Mox netboot requirements of DHCP

Hi PhilPennock, miska

I had the same problem - default-arm-mvebu-turris_mox was empty and similar situation, custom configuration for TFTP and /srv is symlink to SSD.

I read this script https://gitlab.labs.nic.cz/turris/turris-netboot/blob/master/manage.sh (regen part).
I tried run netboot-manager regen, but without success.
The script check key ~/.ssh/reg_key.pub and if it does not exist, tries to create it. In my case, key wasn’t created (I don’t known why, but time is expensive for experiments). I created the key manually by ssh-keygen -t ed25519 -f ~/.ssh/reg_key -N "" -C "registration_key. After, I tried to re-run netboot-manager regen, but default-arm-mvebu-turris_mox was stay empty. I removed it and re-runed netboot-manager regen. Change! Script “said”: can’t create /srv/tftp/pxelinux.cfg/default-arm-mvebu-turris_mox: Permission denied.

Steps for help (for my case):

  1. check permission on /srv/tftp/pxelinux.cfg/ - I set 777
  2. remove default-arm-mvebu-turris_mox
  3. run netboot-manager regen
  4. check size of default-arm-mvebu-turris_mox
    4.1 if is empty, try to generate registration key and go back to step 2
    4.2 if is empty, I don’t known why :frowning:
  5. turn on your MOX and wait for some seconds
  6. run netboot-manager list-incoming
    5.1 if you see serial number, you’r win :slight_smile:
    5.2. run netboot-manager accept <serial>

Question for miska:

  • Before MOX I use TFTP for booting “rescue OS” with “incompatible” configuration
  • What’s right access/owner for /srv/tftp/pxelinux.cfg and /srv/tftp/turris-netboot?

My English is bad, I known :slight_smile:
