Please be more descriptive about exactly what you copied, from where and to where you put it. And the title of this thread does not correlate with the problem description.

Is the connection lost? Or does it just not work (i.e. the connection is never made)?

Assuming the latter, initially check the permissions on
  • The user's home directory;
  • The .ssh directory; and
  • The authorized_keys file
This should be
  • Not writable to anyone except the owner;
  • 700; and
  • 600
respectively.

Moderator's note: I've moved this thread from the AIX Forum as it's not specifically an AIX question. All the same, I'm not sure if there's a significance in the part regarding "cluster nodes" in relation to SSH. If it's found that there is, please can someone return this to the AIX forum?

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. BSD
February 28, 2014 BSD
