Q: I installed OpenSSH, but I can't figure out how to turn it off. It's eating all my battery power, and the iPhone already lasts only five minutes, so now it turns off before it even starts.

A: OpenSSH does not use any battery power except when you are actively talking to it. It isn't even running. It is just a data structure in the mind of launchd, which is always running, OpenSSH or not. There are no good reasons to deactivate OpenSSH on your phone.

Q: Wait, no good reasons? Everyone has the same password, and I keep hearing that passwd is broken. Without the ability to change passwords, my phone is going to become one of those spam slaves I keep hearing about (and that's got to use battery life... serious battery).

A: Actually, you've simply been corrupted by NullRiver. Their old "BSD Subsystem" package was slowly falling apart over the last year, and they never had the guts to admit that and switch to Telesphoreo. The userspace environment installed with Cydia has now and always did have a fully working passwd. Changing your password is simple and safe. (You should do this, by the way.)

Q: How do I do, well, anything, with MobileTerminal? It seems entirely broken and completely unusable.

A: MobileTerminal on 1.x was getting pretty awesome. This is a program that I (the author of Cydia, an utterly unrelated program) spent a bunch of time to get working at all on 2.0. The MobileTerminal author is spending some time at it, but in all honesty it's going to take a while to work.
