    Question [SOLVED] firestarter prevents networking -- even when stopped or uninstalled!

    I have an Ubuntu machine and a Windows Vista machine. I've used Samba to enable networking between the two machines.

    However...

    I've discovered, through trial-and-error, that firestarter is causing a problem.

    When I reboot Ubuntu, the two computers cannot see each other.

    But, if I start firestarter (System -> Administration -> Firestarter), then stop it ("Stop Firewall"), the computers can then see each other.

    1. I have to do this every time I reboot (start firestarter, then stop firestarter).
    2. I set firestarter not to start automatically (Preferences -> Firewall -> uncheck all options). That didn't help.
    3. Using Synaptic Package Manager, I uninstalled firestarter ("Mark for Complete Removal"). This also didn't solve the problem: In fact, I had to reinstall firestarter so that I could start it and stop it!

    Does anyone know what firestarter does to the system? I would like to uninstall firestarter and undo whatever it did, so that my Windows and Ubuntu machines can see each other.

    try
    Code:
     sudo iptables -F
    that will/should flush all the rules set by firestarter.

    If you are running behind a router like Linksys or Netgear you should be safe without the file wall. Try this.
    You can always install rcconf and then via the terminal window do"sudo rcconf" and deselect firestarter and it will not come up on the next boot.

    Re: firestarter prevents networking -- even when stopped or uninstalled!

    The way to stop the default firewall is to edit /etc/ufw/ufw.conf. Use your favourite editor eg:

    Code:
    gksu gedit /etc/ufw/ufw.conf
    Code:
    # /etc/ufw/ufw.conf
    # 
    
    # set to yes to start on boot
    ENABLED=no
    Just edit ENABLED=yes to ENABLE=no

    That will stop the firewall from starting on boot up.

    To stop the firewall without restarting in a terminal type:

    Code:
    sudo /etc/init.d/ufw stop

    I think the problem is not with the Firestarter but the underlying IPTABLES.

    https://help.ubuntu.com/community/IptablesHowTo

    You can check the current IPTABLES rules by following command :

    Code:
    sudo iptables -L
    That will list the current firewall rules. Please remove the rules which are causing the issue with samba.

    Post the resulting IPTABLE rules if you need any help

    Yes, that did the job. I needed to reboot both the Ubuntu and Windows machines, and then it worked.

    LOL, that is the hard way

    Code:
    sudo ufw disable
    bodhi@hardy:/$ sudo ufw disable
    Firewall stopped and disabled on system startup
    And to start :

    Code:
    sudo ufw enable

    There are two mistakes one can make along the road to truth...not going all the way, and not starting.

    I find ufw is easy to learn and facilitates writing rules for iptables.

    Once you get a set of tables built,

    Code:
    sudo iptables-save > rules
    Then to restore :

    Code:
    sudo iptables-restore < rules
    Helpful for saving / backing up your tables once they become a little complex

    Cool. Thanks for that.
