Browser SSH Terminal Web UI

Access a remote shell directly from your browser. The NFLTR dashboard includes a full-featured xterm.js terminal — no local SSH client installation, no key distribution. Click "Connect" on any agent proxying an SSH server.

⚠️ Prerequisite

The target machine must have an SSH server (e.g. sshd) running and listening on the configured port (typically 22). The NFLTR agent proxies SSH traffic — it does not provide SSH itself. You also need valid SSH credentials (username + password or key) on the target machine.

How It Works

The browser connects to the NFLTR server over a WebSocket. The server bridges the WebSocket to the SSH tunnel established by the agent. The agent proxies SSH to the target machine. Full interactive terminal with colors, resize, and scrollback.

📱 Mobile Ready

SSH from your phone or tablet. Touch-friendly terminal with on-screen keyboard support.

How to Enable

On the agent

# Start the agent with SSH port exposed
nfltr tcp 22 --name my-ssh-server

# Or forward to a specific SSH server on the network
nfltr tcp 22 --forward 192.168.1.100:22

From the dashboard

Sign in to your NFLTR dashboard
Find the agent in your Agents list
Click the SSH button next to the agent name
A terminal window opens in your browser

💡 Also works from CLI

Prefer a local terminal? Use nfltr ssh-proxy --name <agent-id> from any machine with the CLI installed. See TCP & SSH Tunneling for details.

Use Cases

Emergency access — Access servers running SSH from any device when you're away from your workstation.
Shared access — Give team members browser-based access to SSH-enabled machines without distributing SSH keys to each member.
Locked-down environments — Access servers from networks that block SSH (port 22) but allow HTTPS.
Mobile ops — Run quick diagnostics from your phone during on-call incidents.
Customer support — Provide temporary shell access to support engineers via session tokens.

Remote shell from any browser

No local SSH client needed — full terminal right in the dashboard. Requires an SSH server on the target machine.
