La résolution de nom ne marche pas dans Busybox avec les outils de développement (libc, gcc, ld) de Ubuntu 10.04 (version actuelle ce jour).
En effet, dans le fichier busybox_unstripped.out créé lors de la compilation on peut voir que les fonctions suivantes ne sont pas disponibles dans un éxécutable statique.
Ce qui rend nslookup inopérant.
