[syslinux] syslinux 6.03pre17 + gpxelinux.0 + iso from http not working

Ady,

I had not previously tried three slashes, but have now. No difference
unfortunately. I've also tried using the web server on the same machine as
the PXE server and using 'http://127.0.0.1/Software/Util1.iso' as the
URL, again to no avail.

It appears not to be able to connect to anything via http or https. Presumably
it uses network settings (such as the gateway) provided by the DHCP server?

Our subnet on the dhcp server is defined like this:

subnet xxx.xxx.xxx.0 netmask 255.255.255.0 {
   option routers xxx.xxx.xxx.1;
   option subnet-mask 255.255.255.0;
   option broadcast-address xxx.xxx.xxx.255;
   option domain-name "ourdomain.com";
   option domain-search "blah blah blah, a few subdomains";
   option domain-name-servers xxx.xxx.xxx.2, xxx.xxx.xxx.3;
   option netbios-name-servers xxx.xxx.xxx.xxx;
   option netbios-scope "";
   option ntp-servers xxx.xxx.xxx.2, xxx.xxx.xxx.3;
   default-lease-time 1209600;
   max-lease-time 1814400;
   filename "gpxelinux.0";
   next-server xxx.xxx.xxx.xxx;
}

Regards,

Matt

Instead of "gpxelinux.0", have you tried "lpxelinux.0"
(included in
the same pxelinux package), with 2 or with 3 slash characters?

Ady,

I switched the dhcp server to lpelinux.0 and although it still doesn't work,
with two slashes and using 127.0.0.1 it doesn't fail immediately.
There's a delay of about 15 seconds between 'Loading
http://127.0.0.1/Software/Util1.iso...' and 'failed'. With three
slashes it fails immediately. Using any other IP or DNS hostname it fails
immediately as well.

Regards,

Matt

Well, 127.0.0.1 would be the client itself, which clearly won't answer.

Is there anything else I can try before I give up? I tried putting the verbosity
of tftpd-hpa up to 9 but it's not giving me any extra clues. Can I make
syslinux produce more verbose output of messages?

Matt
