@Martin-IT-Systems said in Where do I find the file undionly.kpxe and default.ipxe:

Now to my question: on Github FOG Project / Backet someone has set under tftp a lot of ipxe so also the undionly.kpxe file. Can I use this or where do I get this so I can copy this into /tftpboot?

Sure you can manually download the files. BUT the files not being in /tftpboot might be a hint that the FOG installer never finished all the way to the end. I suggest you re-run the installer, carefully read what you see on screen, follow it’s instructions and it should take care of everything for you.

And where do I get the default.ipxe file or should I do it myself according to the instructions in FOG Wiki?

Same answer. The installer will create it when it runs all the way to the end.

Would there also have to be a dnamasq integrated into the network?

You can manually setup dnsmasq in your network if you think you need a DHCP Proxy. The FOG installer does not so this for you.
