Re: Power

I've got (one of) my Raspberry Pis powered from the USB port on my Samsung TV. I'm using a perfectly normal micro-usb cable, running between the USB port on the TV and the power port on the Pi. I turn the TV on, and the Pi powers up; I turn the TV off, and the Pi (unceremoniously) loses power, and c...

Re: pifs, the data free file system

Somewhere, deep, deep in the base-256 (ie. ASCII) expansion of pi, there exists the entire text of Carl Sagan's "Contact"...

Re: known_hosts and Remote Host Identification

Basically, this is your local computer complaining that the SSH signature of your Raspberry Pi has changed. Which, if you hadn't reinstalled your Pi, would be indicative of a potentially serious security issue (ie. something else masquerading as your Pi, and stealing your password). There are two so...

Are you really sure about that? The implication is that it's *not* set up properly.

Re: Wifi: fallback to access point if no available networks

I'm not sure how you would integrate it into ifup or ifdown...I don't really see a reason why you would want to either. Simply because I dislike having to constantly poll to see whether an action needs to be performed. 99% of the time there's nothing to be done (the wifi is connected), and on the o...

Re: Wifi: fallback to access point if no available networks

Yup, that looks very much like the sort of thing I was after. Hmm... I wonder whether it's possible to integrate it with ifup and ifdown to avoid the polling. I'll give it a go this evening. Integrating it with ifup is probably a bad idea: it would drop the access point just because a better externa...

Re: sudo?

The root account doesn't have a password, so it's natural that you don't know it. The use of su to become root disappeared several years ago, as sudo became more prevalent (although you can still use su to become a different user on the system). You don't "log in" to sudo, you use it to run a single...

Wifi: fallback to access point if no available networks

I've got my Pi wifi'd up, with a couple of network connections configured (as per the instructions at http://elinux.org/RPi_Peripherals). This connects the Pi to the appropriate network when the interface is brought up. But what happens if there's no appropriate wifi available? Does anybody know if ...
