FOG with ubuntu server 14.04 - my experience

[Tom Elliott]

As you’re using DNSMASQ in a Proxy setup ( I imagine ) you’re absolutely correct that you need to either make a copy or link to undionly.0 (or whatever filename you’ve specified in the dnsmasq.conf file.)

@Tom-Elliott Yes it`s correct i use dnsmasq only with a proxy setup. Like i said a symlink to undionly.0 seems dont work … but a copy… seems illogical, eventually i have misspelled but i copy the line from the manual
ln -s /tftpboot/undionly.kpxe /tftpboot/undionly.0
After that a PXE boot was not possible it cant find the file. With cp /tftpboot/undionly.kpxe /tftpboot/undionly.0 it works…

@robin-masters Symbolic links have never worked for me in Fedora. I’ve always had to make a copy.

Hi, try relative link instead absolute.

ln -s undionly.kpxe undionly.0

Hey lol it works… tried before again with ln -s /tftpboot/undionly.kpxe /tftpboot/undionly.0 and it definitively dont work.

ln -s undionly.kpxe undionly.0 works now… oO

Tried pxe boot from Dell Optiplex 790 and 7010

Thx…for this.

Under the text: "Make a symlink for the undionly.kpxe file so dnsmasq can find it. " eventually it`s better to use here the relative link it should work for all systems?

@Wayne-Workman , it’s for you.

It’s work for all system, I think it’s a tftpd server limitation.

@ch3i fixed.

I guess this is for security reasons. tftpd is not allowed to leave the “cage” of /tftpboot … not even to follow a symlink back into the cage. “Keep it local”.
