[resolved] 9.3->9.10: Unable to SSH to host

[AleksB]

After upgrade from 9.3 to 9.10 I no longer able to ssh to the freenas host. I've troubleshooted this as much as I can, but can't figure out what's wrong. Prior to upgrade everything worked without a problem, but right after upgrade stopped.

Here is my ssh -v:

Code:

$ ssh -v freenas

I can continue to access jails which are running on this host problem free. I have no custom configs for ssh on FreeNas.

Any help would be appreciated.

Any further messages in a ssh -vvv ?

Also post sections in your ssh config file in ~/.ssh/config for:

• Host *
• Host freenas

Just in case you have any weird client configuration.

Than you for hints.

Looks like problem was with my ssh agent on my pc, killing it and re-starting solved my issue.

Oh well - go figure it was problematic. I though about that, as I did't get password prompt for ssh key, but though I already entered and saved into keychain.
