hey

## assistant

Hey! What can I help you with?

## user

there is an ssh tunnel on my vps rn which you are on i want to keep it open 24/7

## assistant

Let me check what's currently running:

### Tool Call: bash

Input:
```
{
  "command": "ps aux | grep ssh",
  "description": "Check running SSH processes"
}
```

Output:

```

### Tool Call: bash

Input:
```
{
  "command": "systemctl list-units --type=service --state=running | grep -i ssh 2>/dev/null; crontab -l 2>/dev/null",
  "description": "Check systemd services and crontab"
}
```

Output:
```

6 * * * * python3 /root/sandbox/weather_bot.py --cron

```

## assistant

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.

## user

ssh -L 5051:localhost:5051 root@185.228.81.207 this is the command

### Tool Call: bash

Input:
```
{
  "command": "curl -s ifconfig.me",
  "description": "Check this server's public IP"
}
```

Output:
```
185.228.81.207
```

## assistant

That's this VPS's own IP. `ssh -L 5051:localhost:5051 root@185.228.81.207` 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.

## user

yes rn its open in my terminal on a different pc

## assistant

Got it. Two things to make it bulletproof:

**1. Server-side (this VPS)** – set keepalive so the connection doesn't drop:

## assistant

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

**On your local machine (most important)** – use `autossh` which auto-reconnects on drop:
```bash
autossh -M 0 -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -L 5051:localhost:5051 root@185.228.81.207
```

Even better, wrap it in a systemd service on your local machine for true 24/7 uptime:
```ini
[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 root@185.228.81.207

[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

uhm what does that mean

## assistant

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:**
1. On your **local PC** – replace `ssh` with `autossh` (just install it, same command). It auto-reconnects when the tunnel drops.
2. 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:
```bash
autossh -L 5051:localhost:5051 root@185.228.81.207
```

## user

but what if i close my pc

## assistant

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

you

## assistant

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

### Tool Call: bash

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

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

it definetely needs security

## assistant

Let me check what auth options opencode has:

### Tool Call: bash

## assistant

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:
```bash
# 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:
```bash
# 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.

After you authenticate, come back and I'll finish setting up the tunnel.

## user

i have this problem

## assistant

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?

## user

i dont have a domain fix it

## assistant

No domain needed then. I'll switch to **Tailscale** — free, no domain, static private IP, and dead simple:

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

### Tool Call: bash

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 subject to change) (default false)
  --login-server value
    	base URL of control server (default https://controlplane.tailscale.com)
  --netfilter-mode value
    	netfilter mode (one of on, nodivert, off) (default on)
  --operator value
    	Unix username to allow to operate on tailscaled without sudo
  --qr, --qr=false
    	show QR code for login URLs (default false)
  --qr-format value
    	QR code formatting (auto, ascii, large, small) (default auto)
  --report-posture, --report-posture=false
    	allow management plane to gather device posture information (default false)
  --reset, --reset=false
    	reset unspecified settings to their default values (default false)
  --shields-up, --shields-up=false
    	don't allow incoming connections (default false)
  --snat-subnet-routes, --snat-subnet-routes=false
    	source NAT traffic to local routes advertised with --advertise-routes (default true)
  --ssh, --ssh=false
    	run an SSH server, permitting access per tailnet admin's declared policy (default false)
  --stateful-filtering, --stateful-filtering=false
    	apply stateful filtering to forwarded packets (subnet routers, exit nodes, and so on) (default false)
  --timeout value
    	maximum amount of time to wait for tailscaled to enter a Running state; default (0s) blocks forever (default 0s)

```

### Tool Call: bash

Input:
```

Output:
```
Usage of /usr/sbin/tailscaled:
  -bird-socket string
    	path of the bird unix socket

  -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")

Tailscale is connected. VPS's Tailscale IP: **100.67.221.82**

Now I'll rebind opencode to the Tailscale IP so it's only accessible through your private network:

### Tool Call: bash

Input:
```
