#5 Jail does not work on FC4

[Anonymous]

I am running Jail on my server when I upgraded my
server from Fedora Core 1 to Fedora Core 4. Now jail
no longer works. I re-compiled the jail executable and
I get the following debug:

jail: original user's dir: /home/jail
jail: chrooted user's dir: /home/rsctest
jail: modified environment data: USER=rsctest
jail: modified environment data: LOGNAME=rsctest

jail: doing chdir(/home/rsctest)
jail: doing execve(/bin/bash)
Connection to eweb closed.

I see that it is getting to where it should invoke the
bash shell (also tested with /bin/sh) and then it just
closes the connection. What is wrong?

I get this error too, looking into it execve is missing
from my system. I am currently using Ubuntu 6.06.

On FC6, got the same error. To fix it, issue the following command:

cp /lib/ld-linux.so.2 /var/chroot/lib

This assumes that your chroot is located in /var/chroot
