How to configure firewall/ routing policy in Red Hat 7.1?

How to configure firewall/ routing policy in Red Hat 7.1?

Post by Raymond L » Sat, 09 Jun 2001 00:08:41



Hello,
        I used to setup my RedHat 6.2 to share my internet access for a few
machine. Now I upgraded to RedHat 7.1 and it seems that there are many
things new. First, the RedHat installation asked me to choose
High/Medium/No firewall setup. Now I run /sbin/setup and it shows that I
have chosen "High" level firewall. Well! I change it to medium, no or
customize, and it won't save my setting. I find my machine still deny
all in-coming request (ping or ssh, etc. from another machine). And when
I run /sbin/setup again, it show "High" again.

        What configuration file can I touch to set the config myself? I found the
/etc/sysconfig/ipchains to be suspect. But don't know how to manage it.
(I tried to change the reject to accept, then the whole file disappeared
after reboot.)

        Can someone provide some links on the firewall/routing setting on RedHat 7.1?

        Thanks a lot!

        Yours,
        Raymond

How to configure firewall/ routing policy in Red Hat 7.1?

If you suspect that the problem laid on ipchains, try to issue the command
"ipchains -F", this command will flush off all the existing blocking and
setting...

Cheers!
Andy

1. Red Hat 7.1 - Installing Red Hat packages after Red Hat is already installed.

How can I install packages that I forgot to install with the Red Hat
7.1 installation?

Here's my problem:
Various pieces of Red Hat keep saying that I am missing a file and
that it needs to be installed with a certain package (namely most of
the Kontrol Panel).  But I have been unsuccessful at finding where
this is done.  I am still a newbie with Linux, but I would assume that
there should be an "Add/Remove Programs" equivalent with Linux.

Please help!
