# pve-net-hang-watchdog |
|
| 2 | ||
| 3 |
`pve-net-hang-watchdog` este un serviciu simplu care urmareste jurnalul kernel pentru hang-uri de NIC si incearca recuperarea uplink-ului prin `ifdown` si `ifup`. |
|
| 4 | ||
| 5 |
## Rol |
|
| 6 | ||
| 7 |
Util pentru noduri Proxmox unde interfata fizica din spatele unui bridge WAN poate intra in stare de hang hardware, iar recovery-ul cel mai pragmatic este ciclarea link-ului. |

|
| 22 |
- wrapper optional pentru uninstall: `/usr/local/sbin/xdev-pve-net-hang-watchdog-uninstall` |
|
| 23 |
- defaults: `/etc/default/xdev-pve-net-hang-watchdog` |
|
| 24 |
- unitate systemd: `/etc/systemd/system/pve-net-hang-watchdog.service` |

## Configurare |
|
| 28 | ||
| 29 |
Parametri suportati prin defaults: |
|
| 30 | ||
| 31 |
- `WATCH_BRIDGE` |
|
| 32 |
- `WATCH_IFACE` |
|
| 33 |
- `COOLDOWN_SECONDS` |
|
| 34 |
- `HANG_PATTERN` |
|
| 35 | ||
| 36 |
Daca `WATCH_IFACE` este gol, scriptul incearca sa descopere automat interfata fizica din `bridge-ports`. |
|
| 37 | ||
| 38 |
## Flux rapid |
|
| 39 | ||
| 40 |
```bash |
|
| 41 |
sudo ./setup.sh --local |
|
| 42 |
sudo systemctl status pve-net-hang-watchdog.service |
|
| 43 |
``` |
|
| 44 | ||
| 45 |
## Operare |
|
| 46 | ||
| 47 |
Loguri: |
|
| 48 | ||
| 49 |
```bash |
|
| 50 |
journalctl -u pve-net-hang-watchdog.service -f |
|
| 51 |
``` |
|
| 52 | ||
| 53 |
Configurare: |
|
| 54 | ||
| 55 |
```bash |

sudo systemctl restart pve-net-hang-watchdog.service |
|
| 58 |
``` |
|
