```
#### Tester
Website for displaying: [genofire/yaja-tester-viewer](https://github.com/genofire/yaja-tester-viewer/tree/master)

(dirty and based on [Freifunk Meshviewer](https://github.com/ffrgb/meshviewer/))

Demo: [tester.chat.sum7.eu](https://tester.chat.sum7.eu)

```
runs xmpp tester server

Usage:
  yaja daemon tester [flags]

Examples:
yaja daemon tester -c /etc/yaja.conf

Flags:
  -c, --config string   path to configuration file (default "yaja-tester.conf")
  -h, --help            help for tester

```
**Features**
- notification of disconnect by server (domain)
	- manage by bot command `admin (add|del) <JID>` and `admin list`)
- auto accept subscription by every user to every bot
- `ping` to `pong` by every user to every bot (for self check)

**Planned**
- improve chat bot implementation
- improve notification (add my self, not only other by admins)
- add new accounts/server
- other checks, maybe like [running](https://conversations.im/compliance/) - [source-code](https://github.com/iNPUTmice/ComplianceTester)
	- software and version of xmpp servers

**Inspiration by**

*Sorry i did not like Java on my server*
- ServerStatus of iNPUTmice: [running](https://status.conversations.im/) - [source-code](https://github.com/iNPUTmice/ServerStatus)

#### Server
```
runs xmpp server

Usage:
  yaja daemon server [flags]

Examples:
yaja daemon server -c /etc/yaja.conf

Flags:
  -c, --config string   path to configuration file (default "yaja-server.conf")
  -h, --help            help for server
```
