How do I implement wake up on lan (WoL)?

Submitted ⁨⁨1⁩ ⁨year⁩ ago⁩ by ⁨Kidplayer_666@lemm.ee⁩ to ⁨selfhosted@lemmy.world⁩

I’m running an old server at home, an IBM system x3400 m3, rocking two x5675 intel processors.

I currently have windows installed on it and connected to it remotely through Parsec (opened a port on my router). I’ve tried using duckDNS to associate my IP with a domain, and got the service running on my server to automatically refresh the IP.

However, the server doesn’t have the best power consumption, so I’d like to use WoL to remotely turn it on. I’ve enabled it in the BIOS, have checked the drivers to enable it, and tried using TeamViewer to use Wake on Lan, but it doesn’t seem to work.

Any suggestions on how to remotely turn it on? (the server also has KVM, tho I’m not exactly sure what that does)

What I do is using OliveTin behind a reverse proxy (traefik with auth) on a Pi. I then have a button in olivetin that sends WoL commands through local network to turn in my ‘big’ server. You can probably run it without issues on a Pi0.

Alternatively, if you have a VPN to your home network, is using an app on your phone to send WoL commands when connected to the VPN. I have tested with both ‘Magic Packet’ and ‘Net Status’ on iOS through WireGuard.

  I like your funny words magic man. Now more seriously, how could I create a VPN to my home network without having an additional computer to spare? Could I use a router for that? (Currently using the crappy ISP provided one just as a modem and using Google stuff to handle WIFi. To get wired to my server I use one of those Powerline things that is connected to the ISP stuff)

    Yes, your router can likely act as a VPN server, but I would definitely have a hardware firewall if you’re going to be exposing ports to the public internet.

    I run a wireguard service on my Unifi Edgerouter and it works pretty well for that situations. I can also (in theory) send WOL packets from home assistant but i've never tried.

    Some routers can act as a VPN, but I don’t think an ISP provided one can.
    
    I would suggest you get a raspberry pi zero W or equivalent(like orange pi zero) and setup a WireGuard server on that. It’s only like $15.
    
    That way you can vpn to your network and access devices / services without opening any additional ports.

In my experience, you don’t, because it never works.

But the server should have an IPMI that allows power control.

  What’s IPMI, how could I use it remotely? (preferably without an additional PC)

Do the lights on the network card light up when it’s connected but off? I believe you should have blinking lights if the card is on. Might be some kind of power setting in the bios to keep the network card on/off?

I have had hit and miss WoL on some of my machines, one work around is to use a smart plug of some kind to turn the power on/off, and there should be a setting to boot the PC when the power reconnects? May not directly help you, but might also be easier?

  Also, when the server is shut off, it isn’t completly so, the powrrsupply clearly remains on (makes some noise) and some lights in the mother of boards remain on (which lights, what do they mean? I don’t know)

  Yes, that was an option I considered, but I’m first trying to find a solution with the stuff I already have. Unfortunately I cannot check, as I am away from home :| Also, it’s the integrated networking, not a dedicated card

Considering it’s an IBM wol will likely only work on the lan1 port or the imm port.

  That’s very useful information. What is IMM (guessing Integrated Management Module), but what does it allow me to do?

    IMM is IBMs out of band management system if you have worked with HP they call it iLO and Dell calls iDRAC. You can get hardware diagnostics from a webpage when the server is powered off but power is still connected. You can also use the page to power on, reboot and shutdown the system. There is even a virtual console so you can see what the video is outputting without a monitor attached.

A lot of people are saying WOL doesn’t work over the internet, but I’ve got it working.

Basically portforward UDP 9 to your broadcast address (the last possible IP in your subnet), eg. 192.168.1.255. Then send the WOL to your public IP which will then get broadcasted out over your network by your router.

Typing this out, I realised this seems like a horrible security practice, so I’ll probably disable it soon anyway, now that I’ve got multiple servers and a failover VPN.

By default WOL doesn’t work over the internet AFAIK. The wikipedia page mentions it a bit en.wikipedia.org/wiki/Wake-on-LAN#Subnet_directed…

Like others said you may be able to get that going with a VPN or anything VPN-like that allows broadcasts between connected systems. Or if your motherboard supports IPMI / IMM you should be able to connect to the system & perform power functions that way.

In my case my motherboard doesn’t have those sort of management functions so in the end I settled on logging into my router remotely & initiated WOL through there. That could be another option for you if your network router is capable of sending WOL packets to the LAN.

I was using windows desktop machines with teamviewer and anydesk and both could wol without port forwarding. Recently I switched to linux and rustdesk and I couldnt figure out how to do the same. So I got workaround, using upsnap docker container that has simple gui with button to turn on devices over wol. So i login to upsnap, turn on machine and then login with remote control. Still looking for all in one solution. I use wireguard to connect to upsnap (wg port open) but Im using it for other services as well.

Other than bios, I remember I had to enable WOL in windows to make it work, not sure is it different for win server.

  I’m using Windows pro, sorry for not clarifying on the post, just regular windows. I use the server mostly as my personal PC, if I wanted to manage a server, I’d switch to Linux lol. Only reason for Windows is gaming. How would I implement wireguard without an additional PC?

    No way Im afraid, but if your mobo allows WOL you should be able to use it with windows and anydesk or teamviewer. Make sure you enable WOL in windows. Iirc you have to open network adapter properties to enable magic packets. Also bios settings, but you said that you enabled it there
