One downside is, this method can only be applied through a local network. 9 is the most popular port, but it can be 7 in some cases. The “255.255.255.255” is the broadcast address, which means that the message will be sent to all the devices in the same network, and the “:9” is the port number that listens to the wake-on-lan command.

Then, you will need to know the MAC address of the network device which your PC has, simply run this command in your PC (if it is Linux, for other OSes there should be a similar option): Simply turn on the computer, press a special key (in my PC it is F12) to do to BIOS settings and you should be able to find that option. In order to enable Wake on LAN on your PC, first, you need to make sure that your BIOS supports this feature. However, this protocol only works for Ethernet-based network devices, so please take note! There are some ready-made programs (both native and web-based) and command-line interfaces such as wakeonlan cli, Wake on Lan Android. Send a target device in the same Local Area Network (LAN, which can be your home wifi or hotspot) with a special message. Wake on LAN is “a computer networking standard which allows a computer to be turned on or awaken by a network message”.

Connect via VNC server (which is equivalent to Team Viewer, except it is open source and allows you to customize it).

Local Port Forwarding (which allows a device at home to receive a signal from the Internet), and,.

Wake on LAN (which allows turning on a device remotely).

That sounds inefficient isn’t it? What if there is a way to leave your PC turned off when you don’t need, and have the ability to turn it on, remotely, when you require.įortunately, it is possible through a couple of techniques, which are:

One easy way could be leaving your PC to always turned on and, for example, install Team Viewer on it. It would be convenient and also cool if you can have access to your own PC when you are not at home, whether through your phone or your laptop. Not really happy about the last as in itself is at times creating a DoS to legitimate users and truth be said, I was thinking to seek a better replacement.Important: This blog requires the reader to have some knowledge in BIOS settings, network communication (i.e ports, TCP/UDP), and a little bit of scripting skill. Obviously, different needs require different set-ups that need their respective optimization, hence my request to have WOL as an optional settingĪs to how I deal with the remote root login attempts, I rely on hardening of the server and make use of fail2ban. This would save up to 128 hours of power consumption per week (6656 hours per year at 1kw/h) as we only work 40 hours a week. So keeping to this scenario as an example I would need the servers available for 8 hours a day Monday to Friday, then rely on WOL for any remote off hours connections. Taking my scenario as an example, office hours are the same for all users and its only occasionally that we connect remotely past the office hours. There are times of absolutely no traffic even at corporate level.

From a corporate perspective, availability is to reflect the ISP (information security policy - basically ISO 27000, COBIT, etc.) to achieve the CIA (confidentiality, integrity and availability) of data.

One question aside our discussion based on your I am absolutely on the same page as you are with regards to availability for collaboration and web browser clients but this can be reduced from 24/7. But this is only possible if you do not use public links (which might be true for your use-case). How would you deal with this user group? For me they must legitimate on something like a proxy-server, which will trigger the WOL and forward to the nextcloud-server, to meet your security needs. Means you may not only have sync-client-user, but also web-user. You could argue that a client could have this host-role as well, but this would be something totally different to my understanding of the cloud idea.Īnother point to mention is, that most of functionality provided by the apps is only usable via the web interface. And for me this process should not be time driven but event driven. This requires an active host managing and publishing changes. And I want to continue the discussion with you to shape the idea.įor me one scenario (with the possibilities nextcloud has today) “scheduled sync” can not handle is collaborative work on shared files/folders. I really appreciate your Idea about the “scheduled sync” and hibernate/WOL.
