[NTLUG:Discuss] some Qs

[LoneStar]

I have a couple of things I can't seem to resolve. Any help would be
greatly appreciated.

Red Hat 6.1 on a 686i
(Red Hat Support clains these are beyond their setup support guidelines)

1) I have a couple of real users (remote) on my system . When they log
in with an FTP client, they get full run of my system.  I've tried
various chmod configurations and anything other than 755 or 701 will
plavce then in the root dir and block net access to thier websites. Any
ideas of how to keep them from CDUPing past their public_html or user
dirs ?

2) I am trying to setup my firewall to deny access to port 23. I used an
exaple that came with the install, but when I activate the wall, it
locks down the system entirely to the point I can't even check my email
from my ISP. Any ideas of settings and/or a tutorial in laymen's terms?
