    Default openSUSE 11.x firewall settings

    Hi,
    how can i find out which firewall a opensuse 11.x pc is running and which its settings are?
    Iam about to update an old pc but i need to keep its firewall setting (especially its settings for blocked ports).
    my linux firewall experience is restricted to shorewall but i think i can handle this problem too.

    It is the file /etc/sysconfig/SuSEfirewall2, unless they did custom
    additions.

    The openSUSE firewall, called "SuSEfirewal2", by default closes all
    ports to the inside. The configuration is done to open some.

    It is just a set of scripts that configures iptables.

    Thanks, it seems that susefirewall 2 is not used:
    sudo /sbin/rcSuSEfirewall2 status
    says: checking that status of SuSEfirewall2 unused
    and
    sudo /sbin/SuSEfirewall2 status
    says: SuSEfirewall2: SuSEfirewall2 not active

    but a quick check with nmaps shows that only the ports 22/tcp, 111/tcp and 631/tcp are open
    is it possbile that iptables are used directly? Where could i find those settings?
    Maybe i can simply backup them and reuse the same files after upgrading/reinstalling the os

    Oh.

    ssh, sunrpc, ipp

    Possibly.

    That's above my pay grade :-)

    Better find out what script/service/whatever is setting up the firewall
    rules, and replicate or migrate.

    What iptables rules are active is certainly easy to backup to a file
    (just I'm not acquainted with it), but maintaining them is not trivial.
