SSH access - ssh-rsa not in PubkeyAcceptedAlgorithms

[RogerCWB]

Hi,

We have a partner that access a remote share with us, but after upgrade to version 13.0 we started to receive this message when they try to access remote with SSH key.

tail /var/log/auth.log
userauth_pubkey: key type ssh-rsa not in PubkeyAcceptedAlgorithms [preauth]

Do you guys know if exist some way to permit ssh-rsa key again?

TrueNAS core v13
Intel Core i5 - 32 GB
6 HD - 4 TB WD

Thanks!

By default, TrueNAS 12 cannot initiate a replication to or from TrueNAS 13 due to an outdated SSH client library.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.

Sorry that's almost an old thread but I think this adds up to the same question :

How come ssh -Q PubkeyAcceptedAlgorithms says ssh-rsa is available but it really isn't ? Is sshd_conf totally bypassed by TrueNAS ?
