a simple script when you often have to ssh into the same ip ranges with changing ssh keys (e.g. often reinstalled vms)

README.md

When you often have to SSH into VMs with changing SSH Keys and you dont want to edit your known_hosts everytime ...

Usage:

sshvm.sh 2

Looks for 10.2.3.2 in your known_hosts. Deletes any matching entries. Copies your ssh key. SSHs into the machine.

You need the expect package.

sshvm.sh

#!/bin/bash

IP=10.2.3.$1
SSHUSER=youruser
PW=yourpassword


sed -i "/^$IP/d" /home/$USER/.ssh/known_hosts

expect << EOF
spawn ssh-copy-id $SSHUSER@$IP
expect "Are you sure you want to continue connecting (yes/no)?"
send "yes\n"
expect "password:"
send "$PW\n"
expect eof
EOF

ssh -o "StrictHostKeyChecking no" $SSHUSER@$IP
