VPN connection helper

This is a command build just for learn a bit of golang that depends on openconnect and any post script you want to execute it before.

About

Bear in mind that this is a first language project just to play a bit with golang and cobra for the cli. Generating more than 4MB binary for something that you would do it with a simple bash script is too much, by the way it works!

On the other hand, thanks to CodelyTV and friendsofgo for introducing me to golang.

Requirements

• Openconnect. This is a simple wrapper to use openconnect, so you might have installed it as well as any additional dependency to connect your VPN
• In addition, you could install vpn-slice and use it as part of your setup with the post script information VPN_POST_SCRIPT

How to run it

1. Download the release binary
2. Make it executable: chmod +x vpn
3. Copy it to the place you want to use it (f.i. /usr/local/bin)
4. Execute it with: vpn connect -h

And follow the instructions:

> vpn connect -h
