15:46 <Armbian-Discord> <R​enegade> Hello. I have a remote armbian host (RPi) and it is very old (Jessie 8.1). I cannot upgrade it any more and I need to install wireguard onto it. I can only ssh into the host. Is it somehow possible to have just wireguard installed into that install or is it not possible at all? I cannot risk in upgrading-in-live because I could loose the connection. Its located physically very distant to me so a connection loss

15:46 <Armbian-Discord> would be a pain in the ass. Any clues how to get wireguard installed ?

15:49 <stipa> maybe you could be able to start it as a service and spare the rest of the system but see it's something related to networking so it could be tricky since you need to poke at the network system

15:50 <stipa> best bet is to go there and probably waste some time making it working

15:50 <stipa> it would probably crash

15:51 <stipa> if it were some service unrelated to networking you could get away with it

15:53 <Armbian-Discord> <R​enegade> Therefore I wanna only try to get wireguard run somehow. Is it possible to have it installed at all? The kernel is 4.4.38+ on armv6l GNU/Linux. Or maybe it will be possible to run wireguard as docker somehow?

15:54 <stipa> idk, maybe the best would be to do an experiment on another board and see how it goes

15:55 <stipa> preferably indentical one

15:56 <stipa> at least you'll save some time there learning how to set everything up if it crashes

15:58 <stipa> if a docker wold be isolated enough from the main system and if you screw something up inside of the docker i guess it shouldn't affect the main system

15:58 <Armbian-Discord> <T​enkawa> You have to be able to add core wireguard support to the kernel somehow so that will be the difficult part though

15:58 <Armbian-Discord> <T​enkawa> Docker will require the stack support for it too I believe

15:59 <Armbian-Discord> <T​enkawa> Which will minimum require a kernel rebuild with the module enabled/hard compiled

16:01 <Armbian-Discord> <R​enegade> That's why I am afraid of. What was the minimum kernel where wg was introduced, which kernel do I need ?

16:01 <Armbian-Discord> <T​enkawa> Of course check for CONFIG_WIREGUARD in your kernel

16:01 <Armbian-Discord> <T​enkawa> It might already be enabled

16:01 <stipa> what about compiling and loading the module?

16:02 <stipa> it would probably crash, lol

16:02 <stipa> with core dump

16:02 <Armbian-Discord> <T​enkawa> I would recommend building it in..

16:03 <Armbian-Discord> <R​enegade> hum... well I'll see

16:03 <Armbian-Discord> <R​enegade> thanks to all

16:03 <Armbian-Discord> <T​enkawa> np.

16:03 <Armbian-Discord> <R​enegade> cross fingers

16:03 <Armbian-Discord> <R​enegade> 😄

16:03 <stipa> good luck

16:04 <Armbian-Discord> <T​enkawa> stipa: I don't even like that my ipv6 is currently a module.. I keep forgetting to rebuild it

16:04 <Armbian-Discord> <T​enkawa> I don't like extra context switch calls

16:04 <stipa> as long as it works i guess

16:04 <stipa> if it works don't touch it

16:05 <Armbian-Discord> <T​enkawa> It works but modules add more logic (minor.. but some)

16:06 <stipa> it's cool baked in for sure but sometimes it's faster to just compile the module

16:07 <stipa> it makes sense if the compilation of the image is few minutes

16:07 <stipa> to bake it in

16:08 <stipa> but it can be enabled, idk where it should be requested

16:08 <stipa> in the armbian build

16:09 <stipa> on github somewhere

16:15 <stipa> i don't think it's a problem if someone want's some module in the next release but i guess it should be tested beforehand

23:07 <lanefu> There is a userspace implementation called wireguard-go that can be used

23:11 <Armbian-Discord> <T​enkawa> Yes however note their caveat "This will run on Linux; however you should instead use the kernel module, which is faster and better integrated into the OS"

23:12 <Armbian-Discord> <T​enkawa> Still is handy if needed... kinda reminds me of slirp

23:12 <Armbian-Discord> <T​enkawa> remember that?

23:14 <Armbian-Discord> <T​enkawa> Was great in the early modem days for what it did.

23:32 <nekomancer[m]> <Armbian-Discord> "<T​enkawa> Still is handy if..." <- slirp? or slip?

23:32 <Armbian-Discord> <T​enkawa> slirp

23:33 <Armbian-Discord> <T​enkawa> check it out on wikipedia

23:33 <Armbian-Discord> <T​enkawa> was handy on modems back in the day for emulating slip/ppp
