What's the preferred ruby way of listing hosts in a LAN or within a domain group? In particular, I am interested in 4 things: - Listing all connected hosts in a LAN / domain group (assuming there could be some hosts that appear and disappear, like wifi hosts -- ie. not just /etc/ hosts ). - Listing all hosts with a particular condition (say, allowing authenticated ssh connections). - Avoiding any hosts that are not in a trusted group (say, iptables). - Doing it fast. I'm interested in Linux, mainly, but if the solution is multiplatform, the better.
