Replication don´t work anymore

[Janko]

I received the following Error on my Testlab with TrueNAS 13.

Code:

[2022/05/13 03:22:19] INFO     [Thread-23850] [zettarepl.paramiko.replication_task__task_1] Connected (version 2.0, client OpenSSH_8.8-hpn14v15)
[2022/05/13 03:22:19] INFO     [Thread-23850] [zettarepl.paramiko.replication_task__task_1] Authentication (publickey) failed.
[2022/05/13 03:22:19] ERROR    [replication_task__task_1] [zettarepl.replication.run] For task 'task_1' non-recoverable replication error ReplicationError('Authentication failed.')

If i switch back to 12.8, all Replication Tasks works fine.

Read the Release Notes for 13!

By default, TrueNAS 12 cannot initiate a replication to or from TrueNAS 13 due to an outdated SSH client library. Allowing replication to or from TrueNAS 13 to TrueNAS 12 requires allowing ssh.rsa algorithms. See OpenSSH 8.2 Release for security considerations. Log into the TrueNAS 13 system and go to Services->SSH. Add the SSH Auxiliary Parameter: PubkeyAcceptedAlgorithms +ssh-rsa.

Thanks Samuel for the tips,
it actually works from a truenas12 server, but I have a legacy Freenas-11.2-U8 server which can't still replicate to a Truenas13 server.

My truenas13 has IP : 172.20.135.11

from Freenas-11.2-U8 I can ssh -i /data/ssh/replication root@172.20.135.11 with no problems and without giving password, but when I add a replication task, there is an error on web-UI and I get this message from /var/log/debug.log (on freenas-11.2-UI server) :

Any idea ?
Thanks in advance for your help

First, please don't necro old threads. Second, your error indicates a problem with the SSH connection corresponding to this replication task. Make sure to use a non-ssh-rsa host key.

ok, my mistake was not having copied my freenas public replication key to truenas13 server (it was working from the console bc I was ssh connected to my freenas using ForwardAgent).
Then now replication task works from 11.2 to 13.1 server. (Note that I am still using an ssh-rsa host key bc I have applied your previous tips "ssh auxliary parameters" on the truenas13 server).
Many thanks !
