### Reinício automático do DNSTT
O DNSTT pode ser reiniciado automaticamente sem reiniciar a VPS e sem derrubar o painel inteiro. No painel, abra **DragonCore → DNSTT Tunnel** e configure:
- **Auto Restart Interval**: intervalo como `30m`, `2h` ou `6h`; use `0s`, `off` ou deixe vazio para desativar.
- **Restart Grace Delay**: pausa antes de reabrir a porta UDP; padrão `2s`.
Também é possível editar diretamente o `config.json`:
```json
"dnstt": {
"domain": "t.example.com",
"udp_listen": "[::]:5300",
"privkey_file": "/opt/sshpanel/dnstt.key",
"auto_restart_interval": "6h",
"auto_restart_grace": "2s"
}
```
### Vários domínios/NS no DNSTT
O DNSTT aceita múltiplos domínios raiz no mesmo listener UDP e com a mesma chave. No painel, abra **DragonCore → DNSTT Tunnel → NS / Root Domains** e coloque um domínio por linha. Isso permite usar um domínio público e outro domínio local da sua rede no mesmo servidor.
Exemplo:
```json
"dnstt": {
"domain": "t.example.com",
"domains": [
"t.example.com",
"t.local.lan"
],
"udp_listen": "[::]:5300",
"privkey_file": "/opt/sshpanel/dnstt.key"
}
```
`domain` continua existindo para compatibilidade. O primeiro item de `domains` é usado como domínio principal.
Para testar com DNS local, aponte o NS/A do domínio local para o IP LAN do servidor DNSTT ou configure seu DNS local para encaminhar essa zona para o IP/porta UDP do DNSTT.
### Reinício automático do proxy e UDPGW
O proxy e o UDPGW também podem ser reiniciados por intervalo. Estes reinícios são **hard restart** para substituir o temporizador em `screen` que reiniciava tudo:
- **Proxy Auto Restart Interval** reinicia os listeners públicos (`listen`, `extra_listen` e TLS forwarders) e fecha as sessões SSH ativas.
- **UDPGW Auto Restart Interval** fecha o listener UDPGW e todos os clientes UDPGW conectados antes de subir novamente.
- Use valores como `6h`, `12h` ou `24h`; `0s`, `off` ou vazio desativa.
- **Restart Grace Delay** define a pausa antes de abrir novamente; padrão `2s`.
Exemplo no `config.json`:
```json
{
"listen": "0.0.0.0:80",
"extra_listen": ["0.0.0.0:8080"],
"proxy_auto_restart_interval": "24h",
"proxy_auto_restart_grace": "2s",
"udpgw": {
"listen": "0.0.0.0:7400",
"auto_restart_interval": "24h",
"auto_restart_grace": "2s"
}
}

### DNSTT auto restart
DNSTT can be restarted automatically without rebooting the VPS and without restarting the whole panel. In the panel, open **DragonCore → DNSTT Tunnel** and configure:
- **Auto Restart Interval**: duration like `30m`, `2h`, or `6h`; use `0s`, `off`, or leave it empty to disable.
- **Restart Grace Delay**: pause before reopening the UDP port; default is `2s`.
You can also edit `config.json` directly:
```json
"dnstt": {
"domain": "t.example.com",
"udp_listen": "[::]:5300",
"privkey_file": "/opt/sshpanel/dnstt.key",
"auto_restart_interval": "6h",
"auto_restart_grace": "2s"
}
```
### Multiple DNSTT NS/root domains
DNSTT can accept multiple root domains on the same UDP listener with the same key. In the panel, open **DragonCore → DNSTT Tunnel → NS / Root Domains** and enter one domain per line. This lets you use a public domain and a local network domain on the same server.
Example:
```json
"dnstt": {
"domain": "t.example.com",
"domains": [
"t.example.com",
"t.local.lan"
],
"udp_listen": "[::]:5300",
"privkey_file": "/opt/sshpanel/dnstt.key"
}
```
`domain` is kept for backward compatibility. The first item in `domains` is mirrored as the primary domain.
For local DNS testing, point the local domain's NS/A record to the DNSTT server LAN IP or configure your local DNS server to forward that zone to the DNSTT UDP IP/port.
### Proxy and UDPGW auto restart
The proxy and UDPGW can also restart by interval. These are **hard restarts**, intended to replace a `screen` timer that restarted everything:
- **Proxy Auto Restart Interval** restarts public listeners (`listen`, `extra_listen`, and TLS forwarders) and closes active SSH sessions.
- **UDPGW Auto Restart Interval** closes the UDPGW listener and all connected UDPGW clients before starting again.
- Use values like `6h`, `12h`, or `24h`; `0s`, `off`, or empty disables it.
- **Restart Grace Delay** controls the pause before reopening; default is `2s`.
Example `config.json`:
```json
{
"listen": "0.0.0.0:80",
"extra_listen": ["0.0.0.0:8080"],
"proxy_auto_restart_interval": "24h",
"proxy_auto_restart_grace": "2s",
"udpgw": {
"listen": "0.0.0.0:7400",
"auto_restart_interval": "24h",
"auto_restart_grace": "2s"
}
}
```

### DNSTT scale guard for high-user servers
The integrated DNSTT service includes overload protection so thousands of DNS tunnel users cannot exhaust RAM or crash the whole panel as easily.
DNSTT config fields:
```json
{
"dnstt": {
"max_sessions": 10000,
"max_streams": 15000,
"pending_responses": 20000,
"stream_buffer": 262144,
"udp_read_buffer": 16777216,
"udp_write_buffer": 16777216,
"log_connections": false
}
}
```
Values can be changed in the admin panel under **DNSTT Tunnel**. Use `0` to keep the safe default. Use `-1` only for `max_sessions` or `max_streams` if you intentionally want no hard limit.
Recommended busy-server values:
- `max_sessions`: `10000`
- `max_streams`: `15000`
- `pending_responses`: `20000`
- `stream_buffer`: `262144`
- `udp_read_buffer`: `16777216`
- `udp_write_buffer`: `16777216`
- `log_connections`: `false`
DNSTT now also recovers panics inside DNSTT goroutines, rejects new sessions/streams when limits are reached, and reports these counters in `/api/dnstt`. The admin panel shows them on the main **Dashboard** when DNSTT is enabled. If `dnstt` is disabled in the config, the dashboard card is hidden completely. `/api/dnstt` also returns an `enabled` flag. The old dashboard quick-action button card was removed:
- `active_sessions`
- `active_streams`
- `sess_rejected`
- `stream_rejected`
- `panic_recovered`
- `rec_dropped`
- `parse_err`
- `ch_len`
For very large DNSTT deployments, raise Linux socket buffer limits too, for example:
```bash
cat >/etc/sysctl.d/99-dragon-dnstt.conf <<'SYSCTL'
net.core.rmem_max=67108864
net.core.wmem_max=67108864
net.core.netdev_max_backlog=250000
net.ipv4.udp_mem=262144 524288 1048576
SYSCTL
sysctl --system
```
### DNSTT built-in local DNS / fake DNS over IPv6
DNSTT can now open an extra internal DNS listener for local testing without a second DNS server.
This listener feeds DNS tunnel packets directly into the same integrated DNSTT session pool and private key.
Example IPv6-only config:
```json
{
"dnstt": {
"domain": "t.example.com",
"domains": ["t.example.com", "t.local.lan"],
"udp_listen": "[::]:5300",
"fake_dns_enabled": true,
"fake_dns_listen": "[2001:db8::1234]:53",
"fake_dns_domain": "t.local.lan",
"fake_dns_workers": 4,
"dns_response_workers": 1,
"privkey_file": "/opt/sshpanel/dnstt.key"
}
}
```
Notes:
- `fake_dns_listen` accepts IPv6 bracket syntax such as `[2001:db8::1234]:53` or `[::]:53`.
- IPv6 listeners are opened with `udp6`, so they do not try to reserve IPv4 port 53. This lets an existing IPv4 master DNS keep using IPv4 port 53 while DNSTT uses a new IPv6 address.
- The built-in local DNS listener only accepts `fake_dns_domain`, for example `t.local.lan`.
- `fake_dns_workers` adds concurrent UDP read/parse workers for the local DNS listener. Use `0` for the automatic default; `4` to `8` is a good starting range for busy servers.
- `dns_response_workers` shards DNS response sending. Keep it at `0` or `1` unless the DNSTT **Queue** grows under load; then test `2` to `4`.
- The normal `udp_listen` listener still accepts the full `domains` list.
- Port 53 may require root privileges or the `CAP_NET_BIND_SERVICE` capability.
- These fields can be changed from the admin panel under **DNSTT Tunnel**.
