Syslinux - Sep 2005 - PXEboot: can't find configfile on tftpd server

Hello,

I've got several machines which I'm trying to netboot, the setup is a
bootserver using dhcpd3 and tftpd-hpa. 

When a machine boots up, it gets an ip address and downloads pxelinux.0 from
the server, then it starts searching for pxelinux.cfg/[MACADDRESS]
pxelinux.cfg/0A0000F0 and so on. On the server side I see in the syslog the
client's DHCP-request and the client downloading pxelinux.0, but I never see
a client asking for pxelinux.0/* . 
Just to see if I have a configuration problem I downloaded the configfile by
tftping to my bootserver and asking for pxelinux.cfg/0A0000 which works
fine.
So dhcp and tftp apparently work fine, but where does is go wrong then? 

Any idea is welcome!

Best regards,
Lothar

the file pxelinux.0 is from the package: syslinux-3.11

add this line to dhcpd.conf:

next-server 10.0.0.1;

 You've got bitten by the dhcpd upgrade:
 http://wiki.ltsp.org/twiki/bin/view/Ltsp/DhcpdSiaddr
basically, from 3.0.3  ISC dhcpd does not provide by default the
'next-server' address
which was (until this version) filled in with the dhcpd server address.

If really search for that, why you do not try to use default configuration 
file, to see if you are not missing something.

How do you know the machine search for pxelinux.cfg/[MACADDRESS], if this 
happens then loading pxelinux.0 was success.

Are really named your MACConfig files with the proper MAC Addres with extra 
needed chars?

again try: pxelinux.cfg/default 
just try, I guess If you can see config errors then pxelinux.0 was already 
loaded.
