I'm trying to unlock cryptdisks over wifi+ssh. It's fairly common to have luks disks + ssh, but I've never seen a tutorial geared towards wifi.
In fact, if you run
update-initramfs -u -v -k $(uname -r) as suggested in this post and every other post essentially, the script explicitly lists
wireless and a bunch of similar sounding kernel modules as excluded. I have gone about the business of editing out those exclusions, and also trying these patches
Nothing seems to work. On boot, the pi is not visible on the network (
interface wlan0 not found is commonly shown), and dropbear-initramfs never seems to "answer".
nmap never shows the device or port.
Rather than debug my particular setup (which I would appreciate)...
is there a canonical way to have dropbear-initramfs pick up over a wifi network so that I can retreive keyfiles or ssh in before cryptsetup asks for passwords
I'm on a PI-zero-w or 4b with latest raspbian
