Re: [Etherboot-developers] [Etherboot-discuss] Make undionly issue, http works unsteadily

Hi Miller

	I worked out.  

	I believe it's a bug in v0.97. If I make from 0.97+ (current snapshot version), it does works!

	Thanks. You made me know a way of how to debug. 
	
	make DEBUG=http bin/undionly.kpxe

 
 
 
Thanks
 
Best Regards

Good day Sean,

Just curious: What version does gPXE report it is when you boot the one you made in RedHat Linux?  Maybe you could try enabling debugging in your build with:

make DEBUG=http bin/undionly.kpxe

It's also possible that you don't need to use the 'dhcp net0' command in the script you showed in your e-mail.  gPXE will already have received DHCP parameters if it was able to receive the gPXE script itself.  Try removing that line and see what happens.  Thanks.

Hi all

            I use following command in redhat linux to build my boot image.

             make bin/undionly.kpxe

            then I copy undionly.kpxe to TFTP Server and set DHCP option 67 to point this file.  In the DHCP server, there is another Option 67 in User-class (gPXE) pointing to boot.gpxe (it's gpxe boot script). The boot.gpxe's content is list below,

            #!gpxe
       ifstat
       dhcp net0
       kernel http://10.254.196.6/pxeboot/pxelinux.0 
       boot pxelinux.0


            When I boot PXE client first time, it can boot to pxelinux menu.  However, if I reboot PXE client immediately, it encountered some problem when executing following command in boot script.
        kernel http://10.254.196.6/pxeboot/pxelinux.0
            
            Error information: Could not fetch http://10.254.196.6/pxeboot/pxelinux.0: Connecting timeout (0x4c0a6035) 

            I tried to reboot PXE client again and again, and I got the same error.  If I wait about 2 or 3 minutes and reboot,  the PXE client could boot to pxelinux menu normally.

            I don not think it is due to the http server problem, I think there is something wrong when making undionly.kpxe file.  Because I tried to get the boot image from http://rom-o-matic.net/, and this file works fine, it has no any unstable issue as my described above. 
 
            Thanks in advanced.
            
            


Thanks

Best Regards
