# **Retiolum tinc keys and hosts** ## NixOS usage If you are a flake user: ```nix { inputs = { retiolum.url = "git+https://git.thalheim.io/Mic92/retiolum"; }; outputs = { retiolum, ... }: { # Than include `retiolum.nixosModules.retiolum` nixos module in your nixos configurations # To add the retiolum ssl certificate include `retiolum.nixosModules.ca` }; } ``` First add your key to https://github.com/krebs/stockholm Mic92's stockholm fork will than update this repository itself. ```nix { # lookup the ipv6 address from the generated text file ./hosts networking.retiolum.ipv6 = "42:0:3c46:70c7:8526:2adf:0000:0000"; # optional # networking.retiolum.ipv4 = "10.240.0.0"; } ``` ## VPN Setup 1. Install **tinc** (e.g. Ubuntu : `sudo apt install tinc`, MacOS: `brew install tinc --devel`) 2. Create the appropriate directory and perform the initial tinc startup ``` $ sudo mkdir /etc/tinc/retiolum $ sudo tincd -K -n retiolum $ sudo systemctl enable --now tinc@retiolum ``` 3. Provide the key generated in the previous step along with **{your_name}** (unique name for the machine) to @Mic92. You will get your respective IP addresses in return. 4. Create the tinc-up executable in the **/etc/tinc/retiolum** folder ``` $ echo '#!/usr/bin/env bash curl https://retiolum.thalheim.io/tinc-hosts.tar.bz2 | tar -xjvf - -C /etc/tinc/retiolum/ || true ip link set $INTERFACE up ip addr add "Provided_IPv4_from_Step_3"/12 dev $INTERFACE ip addr add "Provided_IPv6_from_Step_3"/16 dev $INTERFACE' > /etc/tinc/retiolum/tinc-up $ chmod +x /etc/tinc/retiolum/tinc-up ``` 5. Create (if it does not exist) the tinc configuration file ``` $ echo 'DeviceType = tun Interface = tinc.retiolum Name = {your_name_from_Step_3} LocalDiscovery = yes ConnectTo = gum ConnectTo = ni ConnectTo = prism ConnectTo = eve ConnectTo = eva AutoConnect = yes' > /etc/tinc/retiolum/tinc.conf ``` 6. Restart the vpn service ``` $ systemctl restart tinc@retiolum ``` You should retrieve hosts' information after the restart. The hosts folder should appear in /etc/tinc/retiolum The list of the hosts is also available here : https://retiolum.thalheim.io/etc.hosts ## SSH Setup 1. Generate an ssh key-pair or provide an already existing public ssh key to one of the authorised users. 2. One of the authorised users should add/modify the user's information in **/modules/users.nix** (https://github.com/Mic92/doctor-cluster-config) 3. Push the change to the repository 4. Log in to **rose**, pull the update(s) (if it's not done in the machine itelf) 5. Get in **/etc/nixos/** directory and run the script **./update-all.sh** ``` $ cd /etc/nixos $ ./update-all.sh ```
