I created a chroot jail setup in Fedora Core 2 in a 64 bit OS. After creating the chroot setup and copied the necessary files from the system (like /etc/hosts, /etc/password ...), I tried running the apache in the chroot jail by the command '/usr/sbin/chroot /CHROOT/ /apache/bin/httpd -k start'. But this fails with an error ' httpd: bad user name nobody'. I have greped the 'nobody' part from both the '/etc/passwd' and '/etc/group' files and put it in chroot jail. There is 'nobody' user with id '99'. How to solve this? Any idea?

Check to see that you are using the correct root directory and that the jail is mounted if necessary. Do you have a shell installed in the jail? It's possible that the program requires the 'system' function to find the appropriate user ID, which requires a shell.

Maybe you could bind (using 'mount --bind') /etc, /bin, /sbin, and /lib read-only into the jail instead of building a new root file system? Does the program require temp files? How much of a system does it really require? Everything needs to be in the jail, but duplicating the info isn't necessarily the best way to do that.

Tried the 'mount --bind' options for /etc, /bin, /lib, /sys etc.., Even tried
copying the /bin/sh, /bin/bash files into the /CHROOT setup. But nothing helped. Same error occurs?

Can any body help?

Does the program run OUTSIDE of the jail? Maybe it changes user IDs when it runs and expects to have access to certain things.
