Antwort: [Lugbz-list] Strace chroot /bin/bash ausgeführt

Tja Peter, diese Idee war wirklich die bessere...... :wink:

Im ersten Drittel sieht man auch schon das Problem

chroot("/bin/bash") = -1 ENOTDIR (Not a directory)

Sorry Bernhard, aber ich glaube du hast dich nur mit der Reihenfolge der
Parameter vertan.... ein Aufruf muß mit

"chroot <VERZEICHNIS> <BEFEHL>" erfolgen, nicht mit "chroot <BEFEHL>"!!

Grüße,

Günther

Hallo Peter,

ich habe deinen Rat befolgt und den Befehl strace chroot /bin/bash
ausgeführt er hat mir folgende Ausgabe geliefert !

Ich kann damit allerdings überhaupt nichts anfangen :frowning:
