3.4. Establishing a Connection

When you run the one-liner on your desktop machine (assuming proper priviledges to do so, of course), it will wait passively for a connection from a Palm device. On the Palm itself, you have to launch the Network Connection applet ( not HotSync), and it should connect.

To get there, simply tap on your Application launcher, then select Prefs. Inside Prefs, in the dropdown menu on the upper right, there's an option for Network. Select this, and then select your Unix profile (the one we configured earlier).

Figure 3-9. Connecting over PPP

Simply tap on the Connect icon on the bottom of the Unix profile, and it should begin a negotiation with your desktop machine. If you leave the window you launched the script from open, you should see something similar to the following upon connect (the verbosity is due to using the debug option we used when we launched it)

Figure 3-10. Signing on via PPP

As you can see, the Palm successfully connected to the machine, and was given an IP address of 10.0.60.200. To test this, I used the Palm OS Emulator (POSE) to test it (the port was /dev/ttyqe). I successfully connected, and was given access to the internet from POSE.

If you are not able to connect your Palm to the desktop over ppp, you will receive an error on the Palm. It will look like the image below. If you get this error, you should make sure you verify your port settings, speeds, and that the ppp module is loaded on the desktop.
