Since I initiated this thread, it seemed a good time to jump back in with an update.
Thanks to all the advice and clarifications posted here, I've managed to ssh into my Zaurus from both my Win2K workstation and my XP laptop. And sftp files. Thanks to all. The key issues, natch were:
1. install and run the ssh utils
2. understand which computer gets which IP address and
3. where to set them.
I think I've got that now. In a fit of pique I disinstalled dropbear when I installed the ssh suite. Will I regret that?
The bad news is this generally works as long as I don't want to do too much of it. I've noticed that can't-reestablish-a-connection-after-suspend syndrome, which I know I've seen discussed hereabouts. Somewhere there's a work-around which IIRC involves dropping and re-adding the usb modules?
Rather more interesting is that communicating with the Z plays hell with the W2K system. Everything works ducky until I close the connection and suspend the Z. Of course I can't reconnect to it, but even more of a pain is that this truly messes over the W2K system, but in a subtle way. The usb manager goes wonky and refuses to play. The system device manager retires to private life and takes up chicken farming. Communication with other usb devices, such as a memory stick, gets dicey.
And the system will not shut down cleanly. Various apparently random processes (they're not always the same ones) go zombie and refuse to exit for shutdown. The whole system hangs forever in the final stages of power-down. I have been reduced to Pulling The Plug out of the wall to reboot.
Now you may say what you like about the stability of Windows systems (and many do), but fact of the matter, it takes some hard work to do that to W2K.
Any ideas what's going on and how I can communicate with the Z and still unmount it cleanly?
I haven't experimented as much with the XP system, so I'm not sure how much of this happens there.
But there is one interesting pathology. On the laptop I use a USB powered cable to connect to the Z in lieu of the Sharp cradle. In theory, it runs the Z off the laptop's power while it's connected and up. When I first plug it in this is true, but the Z does not seem to recognize this as the moral equivalent of AC power. So it suspends in a couple of minutes and things get zarked. In particular, it stops getting power.
Is there a fix for this? I suppose I can go to the power setting and app and change the behavior under "battery" to "suspend-never" and then change it back when I'm finished, but it's kind of a nuisance. A short script would be nice. There must be a fer-chris'-sake-don't-suspend setting somewhere?
Mystified as usual,
