#!/bin/bash
# Name:           putSSHPubKey.sh
# Purpose:        Adds SSH public Key to remote Host
# Author:         Tabletick
# Date:           2012/11/06
#              
# Explanation: adds the public ssh key to the AUTHORIZED_KEYS file on a remote server
# Works only in this particular configuration to shows that it's possible. _Username_ and Keyfile
# is therefore hardcoded.

	
# Edit this 
HOSTUSER="tabletick"   # SSH user with password access on the remote server
HOSTIDFILE="<keyfile>" # Path to the keyfile to deploy (e.g ~/.ssh/id_rsa.pub)

# Defaults
APPSCP=/usr/bin/scp
APPSSH=/usr/bin/ssh
APPSSHPASS=/usr/bin/sshpass
APPSSHCOPYID=/usr/bin/ssh-copy-id
APPECHO=/bin/echo
