Watchblob - WatchGuard VPN on Linux
 | 
						|
===================================
 | 
						|
 | 
						|
This tiny helper tool makes it possible to use WatchGuard / Firebox / <<whatever
 | 
						|
they are actually called>> VPNs that use multi-factor authentication on Linux.
 | 
						|
 | 
						|
Rather than using OpenVPN's built-in dynamic challenge/response protocol, WatchGuard
 | 
						|
has opted for a separate implementation negotiating credentials outside of the
 | 
						|
OpenVPN protocol, which makes it impossible to start those connections solely by
 | 
						|
using the `openvpn` CLI and configuration files.
 | 
						|
 | 
						|
What this application does has been reverse-engineered from the "WatchGuard Mobile VPN
 | 
						|
with SSL" application on OS X.
 | 
						|
 | 
						|
I've published a [blog post](https://www.tazj.in/en/1486830338) describing the process
 | 
						|
and what is actually going on in this protocol.
 | 
						|
 | 
						|
## Installation
 | 
						|
 | 
						|
Make sure you have Go installed and `GOPATH` configured, then simply
 | 
						|
`go get github.com/tazjin/watchblob/...`.
 | 
						|
 | 
						|
## Usage
 | 
						|
 | 
						|
Right now the usage is very simple. Make sure you have the correct OpenVPN client
 | 
						|
config ready (this is normally supplied by the WatchGuard UI) simply run:
 | 
						|
 | 
						|
```
 | 
						|
watchblob vpnserver.somedomain.org username p4ssw0rd
 | 
						|
```
 | 
						|
 | 
						|
The server responds with a challenge which is displayed to the user, wait until you
 | 
						|
receive the SMS code or whatever and enter it. `watchblob` then completes the
 | 
						|
credential negotiation and you may proceed to log in with OpenVPN using your username
 | 
						|
and *the OTP token* (**not**  your password) as credentials.
