I am using dnsmasq on my router and have included a few config lines for pxe booting:


The problem is that during a pxe boot, the client fails the tftp portion with an error about not being able to find the file. Sniffing revelas requests like the following:
11:42:39.617240 IP > czar.tftp:  28 RRQ "pxelinux.0M-^?" octet tsize 0

I did some searching and it seems that the M-^? is a 0xff character which is being requested as a part of the filename. From what I've found, people suggest turning on a "option pad" on in the dhcp server software. (see <http://lists.soekris.com/pipermail/soekris-tech/2005-May/023322.html>) Is this a possiblity with dnsmasq?
