How to Install and Use Termius SSH Client on Linux

If you manage servers or network devices, a reliable SSH client is essential. Termius is a modern, cross-platform SSH client with a clean interface and powerful features that make managing connections much easier. Here’s how to install and use Termius on your Linux system.

What is Termius?

Termius is more than just an SSH client. It supports SSH, Mosh, and Telnet, and lets you organize hosts into groups, sync your data across devices, and even save frequently used snippets of code. With its intuitive interface, it’s a great alternative to traditional command-line SSH.

Step 1: Downloading Termius

Termius is available as a .deb package (for Debian/Ubuntu) and as an AppImage (for almost any Linux distribution).

For Ubuntu/Debian

1. Go to the Termius Download Page.
2. Download the .deb package.
3. Open your terminal and navigate to your downloads folder:
   cd ~/Downloads
4. Install the package using dpkg:
   sudo dpkg -i termius*.deb
sudo apt-get install -f # Fix any missing dependencies

For Other Linux Distributions

1. Download the AppImage from the Termius Download Page.
2. Make the file executable:
   chmod +x Termius*.AppImage
3. Run it:
   ./Termius*.AppImage

No installation is needed for AppImage. Just run it as needed.

Step 2: Launching Termius

• On Ubuntu/Debian, find Termius in your applications menu and click to launch.
• If you’re using the AppImage, just run the file from your terminal.

Step 3: Setting Up Your First SSH Connection

1. Click the + New Host button (usually on the left sidebar).
2. Enter your server’s IP address, username, and port (default is 22).
3. Choose your authentication method:
   • Password: Enter your SSH password.
   • Private Key: Upload your private key file or paste it in.
4. Click Save.

You’ll now see your new host listed in Termius.

Step 4: Connecting to a Server

• Double-click your saved host, or right-click and choose Connect.
• The terminal window opens, and you’re in.

Pro Tips

• Grouping Hosts: Organize hosts into folders for easier management.
• Snippets: Save frequent commands or scripts to run on any server with one click.
• Sync Across Devices: Create a free Termius account to sync hosts and settings between your desktop, phone, and tablet.

Conclusion

Termius takes SSH management to the next level, whether you’re handling one server or dozens. Its clean UI and features help you work faster and smarter. Give it a try and see if it streamlines your workflow.
