Toto, we're not in Kansas anymore. chroot --userspec /bin/bash run info chroot You sure you're running FreeBSD? using chroot -u /bin/csh man chroot I can pretty much replicate your error as follows: root@stream:/home/jon # chmod -x bin/csh root@stream:/home/jon # chroot -u jon /home/jon chroot: /bin/csh: Permission denied root@stream:/home/jon # chmod +x bin/csh root@stream:/home/jon # chroot -u jon /home/jon ELF interpreter /libexec/ld-elf.so.1 not found Abort root@stream:/home/jon # Where the 2nd round of errors comes about since I did *not* bother copying all the linked "stuff" into the chroot. So maybe start by making sure the chrooted user actually has permission to execute the bin/bash in the chroot environment??? Sometimes error messages mean what they say. ;-) --Jon Radel jon@radel.com
