This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
appletviewer opens a window, so you need an active X11 / Xorg display. PuTTy can't provide that for you, you'll need something like Exceed - a program that can connect to the X server and display its contents.
Linux already has this by default mostly, although you might need to set some flags. For example, ssh has the -X flags that enables X11 forwarding.
