    how to set up firewall - iptable rules


    I'm new to Yoper. After installing Yoper successfully, I tested the firewall here: GRC*|*Gibson Research Corporation Home Page**

    This is a print out of the test:

    Shields UP!! ? Port Authority Text Summary

    GRC Port Authority Report created on UTC: 2007-06-29 at 16:50:44

    Results from scan of ports: 0-1055

    0 Ports Open
    1050 Ports Closed
    6 Ports Stealth
    1056 Ports Tested

    NO PORTS were found to be OPEN.

    Ports found to be STEALTH were: 135, 136, 137, 138, 139, 445

    Other than what is listed above, all ports are CLOSED.

    TruStealth: FAILED - NOT all tested ports were STEALTH,
    - NO unsolicited packets were received,


    All ports were closed, but most were not STEALTHY. I would like to make all the ports STEALTHY. When I test my Slackware system, all ports are STEALTHY.

    Here is my iptables rules:

    root@Yoper /home/ron # /usr/sbin/iptables -L

    Chain INPUT (policy ACCEPT)
    target prot opt source destination

    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination

    root@Yoper /home/ron #

    Were is the script that loads and saves the iptables rules, and were are they saved? Is there a simple firewall for personal desktop use available for yoper by apt-get?

    thank you,

    I have no idea if there is something ready for Yopper but have a look the the linux from scratch firewall setup Setting Up a Network Firewall.

    this what is use under my Slackware 11.0

    Linux is not only an operating system, it's a philosophy.
