More SSH probs ...
Server 1 SSH Version Sun_SSH_1.0
Server 2 OpenSSH_3.8.1p1
Server 3 OpenSSH_3.8p1
I created the rsa keys on server1. Public and private. I copied the id_rsa.pub file to server2 and server3 and appended this to the authorized_keys file in the .ssh directory on both. (All servers using the root user only)
On server 1
I then type ssh user@server2 and I get logged in with no issue and I dont have to provide a password.
However - from server1
I then type ssh user@server3 and I get an error as follows:
Connection closed by 0.0.0.0
Any ideas?

ssh-copy-id
SSH-COPY-ID(1) BSD General Commands Manual SSH-COPY-ID(1)
NAME
ssh-copy-id -- copy public keys to a remote host
SYNOPSIS
ssh-copy-id [-lv] [-i keyfile] [-o option] [-p port] [user@]hostname
DESCRIPTION
The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required).
The following options are available:
-i file
Copy the public key contained in file. This option can be specified multiple times and can be combined with the -l option. If a
private key is specified and a public key is found then the public key will be used.
-l Copy the keys currently held by ssh-agent(1). This is the default if the -i option was not specified.
-o ssh-option
Pass this option directly to ssh(1). This option can be specified multiple times.
-p port
Connect to the specified port on the remote host instead of the default.
-v Pass -v to ssh(1).
The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name.
EXIT STATUS
The ssh-copy-id utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
To send a specific key to multiple hosts:
$ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3
HISTORY
The ssh-copy-id utility was written by Eitan Adler <eadler@FreeBSD.org> as a drop-in replacement for an existing utility included with
OpenSSH.
