    Lokkit


    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
    :INPUT ACCEPT [0:0]
    :FORWARD ACCEPT [0:0]
    :OUTPUT ACCEPT [0:0]
    :RH-Lokkit-0-50-INPUT - [0:0]
    -A INPUT -j RH-Lokkit-0-50-INPUT
    -A FORWARD -j RH-Lokkit-0-50-INPUT
    -A RH-Lokkit-0-50-INPUT -i lo -j ACCEPT
    -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 0:1023 --syn -j REJECT
    -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 2049 --syn -j REJECT
    -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 0:1023 -j REJECT
    -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 2049 -j REJECT
    -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 6000:6009 --syn -j REJECT
    -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 7100 --syn -j REJECT
    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.
