A few other students have reported the same problem: [help3002]⬈ but it's proving very difficult to pin-down. There's been no reported problems on a native-Linux installation, only when running the (same) binary within WSL-2. T appears to be a problem with individual students' laptop installations. I've sat with a few students and their laptops - some 'just magically' got it to work by reviewing the installation instructions, but others had no success (and started working with another student in the lab session). I've built a new binary which just annotates where it's up to in its execution. Download and make executable the modified binary: [CITS3002]⬈ Now (hopefully) if you just run d1-cnet-Linux-x86_64 STOPANDWAIT it should just crash as it was before. Now enable some additional debugging compiled into this binary with: D1=y d1-cnet-Linux-x86_64 STOPANDWAIT and it should list many of the functions that it calls to initialise itself and parse your topology file. Please post a copy of this output.
