Title: [SOLVED] ssh can't access to server with key
Post by: gieres on July 08, 2018, 05:58:21 PM

Hi,
I install a new server 9.2 in mode server and gateway. I create only one user, no group, etc.
I can connect to this server as root from LAN (Debian workstation) without keys (with password).
I can't connect with keys.
With the same keys, I can connect to another old kOOZALI server 9.2.
In the two Koozali servers, the only difference beetween the 2 files /etc/ssh/sshd_config is ListenAddress
On the new server, it's the server LAN adress ; on the old, it's 0.0.0.0

Thank you for the attention.

Did you read the wiki?

Did you paste your public key in authorized_keys?

Have you checked the ssh setting in server-manager? The difference in Listen Address is because you probably have sshd set to the default LAN only connections.

Again, read the wiki.

Check:

config show sshd

Yes.

Yes, I have paste first in /root/.ssh/authorized_keys, then in authorized_keys2 (as in my old Koozali).

When connection with password is on, connection work.
When it's forbidden, response is «denied public key» or something equivalent.

Thanks in advance.

Don't use keys2... it is becoming deprecated. You only need it once anyway.

Check your logs and use ssh -v to see what happens.

If the key is correct it should just work.

Hi,
Excuse me, I'm tired.
I write authorized.keys instead of authorized_keys as in the post...

Thanks you ReetP.
