![]() MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet." (copied from wikipedia) The MAC is a factory-burned-in hardware address that the NI recognizes as "that's me". MAC = "A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. NIC = Network Interface Card as above, but plugs into a slot on the motherboard somehow. It's job is to receive the magic packet and pull the "wake me up now" line on the motherboard. NI = Network Interface typically a chip set intended to receive ethernet, but can be optical fiber or some other versions of networking. This is what many people want to do, but risky and even more of a fancy dance step than WOL Also called WOWLAN, WOWAN, other variants of the acronym. WOW = Wake on Wide Area Net, which is WOL but sent from the wild, wooly internet. ![]() WOL = Wake On LAN, what we're trying to do. The problem is, WOL needs eveything from the functions of the machine sending the WOL message to the entirety of the receiving machine to be working perfectly, and "perfectly" has a very long, very picky definition that is hardware and software dependent.įirst some definitions, because I use acronyms a lot. The data you lose may be your own, and it won't be the fault of FreeNAS. Think carefully about whether you know the things you don't know in enough detail. I fully accept that the data I lose is my own, and I will not blame FreeNAS for my fumbles. ![]() I have a long history with computers, back into the 70s, and have the scars to prove it. Worse, because of your lack of education, you may do this without even knowing the dangers. This is probably dead accurate - if you do lots of shut down and wake cycles on your FreeNAS machine, and are not really skilled at what needs done and not done, you flirt with total loss of your data by your own actions and ignorance. It's intended to be run 24/7 and optimized for doing that.I have been warned that indiscriminate shutdown and wake up endangers your data in myriad ways. Hopefully, other posters can fill you in on the details.FreeNAS is not intended to be woken and shut down on demand. However, this general strategy is sound, and vastly more secure than the one your are proposing. This makes it very difficult for me to give details or directions. Unfortunately, I am on the road, responding to your thread from an Android device. You can even modify a router to can act as a ssh server, although the procedure to replace the original firmware with openwrt or dd-wrt is not trivial. Furthermore, a RPi or similar super-lightweight appliance can act as a very effective ssh server. You must set it up using encrypted keys, then disable password authentication altogether. Your security footprint would then be a tiny fraction of what it would otherwise be with a remote desktop.Īll ssh traffic is encrypted. This type of server means using the command line, but ssh if properly configured is far more secure than any remote desktop app, and magic packets can easily be sent from the command line too. Instead, I would recommend an ssh server. There are Linux equivalents, but I would urge against using any of them. ![]() Remote desktop apps like these are notorious for account hijacking. The biggest security hole in your strategy is Teamviewer. I am not trying to be elitest, really I’m not, but a lot of that risk is a legacy of your Windows mindset. However, you should familiarize yourself with the risks, because your stated strategy is fraught with pitfalls and could easily lead to you getting pwned. What you are asking for is conceptually not difficult. I would greatly appreciate tips and help. Second, I need to know if there is a utility/application for Ubuntu that can send WoL magic packets like there is for windows. Now I want to try installing Ubuntu onto a cheap chromebook and then use Teamviewer to remotely control it and send a WoL magic packet.įirst, I need to know if this is even possible. I considered building a raspberry pi for this but it wouldn't have a battery. I can mirror the screens but they don't support remote input. I have an old Nexus 4 and Nexus 5 that I wanted to use for this, but so far they can't be remote controlled the way I need. I have gotten it to work intermittently a few times but have settled on wanting an always on device that uses very little power and has its own battery that I can remote control via Teamviewer or Chrome Remote Desktop and then send the WoL magic packet over the local network with said device. I have been trying for years to get a working WoL setup for my home network while i'm not home.
