This is the week for strange problems...

I use rsync to copy tinydns data files to backup name servers. This has been working for about a year with no problem. Suddenly, I am getting odd errors:


/usr/local/bin/rsync -az -e 'ssh ' data.cdb [EMAIL PROTECTED]:/usr/ local/etc/tinydns/root/data.cdb
channel 1: open failed: administratively prohibited: open failed

The rsync does work. That is, the file is copied over. So this is actually a warning, I guess.

On the other server, the one the file is being copied TO, the following is printed in /var/log/auth.log

Nov 21 12:43:38 qu sshd[4604]: Address 67.111.0.194 maps to on.example.com, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT! Nov 21 12:43:38 qu sshd[4604]: Accepted publickey for root from 67.111.0.194 port 55777 ssh2

I'm guessing this is some sort of DNS mis-match, but I don't quite grasp what the problem could be.

Again, this did work without error or warning until recently. Something has changed, but not the DNS records.

I'm stumped. Any ideas much appreciated. (I have changed the addresses in the examples above to protect the innocent (me!)
