That might be the answer: If /bin/bash really exists (which is a "non-standard extension" on FreeBSD) _and_ it's a symlink, a test "if it's an executable" will probably fail. If you can place an _actual_ binary of /bin/bash, try that, and repeat the test. If not, specify its actual location for that user (using "chsh <username>"). This is bash's standard installation target on FreeBSD: % which bash /usr/local/bin/bash Keep in mind that things like #!/bin/bash are considered a "Linuxism" and therefore NOT PORTABLE. Butif I remember correctly, you can run "make configure" for the bash port and set an option to enable that kind of functionality. Anyway, check "ls -la /bin/bash" for anything suspicious, just to make sure _what_ permissions could have been denied, and _why_. > So, what is chroot good for??? See "man chroot": "change root directory". :-) PS. I have excluded the Fedora list you've been parallel-posting to because I'm not subscribed there. I assume that your question targets FreeBSD. If _not_, consult "info chroot" on your Linux distribution.
