Point of Sale
 

For anyone who is interested I have established a point of sale client application to which anyone using the 770 can open a touchscreen display and operate the POS app on the remote computer. You need only have openSSH installed and X forwarding enabled.

Let's first see if you can display our instance of "X Eyes" - xeyes - on your 770. If openSSH is installed, open the X terminal and type The POS computer will ask for a logon password: demo when the password is entered the 770 will download some fonts and textures, then get xeyes.

If that works, close the terminal to close the xeyes display. Open it again and type
The POS computer will ask for a logon password: demo
when the password is entered the 770 will download some fonts and textures, then get a START screen.

Any user ID from 1 to 5 is OK, then select FastStart and you should see the pizza menu. Any button that has '2X' on it is a double-tap or double-touch button.

I'll await for feedback to finetune the demo.

There is an entry in the Wiki that covers the setup for X terminal and OpenSSH.

The demo works for anyone running a desktop with an X terminal and SSH, too, as long as SSH is configured to allow X forwarding.

I got the openssh deb from here: http://maemo.org/maemowiki/Applicati...b23c6c80b9d4f2

From the description, it reads as if I need to be root to install it.
1. How do I become root? There's this thread http://www.internettablettalk.com/fo...ead.php?t=1098 about becoming root without flashing .
2. Is it really necessary to be root to install openssh or is the installer-workarounds mentioned in that thread above good enough?

I don't know the answers to the questions about being root to install openSSH on the 770. I hope someone who knows the answers will step in here and provide that.

Same problem here. I'm not sure how to run ssh directly from XTerminal.

Reggie; If you have SSH installed and X forwarding enabled you just open the terminal window and type that command in. Thoughtfix was requesting that somebody explain how to create an icon that could run a script or execute a command. That would be another way to bring up a display to the remote app.

I have tried it but got this:
Warning: No xauth data; using fake authentication data for X11 forwarding.
connect Connection refused at /usr/viewtouch/bin/vt_openterm line 128.

Remote: I'll try this tonight, time permitting.

Connection refused at /usr/viewtouch/bin/vt_openterm line 128

This means that I had the program down for a couple of minutes to refresh some of the data in it. Sorry about that.

Xauth I don't know about - something on your end. Are you sure that X forwarding is enabled?

status:
installed Xterm deb (from maemo.org applications), fine.
installed openssh deb (from maemo.org applications), fine.
opened xterm (was in extras).
entered /var/lib/install/sbin/setup-ssh.sh
clicked enter.

the keys were created, messages appeared, took about 15 minutes.

switched off, and on again.

Xterm again, entered
ssh -X viewtouch@demo.viewtouch.com /home/viewtouch/bin/openterm

error message, don't remember exactly, like "no ssh".

I tried /etc/init.de/sshd start
did not work, not found.

My guess: I need more privileges to start ssh. But someone else might know more?

Somebody from Marina Del Rey, California, was able to access the demo this morning. I'm accessing it from a Debian 3.1 desktop on an ongoing basis. Every little bit of info gets us closer. Thanks for your efforts so far. I think we'll have this nailed pretty soon.
