[SOLVED] Proxmox 3.4: Ssh error between nodes

[anvilcom]

I just created a cluster and added a node. I did have difficulties because the switch didn't not properly support multicasting. I replaced the switch and the node was added successfully.

Now when I ssh from the new node to the original node, I get the following error:

ssh pm1buffer_get_ret: trying to get more bytes 4 than in buffer 0
buffer_get_string_ret: cannot extract length
key_from_blob: can't read key type
key_read: key_from_blob

The login is successful, but I'd like to get ride of the error. I've googled it and found that in most cases, it's an issue with a bad or corrupt known hosts file. I've moved the known_hosts files on both nodes from /root/.ssh/known_hosts to /root/.ssh/known_hosts.bak. I still get the error.

I've also run `pvecm updatecerts`. This also does not solve the problem. I feel it has to be another authorized_keys or authorized_hosts file on the system that is causing the error, but I haven't any idea which file it would be, or if it is another issue altogether.

Any help would be appreciated. Thanks in advance.

I solved the issue. I had 3 entries that had newline after ssh-rsa in /etc/pve/priv/known_hosts. I guess that's why I saw the same error 3 times in a row. I commented them out and voila, it works without error. Then I permanently deleted those 3 entries and it seems to be solved.
