I’m probably not following https://docs.resin.io/reference/resinOS/network/2.x/#connecting-behind-a-proxy correctly but I don’t understand how. Here’s what I do:
$ sudo cp resin-nuctest-2.12.0+rev1-dev-v7.1.7.img /dev/sdb $ sudo mount /dev/sdb2 /mnt $ sudo mkdir /mnt/mnt/boot/system-proxy $ sudo vim /mnt/mnt/boot/system-proxy/redsocks.conf
and I flash/install my NUC, it reboots and doesn’t work. I know my redsocks.conf is correct because on a development image if I get into the shell and copy the same file (from another USB stick) into /mnt/boot/system-proxy/redsocks.conf and reboot/restart redsocks service it works perfectly.
