AW: PXE boot with UEFI

[Frank Morawietz]

> have you considered tcp wrappers ?

Thanks for your input.

In my opinion, installation in legacy mode shouldn't work either if something like tcp wrappers or a firewall would hinder the installation in UEFI mode. IP addresses and ports would be the same.

Some additional information:

I picked the boot files from the local syslinux installation:
- /usr/lib/syslinux/modules/efi32/syslinux.c32  -->  syslinux32.efi
- /usr/lib/syslinux/modules/efi64/syslinux.c32  -->  syslinux64.efi
- /usr/lib/syslinux/modules/bios/ldlinux.c32  -->  ldlinux.c32
- /usr/lib/syslinux/modules/efi32/ldlinux.e32 -->  ldlinux.e32
- /usr/lib/syslinux/modules/efi64/ldlinux.e64 -->  ldlinux.e64

All boot files are in  /srv/tftp/fai/ , with modified names where necessary.

In comparison, the DHCP + TFTP logs of a working installation in legacy BIOS mode look like this:

So it looks like the UEFI tftp connection refused error happened where ldlinux should be transferred.

Is there anything else I could examine to diagnose further?
