====== Script: Connect to VPN, and then SSH into remote server ======
<WRAP center round alert 60%>Puting passwords in scripts is insecure! Use ssh keys instead.</WRAP>
<WRAP center round important 60%>Assumption: You are using network manager, and have a VPN connection named VPN1 already set up</WRAP>

Create a script called **conn** and make it executable
<code bash| conn>
#!/bin/bash
if [ $1 = 'srv1' ]; then
	nmcli con up id VPN1
	sshpass -p 'remotepassword' ssh remoteuser@192.168.2.20
	nmcli con down id VPN1
fi
</code>
Calling the script with **./conn srv1** will up the VPN interface, and connect to remote server via SSH, and down the interface when SSH exists.

You can move the script to /usr/bin directory to be able to call it from anywhere, and without using **./**

For better (any) security, don't use password in a script, or better yet, use a ssh key pair. Tutorial here [[linux:misc:ssh_key_pairs|Using SSH keys to authenticate users]], and here [[linux:misc:ssh_keys|Setup SSH public/private keys and disabling password login]]
