Learn about developing a YaST plugin by creating a plugin to manage SSH Tunnels. Creating SSH port tunnels along with corresponding iptables rules is a useful technique for being able to access virtual machines on a remote host that only visible on a private network. Managing and maintaining these connections via scripts and tmux sesssions is less desirable than doing it through a nice UI like YaST.

Note that the CLI tool https://www.npmjs.com/package/ssh-tunnel-manager has some nice ideas for managing groups and profiles that may be useful.
