Enable ssh-rsa keys (for connecting to/from old OS to Ubuntu 22.4):

To permit using old RSA keys for OpenSSH 8.8+, add the following lines to your sshd_config:

 HostKeyAlgorithms=ssh-rsa,ssh-rsa-cert-v01@openssh.com
 PubkeyAcceptedAlgorithms=+ssh-rsa,ssh-rsa-cert-v01@openssh.com

Then you need to restart the sshd service:

 sudo systemctl restart sshd
 sudo systemctl status sshd

Rust Crates Local Registry Installation:

For more details on how to use it in your Rust packages: https://book.ktra.dev/index.html
Register the sp-crates registry in your enviroment:
- Run this command. curl command required. replace USER with your desired <UserName>. replace PASSWORD with your desired <Password>. Replace LOCAL_CRATES_IP with the IP for the local sp-crates ktra server: vim ~/.cargo/config.toml
- Add the following in the file:
```
 [registries]
 local-crates = { index = "https://<PATH_TO_GITLAB>/local-crates.git" }
 [net]
 git-fetch-with-cli = true
 
 ### Uncomment this section ONLY if you do not want to import the certificate for the whole system
 #[http]
 #cainfo = "/home/{YOUR_USER_NAME}/<PATH_TO_GITLAB>.crt"
```
- IMPORTANT: Also, you need to download our Gitlab SSL certificate to the location you put on cainfo field above.
- You can import the certificate for the whole system:
```
 sudo apt-get install -y ca-certificates
 sudo cp ~/<CERTIFICATE>.crt /usr/local/share/ca-certificates
 sudo update-ca-certificates
```
Create a new user:
- Run this command. curl command required. Replace USER with your desired <UserName>. Replace PASSWORD with your desired <Password>. Replace LOCAL_CRATES_IP with the IP for the local crates ktra server.
```
 curl -X POST -H 'Content-Type: application/json' -d '{"password":"PASSWORD"}' http://LOCAL_CRATES_IP:8000/ktra/api/v1/new_user/USER
```
- Above command responds and prints a new token like this: {"token":"<TOKEN>"}
- Please copy the <TOKEN>, the printed unreadable token string.
Login to the local cargo registry with cargo command:
- Run this command with the TOKEN that you copied:
```
 cargo login --registry=local-crates <TOKEN>
```
- The local-crates in the command above is the registry name you specified in .cargo/config.toml file.
- It's completed successfully if you get this message: Login token for 'local-crates' saved
Publishing crates:
- Go to your Rust project folder
- Make sure that you specified local-crates as the only repository to publish to by modifying the publish tag in Cargo.toml:
```
[package]
edition = "2021"
exclude = ["tests/"]
name = "my-cool-local-project-rs"
publish = ["local-crates"]
version = "0.10.2"
```
- IMPORTANT: Remember that the first local-crates user that publishes a new crate becomes the owner!
Add more owners to the crate:
- You need to add the rest of sp-crates users as co-owners by executing the following for EVERY user from your project folder:
```
 cargo owner --registry sp-crates --add ktra-secure-auth:<USER> <CRATE_NAME>
```

Rust Alias to pull and update ALL Rust repositories:

Add the following into your ~.bashrc file:
