unable to copy ssh ID pve-manager 4.1

[Mn1sh]

Hello,

I am new to proxmox and got stuck in following error.


Three proxmoxVE server setup with each having non standard ssh port. When i try to add second node to cluster (should be same for third node ) , I see the error:

unable to copy ssh ID


Are you bound to use ssh port 22?


There is reference for all three server in /etc/hosts file of each of the servers.

Hi,

Quoting a wiki page I'm currently writing:

You have to edit two files per Node.

• nano /etc/ssh/ssh_config

Here add a new line with:

Port <PORT-NO>

Do not forget to replace <PORT-NO> with your chosen port, replace also the <>.

• nano /etc/ssh/sshd_config

Port <PORT-NO>

Here change the Port line so that it matches the one from ssh_config, both must be the same, as the cluster uses these with no port parameter so the default from sshd (= server) and ssh (= client) must match!

Now restart the ssh service for all nodes:

systemctl restart ssh

And you're done.

To connect now to your node via ssh from outside you need to pass the port as parameter (or change the default port int the ssh client config):

ssh -p <PORT-NO> root@<IP>

We are not bound to port 22, but SSH is needed for the cluster to work, and we use a basic

ssh ..@other-node -- command

connections, so to make those work with a different port you have to edit also the client config of the nodes to match the one you use for the server.
And if you add a new Node then change the port before adding it.
