Lightweight network IP scanner with web GUI. Features:
- Send notification when new host is found
- Monitor hosts online/offline history
- Keep a list of all hosts in the network
- Send data to `InfluxDB2` or `Prometheus` to make a `Grafana` dashboard

## Quick start
<details>
<summary>Expand</summary>
Replace `$YOURTIMEZONE` with correct time zone and `$YOURIFACE` with network interface you want to scan. Network mode must be `host`. Set `$DOCKERDATAPATH` for container to save data:
```sh
docker run --name wyl \
-e "IFACES=$YOURIFACE" \
-e "TZ=$YOURTIMEZONE" \
--network="host" \
-v $DOCKERDATAPATH/wyl:/data/WatchYourLAN \
aceberg/watchyourlan
```
Web GUI should be at http://localhost:8840
</details>
## Auth
<details>
<summary>Expand</summary>
**WatchYourLAN** does not have built-in auth option. But you can use it with SSO tools like Authelia, or my simple auth app [ForAuth](https://github.com/aceberg/ForAuth).
Here is an example [docker-compose-auth.yml](https://github.com/aceberg/WatchYourLAN/blob/main/docker-compose-auth.yml).
> :warning: **WARNING!**
> Please, don't forget that WYL needs `host` network mode to work. So, WYL port will be exposed in this setup. You need to limit access to it with firewall or other measures.

## Config
<details>
<summary>Expand</summary>
Configuration can be done through config file, GUI or environment variables. Variable names is `config_v2.yaml` file are the same, but in lowcase.
### Basic config
| Variable | Description | Default |
| -------- | ----------- | ------- |
| TZ | Set your timezone for correct time | |
| HOST | Listen address | 0.0.0.0 |
| PORT | Port for web GUI | 8840 |
| THEME | Any theme name from https://bootswatch.com in lowcase or [additional](https://github.com/aceberg/aceberg-bootswatch-fork) | sand |
| COLOR | Background color: light or dark | dark |
| NODEPATH | Path to local node modules | |
| SHOUTRRR_URL | WatchYourLAN uses [Shoutrrr](https://github.com/nicholas-fedor/shoutrrr) to send notifications. It is already integrated, just needs a correct URL. Examples for Discord, Email, Gotify, Matrix, Ntfy, Pushover, Slack, Telegram, Generic Webhook and etc are [here](https://nicholas-fedor.github.io/shoutrrr/) | |
### Scan settings
| Variable | Description | Default |
| -------- | ----------- | ------- |
| IFACES | Interfaces to scan. Could be one or more, separated by space. See [docs/VLAN_ARP_SCAN.md](https://github.com/aceberg/WatchYourLAN/blob/main/docs/VLAN_ARP_SCAN.md). | |
| TIMEOUT | Time between scans (seconds) | 120 |
| ARP_ARGS | Arguments for `arp-scan`. Enable `debug` log level to see resulting command. (Example: `-r 1`). See [docs/VLAN_ARP_SCAN.md](https://github.com/aceberg/WatchYourLAN/blob/main/docs/VLAN_ARP_SCAN.md). | |
| ARP_STRS ARP_STRS_JOINED | See [docs/VLAN_ARP_SCAN.md](https://github.com/aceberg/WatchYourLAN/blob/main/docs/VLAN_ARP_SCAN.md). | |
| LOG_LEVEL | Log level: `debug`, `info`, `warn` or `error` | info |
| TRIM_HIST | Remove history after (hours) | 48 |
| HIST_IN_DB | DEPRECATED since 2.1.3. Now History is always stored in DB. Use TRIM_HIST to reduce DB size | |
| USE_DB | Either `sqlite` or `postgres` | sqlite |
| PG_CONNECT | Address to connect to PostgreSQL. (Example: `postgres://username:
[email protected]:5432/dbname?sslmode=disable`). Full list of URL parameters [here](https://pkg.go.dev/github.com/lib/pq#hdr-Connection_String_Parameters) | |

## Local network only
<details>
<summary>Expand</summary>
By default, this app pulls themes, icons and fonts from the internet. But, in some cases, it may be useful to have an independent from global network setup. I created a separate [image](https://github.com/aceberg/my-dockerfiles/tree/main/node-bootstrap) with all necessary modules and fonts.
Run with Docker:
```sh
docker run --name node-bootstrap \
-p 8850:8850 \
aceberg/node-bootstrap
```
```sh
docker run --name wyl \
-e "IFACES=$YOURIFACE" \
-e "TZ=$YOURTIMEZONE" \
--network="host" \
-v $DOCKERDATAPATH/wyl:/data/WatchYourLAN \
aceberg/watchyourlan -n "http://$YOUR_IP:8850"
```
Or use [docker-compose](docker-compose.yml)
