Thought I'd ask here first, then report if it's a bug. Haven't used Nmap on Void before. I installed the latest version available in the repos (7.94). Still, no matter what combo of switches I use, it never shows hostnames. I even tried -R (reverse DNS lookup), it still doesn't report the hostnames. On the other hand, Advanced IP Scanner (Windows) resolves hostnames just fine. Avahi daemon is running, though that shouldn't make a difference as far as I know. Samba is also installed and smbd and nmbd are running just fine.
