Hier habe ich ja angekündigt, mich mal mit port knocking beschäftigen zu wollen. Da dachte ich noch, das knock kein Problem darstellen sollte. Leider bin ich beim Übersetzen dann aber über einen Fehler im gcc 4.1.0 gestolpert. Dabei wird das Makro PATH_MAX nicht richtig in limits.h deklariert. Glücklicherweise hat Dan Kegel in seinem Crosstool dafür schon einen Fix bereitgestellt, welchen ich einfach mal getestet habe. Und siehe da knock compiliert nun.
=> mein Vorschlag, den Fix in toolchain/make/target/gcc/4.1.0/110-fix-fixincl.patch abzulegen:
