A guide to generate and install U2F SSH keys using Flipper Zero.
1. I enabled JFFS custom scripts and configs
2. I enabled SSH
3. Via SSH I created a file named dnsmasq.conf.add in /jffs/configs/
4. I chmod 755 /jffs/configs/dnsmasq.conf.add to make it executable
(I don't think this is necessary)
5. I add all my dhcp static leases in the format:
dhcp-host=49:EF:0C:24:7F:16,D-Link-AP,192.168.2.10,1440
to this file.
6. I disabled manual assignment of DHCP leases
7. I reboot the router
Host remoteserver
HostName remoteserver.example.org
ControlMaster auto
ControlPath ~/.ssh/control/%r@%h:%p
ControlPersist 10m
