RE: [Jailkit-users] Jailkit questions

[Jon Gullidge]

Hi Anson,

Look inside {jail}/bin, {jail}/usr/bin, in your case I think {jail} is /home/jail, so:
/home/jail/bin
/home/hail/usr/bin
Remove anything from in there you do not want. This should work fine as the jail innitialises outside of the jail so shouldn't be using any commands from within the jail :)
