I see the SSH server and active sessions, but no outgoing tunnel. What's the exact SSH command you're running for the tunnel? Or is it a reverse tunnel? Share the command and I'll help set it up as a systemd service so it stays alive 24/7 and auto-restarts.

That's this VPS's own IP. ssh -L 5051:localhost:5051 [email protected] would connect back to itself, which isn't useful as a tunnel.

Do you mean:

You run this from your local machine to the VPS (and want me to help with keepalive settings on the VPS side)?
Or you want the VPS to initiate an outbound tunnel to somewhere else?
Or you actually meant -R (reverse tunnel)?

Let me clarify so I can set it up right.

That clears it up. Here's what I recommend:

On your local machine (most important) – use autossh which auto-reconnects on drop:

autossh -M 0 -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -L 5051:localhost:5051 [email protected]

Even better, wrap it in a systemd service on your local machine for true 24/7 uptime:

[Unit]
Description=SSH tunnel
After=network.target

[Service]
Restart=always
RestartSec=10
ExecStart=/usr/bin/ssh -o ServerAliveInterval=60 -o ServerAliveCountMax=3 -L 5051:localhost:5051 [email protected]

[Install]
WantedBy=multi-user.target

On this VPS side – I can enable keepalive to prevent idle disconnects. Want me to add ClientAliveInterval 60 to sshd_config and reload?

user opencode/deepseek-v4-flash-free 6/5/2026

uhm what does that mean

assistant 17393 tokens · Input 124 · Output 161 6/5/2026

No worries. The short version:

Your terminal → VPS tunnel. If your terminal closes or network blips, the tunnel dies. You need something that keeps it alive and reconnects automatically.

Two simple things:

On your local PC – replace ssh with autossh (just install it, same command). It auto-reconnects when the tunnel drops.
On this VPS – I can tweak a setting so SSH doesn't kill idle connections.

Want me to just set up the VPS side? For the local PC, install autossh and run:

autossh -L 5051:localhost:5051 [email protected]

user opencode/deepseek-v4-flash-free 6/5/2026

but what if i close my pc

assistant 18056 tokens · Input 295 · Output 101 6/5/2026

Then the tunnel can't stay up if your PC is off – that's just how it works.

But wait — ssh -L 5051:localhost:5051 means the service on this VPS only listens on localhost. You're using the tunnel to reach it from your PC. If that's the case, you don't need a tunnel at all — we can just make the service accessible directly.

What's running on port 5051 on this VPS?

user opencode/deepseek-v4-flash-free 6/5/2026

you

assistant 17556 tokens · Input 144 · Output 95 6/5/2026

Ah, I'm on port 5051! Let me check what service this is:

bash — ss -tlnp | grep 5051 completed 0s

Input

{
  "command": "ss -tlnp | grep 5051",
  "description": "Check what's listening on port 5051"
}

Output

LISTEN 0      128        127.0.0.1:5051       0.0.0.0:*    users:(("opencode",pid=740662,fd=17))

assistant 17901 tokens · Input 76 · Output 98 6/5/2026

I'm bound to 127.0.0.1:5051 — that's why you needed the tunnel.

Since your PC can't stay on 24/7, the easiest fix: bind me to 0.0.0.0 so you can reach me directly at http://185.228.81.207:5051.

But that means anyone could try hitting this port. Does opencode need auth, or is this just for you?

user opencode/deepseek-v4-flash-free 6/5/2026

it definetely needs security

opencode doesn't have built-in auth. Here are your best options to make it accessible 24/7 securely without keeping your PC on:

Option A: Tailscale (easiest) – creates a private network between your devices:

# on VPS
curl -fsSL https://tailscale.com/install.sh | sh
tailscale up

Then access me at http://<tailscale-ip>:5051 from any device. No open ports, encrypted, auth required.

Option B: Cloudflare Tunnel – also free, no open ports:

# on VPS
cloudflared tunnel --url http://localhost:5051

Gives you a URL to access from anywhere.

Both can be set up as systemd services to run 24/7. Which sounds better? Tailscale is probably the simplest.

You need a domain on Cloudflare for this. Do you have one, or is that page empty?

If you don't have a domain, there's a simpler option: quick tunnel. It gives you a random trycloudflare.com URL — works instantly, no domain needed. The URL changes on restart though.

If you want a permanent URL, you'll need to add a domain to Cloudflare first. Do you have one?

This VPS doesn't have a TUN device (common in some VPS setups). Let me try Tailscale in userspace mode:

bash — systemctl stop tailscaled && sleep 1 && tailscale up --tun=userspace-networking 2>&1 completed 0s

Input

{
  "command": "systemctl stop tailscaled && sleep 1 && tailscale up --tun=userspace-networking 2>&1",
  "description": "Try Tailscale userspace mode",
  "timeout": 15000
}

Output

flag provided but not defined: -tun
Connect to Tailscale, logging in if needed

USAGE
  tailscale up [flags]

"tailscale up" connects this machine to your Tailscale network,
triggering authentication if necessary.

With no flags, "tailscale up" brings the network online without
changing any settings. (That is, it's the opposite of "tailscale
down").

If flags are specified, the flags must be the complete set of desired
settings. An error is returned if any setting would be changed as a
result of an unspecified flag's default value, unless the --reset flag
is also used. (The flags --auth-key, --force-reauth, and --qr are not
considered settings that need to be re-specified when modifying
settings.)

FLAGS
  --accept-dns, --accept-dns=false
    	accept DNS configuration from the admin panel (default true)
  --accept-risk value
    	accept risk and skip confirmation for risk types: lose-ssh,mac-app-connector,all
  --accept-routes, --accept-routes=false
    	accept routes advertised by other Tailscale nodes (default false)
  --advertise-connector, --advertise-connector=false
    	advertise this node as an app connector (default false)
  --advertise-exit-node, --advertise-exit-node=false
    	offer to be an exit node for internet traffic for the tailnet (default false)
  --advertise-routes value
    	routes to advertise to other nodes (comma-separated, e.g. "10.0.0.0/8,192.168.0.0/24") or empty string to not advertise routes
  --advertise-tags value
    	comma-separated ACL tags to request (e.g. "tag:eng,tag:montreal,tag:ssh"); the "tag:" prefix is optional and added automatically when omitted (e.g. "eng,montreal,ssh")
  --audience value
    	Audience used when requesting an ID token from an identity provider for auth keys via workload identity federation
  --auth-key value
    	node authorization key; if it begins with "file:", then it's a path to a file containing the authkey
  --client-id value
    	Client ID used to generate authkeys via workload identity federation
  --client-secret value
    	Client Secret used to generate authkeys via OAuth; if it begins with "file:", then it's a path to a file containing the secret
  --exit-node value
    	Tailscale exit node (IP, base name, or auto:any) for internet traffic, or empty string to not use an exit node
  --exit-node-allow-lan-access, --exit-node-allow-lan-access=false
    	Allow direct access to the local network when routing traffic via an exit node (default false)
  --force-reauth, --force-reauth=false
    	force reauthentication (WARNING: this may bring down the Tailscale connection and thus should not be done remotely over SSH or RDP) (default false)
  --hostname value
    	hostname to use instead of the one provided by the OS
  --id-token value
    	ID token from the identity provider to exchange with the control server for workload identity federation; if it begins with "file:", then it's a path to a file containing the token
  --json, --json=false
    	output in JSON format (WARNING: format

Input

{
  "command": "/usr/sbin/tailscaled --help 2>&1 | head -20",
  "description": "Check tailscaled options",
  "timeout": 5000

Output

Usage of /usr/sbin/tailscaled:
  -bird-socket string
    	path of the bird unix socket
  -cleanup
    	clean up system state and exit
  -config string
    	path to config file, or 'vm:user-data' to use the VM's user-data (EC2)
  -debug string
    	listen address ([ip]:port) of optional debug server
  -encrypt-state
    	encrypt the state file on disk; when not set encryption will be enabled if supported on this platform; uses TPM on Linux and Windows, on all other platforms this flag is not supported
  -hardware-attestation
    	use hardware-backed keys to bind node identity to this device when supported
    	by the OS and hardware. Uses TPM 2.0 on Linux and Windows; SecureEnclave on
    	macOS and iOS; and Keystore on Android. Only supported for Tailscale nodes that
    	store state on filesystem.
  -no-logs-no-support
    	disable log uploads; this also disables any technical support
  -outbound-http-proxy-listen string
    	optional [ip]:port to run an outbound HTTP proxy (e.g. "localhost:8080")
