I've been attempting to create a jailed environment on my machine for
testing purposes, however I seem to have hit some problems. Having
followed the instructions laid down in the man page I have successfully
created a jailed file structure in /usr/jail which I can get into using:
# jail /usr/jail atlas 10.0.0.137 /bin/tcsh
Problems start when I attempt to add an alias for my network card. As
suggested in the man page I use the following line to setup the alias
from inside the jail:
# ifconfig vr0 inet alias 10.0.0.137 netmask 255.255.255.255
However this fails with the following return value:
ifconfig: ioctl (SIOCAIFADDR): permission denied
However I am root inside the jail (observed with id(1)) so I do not
fully understand why I would be denied this action. Also dmesg and top
do not work, exiting with:
kvm_open: short read
top: kvm_read for _ccpu: Undefined error: 0
I'm assuming that this is because /kernel inside the jail is linked to
/dev/null, but I wanted to make sure that this is normal behaviour...
If anyone knows why I can't apply an alias to my card Id really
appreciate it.
Thanks
Dominic Marks
