> Hi, I've installed debian 6 in a jail, from FreeBsd 9.1 x86-64 by followi=
ng the instructions from this thread. However, I also updated my /etc/resol=
v.conf inside the jail, but I get this error when I do ping:

ping is usually denied from within a jail (for security purposes).

Add the following to /etc/rc.conf:

jail_sysvipc_allow=3D"YES"

And then reboot.
