Lenovo L530 - dnsmasq issues

[Wayne Workman]

This is an interesting problem.

At work, I use undionly.kkpxe as my bootfile and this is handed out via DHCP. Works fine with the Lenovo L530.

At home, I use dnsmasq and undionly.kkpxe

I tried to network boot my Lenovo L530 at home and it gets the undionly.0 (copy of undionly.kkpxe) and acts like it’s going to boot, but then says:
PXE-M0F Can’t find default.ipxe (or something like that).

This isn’t really important but I thought I’d say something.

[Tom Elliott]

Is it finding undionly.kkpxe.0 or undionly.0?

[Wayne Workman]

@Tom-Elliott undionly.0

It appears to find that just fine and load it. Some FOG specific stuff shows on the screen, then it says it can’t find default.ipxe

A side note is network booting works fine for other equipment in the house.

Here’s what’s in /tftpboot, notice that undionly.0 and undionly.kkpxe are the same size, they are copies. I’ve never been able to get a symbolic link to work with dnsmasq.

Contents of /etc/dnsmasq.d/ltps.conf this configuration has worked for me for half a year without issue, and works for other devices on the network currently.

Here’s a video of it:

Like I said, confirmed that other equipment is fine with the setup at home… I’m using undionly.kkpxe both at work and home, laptop works at work but not at home.

I’m thinking that this model just doesn’t like how dnsmasq does it’s job… it is very hack-ish, you know.

And I’m using r3710 at home, and r3709 at work… couldn’t be that much of a difference lol.
