Syncthing on OpenWRT distribution

(miguipda) #1


I just discovered syncthing and think to my server situation. Let me explain.

As many other people I upgrade my router capabilities by changing its firmware where I installed OpenWRT (linux distribution). It upgrade my router function to a (file, web, printer, home automation) server functionalities.

Then as I connected an external harddrive to it I (as other users) need to have a syncthing package for this OpenWRT distribution to be able to simply sync my computer, portable and android tablet.

Could you please sincerely consider this need.

Thanks and have a nice daay,

Which hardware does it run? Link?

I use OpenWRT on my router too and it has the following hardware:

cat /proc/cpuinfo

system type : Atheros AR7161 rev 2 machine : NETGEAR WNDR3700/WNDR3800/WNDRMAC processor : 0 cpu model : MIPS 24Kc V7.4

Here is my current router hardware ASUS WL-500g Premium (Ver 1) :wink: system type : Broadcom BCM47XX processor : 0 cpu model : Broadcom BMIPS3300 V0.6 BogoMIPS : 297.98 wait instruction : yes microsecond timers : yes tlb_entries : 32 extra interrupt vector : yes hardware watchpoint : no ASEs implemented : shadow register sets : 1 kscratch registers : 0 core : 0 VCED exceptions : not available VCEI exceptions : not available

But as said I am really waiting my next router that will be a named Radxa Edge with something like those current existing Radxa Rock specifications

Have a nice day,

Miguipda :wink:

Go can be compiled for MIPS using gccgo so it’s possible in theory at least - in practice it might require some tinkering. How much RAM is there in these boxes anyway? If you start up syncthing on another box with the same set of files (or similar) that you want to sync, you can see how much memory it requires. If that is less than what is currently free on the NASes in question I wouldn’t recommend spending too much energy on this.

I’ve been meaning to get the new version of tor ported over to dd-wrt/open-wrt/asus-merlin so have bene getting the toolchain setup. I then started wondering about running SyncThing off my router as well. Did anyone ever try compiling for MIPS/MIPS32 and running it on a router?

My current folders aren’t super huge (a few thousand files each) and Win7 64 is reporting 34MB RAM used (peak set of 45MB) so it should fit on my router… possibly with some services turned off and without tor running.

Might be interesting to try in any case.

Did anybody try a MIPS build. An minimized resource build for RAM and CPU would be ideal.

I will soon use a beter router/server by using the new BananaPi router (BPI-R1 : It runs OpenWRT (router/server applications and allow to use a intern SSD hard drive). Here are some specifications.

I actually have a multipurpose router (AVM Fritz!box) running a MIPS architecture and I would like to add syncthing as a background job with low CPU priority.

Currently many cheap routers has >128MB memory and usb port available, so could be used as cheap backup node. Also routers could be good place for infrastructure services like relay servers. MIPS packages of strelaysrv could give a boost to the relay network expansion.
