Running openvpn without it hanging the terminal

Whilst messing around with HackTheBox, I attempted to connect to the VPN from an Ubuntu VM I have with Google.

The annoying part was that after it ran, it would hang at "Initialization Sequence Completed", and required a second terminal connection to continue. If I Control+C'd, it would kill the VPN connection.

After a bit of searching, I found that I could run it then background it by going

> sudo openvpn Reelix.ovpn &

In which case it would still hang at "Initialization Sequence Completed", but I could Control+C it without it killing it. Close... But the hanging annoyed me.

After a bit more searching, I found that OpenVPN had a --daemon parameter, but going

> sudo openvpn Reelix.ovpn --daemon

Threw up an error

> Options error: I'm trying to parse "Reelix.ovpn" as an --option parameter but I don't see a leading '--'
> Use --help for more information.

After much searching, I eventually discovered the trick!

> sudo openvpn --config Reelix.ovpn --daemon

Success!

To kill the connection, I could either go

> sudo pkill -f "openvpn --config Reelix.ovpn"

Or

> ps aux | grep openvpn
> sudo kill -2 processIdHere

Starcraft 2 AI Battles!

Whilst going through my daily news, I found an article about how an AI Bot in Starcraft 2 managed to beat the hardest native SC2 AI. In my search for the videos of these battles (Which I couldn't find), I managed to find the SC2 API for bots, and with a little more searching - The SC2 AI Ladder.

Browsing their Wiki, I came across a SC2 Bot writted in C#. So, I did what any awesome developer would do - I downloaded it, customized the daylights out of it, and entered it into the AI Ladder (Without expecting to actually get anywhere - Only a few hours work after all). After a few problems with uploading (Which the Site Admin helped me out with on Discord!), I managed to get a working bot onto their ladder.

The initial results amazed me!

Not only was my bot not absolutely terrible - It was winning almost every match it entered! In fact, it had a 78% Win Rate (And a 22% Crash Rate which was destroying my rating...) - And that was just the first version!!! I fixed some crashes, optimized some code, fiddled with the gameplay, and re-entered my Bot - Eager to see how the new changes affected the ratings!

Tiny C# Remote SSH Version Detector

Whilst doing some NetSec stuff, I needed a quick way to get the SSH version of a remote target, so I coded the following.

Demo (No Connection, Open Connection via Netcat, Actual SSH Server, Actual SSH Server on a custom port)

Configuring MPC-HC for easy Anime watching

Whilst watching some Anime recently, I got a bit annoyed that the default language was always set to English, so I had to change the language, and fixed the subtitles every 20 minutes or so which got super annoying.

I eventually found a fix.

Right Click -> Options -> Playback -> Default track preference

Set the number to the "Subtitles" number to the order of the option you prefer at the bottom of the Right Click -> Subtitle Track list, and the "Audio" option to "jpn"
