The debugging machine does not need to be running the same version of Windows as the iSCSI-booting machine.

One host runs gPXE while the other runs GDB. gPXE supports debugging via serial port or over the network. For serial, you need a null modem serial cable. For network, you need the machine to be connected to a network with UDP port 43770 traffic allowed.

I managed to figure out how to enable it again (with the right #defines in config.h) and was able to dump information about each IPv6 packet passing through the system. So far so good! The next steps will be getting IPv6 packets to the next layer up (ICMPv6, UDP and TCP) so I can start working on stateless autoconfiguration.

You can achieve this by placing gPXE on your RPL server. The RPL-capable machines will download gPXE via RPL, and instantly become gPXE-capable machines.

Overview Fnrec is a tool that collects a trace of functions called before a crash or hang. It can be used to determine what led to the issue and which function was called last. How tracing works Fnrec uses the gcc -finstrument-functions compiler flag to trace each function call and record it into a memory buffer. The memory buffer has a magic number at the start to identify it as valid and not just random bytes in memory. As gPXE runs, it records each function call into the memory buffer. …
