Learn how to get the most out of Linkar, the powerful SSH client for every device.

Linkar Interface

Introduction

Linkar is a modern, cross-platform SSH client designed for speed, security, and ease of use. Whether you're managing a single VPS or an entire data center, Linkar provides the tools you need to stay connected and productive.

Note: Linkar uses end-to-end encryption for all synced data. Your private keys never leave your device unencrypted.

Linux

We provide AppImage, .deb, and .rpm packages for various distributions.

Quick Start

To connect to your first server, click the + Add New Host button on the dashboard.

  1. Enter a name for your connection (e.g., "Production Web").
  2. Input the server IP or hostname.
  3. Specify the port (default is 22).
  4. Choose your authentication method (Password or SSH Key).
  5. Click "Save & Connect".

SSH Basics

Linkar supports all standard SSH features, including interactive shell, command execution, and environment variable passing.

Key Management

You can manage your SSH keys in the Identities tab. Linkar supports RSA, Ed25519, and ECDSA keys.

To add a key, you can either generate a new one within Linkar or import your existing id_rsa files.

Secure Identity Tunneling

Bypass traditional VPNs and connect to isolated networks using zero-trust tunnels. Linkar seamlessly integrates with modern tunnel providers.

Cloudflare Access

Connect directly to Cloudflare Tunnels without exposing your servers to the public internet. Ensure cloudflared is installed on your local machine, select "Cloudflare Access" as the tunnel type when creating a host, and Linkar will automatically proxy the SSH connection through Cloudflare.

Biometric Security

For high-security environments, you can enable Require Biometrics on any host connection. This forces a TouchID, FaceID, or OS-level prompt before the SSH session is allowed to initialize, adding a hardware-backed MFA layer to your infrastructure access.

Live Pair Debugging

Collaborate on terminal sessions in real-time without screen-sharing. Linkar uses low-latency WebSockets to stream terminal data securely.

Host a Session

While connected to a server, click the Share Session button in the top right. Linkar will generate a unique 6-digit Room Code. You can toggle guest permissions between "View Only" (read-only) and "Full Access" (allows guests to type commands).

Join a Session

To join a colleague's session, either click the Join Shared Session icon in the sidebar or enter the Room Code directly in the Welcome Dashboard. You will instantly see the host's terminal output synchronized perfectly.
