# VPN Verification

VPN Verification checks VPN deployments after deploy, rebuild, or restart actions and before any success claim. It verifies xray status, VLESS URIs, IP matching, SSH port, firewall, and listening ports.

**Install:**

```bash
npx degit https://github.com/Sergei-thinker/vpn-setup/tree/master/.claude/skills/vpn-verify ~/.claude/skills/vpn-verify
```

## README

# VPN Deployment Verification

Mandatory verification checklist after ANY deployment or change to VPN infrastructure. No completion claims without fresh evidence.

## When to Use

**AUTOMATICALLY** (do not wait for user to ask):
- After running `ssh_exec.py deploy quick-rebuild.sh`
- After running any `deploy-*.sh` script
- After `ssh_exec.py restart`
- Before saying "done", "deployed", "VPN is ready", or any success claim

**On request:**
- User asks "is it working?", "did it deploy correctly?"
- User asks to verify/check the VPN

## The Iron Law

```
NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE
```

If you haven't run `ssh_exec.py status` in THIS message, you cannot claim deployment succeeded.

"Should be working" is not verification. Run the command.

## Verification Checklist

Execute ALL checks. Report results as pass/fail with evidence.

### Check 1: Xray Process Running

**Command:** `python ssh_exec.py status`

| Output | Result |
|--------|--------|
| Shows "xray" with "running" status | PASS |
| Shows "stopped", "failed", or no xray info | FAIL -> `python ssh_exec.py restart`, then re-check |
| SSH connection error | FAIL -> run vpn-troubleshoot |

### Check 2: VLESS URIs Generated

**What to verify:** Deployment script output contained at least one line starting with `vless://`

| Condition | Result |
|-----------|--------|
| 1+ VLESS URIs captured from deploy output | PASS |
| No URIs in output | FAIL -> check deploy logs, may need to re-run |

### Check 3: Server IP Matches Config

**What to verify:** The IP address in the VLESS URI matches `VPN_HOST` in `.env`

**How:** Read `.env`, extract `VPN_HOST`, compare with the IP in captured VLESS URIs.

| Condition | Result |
|-----------|--------|
| IPs match | PASS |
| IPs differ | FAIL -> `.env` may be outdated or URI is from old deployment |

### Check 4: SSH Port Changed

**Command:** Check `VPN_SSH_PORT` in `.env` OR run `python ssh_exec.py exec "grep -E '^Port ' /etc/ssh/sshd_config"`

| Condition | Result |
|-----------|--------|
| SSH port is NOT 22 (typically 49152) | PASS |
| SSH port is still 22 | WARN -> "TSPU can block port 22 to foreign IPs. Consider changing." |

### Check 5: Firewall Active

**Command:** `python ssh_exec.py exec "ufw status | head -1"`

| Output | Result |
|--------|--------|
| "Status: active" | PASS |
| "Status: inactive" or command not found | FAIL -> `python ssh_exec.py exec "ufw --force enable"` |

### Check 6: Inbound Ports Listening

**Command:** `python ssh_exec.py exec "ss -tnlp | grep xray"`

| Output | Result |
|--------|--------|
| Shows ports 443, 8443, 2053 (at least one) | PASS |
| No xray ports listening | FAIL -> restart xray, check config |

## Report Format

After all checks, present a summary:

```
Результаты проверки деплоя:
  1. Xray процесс:     [PASS/FAIL]
  2. VLESS URI:         [PASS/FAIL]
  3. IP совпадает:      [PASS/FAIL]
  4. SSH порт:          [PASS/WARN]
  5. Firewall:          [PASS/FAIL]
  6. Порты слушают:     [PASS/FAIL]
```

If ALL pass: provide user with VLESS URIs and client setup instructions.
If ANY fail: diagnose the failure, do NOT claim success.

## Red Flags — STOP Immediately

You are about to violate this rule if you catch yourself:
- Writing "deployed successfully" without running `ssh_exec.py status` first
- Saying "VPN is ready" based on script exit code alone
- Assuming firewall is active because the script enables it
- Presenting URIs without verifying xray is actually running
- Using words like "should work", "probably deployed", "looks good"

## After Verification Passes

Tell user (in Russian):
1. Present the VLESS URIs clearly
2. Remind: "Import URI into your VPN client"
3. Remind: "Enable TUN mode" (critical)
4. Remind: "Test by opening 2ip.ru — should show VPS country for non-Russian sites"
5. Point to platform-specific setup guide (`client-configs/v2rayn-setup.md` for Windows)
