In my last post I explained how I configured an ssh and a VNC server in one of my computers to control it remotely, so there'd be no need to have a keyboard or screen attached to it. The idea was to administer it from any of the other computers of my local network. Once I was able to do that (with Putty and UltraVNC in Windows machines and ssh and vncviewer in GNU/Linux ones) I thought it would be cool to control the computer with my Palm T|X PDA. The T|X includes WiFi so I only needed some good (and free) ssh and/or VNC clients for Palm:

- PalmVNC 2.0: thanks to this GPL licensed VNC client for Palm (compatible with Palm OS 5) I can see my computer's desktop in my PDA's screen and control it clicking on the screen with the stylus. You can rotate and scale the display and there are shortcuts and a special keyboard to, for example, simulate a right click of the mouse or the ctrl key.

- pssh: it is a free, open-source SSH 2 client for Palm OS 5. Once you install it, and after you connect to your ssh server, you'll have a text shell so you can control the computer through the command line. Nothing so visual as VNC, but very fast and powerful if you know how to make the most of it [1][2] (and, in theory, more secure, but read the note below for more information about that).

Note: VNC is not a secure protocol when used by itself and pssh, although based on ssh, warns you it is untested and probably insecure, so you may wanna use them with caution. Also, having open ports in your computer could pose another security risk. I have my firewall configured to allow connections to the ssh and VNC ports only from computers of my network (and I use VNC through an ssh tunnel whenever I can), but even that doesn't guarantee total security at all. If security is a critical issue for you, it's safest not to use this programs (servers and clients).
