Today I messed around with kopi synch and made a mistake in the ssh configuration.
Unfortunately I realized this AFTER I selected the synchronize command. The problem was that almost the whole zaurus froze because of the faulty ssh config. Kopi froze, of course, but so did busybox (i.e. applets were unresponsive, window controls did not work, keyboard shortcuts had no effect). The only observed functionality was the mouse cursor, which moved as instructed. Ah, yes, the suspend button also worked. Unfortunately I had not written down my dynamic IP address, so I could not ssh into it and kill kopi or ssh or whatever.
The only way out of it was the classic battery removal. And hence two questions:
a) This is supposed to be Linux, one application really should not freeze the whole system! Could someone explain what happened and why the whole thing froze?
b) How to gracefully recover from this?
