My git server is all I need to setup to actually kill my other server (I’ve been moving from servers on these last 2-3 blog entries), that’s why I’m already doing this entry. I’m basically following git’s guide on setting up a server plus some specific stuff for (btw i use) Arch Linux (Arch Linux Wiki: Git server and Step by step guide on setting up git server in arch linux (pushable)).

Note that this is mostly for personal use, so there’s no user/authentication control other than that of SSH. Also, most if not all commands here are run as root.

Prerequisites

Prerequisites¶

I might get tired of saying this (it’s just copy paste, basically)… but you will need the same prerequisites as before (check my website and mail entries), with the extras:

(Optional, if you want a “front-end”) A CNAME for “git” and (optionally) “www.git”, or some other name for your sub-domains.
An SSL certificate, if you’re following the other entries, add a git.conf and run certbot --nginx to extend the certificate.

Those two lines above will need to be run each time you want to add a new repository to your server (yeah, kinda lame… although there are options to “automate” this, I like it this way).

After that you can already push/pull to your repository. I have my repositories (locally) set up so I can push to more than one remote at the same time (my server, GitHub, GitLab, etc.); to do so, check this gist.

Cgit

Cgit¶

Cgit is a fast web interface for git.

This is optionally since it’s only for the web application.

Install the cgit and fcgiwrap packages:

The entry is going to be long because it’s a tedious process. This is also based on Luke Smith’s script, but adapted to Arch Linux (his script works on debian-based distributions). This entry is mostly so I can record all the notes required while I’m in the process of installing/configuring the mail server on a new VPS of mine; also I’m going to be writing a script that does everything in one go (for Arch Linux), that will be hosted here.

This configuration works for local users (users that appear in /etc/passwd), and does not use any type of SQL Database. And note that most if not all commands executed here are run with root privileges.

Prerequisites

Prerequisites¶

Basically the same as with the website with Nginx and Certbot, with the extras:

You will need a CNAME for “mail” and (optionally) “www.mail”, or whatever you want to call the sub-domains (although the RFC 2181 states that it NEEDS to be an A record, fuck the police).
An SSL certificate. You can use the SSL certificate obtained following my last post using certbot (just create a mail.conf and run certbot --nginx again).
Ports 25, 587 (SMTP), 465 (SMTPS), 143 (IMAP) and 993 (IMAPS) open on the firewall.

+Wrapping up¶
 We should have a working mail server by now. Before continuing check your journal logs (journalctl -xe --unit={unit}, where {unit} could be spamassassin.service for example) to see if there was any error whatsoever and try to debug it, it should be a typo somewhere (the logs are generally really descriptive) because all the settings and steps detailed here just (literally just finished doing everything on a new server as of the writing of this text) worked (((it just werks on my machine))).
 Now, to actually use the mail service: first of all, you need a normal account (don’t use root) that belongs to the mail group (gpasswd -a user group to add a user user to group group) and that has a password.
 Next, to actually login into a mail app/program/whateveryouwanttocallit, you will use the following settings, at least for thunderdbird(I tested in windows default mail app and you don’t need a lot of settings):

   I’ve been wanting to do this entry, but had no time to do it since I also have to set up the VPN service as well to make sure what I’m writing makes sense, today is the day.
 Like with any other of my entries I based my setup on the Arch Wiki, this install script and this profile generator script.
 This will be installed and working alongside the other stuff I’ve wrote about on other posts (see the server tag). All commands here are executes as root unless specified otherwise. Also, this is intended only for IPv4 (it’s not that hard to include IPv6, but meh).
-Prerequisites
+Prerequisites¶
 Pretty simple:
 
 Working server with root access, and with Ufw as the firewall.
 Depending on what port you want to run the VPN on, the default 1194, or as a fallback on 443 (click here for more). I will do mine on port 1194 but it’s just a matter of changing 2 lines of configuration and one Ufw rule.
 
-Create PKI from scratch
+Create PKI from scratch¶
 PKI stands for Public Key Infrastructure and basically it’s required for certificates, private keys and more. This is supposed to work between two servers and one client: a server in charge of creating, signing and verifying the certificates, a server with the OpenVPN service running and the client making the request.
 This is supposed to work something like: 1) a client wants to use the VPN service, so it creates a requests and sends it to the signing server, 2) this server checks the requests and signs the request, returning the certificates to both the VPN service and the client and 3) the client can now connect to the VPN service using the signed certificate which the OpenVPN server knows about. In a nutshell, I’m no expert.
 … but, to be honest, all of this is a hassle and (in my case) I want something simple to use and manage. So I’m gonna do all on one server and then just give away the configuration file for the clients, effectively generating files that anyone can run and will work, meaning that you need to be careful who you give this files (it also comes with a revoking mechanism, so no worries).

 You might notice that I didn’t specify how to actually connect to our server. For that we need to do a few more steps. We actually need a configuration file similar to the server.conf file that we created.
 The real way of doing this would be to run similar steps as the ones with easy-rsa locally, send them to the server, sign them, and retrieve them. Nah, we’ll just create all configuration files on the server as I was mentioning earlier.
 Also, the client configuration file has to match the server one (to some degree), to make this easier you can create a client-common file in /etc/openvpn/server with the following content:

 Since this is just pixel art, the importing settings for textures needs to be adjusted so the sprites don’t look blurry. Go to Project -> Project settings… -> Import defaults and on the drop down select Texture, untick everything and make sure Compress/Mode is set to Lossless.

-Preparing the files
+Preparing the files¶
 If you followed the directory structure I used, then only thing needed is to transform the icon to a native Windows ico format (if exporting to Windows, else ignore this part). For this you need ImageMagick or some other program that can transform png (or whatever file format you used for the icon) to ico. I used [Chocolatey][https://chocolatey.org/] to install imagemagick, then to convert the icon itself used: magick convert icon.png -define icon:auto-resize=256,128,64,48,32,16 icon.ico as detailed in Godot‘s Changing application icon for Windows.
-Exporting
+Exporting¶
 You need to download the templates for exporting as detailed in Godot‘s Exporting projects. Basically you go to Editor -> Manage Export Templates… and download the latest one specific to your Godot version by clicking on “Download and Install”.
 If exporting for Windows then you also need to download rcedit from here. Just place it wherever you want (I put it next to the Godot executable).
 Then go to Project -> Export… and the Window should be empty, add a new template by clicking on “Add…” at the top and then select the template you want. I used HTML5, Windows Desktop and Linux/X11. Really the only thing you need to set is the “Export Path” for each template, which is te location of where the executable will be written to, and in the case of the Windows Desktop template you could also setup stuff like “Company Name”, “Product Name”, “File/Product Version”, etc..

 Similarly with the my FlappyBird clone, I plan to update this to a better state.
-Initial setup
+Initial setup¶
 Again, similar to the FlappyBird clone I developed, I’m using the directory structure I wrote about on Godot project structure with slight modifications to test things out. Also using similar Project settings as those from the FlappyBird clone like the pixel art texture imports, keybindings, layers, etc..
 I’ve also setup GifMaker, with slight modifications as the AssetLib doesn’t install it correctly and contains unnecessry stuff: moved necessary files to the res://addons directory, deleted test scenes and files in general, and copied the license to the res://docs directory. Setting this up was a bit annoying because the tutorial it’s bad (with all due respect). I might do a separate entry just to explain how to set it up, because I couldn’t find it anywhere other than by inspecting some of the code/scenes.I ended up not leaving this enabled in the game as it lagged the game out, but it’s an option I’ll end up researching more.
 This time I’m also going to be using an Event bus singleton (which I’m going to just call Event) as managing signals was pretty annoying on my last project; as well as a Global singleton for essential stuff so I don’t have to do as many cross references between nodes/scenes.
-Assets
+Assets¶
 This time I’ll be creating my own assets in Aseprite, wont be that good, but enough to prototype and get things going.
 Other than that I used few key sprites from vryell: Controller & Keyboard Icons and a font from datagoblin: Monogram.

 This is the most challenging part in my opinion as making all the body parts follow the head in a user defined path it’s kinda hard.

-Basic movement
+Basic movement¶
 The most basic thing is to move the head, this is what we have control of. Create a scene called Head.tscn and setup the basic KinematicBody2D with it’s own Sprite and CollisionShape2D (I used a small circle for the tip of the head), and set the Collision Layer/Mask accordingly, for now just layer = bit 1. And all we need to do, is keep moving the snake forwards and be able to rotate left or right. Created a new script called head.gd attached to the root (KinematicBody2D) and added:

 To move other snake parts by following the snake head the only solution I found was to use the Path2D and PathFollow2D nodes. Path2D basically just handles the curve/path that PathFollow2D will use to move its child node; and I say “child node” in singular… as PathFollow2D can only handle one damn child, all the other ones will have weird transformations and/or rotations. So, the next thing to do is to setup a way to compute (and draw so we can validate) the snake’s path/curve.

 After a while of testing and developing, I noticed that sometimes the head “detaches” from the body when a lot of rotations happen (moving the snake left or right), because of how imprecise the Curve2D is. To do this I just send a signal (snake_rotated) whenever the snake rotates and make a small correction (in generic_segment.gd):

 You can also find the jam entry here.
 Similarly with the my FlappyBird clone, I plan to update this to a better state.
-Initial setup
+Initial setup¶
 Again, similar to the FlappyBird clone I developed, I’m using the directory structure I wrote about on Godot project structure with slight modifications to test things out. Also using similar Project settings as those from the FlappyBird clone like the pixel art texture imports, keybindings, layers, etc..
 I’ve also setup GifMaker, with slight modifications as the AssetLib doesn’t install it correctly and contains unnecessry stuff: moved necessary files to the res://addons directory, deleted test scenes and files in general, and copied the license to the res://docs directory. Setting this up was a bit annoying because the tutorial it’s bad (with all due respect). I might do a separate entry just to explain how to set it up, because I couldn’t find it anywhere other than by inspecting some of the code/scenes.I ended up not leaving this enabled in the game as it lagged the game out, but it’s an option I’ll end up researching more.
 This time I’m also going to be using an Event bus singleton (which I’m going to just call Event) as managing signals was pretty annoying on my last project; as well as a Global singleton for essential stuff so I don’t have to do as many cross references between nodes/scenes.
-Assets
+Assets¶
 This time I’ll be creating my own assets in Aseprite, wont be that good, but enough to prototype and get things going.
 Other than that I used few key sprites from vryell: Controller & Keyboard Icons and a font from datagoblin: Monogram.
-The snake
+The snake¶
 This is the most challenging part in my opinion as making all the body parts follow the head in a user defined path it’s kinda hard. I tried with like 4-5 options and the one I’m detailing here is the only one that worked as I wanted for me. This time the directory structure I’m using is the following:
 
 
 FileSystem - Snake dir structure
 
-Basic movement
+Basic movement¶
 The most basic thing is to move the head, this is what we have control of. Create a scene called Head.tscn and setup the basic KinematicBody2D with it’s own Sprite and CollisionShape2D (I used a small circle for the tip of the head), and set the Collision Layer/Mask accordingly, for now just layer = bit 1. And all we need to do, is keep moving the snake forwards and be able to rotate left or right. Created a new script called head.gd attached to the root (KinematicBody2D) and added:

+Setting up path following¶
 To move other snake parts by following the snake head the only solution I found was to use the Path2D and PathFollow2D nodes. Path2D basically just handles the curve/path that PathFollow2D will use to move its child node; and I say “child node” in singular… as PathFollow2D can only handle one damn child, all the other ones will have weird transformations and/or rotations. So, the next thing to do is to setup a way to compute (and draw so we can validate) the snake’s path/curve.
 Added the signal snake_path_new_point(coordinates) to the Event singleton and then add the following to head.gd:

 At this point the only thing to do is to add the corresponding next body parts and tail of the snake. To do so, we need a PathFollow2D to use the live-generating Path2D, the only caveat is that we need one of these per body part/tail (this took me hours to figure out, thanks documentation).
 Create a new scene called Body.tscn with a PathFollow2D as its root and an Area2D as its child, then just add the necessary Sprite and CollisionShap2D for the Area2D, I’m using layer = bit 2 for its collision. Create a new script called generic_segment.gd with the following code:

+Fix on body segments following head¶
 After a while of testing and developing, I noticed that sometimes the head “detaches” from the body when a lot of rotations happen (moving the snake left or right), because of how imprecise the Curve2D is. To do this I just send a signal (snake_rotated) whenever the snake rotates and make a small correction (in generic_segment.gd):
 func _on_snake_rotated() -> void:

 For now I just decided to setup a simple system to see everything works fine. The idea is to make some kind of generic food node/scene and a “food manager” to spawn them, for now in totally random locations. For this I added the following signals: food_placing_new_food(type), food_placed_new_food(type) and food_eaten(type).

 I got the idea of saving the current stats (points, max body segments, etc.) in a separate Stats class for easier load/save data.

-Preparing the files
+Preparing the files¶
 If you followed the directory structure I used, then only thing needed is to transform the icon to a native Windows ico format (if exporting to Windows, else ignore this part). For this you need ImageMagick or some other program that can transform png (or whatever file format you used for the icon) to ico. I used [Chocolatey][https://chocolatey.org/] to install imagemagick, then to convert the icon itself used: magick convert icon.png -define icon:auto-resize=256,128,64,48,32,16 icon.ico as detailed in Godot‘s Changing application icon for Windows.
-Exporting
+Exporting¶
 You need to download the templates for exporting as detailed in Godot‘s Exporting projects. Basically you go to Editor -> Manage Export Templates… and download the latest one specific to your Godot version by clicking on “Download and Install”.
 If exporting for Windows then you also need to download rcedit from here. Just place it wherever you want (I put it next to the Godot executable).
 Then go to Project -> Export… and the Window should be empty, add a new template by clicking on “Add…” at the top and then select the template you want. I used HTML5, Windows Desktop and Linux/X11. Really the only thing you need to set is the “Export Path” for each template, which is te location of where the executable will be written to, and in the case of the Windows Desktop template you could also setup stuff like “Company Name”, “Product Name”, “File/Product Version”, etc..

+Create PKI from scratch¶
 PKI stands for Public Key Infrastructure and basically it’s required for certificates, private keys and more. This is supposed to work between two servers and one client: a server in charge of creating, signing and verifying the certificates, a server with the OpenVPN service running and the client making the request.
 This is supposed to work something like: 1) a client wants to use the VPN service, so it creates a requests and sends it to the signing server, 2) this server checks the requests and signs the request, returning the certificates to both the VPN service and the client and 3) the client can now connect to the VPN service using the signed certificate which the OpenVPN server knows about. In a nutshell, I’m no expert.
 … but, to be honest, all of this is a hassle and (in my case) I want something simple to use and manage. So I’m gonna do all on one server and then just give away the configuration file for the clients, effectively generating files that anyone can run and will work, meaning that you need to be careful who you give this files (it also comes with a revoking mechanism, so no worries).
