SSH tunneling, port forwarding, and remote access patterns. Use when setting up local/remote/dynamic port forwards, configuring jump hosts, managing SSH keys, multiplexing connections, transferring files with scp/rsync, or debugging SSH connection issues.

SSH tunneling, port forwarding, and secure remote access. Covers local/remote/dynamic forwards, jump hosts, ProxyCommand, multiplexing, key management, and connection debugging.
# Forward local port 5432 to remote's localhost:5432
# Use case: access a remote PostgreSQL database as if it were local
ssh -L 5432:localhost:5432 user@remote-server
# Then connect locally:
psql -h localhost -p 5432 -U dbuser mydb
# Forward to a different host accessible from the remote
# Remote server can reach db.internal:5432, but you can't
ssh -L 5432:db.internal:5432 user@remote-server
# Forward multiple ports
ssh -L 5432:db.internal:5432 -L 6379:redis.internal:6379 user@remote-server
# Run in background (no shell)
ssh -fNL 5432:db.internal:5432 user@remote-server
# -f = background after auth
# -N = no remote command
# -L = local forward
# Make your local port 3000 accessible on the remote server's port 8080
ssh -R 8080:localhost:3000 user@remote-server
# On the remote: curl http://localhost:8080 → hits your local :3000
# Expose to all interfaces on the remote (not just localhost)
# Requires GatewayPorts yes in remote sshd_config
ssh -R 0.0.0.0:8080:localhost:3000 user@remote-server
# Background mode
ssh -fNR 8080:localhost:3000 user@remote-server
# Create a SOCKS5 proxy on local port 1080
ssh -D 1080 user@remote-server
# Route browser traffic through the tunnel
# Configure browser proxy: SOCKS5, localhos...

# SSH Tunnel SSH tunneling, port forwarding, and secure remote access. Covers local/remote/dynamic forwards, jump hosts, ProxyCommand, multiplexing, key management, and connection debugging. ## When to Use - Accessing a remote database through a firewall (local port forward) - Exposing a local dev server to a remote machine (remote port forward) - Using a remote server as a SOCKS proxy (dynamic forward) - Connecting through bastion/jump hosts - Managing SSH keys and agent forwarding - Transferring files securely (scp, rsync) - Debugging SSH connection failures ## Port Forwarding ### Local forward (access remote service locally) ```bash # Forward local port 5432 to remote's localhost:5432 # Use case: access a remote PostgreSQL database as if it were local ssh -L 5432:localhost:5432 user@remote-server # Then connect locally: psql -h localhost -p 5432 -U dbuser mydb # Forward to a different host accessible from the remote # Remote server can reach db.internal:5432, but you can't ssh -L 5432:db.internal:5432 user@remote-server # Forward multiple ports ssh -L 5432:db.internal:5432 -L 6379:redis.internal:6379 user@remote-server # Run in background (no shell) ssh -fNL 5432:db.internal:5432 user@remote-server # -f = background after auth # -N = no remote command # -L = local forward ``` ### Remote forward (expose local service remotely) ```bash # Make your local port 3000 accessible on the remote server's port 8080 ssh -R 8080:localhost:3000 user@remote-server # On the remote: curl http://localhost:8080 → hits your local :3000 # Expose to all interfaces on the remote (not just localhost) # Requires GatewayPorts yes in remote sshd_config ssh -R 0.0.0.0:8080:localhost:3000 user@remote-server # Background mode ssh -fNR 8080:localhost:3000 user@remote-server ``` ### Dynamic forward (SOCKS proxy) ```bash # Create a SOCKS5 proxy on local port 1080 ssh -D 1080 user@remote-server # Route browser traffic through the tunnel # Configure browser proxy: SOCKS5, localhos...
