How do I install my SSH public key ~/.ssh/id_rsa.pub onto a remote Linux and UNIX server automatically from Linux workstation or Apple OS X laptop without using scp and/or copy & paste method?

Ssh-keygen -t rsa -b 2048 answer the questions or accept the defaults then provide a passphrase for the private key. Now send the pubic key (idrsa.pub) to the remote host as they request. Put the private key in /.ssh/idrsa for the user that you want to access the remote host. Ensure the perms on the.ssh directory are 700 and /.ssh/idrsa. Universal SSH Key Manager can manage PuTTY keys in addition to OpenSSH and Tectia keys. It works with legacy keys on traditional servers as well as dynamic and keyless elastic environments in the cloud. Any larger organization should ensure they have proper provisioning and termination processes for SSH keys as part of their Identify and Access.

You need to use the ssh-copy-id script that uses ssh to log into a remote machine using a login password. The syntax is as follows:

ssh-copy-id user@server.example.com[donotprint][/donotprint]

OR

ssh-copy-id -i ~/.ssh/id_rsa.pub user@server1.cyberciti.biz

OR

ssh-copy-id -i ~/.ssh/id_dsa.pub user@server1.cyberciti.biz

OR use specific port on remote host such as tcp port # 4242:

ssh-copy-id -i /path/key/file.pub 'user@server.example.com -p 4242'

Install ssh-copy-id on a OS X Unix systems

Step # 1: Create the Keys

Type the following ssh-keygen command to generates, manages and converts authentication keys for your workstation / laptop:
ssh-keygen
Make sure you protect keys with the passphrase.

Step # 2: Install the public key

Install key in a remote server called www-03.nixcraft.in, enter:
ssh-copy-id -i ~/.ssh/id_rsa.pub username@www-03.nixcraft.in

Note: If ssh-copy-id command not found on your system, try the following commands to append/install the public key on remote host:
ssh username@www-03.nixcraft.in 'umask 077; mkdir .ssh'
cat $HOME/.ssh/id_rsa.pub ssh username@www-03.nixcraft.in 'cat >> .ssh/authorized_keys'

Step #3: Use keychain for password less login

OpenSSH offers RSA and DSA authentication to remote systems without supplying a password. Microsoft word starter 2010 key generator. keychain is a special bash script designed to make key-based authentication incredibly convenient and flexible (see how to install keychain script on unix). Add following lines to your ~/.bash_profile or shell login file:

Save and close the file.
