My personal OpenConnect and OpenVPN wrapper shell script

vpn - my personal openconnect and vpn wrapper

This is my personal OpenConnect and OpenVPN client wrapper which I use on daily bases because I'm lazy and somehow would like an easy way to check all my connections and configurations.

This script has been build on FreeBSD, so it might only work there :-)

What does it do?

Basically it parses some configuration files provided in your ~/.vpn folder with the following syntax:

service.provider.rc
~~~o~~~ ~~~o~~~
   |       |
   |       o----- Your personal provider name, customer name, or whatever (for example ghostvpn)
   o------------- If it's an openvpn or openconnect service (only these two file types are supported)

Based on the service it run the openconnect command or start a regular FreeBSD openvpn rc-service. For OpenVPN I use the existing rc-services because they work well with multiple configuration files anyway.

How does the files look like?

OpenConnect

It's a regular openconnect configuration file, each line is a long-format configuration option. But there are some additional requirements:

• Each config file should start with # [https://]server[:port][/group] (because this could not be specified in the configuration file by default)
• You should always add the option background (to us the script in a regular way)
• You should add the option pid-file=/var/run/openconnect.YOURPROVIDER.pid to help the script for status information.

Example:

# https://vpn.example.com/SSLVPN
background
passwd-on-stdin
pid-file=/var/run/openconnect.example.pid
user=super.user

Use pass

If the option passwd-on-stdin is used the pass command is executed to receive the password. You need to store the password in the following location:

vpn/service.provider

OpenVPN

They only contains the existing rc-service name, for example:

openvpn_example

Usage

You should simple use the -h option to see all options:

$ vpn -h
