Surely once you have it how you want it, you can just image the sd card?

I didn't expect a critical failure (and especially one due to an update) within a week. I still had a few things to set up before I wanted to do a proper backup.

And even if I did do a backup, if the update has an issue it would still auto-update on boot from the backup.

It is possible though right?

I would assume so, never tried it myself though and I'm not sure how to get the image back onto an SD card either but I would have thought it should be possible to backup like that.

Another alternative would be to backup the config files and hope they are still compatible with whatever version of raspbmc is re-installed after a failure. Although that too is something I would have to look into, which I was planning on once everything is how I like it.
 
I'm having a bit of trouble getting wireless to work on my Pi (I'm a bit of a linux n00b). I have the drivers installed and the dongle is being listed:

Code: 
pi@raspberrypi ~ $ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

However I'm a bit unsure of how to setup the config file for the wireless connection (I can scan for the ssid's succefully). All the examples I have found are with a password protected wifi (Mine isn't password protected, it is MAC address protected). This is what i have so far, but it isn't working when I do the command:

Code: 
sudo ifup wlan0

/etc/wpa.conf file contents

Code: 
network={
ssid="MYSSID"
}

What other parameters do i need to fill in?
 
Can't help you with that one. My RPi is connected by wired Ethernet, and my Linux laptop doesn't use the same wireless set-up as the RPi (it doesn't have a /etc/wpa.conf file).
 
Ok, I got it to work :D. Turns out I didn't need the wpa.conf file and I just had to add this to the "/etc/network/interfaces" file

Code: 
auto wlan0

iface wlan0 inet dhcp
wireless-essid MYSSID

and then run

Code: 
sudo ifup wlan0

and bingo

Code: 
wlan0     Link encap:Ethernet  HWaddr c8:3a:35:cb:ca:6b  
          inet addr:192.168.15.113  Bcast:192.168.15.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1205 errors:0 dropped:0 overruns:0 frame:0
          TX packets:912 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:618905 (604.3 KiB)  TX bytes:165336 (161.4 KiB)

I'm now posting this from my Pi over wireless N goodness :D.

Now to get flash working :cool:

There's no build of flash suitable for the Raspberry Pi. It's not x86. Your best bet is to compile Gnash, Swfdec or Lightspark which are open source (and incomplete) re implementations. Strictly for video you could use HTML5 for most youtube videos.

Interesting (and slightly nooby) question... If flash isn't supported, how does the Raspbmc YouTube add-on work?

You can download videos from Youtube in other formats such as .mp4, this is how the "download Youtube videos" apps work for browsers, I'm guessing the plugin does the same thing.
 
Has anyone had any luck setting RPi as a FTP server?

I have a 1Tb USB hard drive (powered by an external power lead). I'd like to have access to the hard drive where ever I go. I was thinking about this setup:

My home internet ----> my home router ----> Raspberry Pi with FTP client installed ----> USB hard drive


Can anyone see any flaws/anything that might go wrong? Thanks :)
 
Is it possible to use the Pi as a home CCTV system? Is the Pi powerfull enough to stream 2 channels of video and store it onto a USB hard drive? I'll have to be running Linux on it and the cameras will be wireless.

What software can I use, for the operating system and the actual CCTV IP Cameras? Any advice would be greatly appreciated.
 
In about 2 months there will be a camera specific to the Pi coming that's capable of 1080p30,

I have no experience with IP cameras though, so can't help there.
