  1. mkdir ~.ssh
  2. chmod 750 ~
  3. chmod 700 ~/.ssh
  4. touch ~/.ssh/authorized_keys
  5. chmod 600 ~/.ssh/authorized_keys
  6. edit the ~/.ssh/authorized_keys and paste in the contents of the *.pub file from the local server

Then test to see if you can ssh from the local to the remote server without a password.


Hello,
After I enter those codes to local and remote servers, it asks again root password to establish an ssh connection. In server permit root login is prohibit. Could it be the reason?

Thanks in advance
Boris

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
