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.
