I had to upgrade from Leap to Tumbleweed so I could install the latest version of Docker. When I try to use yast to open up the firewall I get an error popup saying that
** YaST currently does not have a module for configuring firewall. **
Looking at software modules, I do see there is yast firewall module installed, so not sure why I’m getting this error.
It recommends that I used firewall-config or firewall-cmd. This is a server and firewall-config is graphical. I can’t find any online documentation for firewall-cmd. Since -h lists almost two screen fulls of options, I don’t want to slog through the man pages on a non-graphical interface.
This is a a throwaway test box so I just might disable or remove the firewall but that may not be the case for my next build.
