if the box is the one directly attached to the cable modem (ATT ?), then,
your cable modem is not really talking. The IP you got are one of those
reserved for internal use. My SB3100 cable modem will act as DHCP server
and assign my boxes some 192.168.* IP, if it fails to talk to AT&T.

#I am an amateur, but I think you last 2 ipchain rules are
#stopping the Internet surfing. I think you can do a
#ipchains -F and clear those rules. Which is almost as good
#as it being removed. Personally I have been using
#Iptables.

#Opps forgot something
#
#Before you say that your internet connection doesn't work.
#Try pinging a known address. Also try nslookup or dig.
#
#If you do and ip route show you can see
#your default gateway.

#You sure this isn't a name service problem? Can you ping an IP address
#out on the internet? Check and see what your /etc/resolv.conf looks
#like to make sure it isn't looking for a nameserver that isn't there.
#
#An IP address to try and ping would be www.google.com (216.239.51.101).

#Each one of those lines that begins w/ ACCEPT or REJECT is a firewall
#rule.
#
#Dump them with "ipchains -F" and see if your network works.....
#
#Then go out and get a book on firewalls and reimplement it correctly, or
#do without a firewall, but I don't recommend that.

#I think you'll have to actually reboot (gasp!) to make the kernel quit using
#ipchains. make sure your startup scripts don't try to initialize ipchains
#again on boot.
#
#does the rpm -e actually remove anything?
#
#
#shm is a shared memory device
#proc is ... proc ... reports live info from the kernel about different parts
#of your computer
#pts is for ttys
#
#huh? What does DVD have to do with MIDI?
#proc probably gets involved in both. shm might get involved in DVD. I don't
#think pts would involve either.

#By the way, I also noticed that I have three new directories mounted under

#/dev/shm /proc /dev/pts
#
#/proc would not "unmount" either. Does anyone have a clue as to why there are
