files from local to remote is:
tar cvfb - 20 /bin /boot /etc /home /lib /root /sbin /usr /var | ssh remote dd
of=/dev/st0 obs=20b
I've tried using a blocksize of 512 and 1024, but same error, so I lowered it
back to 20.
I did not try implicitly using ssh1, but will try that, see if it helps.
Thanks
Josh
