YaST from the Command Line

The Automatic Configuration in openSUSE 11.0 installation is good because you don't have to click Next so much, but now I am missing the button for opening SSH in the firewall.
Here's a one-liner to do it using YaST:

# yast2 firewall services add zone=EXT service=service:sshd

Try also:

# yast2 firewall help
# yast2 firewall longhelp
# yast2 firewall summary
# yast2 firewall services list
# yast2 -l
# yast2 FOO help

(Saying "yast" instead of "yast2" should work too, but there is bug 374259.)
