How to Restart Jailbroken Apple TV

There are a number of different ways to restart your Apple TV. Depending on your setup, each one has it’s own benefits. I’ve listed a few of the different methods below.

MENU + DOWN
If you press and hold the MENU and DOWN button on the Apple TV remote for 6 seconds, the Apple TV will perform a complete reboot. Some people have mentioned that a downside to this is if you are running a tethered jailbreak you will have boot the device back up tethered. If you are running an untethered jailbreak – like GreenPois0n RC6 or newer – then this is probably the simplest method to reboot your device as it only requires the remote control.

SSH: killall AppleTV
This method requires you to SSH into your Apple TV using a client like Putty (or a Terminal) and issue the “killall AppleTV” command. Please note that the command is case sensitive. The benefit to this method is if you are running a tethered jailbreak, you will not have to get out your computer to do a tethered jailbreak. A downside of this method is it only works if you have a network connection to your device and you have to have a PC or other device to issue the command.

Pull the Power Plug
This is probably the most drastic method of all the ones I’ll list, but it works in a pinch. As you may expect, some people claim that using this method may be bad for your device. I personally try not to pull the plug on any of my devices, but I’ve occasionally had to use this method. If you are running a tethered jailbreak, this method will also require you to get out a computer to boot tethered.

Fix: Apple TV 2G Wifi Broken After Jailbreak

After doing an untethered jailbreak on my Apple TV 2G (ATV2) with GreenPois0n RC6, I noticed that if I rebooted the Apple TV my wifi would not reconnect. Disconnecting the power and plugging back in would not resolve the issue. After a bit of research, I figured out a quick fix to getting my wifi back:

Go to: NitoTV > Settings > Restart Lowtide

After the device rebooted, my wifi connection re-established itself within 10-15 seconds. To permanently fix the issue, I SSH’ed into the AppleTV and issued the following commands:

apt-get update apt-get remove com.nito.nitotv apt-get install com.nito.nitotv killall AppleTV

 

Update (2/20/2010): A number of blogs are reporting that greenPois0n RC 6.1 includes the wifi fix directly. So if you haven’t already flashed, just go ahead and use 6.1 and it should include the wifi fix. Additionally, you can always flash RC 6.1 over your current setup, but I find it easier just to either remove/install com.nito.nitotv or install OpenSSH from the nitoTV menu.

Update (2/16/2010): NitoTV recently posted on their twitter account the the wifi issue appears to be related to SSH — they recommend that you grab OpenSSH from the top of the nitoTV featured list and reboot to fix the wifi issues. You shouldn’t need to do both fixes (the commands above and the OpenSSH install), but it also shouldn’t hurt anything.

On Wednesday 16th February 2011,  said: the wifi fix is live!! thanks  and  for major contributions  to squelching the problem! it was an SSH issue and saurik has updated  openssh to 5.8p1-9. grab openssh from the top of the nitoTV featured  list and reboot and your wifi woes /should/ be history!!!

Note: If you are running a tethered jailbreak, it’s recommend you update to an untethered jailbreak such as the GreenPois0n RC6 jailbreak. fireCore also has out a beta version of their seas0nPass utility. However, with the untethered Windows version of GreenPois0n being out for Apple TV 4.2.1 devices, I don’t see why you wouldn’t just want to use the GreenPois0n release as it’s just as user friendly… well, at least as user friendly as a jailbreak can be.

XBMC Dharma Confluence Location

After upgrading my XBMC installation to Dharma Beta 1, I wanted to modify the menu of Confluence to add a button directly for Last.fm to make things easier for my wife. It was driving me crazy that I couldn’t figure out where the Confluence folder was, but after searching through some of the XBMC logs, I found the location. I figured I would post it to the internet in case anyone else is looking for it:

/usr/share/xbmc/addons/skin.confluence/

XBMC Live Drives Mounted as Odd IDs

Drives Mounted as Odd IDs? (UUID)

If your drives are showing up as long IDs that look similar to “5f3d2340-b3c7-4c47-ba9a-ceaa9e699a4f” (from df -T command), there are a number of things that may have caused this. I’ve found that if my partitions are all labeled and the nodiskmount flag is still present in my grub configuration, then I no longer have this problem.

How to Install NewzBook on XBMC Live

NewzBook is an application I wrote to centrally manage my downloads and media. It has integration points with various indexing sites, SABnzbd, media management, etc. I originally designed the application for the Popcorn Hour, but I am now using XBMC again. I personally use the XBMC Live variant, so I’ve written up some instructions so other XBMC Live users could also use my NewzBook app.If you haven’t heard of NewzBook before, I would recommend checking out this thread on the NMT forums which describes what it does… I’ve also attached a few screenshots after the jump below.

Set XBMC to Automount Drives

Whenever I install XBMC, one of the first settings I change is I enable auto mounting of drives. It’s a relatively simple change, but requires you modify a file on the filesystem.

For Ubuntu Lucid 10.04:

I’ve noticed that it’s not necessary to manually remove the nodiskmount option on 10.04 (grub2). The modifications that I used to make in /boot/grub/menu.lst on Ubuntu Karmic, I now have to make in /etc/default/grub on Ubuntu Lucid.. When I removed the nodiskmount on Ubuntu Lucid I started having some issues with the disks being mounted in odd ways (eg. my NTFS drive being mounted directly to /media). What I found is that instead of removing nodiskmount, if I just properly labeled my partitions, they would automatically show up properly — you can label your partitions using the e2label command.

As I noted in the comments below, you may still need to remove nodiskmount in Ubuntu Lucid to get your eSATA drive to mount (especially true for people who followed my Revo 1600 guide). What I found is that because the internal drive on the Revo 1600 is NTFS, it will cause the weird issues I mentioned above. If you happen to fall into this case, I would highly recommend you check out my article on Drives Being Mounted with Odd IDs. The article explains how to find the unique identifier (UUID) for your drive and manually create an FSTAB entry to mount your drive with your specifications each time the system loads. Now that I’ve wrapped my head around how FSTAB works, I prefer to use this method as it lets me set my own unique name, path, and other settings for how the drive is mounted.

However, if you’d still like to modify the grub parameters for other reasons, I’ve included the details below…

Open the file /etc/default/grub:

sudo nano /etc/default/grub

Find the line for loading your system (usually starts with GRUB_CMDLINE_LINUXDEFAULT) and make sure it’s not the commented out line that often comes default at the top of the file. Modify this line so it no longer has the nodiskmount option in it.

Save the file and close it. Ctrl+O, Enter, Ctrl+X.

Run the following line to update grub and then reboot:

sudo update-grub sudo reboot

For Ubuntu Karmic:

If you are still booting from the XBMC-Live 9.11 Camelot USB stick directly, this will be in the syslinux.cfg file. If you have installed XBMC to disk, this is in the /boot/grub/menu.lst file. 

To remove this flag from the menu.lst file, telnet into the XBMC machine (use the instructions from the sabnzbd install post if you don’t know how), then open up the file with your favorite editor:

sudo nano /boot/grub/menu.lst (you may have to enter your root username and password — typically xbmc / xbmc)

Arrow down to the first line under “## ## End Default Options ##” near the bottom of the file and on the “kernel” line arrow to the right until you see the “nodiskmount” text. Delete this text then press Ctrl+O [enter] to save the file then Ctrl+X to exit. Reboot your box and you should now see some new items in your file manager usually named something like sdb1 or sda1.

Determine Hard Disk Free Space from Shell

I have always noticed that when people ask the question ‘How do I figure out how much hard drive space I have left’ as it relates to the Linux / *nix shell, people always respond telling people to use the following command:

df

Output:

$ df Filesystem           1K-blocks      Used Available Use% Mounted on /dev/sdb5             56870784  22222576  31759324  42% / ... /dev/sda1               252960    122460    130496  49% /media/sda1 /dev/sda3            1441394492 1372242748  69151740  96% /media/sda3 

In the above example, everything is hard to read since it’s in units of one thousand bytes. On some systems this defaults to multiples of 512 bytes unless you specific the -k option. I’m surprised that they don’t mention that if you add one simple switch (-h for human readable), you can make the output much easier to read on most systems:

df -h

Output:

$ df -h Filesystem            Size  Used Avail Use% Mounted on /dev/sdb5              55G   22G   31G  42% / ... /dev/sda1             248M  120M  128M  49% /media/sda1 /dev/sda3             1.4T  1.3T   66G  96% /media/sda3 

In the above example, you can see that I’ve used 1.3 terabytes of my main system drive, leaving me with 66 gigabytes free.

Side Note: You can also find out what file system type you are using by running the following command:

df- T

And it will produce the following results:

Filesystem    Type   1K-blocks      Used Available Use% Mounted on /dev/hdb1     ext3    19228276  14737848   3513680  81% / tmpfs        tmpfs      383960         4    383956   1% /dev/shm

(The second column is the type)

Send Command to XBMC to Start Music

You can use the following command to remotely start music playing on XBMC. The examples below were sent while I was SSH’ed into the XBMC machine. As you’ll notice from the music paths, I am using some of the ‘special’ paths which call up the LastFM tags of Rap and Alternative.

Start the LastFM Rap tag playing:

xbmc-send -a "PlayMedia(lastfm://globaltags/rap)"

Start the LastFM Alternative tag playing:

xbmc-send -a "PlayMedia(lastfm://globaltags/alternative)"

To play a tag that contains a space in it’s name, you must URL encode the space in your request (eg. replace all the spaces with %20). For example:

Start the LastFM ‘Classic Rock’ tag playing:

xbmc-send -a "PlayMedia(lastfm://globaltags/classic%20rock)"

I should note that each LastFM request is mutually exclusive of the other. Meaning each time you send a new PlayMedia request, the old genre/tag will stop playing and the new one will start playing.

I’ll add to this later when I start documenting some of the various URLs and functions that can be used to start playing music. A list of functions that can be sent can be found on the XBMC wiki.

Upgrade XBMC Live to latest SVN

See below for some short instructions on how to upgrade your existing XBMC Live installation to the latest SVN version. These instructions should also work for regular XBMC Linux users as well. It is particularly important to update your XBMC to the latest SVN version if you plan on using some of the latest and greatest plugins and skins. For example, after I installed the Aeon65 skin I noticed that the skin would crash when I would go to certain views… many of the people on the forums recommended upgrading to the latest XBMC build so I did exactly that…

Fix Revo NVIDIA Driver Error

After running an upgrade ‘sudo apt-get upgrade’ and ‘sudo apt-get install xbmc’ to get my system up to date (to the latest SVN) I started getting the following error:

XBMC needs hardware accelerated OpenGL rendering.
Install an appropriate graphics driver.

Please consult XBMC Wiki for supported hardware
http://xbmc.org/wiki/?title=Supported_hardware

The first time I had this happen to me, I spent a number of hours trying to figure out how to get my system back up… but by 3 am I gave up. The next day, I reran the XBMC Live installer and got my system back up. This time, I didn’t want to have to redo all the changes I made, so I wanted to fix things. I did a bit of research and this time I tried to directly install the nvidia drivers right away before mucking around with my configuration.
