How can I launch an on screen keyboard, without a physical keyboard?

Question

I have installed Ubuntu 10.04 on a desktop, and do not have a keyboard that I can use with it. I would like to install sshd (secure shell daemon) so that I can access that computer, but I can't seem to get onBoard, the on screen, accessibility keyboard to launch. I am sure that it could be launched by typing `onboard' into the terminal, but clearly, I can't do that.

I have tried enabling it through System->Preferences->Assistive Technologies, by indicating `Enable assistive technologies', selecting onBoard as my preferred Mobility application, and then rebooting, to no avail.

Does anyone know of a way to either:

(1) launch the on screen keyboard, using only the mouse, or

(2) install sshd, through a package downloaded on this computer and transferred with a USB drive (remember, I cannot enter my password to gain root privileges)

Answer 1

I managed to launch the on screen keyboard by creating a text file on a USB drive with the contents "onboard\n", copying that text from the file to the terminal and continuing from there. I would recommend to anyone with this problem in the future to compose the shell script,

#!/bin/bash

onboard

and to execute it from nautilus.
