What about virtual servers? Rather high overhead, but it's practically like giving them their own machine. I don't know how well it would support X applications, though, and I'm not sure that it actually allows you to lock users out of the rest of the machine. ----- Original Message ----- From: <lonnie@outstep.com> To: "Dan Nelson" <dnelson@allantgroup.com> Cc: "'freebsd-questions@freebsd.org'" <freebsd-questions@FreeBSD.ORG> Sent: Wednesday, December 19, 2001 23:20 Subject: Re: FreeBSD and restricting users > Thanks Dan, > > This is the same solution that I have already found from the Linux side as well > and is currently not an option for our particular impolementation. > > We really need to be able to limit the users from navigaiting out of their HOME > directories for this particular SPECIAL project. > > I just saw something on the FreeBSD website about "sandboxes" that might be > interesting in this respect, but I am not sure if it would be possible to put > each user graphicl login session into a "sandbox". > > Best Regards, > Lonnie > > Quoting Dan Nelson <dnelson@allantgroup.com>: > > > In the last episode (Dec 19), Lonnie Cumberland said: > > > The basic problem is this.
