Create and Use the SSH Config File

Enhance your SSH experience by leveraging the SSH config file! This guide walks you through creating the configuration file on Windows and Linux machines, defining aliases for easier server access, and utilizing it for streamlined Git operations.

Create the SSH Config File
- Open Notepad and save the file with the filename config at the path C:\Users\YourUser\.ssh.
- Convert the newly created config text file to a config file:
```
cd c:\users\yourUser\.ssh
copy config.txt config
del config.txt
```

Edit the Config File

Open config using Notepad or Notepad++.

Add the following credentials, then save the file:

Syntax:

Host ANY_NAME_1
    HostName SERVER_IP or SERVER_DOMAIN
    User SERVER_USERNAME
    Port SERVER_PORT
    IdentityFile ~/.ssh/YOUR_PVT_SSH_KEY_NAME
    IdentitiesOnly yes

Example:

Host geek-vps-ubuntu
    HostName 181.219.74.228
    User rajesh
    Port 1037
    IdentityFile ~/.ssh/raj_ed25519
    IdentitiesOnly yes

You can add as many Host entries as needed to manage multiple servers and their respective SSH keys.

Use the Config File
- Now, you can use the Host alias to log in to the remote server via CMD or terminal:
```
ssh HOST
```
  Example:
```
ssh geek-vps-ubuntu
```

Access the Remote Server via SSH
- Syntax: ssh -p PORT USERNAME@HOSTIP
- Example: ssh -p 22 raj@216.32.44.12
- OR
- Syntax: ssh HOST
- Example: ssh geek-vps-ubuntu

Create the SSH Config File

Create the file:
```
touch ~/.ssh/config
```
Edit the config file using nano:
```
nano ~/.ssh/config
```

Add the following credentials, then save the file:

Syntax:

Host ANY_NAME_1
    HostName GITHUB_IP or GITHUB_DOMAIN
    User GITHUB_USERNAME
    IdentityFile ~/.ssh/YOUR_PVT_SSH_KEY_NAME
    IdentitiesOnly yes

Example:

Host react_project
    HostName github.com
    User geekyshow1
    IdentityFile ~/.ssh/react_ed25519
    IdentitiesOnly yes

You can add as many Host entries as needed to manage multiple GitHub repositories and their respective SSH keys.

Use the Config File for Git Operations

Verify Connection:
```
ssh -T git@HOST
```
Example:
```
ssh -T git@react_project
```

Clone Git Repo:

git clone git@HOST:GITHUB_USERNAME/REPO_NAME

Example:

git clone git@react_project:geekyshow1/ecomm.git

Git Pull:
```
git pull
```
