This isn't anything new, there are plenty of sites out there that show you how to do this. Those sites show you step by step what to do, which is great and all, but I want a script, dammit!
#! /bin/bash if [ $# -ne 5 ] then echo "Usage: register_host.sh <NAME> <DESCRIPTION> <KEYNAME> <USER> <HOST>" exit 1 fi NAME=$1 DESC=$2 KEYNAME=$3 USERNAME=$4 HOST=$5 ssh-keygen -f ~/.ssh/$KEYNAME -C "$KEYNAME" cat ~/.ssh/$KEYNAME.pub | ssh $USERNAME@$HOST 'cat >> ~/.ssh/authorized_keys' echo "" >> ~/.ssh/config echo "# $DESC" >> ~/.ssh/config echo "Host $NAME" >> ~/.ssh/config echo "Hostname $HOST" >> ~/.ssh/config echo "IdentityFile ~/.ssh/$KEYNAME" >> ~/.ssh/config echo "user $USERNAME" >> ~/.ssh/config echo "Port 22" >> ~/.ssh/config
./register_host.sh rbpi "Raspberry Pi" rbpi pi 10.0.1.25
There will be a few prompts that you will need to respond to while it's running, but when it completes, you'll be able to simply type ssh rbpi and automatically connect
It may look sloppy to some people... in my defense, I'm not a bash guy.
