Looks like I setup the interface on the host that I want to PXE boot correctly. I am also able to ping it from the host machine on which I want to run the debugger. However, I am unable to ping the client once I run the command "gdbstub udp net0" on the client..
Any thoughts?

This is not specified in the gPXE documentation. You want the ".lkrn.tmp" file. (An .iso image is built using the .lkrn binary.) > 2) I get the following output: > > <snip> Are you able to ping 10.44.4.3 from the machine running gdb? Also, since you say that you just recently started to play: are you aware that there is a substantial amount of built-in debug code that can be enabled without having to go to the effort of using gdb? For example, if you are having problems with DHCP, then make bin/ipxe.iso DEBUG=dhcp will show you debugging messages related to DHCP. You can find some description of debug builds at http://ipxe.org/download#debug_builds HTH, Michael _______________________________________________ ipxe-devel mailing list ipxe-devel@lists.ipxe.org https://lists.ipxe.org/mailman/listinfo/ipxe-devel
