I usually keep customer facing systems physically disconnected from my internal lab network while customers have access, and if I need access I will SSH connect from the outside to get access.

Our Oscar server is on CentOS 5.5 at company LAN behind firewall. This may give the user ability to access to other resources on our LAN. What is the best solution to prevent the user to access other resources? Some options pop up my mind now are: iptable, chroot, rbash, separate LAN ... Any suggestion please? Best Regards, -- Jian
