Linux openvpn auto reconnect script

auto-ovpn.sh

#!/bin/bash
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin

### Thanks Xream's Work XD

# if you don't have several vpn servers to select, you can comment following line 
# and use your openvpn config file name to replace "${host}.ovpn" in while loop.

read -p "Select the host: " host

function getStatus () {
	ifconfig | grep $1 && return 1
	return 0
}

while [[ 1 ]]; do
	getStatus tun0
	if [[ $? == 0 ]]; then
		echo "openvpn is not connected!"
		echo "Reconnecting!"
                #Replace your_sudo_password to your real user sudo password.
		echo your_sudo_password | sudo -S openvpn --config /home/user/openvpn/${host}.ovpn
		sleep 6
	fi
	sleep 6
done

You can achieve the same by adding keepalive 10 120 to your conf, as stated in the docs.

where the username should be enterd?

@SajadAbasi, in *.ovpn file you can add entry
auth-user-pass up.txt
and in file up.txt:

your_username
your_password

Can anybody state out the procedure how to do it?

I have this error when execute the script on my/path/directory,

utun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 2000
inet6 fe80::11b6:ff42:907:ed7e%utun0 prefixlen 64 scopeid 0xb
utun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 2000
inet6 fe80::11b6:ff42:907:ed7e%utun0 prefixlen 64 scopeid 0xb
utun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 2000
inet6 fe80::11b6:ff42:907:ed7e%utun0 prefixlen 64 scopeid 0xb

And other issue is not clear of the scripte
#Replace your_sudo_password to your real user sudo password.

Thanks

Finally it is fixed!
This is because of the getStatus command not work on my MBP. I comment it out then everything work.
Add the script directory /path/to/my/myscript.sh into the /usr/home~ .profile and .bash_profile and than logout & login again.

Hey!
I keep getting the error message:
$/home/pi/.VPN/auto-ovpn2.sh: 6: /home/pi/.VPN/auto-ovpn2.sh: Syntax error: "(" unexpected

The script seems to output an error already on the 11th row. What could I be doing wrong? When selecting host on the 9th row, what should I pick btw? Simply "host"?

I worked it out.

For some reason running the script with "sh" ended up in this error while ./ worked just fine. Didn't know there were any differences.

Cheers for a neat script!

I have another question though... Is it possible to skip the step on the 9th line? "Select the host: "?
I'd like for the script to run at boot up. Perhaps there is a nother way to launch it at boot up?
