Lokkit

[beorn]

I am new to Linux, but after using intalling Red Hat Linus 9, I find that Apache is working fine, but I cannot reach the site from other computers.

The Red Hat Linux 9 Bible suggests using the system tools indow called Lokkit to check that port 80 is open. However, I cannot find any reference to Lokkit or a Configure Firewalling window in the system, not, when I go back to my system installation disks can I find any such thing.

There's gotta be a simple way to check that ports 80 and 21 are open, right? But I am stymied.

Here's what I see in /etc/sysconfig/iptables:

# Firewall configuration written by lokkit
# Manual customization of this file is not recommended.
# Note: ifup-post will punch the current nameservers through the
# firewall; such entries will *not* be listed here.
*filter

COMMIT

I really do not know enough to determine whether this is evidence of a problem with my web server and ftp server being accessible on the net.

Thanks to anyone who can help.
