Feature Request: WOL

[bcm314]

Would be nice to have implemented Wake On LAN.

In first step, maybe an extra button on each server would be ok (or simply always make WOL first and VNC-connection have to be manually retried).

The final step, I would suggest the following, when tapping on a server:

• if no WOL is configured/enabled, behavior as it currently is
• else (if WOL is configured/enabled), make a ping first
• if received echo, behavior as it currently is
• else (no echo) send WOL
• wait n seconds (as server needs different time to boot, this value should be set for each server)
• start VNC conection

masybe:

• to be fastest (make n very low), VNC conection should be retried for maximum m seconds if VNC-server not yet ready.

also: could make pings in the server-list before, to show with green/red button the state of them.

IMO adding an extra button/menu item for servers is sufficient.

• To use WOL, one would enable it in server options and provide target MAC address.
• One configured, an entry will be added in the long-press menu for that server.
• When clicked, AVNC will send the magic packet for that server.

To get feedback about when server finishes booting up, I would suggest using mDNS. AVNC already supports it and shows green indicator when a sever is reachable. On Linux, you can tell Avahi to automatically advertise a particular service on boot-up.

@bcm314 Can you try the following APK: https://github.com/gujjwal00/avnc/actions/runs/9338437912/artifacts/1560192543

You can add MAC address in Advanced server options. Then long-press on the server and send WoL packet.

Hi,

yes, it works very well - tested on two clients and with two different servers.

It's a little bit uncomfortable (using long-tap and many times tapping for reconnect), but I guess it's only the first test, right?

To remember:
maybe an option in the server settings "always send WOL after short tap and do reconnect for x times"

[gujjwal00]

Try this: https://github.com/gujjwal00/avnc/actions/runs/9354967090/artifacts/1563768652
It will automatically send WoL packet before connecting, and use the auto-reconnect feature to retry connection.

Works perfect!!!

v2.5 is available with WoL support.
The UI is slightly updated: You need to first enable the Wake-on-LAN checkbox before entering MAC address.
