So you got that shiny new Netbook, installed Linux on it and carry
it along everywhere you go. The default enabled Firewall blocks
incoming traffic so you feel safe when connecting to that anonymous
WiFi network at your favorite fastfood restaurant. Unfortunately the
very same Firewall becomes quite annoying at home where it prevents
your system from discovering printers or blocks ssh.
You have the choice of either opening the ports permanently,
exposing your system in hostile networks, or having to use sudo to
enable or disable the Firewall. Well, not anymore with Firewall Zone
Switcher! With that little applet you can now switch the zone of
your network interface to ‘internal’ with only two mouse clicks when
you are at home. In an untrusted Network you just set the zone to
‘external’. And if you need some custom configuration you could set
the zone ‘dmz’ to have some open some ports or create a custom zone.
Firewall Zone Switcher is *not* meant to be some kind of ‘Personal
Firewall’ that confuses the user with all kinds of low level stuff.
It’s neither a Firewall configuration tool. That job is still left
to Admin tools like YaST. Firewall Zone Switcher settings are
temporary and are reset to the system defaults on reboot.
Firewall Zone Switcher consist of a DBus service and a system
tray applet. Both are written in python currently to have proof of
concept program quickly. Packages are available from the openSUSE
build service. You also need to update SuSEfirewall2 from that
repo. Source code repo is available at gitorious.
Keep in mind that the app as well as the patch to SuSEfirewall2 are just proof
of concept ie experimental so there will be bugs. Feedback welcome nevertheless
