Apple Remote Desktop 3
I'm running Apple Remote Desktop 3.2 as we speak. I'm retired and I control my Macs through a WiFi connection from a MacBook Pro running 10.5.4. I have a G5 running 10.5.3 (haven't upgraded yet), a G4 running Tiger and two Yosemites (G3s) running Tiger. One of the G3s is running Tiger Server. I can control all of them from my recliner with my MBP. One of the G3s, the non Tiger Server, is on wireless but the rest are wired to my router. Couldn't live without Apple Remote Desktop and it sure does not require a server.
