Hello There Linux specialists,
a have set up a linux server with ssh and enabled port 22 by going in to the /etc/ssh/sshd_config file and changed the PasswordAuthorzed form no to yes.
But when i still try to login from my client computer to the server, the only message i get is this: "Permission denied (Publickey,keyboard-interactive).
does someone know what is going on.
Thanx
Hi, welcome
Did you use the YaST module to setup SSH? If not, make sure you use YaST’s firewall module to open the SSH port.
Let’s get some additional output. Clearly your client seems to be able to
connect (the error is an SSH error) but perhaps something else is not
working properly. The ssh client can give you a lot of debugging output:
ssh -vvv user@server.goes.here
Of course, make sure you are not using ‘root’, or if you are that you also
change ‘PermitRootLogin’ to ‘yes’ (and uncomment it) if it is set to ‘no’.
Better yet, test with a user other than ‘root’ since you s build really
not allow direct SSH access via ‘root’ with a password.

Good luck.

IIRC, you need to restart sshd in order to have changes to the config
take effect - did you restart the daemon?

Hello, and yes i did setup the firewall settings to allow ssh. but it stil give me the same error
Mine is a default ssh configuration. All I did was:
systemctl enable sshd.service
systemctl start sshd.service
I opened the port on the correct interface on the firewall.
kvm:~ # grep 'PasswordAuthentication' /etc/ssh/sshd_config
PasswordAuthentication no
# PasswordAuthentication. Depending on your PAM configuration,
# PAM authentication, then enable this but set PasswordAuthentication
kvm:~ #
From another system I was able to ssh in as root, asccept the fingerprint, and login with a password.
I could do the same as root from the localhost:
kvm:~/.ssh # ssh localhost
The authenticity of host 'localhost (127.0.0.1)' can't be established.
ECDSA key fingerprint is SHA256:jTjTrRnkeChX/euzbVHrJ7xHJ368VmKGToIVbC8oX2M.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.

Have a lot of fun...

My guess is following the debug instructions above will show you that you have a host key issue.
I would change the value back to no and follow these instructions if it is keys:

This is not an Install or Boot issue.
From a query from the same poster in the Networking sub-forum (which was an installation question) this problem is probably with an MS Windows client. We are given no information about the client configuration – it could be something like trying to use a deprecated protocol.
