mdns-scan is a simple tool that scans for mDNS/DNS-SD announcements on the local network and lists discovered services. It doesn’t require the full Avahi daemon; it directly uses multicast DNS queries.
$ sudo mdns-scan
+ nas [44:0e:be:62:58:a5]._workstation._tcp.local
+ nas._http._tcp.local
+ nas._smb._tcp.local
+ nas._qdiscover._tcp.local
In the past I used avahi-browse but it requires dbus, and in some systems I don’t use dbus.
