Thanks! This will explain things a lot better. For kicks, I added a file
magic that, although rare, may not be totally extinct from networks just yet:
file type:NETWARE_NLM; id:172; category:Executables; msg:"Novell NetWare
Loadable Module (NLM)"; rev:1; content:|4e 65 74 57 61 72 65 20 4c 6f 61 64
61 62 6c 65 20 4d 6f 64 75 6c 65|; offset:0;
That content match quite literally spells out "NetWare Loadable Module",
from offset zero. Can't get any more definitive than that, eh?
