Do you Jail/chroot users when giving them shell access? If so, how do you do it. I'm looking at using ISPConfig, but I don't understand how you achieve this.
I'm not sure the version matters, but if it is different for the 2.x branch and the 3.x branch how is it?
ISPConfig 3 is a completely new software and has nothing to do with ISPConfig 2, so the version does matter.
