ALE, 03-12-02 1407
Ok, I have tried the following 10 things (per advice from this list), and my 
Internet connection still does not work. Is there a way that I can remove 
-everything- related to networking and internet connection and reinstall the 
rpms from the CD? Normally, when I have a problem like this I do a re-install 
of the entire OS, but I am hoping that if I learn to fix this problem, then I 
will have to do less re-installs in the future and save time on computer 
upkeep.

10. Added the following to /etc/resolv.conf I decided to make the file like 
the computer that works, however, this didn't work either after starting and 
stopping /init.d/network and even rebooting.
/etc/resolv.conf file:
domain home.here
nameserver 66.56.65.7
nameserver 66.56.65.8
search home.here

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.

I ran this:
/etc/rc.d/init.d/network stop && /etc/rc.d/init.d/ipchains stop \
&& modprobe -r ipchains && /etc/rc.d/init.d/iptables start && iptables -L -n

rpm -e ipchains

and now I get this:

[root at tb1200 root]# ipchains -L -n

Chain output (policy ACCEPT):

but my Internet connection still doesn't work. Lan card still pings itself 
okay, and the router but not anything else. Please help. Thanks in advance. 
By the way, I also noticed that I have three new directories mounted under 
disk managment.

/dev/shm        /proc   /dev/pts

/proc would not "unmount" either. Does anyone have a clue as to why there are 
new folders and such? Do these have to do with DVD playing of midi sequencers?

        conflicts with ipchains which is active by default?
        "ipchains -L -n"
        /etc/rc.d/init.d/network stop && /etc/rc.d/init.d/ipchains stop \
&& modprobe -r ipchains && /etc/rc.d/init.d/iptables start && iptables -L
-n
        if it works now, `rpm -e ipchains`
