Toggles . . .
eekaiwei, are you using the SBSettings SSH toggle? I've had problems with SSH using the toggle. I can turn it off (after the phone restarts, which reactivates SSH), but I can't turn it back on with the toggle. The toggle just resets to off every time I flip it . . . It worked just fine on the tethered 5.0.1 jailbreak . . . 🙁
I'm not sure if this is your problem, but, if it is, I'm pretty sure it's an SBSettings toggle thing and not an OpenSSH thing. I can enable/disable OpenSSH manually using MobileTerminal, but it's not as convenient as a toggle . . . 🙁
Edit: Same problem as you WordMasterRice . . . I think it's just a bug with SBSettings and the toggle . . . 🙁
