chroot

when I try tu use the chroot command, I always have:
chroot: No such file or directory

The result of 'which chroot' is /etc/chroot and when I type 'chroot <enter>', I have:
usage: chroot rootdir command arg ...

I've tried to "configure" the new rootdir in the same way as I did for anonymous ftp (create a directory rootdir/dev and creating the special files with 'mknod') but it still doesn't work.

Thanks in advance for your help

Benoit.

I need to know what system you're using, and the exact chroot command line you're trying to run.  Also, an "ls" of the new root directory would be good.

Remember that the chroot happens before the command is executed, so if you give a full pathname to the program (which is a good idea) it has to be relative to the new root directory.  Also, as you've guessed, if the executable requires any shared libraries or anything, you have to provide copies in the chroot-ed environment.

Like it says, you need to specify a command to run.
Try for example, chroot <dir> /bin/sh
(You do have to create a mini-tree, and you have to be root).
