Find objects within folders in the SCCM Console hierarchy using PowerShell

Frustration


Ever since Microsoft's SCCM got the new-style System Centre console with SCCM 2012, I've been massively frustrated about how difficult it is to find items in the console once you've organised it with folders. Probably not too much of a problem if you're a lone SCCM admin, but as someone who works as part of a larger team who all use SCCM for slightly different reasons it can be a nightmare finding things like collections buried deep in the folder hierarchy.


Yes, I know that the console has a search function, and I know that there's a subtle "All Subfolders" button that magically appears on the Search ribbon bar sometimes. However that "All Subfolders" button has a few major flaws: 1) it doesn't always appear when it ought to, leaving you in a dance of clicking in the search text box, clicking away, clicking back in there, clicking away to another part of the console, clicking back, all the while crossing your fingers that the button will show up; 2) annoyingly clicking the "All Subfolders" button clears out any text that you may have foolishly typed into the search bar already before you remembered that you wanted to search the whole tree; 3) most importantly, the search results don't give you any information about the folder path that it found each item on, so it doesn't help you find that item (or similar items that may be in the same folder) quickly next time.


SCCM console rant over.


Journey


So over time I started casually looking around for ways to access this folder hierarchy info. These days there's a regularly updated set of SCCM PowerShell Cmdlets provided by the ConfgMgr team, this seemed an obvious place to start. Unfortunately, none of them even acknowledge that console folders exist. Next I set off on a hunt through WMI on the site server (using one of my favourite tools WMI Explorer (WMI Explorer downloads), but I couldn't any folder related properties on the collections/packages/etc themselves and couldn't find any obvious looking WMI classes. Real desperation now, open up SQL Management Studio and hunt through the Views in the site database. Nothing obvious. Brick wall hit. I went away and worked on other stuff for a while.


Enlightenment

Then early last week I came across this blog post by Peter van der Woude, that my previous searches had somehow missed: More than just ConfigMgr: Get the folder location of an object in ConfigMgr 2012 via PowerShell. Finally, answers - not only did that post contain this magic phrase: A good thing to know is that all folder information is stored in two classes in WMI, SMS_ObjectContainerNode and SMS_ObjectContainerItem. These two classes are the same for every object type., but it also had a working script linked, find his script in the TechNet gallery here: TechNet Gallery: Get the location of an object in the console via PowerShell


Moving Beyond


As great and useful as Peter's script was, it does have a minor flaw, and doesn't handle some edge cases. So I set off to use his information to write my own. The minor flaw was that his script requires hard coding your SMS Site Code and Site Server names into it. I can see the reason for that, especially as it means that his script has no external dependencies (other than the ConfigMgr infrastructure, obviously) but it still bugged me. More problematically, I hit an edge case that it didn't handle within my first few uses of it. Some objects (of different types) in SCCM can share the same SCCM IDs. So a Collection, a Query and a Package could have the same 8 character ([site code][5 hex digits]) ID, as all of those objects have their own numbering starting from XXX00001 and counting upwards. So using Peter's script, you don't always find the object that you're actually looking for, and, as his doesn't echo the name or type of the object that it's showing the hierarchy for, it can get quite confusing if it's not showing the info for the item that you're expecting.


Nirvana (or Farvana)


So, I've written my own PowerShell function to do this: Get-SCCMObjectLocation, find the code on GitHub, here GitHub: Get-SCCMObjectLocation.ps1. There's a bit more code here than Peter's versions, but this now outputs the object's name and type (so that you know you haven't made any typos, and you really have found the droids object you were looking for), and if there are multiple objects with the same ID, it lists them one by one. It also gets the site code and site server name from the ConfigurationManager PowerShell provider, though this does mean that you need the SCCM console installed on your machine, and you need to change to ConfigurationManager's PSDrive before running it.


Usage:
PS C:\>Get-SCCMObjectLocation -SMSId "ABC001BB"
root\Racked Server Drivers\Dell\PE1950-Microsoft Windows 2008 R2 SP1-OM7.3  [SMS_DriverPackage]

PS C:\>"ABC000CC" | Get-SCCMObjectLocation
WARNING: Multiple objects with ID: ABC000CC
root\x64\Test\Win 7 Ent x64 with Office 2010  [SMS_ImagePackage]

PS C:\>Get-SCCMObjectLocation -SMSId "ABC00166" -SiteCode ABC -SiteServerName sms01.example.com

Kindle Weather Display pt4 Putting it all together

By this point, if you've followed the previous posts in this series, you should have a server that's downloading weather info from a weather service, and converting that into a Kindle friendly PNG image, and you should have a Kindle that's been jailbroken, has working USB Networking (and SSH access) and has the Kite application launcher installed on it. Congrats, now let's put it all together and finish this crazy thing off.

Setting up the Weather Display on the Kindle


Find the "kindle" folder in the master.zip file you downloaded previously, or get the files from the "kindle" folder on GitHub.

Copy the "init-weather.sh" file into the "kite" folder on the Kindle. Then create a new folder called "weather" and copy both "display-weather.sh" and "weather-image-error.png" into it.

Open up the "weather\display-weather.sh" in a text editor (the same one that understands Unix line endings from above) and change the line that contains "http://server/path/to/weather-script-output.png" to the web server and file location that you set your weather script up on. When you save the file, make sure that you select Unix style line endings (this will probably be an option on the Save As dialog). Safely Remove and unplug your Kindle.

Now you're ready to test everything, you should see a new "PDF book" on your Kindle's screen called "init-weather.sh" if you don't, then switch your Kindle off and back on again. Select that and your screen should flash a few times and then either show your current weather, or show a warning sign and "Weather Image Unavailable".

Either of those mean that everything's working on your Kindle and you've succesfully run a custom script on it, if you get the image unavailable message then check the web address you've put in for the picture is correct.

One other possibility here is that when you click the init-weather.sh your Kindle puts a loading circle in the top-left corner for a moment, and then flashes back to the Home screen, this probably means that either init-weather or display-weather have been saved with Windows line endings (some decompression/un-zipper apps "helpfully" translate the line-endings for you when you extract text files, yours may have done this) just open the files up in a text editor and make sure that they're saved with the Unix line endings option select and try again.

One thing you'll notice when you've successfully got the weather scipt running is that there's only one way to exit it, and that's to hold down the power button on your Kindle for 20 seconds or so and wait for it to reboot. While that's fine when everything's up and running it can get a bit annoying while you're just testing things (like getting connected to your web server, or playing around with the look of the weather page), one alternative is to drop a test-weather.sh file into the "kite" folder containing:

#!/bin/sh
/mnt/us/weather/display-weather.sh

This should show the weather display on the screen for a moment, and then dump you back to the Kindle's home screen.

Set up Cron On the Kindle

This is it, we're nearly there now, just need to set the Kindle up to regularly check back with the server for an updated weather picture. Cron is how we do that.

Firstly, if you've never used Cron before, read up on Cron at wikipedia and follow links to further info if needed. I can also recommend searching for something like "crontab calculator" or "crontab generator" and using one of those to help build up your cron line, or running a search for "cron" on SuperUser.com.

Now you need to SSH into the Kindle again, you know the drill by now, switch on USB networking on the Kindle, plug it in and reconnect to it with Putty.

Once you're SSH'd into your Kindle, mount the file system for editing:
mntroot rw
Edit the CRON file in vi (a command line, text mode, text editor) (unbelievably *nix people like this thing and even fight religious wars over how much better it is than other text mode editors, like it's still 1980)(http://en.wikipedia.org/wiki/Vi)
vi /etc/crontab/root
A list of the jobs in the root cron file should appear:
*/15 * * * * /usr/sbin/checkpmond
*/15 * * * * /usr/sbin/tinyrot
*/60 * * * * /usr/sbin/loginfo tmpfs
*/60 * * * * /usr/sbin/loginfo localVars
*/60 * * * * /usr/sbin/loginfo memusedump
*/15 * * * * /usr/sbin/loginfo powerdcheck
All we need to do now is add the display-weather.sh script onto the end, mine's set to run every 6 hours, starting at just after midnight.
Try 10 */6 * * * /mnt/us/weather/display-weather.sh



Move the cursor to the end of the final line (using the arrow keys), press "i" to switch into "insert" mode, press Enter for a new line, and then type in your cron line, press Escape to leave Insert mode, and then press ":w" to save the file, and then ":q!" to exit vi. There, wasn't that straightforward and obvious! For more help with vi commands and a tutorial, consult your favourite search engine.

Your crontab file should now look something like:
*/15 * * * * /usr/sbin/checkpmond
*/15 * * * * /usr/sbin/tinyrot
*/60 * * * * /usr/sbin/loginfo tmpfs
*/60 * * * * /usr/sbin/loginfo localVars
*/60 * * * * /usr/sbin/loginfo memusedump
*/15 * * * * /usr/sbin/loginfo powerdcheck
10 */6 * * * /mnt/us/weather/display-weather.sh

And then you restart Cron, to read the new job details, by entering:

/etc/init.d/cron restart

Which should give an output like:
[root@kindle root]# /etc/init.d/cron restart
system: I cron:def:stopping crond
system: I cron:def:starting crond
[root@kindle root]#

Note: while you can set the Cron repeat interval to very small amounts of time when testing, I really wouldn't advise setting it to repeat any more often than every 5 minutes, as to get in there and change Cron's settings you need to wait for the Kindle to come on, turn on debug mode, turn on USB networking mode, SSH in and adjust the timings, all before the weather job kicks in again. That's not a quick process, you'll want to give yourself a few minutes.

Unplug, switch USB Networking off again, run init-weather.sh and enjoy your weather display.

And we're there!

Useful references and acknowledgements:

Thanks to Matthew Petroff for the inspiration and for putting in all the hard work to get all of the original scripts together and get this working on a Kindle in the first place.

Todo

Thoughts for future changes to this:
  • Wind - being a sailor, the wind conditions can be a useful thing to know, a couple of the weather feeds include this, either by default or as an option, so it should be possible to include it with some tweaks to the vbscripts, a tweak of the SVG template, and some new icons.
  • New icons - while the icons included in Matthew Petroff's original collection are clean and clear, I'm quite fond of the old BBC weather icons - they're what I grew up with - a member of the design team for the BBC's new visual style has made a set of icons in the style of the old classics, available here, it shouldn't be much work to swap these in.
  • Two other personal projects that I'm planning to do at some point are learn PowerShell and rebuild my 2003R2 based home server into Server 2012 whilst recreating most of WHS's functionality, as part of this I may rewrite the server-side VBscripts as PowerShell scripts.

Kindle Weather pt3 Setting up the Kindle

Back to the first post in this series.

Setting the Kindle Up


I'm doing this with a black Kindle 4 (non-touch) running Kindle v4.1.0, some of the following steps could change if you have a slightly different model (grey Kindle 4's may have older older firmware which give you more jailbreak options, they may also have the built-in SSH server enabled), I believe that most of this should work on a Kindle 3 (aka Kindle Keyboard) but I haven't tried that, so do it at your own risk.

Jailbreak your Kindle

I used the Universal method from here: MobileRead.com Kindle4NT Hacking.

Get SSH access to your Kindle (USB Networking) - attempt number 1


Plug in the Kindle and create a blank file named ENABLE_DIAGS in the Kindle's USB drive's root, "Safely Remove" the USB cable and restart the Kindle (Menu -> Settings -> Menu -> Restart).

It should reboot into diagnostics mode.

While you're in the diagnostics mode, plug the USB cable back in again and go to USB networking: Misc individual diagnostics -> Utilities -> Enable USBnet -> Exit. This will enable network access to your Kindle via USB.




Windows may fail to autodetect everything, if so you'll probably need to install a specific driver to access the Kindle over USB networking. This .inf file should do the job (I'm running Windows 7, Windows XP users need to do slightly more than this, good luck).

Once you have your driver set up, you'll need to configure the settings on your new network interface, set them to: IP 192.168.15.201 Subnet 255.255.255.0




Open your favourite SSH client (assuming that you have such a thing), I'm using Putty.

Try running Putty root@192.168.15.244 if that connects you're gravy, and your Kindle has a SSH server, if not and you get a "Connection Refused" then you're like me, so carry on.



Get SSH access to your Kindle (attempt 2, USBNet hack)


Download kindle-usbnetwork-xxx.zip from http://www.mobileread.com/forums/showthread.php?t=88004 extract it and copy update_usbnetwork_XXX_k4_install.bin onto your Kindle's USB drive. Safely Remove, unplug, then go into Settings, Menu, Update your Kindle. USB Networking should now be installed.

Restart your Kindle (not strictly necessary, but the Readme's recommend it).

Plug your Kindle in, and double-check the settings in D:\usbnet\etc (you'll need to use a text-editor that understands Unix line endings, Notepad won't work here, Notepad++, TextPad and others will work). In particular make note of the IP addresses, by default mine were set to:
HOST_IP=192.168.2.1
KINDLE_IP=192.168.2.2

On a Kindle 4, it's recommended to check that USE_VOLUMD is set to "true"

Following the README_FIRST.TXT from the usbnetwork zip:

  • Safely remove and unplug your Kindle,

  • You'll need to be in debug mode to run private commands, so, on the Home screen, bring up the
    search bar (by hitting [DEL] on devices with a keyboard, or the keyboard key on a K4, for example), and enter:

    ;debugOn

  • And now we can enable usbnet:

    ~usbNetwork

  • If you don't need to enter any more private commands, switch debug off.

    ;debugOff

  • Now, to actually connect to the device, we'll need to bring the shiny USB network interface the kernel prepared for us.

  • Plug the Kindle back in, wait for Windows to detect it, your Kindle should now be detected as something like a "RNDIS/Ethernet Gadget" or "CDC Ethernet Device network adapter" by Windows.

  • Then go into network settings, find the new network connection, and set the IPv4 settings to IP address 192.168.2.1 (assuming that's the HOST_IP that was set in your Config file above) and a subnet mask of 255.255.255.0.

  • To test it, open a command window and Ping 192.168.2.2 which should come back with a reply.

  • Now try Putty again:
    putty root@192.168.2.2

  • Hopefully this time you should get a connection and a warning message about the server's "host key". If so, say "Yes" to add the key to your cache, and then you should find yourself at a password prompt. A blank password works here, so you can just press Enter.
Congratulations, you now have SSH working. Careful, you can do a lot of damage here!

Install Kite (Kindle Application Launcher)

Now you need to install Kite, this lets you easily run custom programs on your Kindle. I tried installing Kite using the update package, with no luck, so here's installing it using the script method. First, download the kite.gz file from http://www.mobileread.com/forums/showthread.php?t=168270 and copy the kite.gz file onto the USB drive of your Kindle. If your Kindle is currently in USB Network mode, then you'll need to switch back to USB storage mode to copy the Kite installer onto it, as the usbnetwork command is a toggle, you can issue:
;debugOn

~usbNetwork

;debugOff
Once you've copied the files on, switch back to USB Network mode by issuing the commands again.
;debugOn

~usbNetwork

;debugOff
Plug your Kindle back into your PC again and test connectivity with a PING (depending what you've been doing in between, Windows may detect your Kindle as a new device again. If so, re-set the IP settings back onto the network adaptor as above, I went been to France for the weekend in between setting up USB Networking, so it happened to me). Connect to your Kindle's shell with Putty
putty root@192.168.2.2
Issue the commands to uncompress, and then run the Kite install script:
  • Mount the Kindle file system, type:
    mntroot rw

  • Move into /mnt/us:

    cd /mnt/us

  • Unzip the kite.gz file, and run the install:

    gzip -d kite.gz
    sh kite

Kite should now be installed, unplug your Kindle and then reboot it (Menu, Settings, Menu, Restart). As the reboot happens you may see a kite appear in the picture of the boy reading under a tree, or the land behind the tree may just flatten out, either are good signs. Once it's rebooted plug it back into your PC and check if there's a "kite" folder on the Kindle, if not create one (you may need to move/delete a file called "kite" first).

Kindle Weather pt2 Setting up the server

Back to the first post in this series

Setting up the server


Matthew Petroff's original scripts assume that you're using a Linux server, they're made up of a BASH shell script (that won't do anything on a Windows box) and a Python script (that needs an extra install of 3rd party software to get it working on Windows), as well as relying on a couple of small tools that either aren't available to us, or don't work as well on Windows.

So to get things compatible with pretty much any Windows box, I've rewritten the shell script as a batch file and the Python script as VBScript, both of those should just work on anything from Windows 2000 upwards, and I've found some replacements for the small tools.

What you'll need for this section:

Create a new folder somewhere on your server (preferably outside of your web server's root) and download and extract the zip file into it. This should give you three folders, one of which is called "Server-VBScript", and in there are three folders called "ServerNOAA", "ServerWU" and "ServerMet" inside each of these you'll find an SVG, CMD and a VBS file. Now you need to decide which weather service you'll be getting your forecasts from, they all make their data freely available for non-commercial usage but have different coverage, may differ slightly in their forecasts of different areas and provide slightly different info, whichever one you want copy that service's folder into the new folder on your server:

  • NOAA - the US Government's NOAA's National Weather Service. The major downside (for me) is that they only provide forecasts for the USA.
  • WU - Weather Underground, run from a US University, they provide worldwide coverage, and in multiple languages
  • Met - Her Majesty's Government's Meteorological Office (The Met Office) forecasts. They only cover the UK (this is what I'm using on my Kindle)

Pick whichever weather service you want, and feel free to delete the other folders if you don't want them.

Weather Services


Depending which weather forecast service you pick, you'll need to find your location code, and possibly sign up for a (free) API key to use it, I'll go though these:

NOAA
All you need is to find the latitude and longitude of your location, and change these in the long URL inside the ServerNOAA\weather-script.vbs file using a text editor, also note that the final parameter in that URL "&Unit=e" sets it to the temperature in Fahrenheit, changing it to "&Unit=m" will output the temperatures in Centigrade.

WUnderground
You will need to sign up for a developer account at Weather Underground, and then you can create a (free for the usage level that we'll be putting it to) API key to access the weather reports. Once you have that you just need to work out your city's code, acceptable formats are:
CA/San_Francisco | US state/city
60290             | US zipcode
Australia/Sydney  | country/city
37.8,-122.4       | latitude,longitude

Then open up ServerWU\weather-script.vbs file using a text editor, find the line with the long URL in it and replace "APIKEY", "COUNTRY" and "CITY" with your API key and location.

Met Office
As with WUnderground, you'll need to sign up for a free API Key to use the Met Office's forecasts, once you have that you can visit the following URL to get a list of the location codes that you can use:
http://datapoint.metoffice.gov.uk/public/data/val/wxfcs/all/xml/sitelist?key=API_KEY
Take the 6-digit location code from there, and your API key, and plug them into the long URL in the ServerMet\weather-script.vbs file using a text editor.

If you've got everything set up right, then when you double-click the VBS file it should create an SVG file in the same folder, showing your graphical weather forecast. You can view this SVG file with most web browsers.

Getting the Image Tools

(Side-story, looking for a suitable replacement for the RSVGconvert *nix tool to do command-line SVG to PNG conversions I went straight to my old, faithful ImageMagick, but every version of that and every option I tried seemed to choke on the embedded icons, eventually I came across Inkscape and discovered it had a decent command line interface, so here we are)

Next download Inkscape SVG editor and extract it into an Inkscape folder in your server's weather folder.

Then download PNGCrush and save the file in your server's weather folder.

Your folder structure should now look a bit like this (the "public" folder won't have been created yet):


Then go into the folder for the weather provider you're using, open the CMD file and edit it to reflect the paths of all these tools, and change the references to the "public" folder to point to the location of the folder within your web server's root that will be serving up the PNG image.

Now try running the CMD file in your chosen folder by double-clicking it, and with luck after a few seconds your 'public' folder should now contain a PNG image that looks a bit like this:

typical English weather

Scheduled Tasks


Finally you'll need to decide how often you want your weather image to update and set up a Scheduled Task in Windows to run the relevant CMD file as often as you want it. Personally I'm going to have my Kindle updating its weather display 4 times a day, so I'm setting my scheduled task to run every 6 hours.

Kindle Weather Display (from Windows)

I admit it, I'm interested in the weather. What can I say? I'm an Englishman and a sailor, I need something to talk about, and some way to know whether it's shorts weather, or if I need to take a brolly to work. Add in the fact that I love tinkering with gadgets, and have a mini server box sitting in the corner of my living room that spends large parts of the day doing very little, then I was very interested when I ran across Matthew Petroff's Kindle Weather Display blog post.


The only problem was that although he has all of the files available for download from that page, and a barebones hint on how to use them, it assumes a certain familiarity with Linux and its tools, and assumes that you're using a *nix server for the web server, and a *nix machine to do the install from, much of the Kindle hacking needed as a pre-req makes similar assumptions. I've barely touched Linux in the last 10 years (why deliberately make life hard for yourself when there's better choices out there?), was planning to set this up on my Windows Home Server box, and to do it all from my Win7 laptop. Clearly I was going to need to rewrite a few things, and work a few things out.

This is my tale of how that was done, so that you may read it, and do the same yourself.

To accomplish this you're going to need a few things that most people apparently don't have lying around their homes for some reason:

  1. A Kindle to dedicate as the display - while you could use the same Kindle that you use to read in bed at night, or on the train in the morning, that really won't be very convenient. Beware also that we're going to be hacking the Kindle and doing some (potentially harmful to the Kindle) things that will not be covered under your warranty. That said, if you hunt around you can find Kindle 4's for a fraction of their retail price on eBay, the one I'm using is an ex-shop demo unit that I got for a hair under £20.
  2. A Windows server (or at least a Windows box, doesn't necessarily have to be server hardware or a server OS sku) that will be switched on all the time, with an "always on" internet connection (the server itself doesn't need to be accessible from the internet). I have an old Tranquil PC SQA-5H that I use to run my home services, so that'll do me.
  3. A web server installed and running on your Windows server - all we need is a way to serve static PNG images over HTTP, so you won't need anything fancy. Personally, I'm using a Windows Server SKU, so I'm using the built-in IIS web server but pretty much any web server will do, Apache is probably the next most common, and I've used that for projects in the past.
  4. A basic plain text editor that understands the difference between Windows and Unix line endings.
    MS Word absolutely won't do, that's a Word processor not a text editor, Windows Notepad is no good either as it can't handle Unix style line endings. Something like Notepad++ or TextPad (which I'm using) would be perfect for this, many programmer's IDEs (such as Komodo, Eclipse or Visual Studio) also include this if you already have one installed, but don't go installing an IDE just for this as it really would be overkill.
  5. A basic familiarity with Windows and basic, common Windows tools - I'm happy to walk you through the Unix/Linux tools and commands but I'll expect you to know what you're doing on the Windows side

Warning: this is going to be a long one, so I'm dividing it up into a few parts over a few days, click any of the links to skip to parts you're interested in, or read the whole series to do it all. You can do some of the following steps in different orders, but I found it easiest to start with setting up the server while I was still searching eBay for a cheap Kindle.

Next: Setting up the server.

As someone who played (and loved) the first two Mass Effect games on the PC (after being badgered to just try them by a good friend), I'm on tenter-hooks waiting for the third installment's release on Friday (after the USians got theirs today).

As I'm moving between platforms these days and having a whale of a time in multi-player on XBox, including in the excellent multi-player section of the ME3 demo, I've had a few concerns about the PC/XBox divide, here are the answers I've found:

Tons of useful info there to keep me interested and informed until the final release!

Deploying Adobe LiveCycle Launchpad ES2 (9.5) for use by end users

As in many companies these days, our users don’t have administrative permissions to their PCs or to the various servers and services we give them access to. This means that the standard one-click web page deployment of LiveCycle Launchpad won’t work for our users, and also we have to configure the permissions within LiveCycle to give them the permissions needed. Here’s how we got it working:

Throughout this please replace any references to "LiveCycleServer" or port numbers in URLs with the appropriate ones for your environment.

Software Deployment

  • Log into your LiveCycle server's admin console (as a user with at least some admin privileges):
    http://LiveCycleServer:8080/adminui/
  • Then go to http://LiveCycleServer:8080/launchpad
    You should be able to download the .AIR executable from your server from this page, its address will be http://LiveCycleServer:8080/launchpad/installer/LaunchPad.air ).
  • (If you haven’t already) Sign up to Adobe’s AIR Runtime distribution agreement, this should get you a link to the direct download for the corporate deployable, bare-bones, all-in-one, AIR runtime installer.
  • Once you’ve been sent the link to the "Download Adobe AIR Runtime" page, you want to download the installer files under the "Adobe AIR Runtime Installer files: For use with a native installer or through CD/DVD redistribution using the Adobe AIR side-car configuration" heading.
  • Put your LaunchPad.air and AdobeAIRInstaller.exe files into a folder together, and you can now push out the two together, with a command line like:
    AdobeAIRInstaller.exe -silent -eulaAccepted -programMenu LaunchPad.air
  • Screenshot of the Server.xml file's contentsFinally the first time that you run the LiveCycle Launchpad app, you’ll notice that the servername, protocol and port are all set to defaults, and not to your server’s settings. Have a look in c:\Program Files\Adobe\LiveCycle ES2\Adobe LiveCycle Launchpad ES2 on a PC that has Launchpad installed and you should see a Server.xml file, copy that to your distribution location, open it up in a text editor and change the server details to match your environment. You can now push this file out along with the Launchpad app to give your users the correct default settings (I just use an Xcopy to put this in the folder after install).
Folder listing showing LaunchPad.air Server.xml and AdobeAIRInstaller.exe files ready for deployment

Now you’ll find that any users (who don’t have admin permissions within LiveCycle) who try to log into the Launchpad app will get an error like: "Server configuration specified here is invalid. Do you want to reconfigure the server settings?"

Error message after login - Server configuration specified here is invalid. Do you want to reconfigure the server settings?

Permissions

So, once users have the app, you need to ensure that normal users can use it without needing admin access all through the LiveCycle server.

  • Log into the LiveCycle admin console (as a user with at least some admin privileges):
    http://LiveCycleServer:8080/adminui/
  • Go to Settings -> User Management -> Role Management
  • Create a New Role, I called mine LaunchPad User, and obviously fill out the description field

  • Assign them enough permissions to use the Launchpad app, according to these articles they need these permissions at a minimum they’ll need "Repository Read", "Repository Traverse", "Repository Write", "Document Upload" and they’ll also need the PDFG User role assigned as well. Depending on your LiveCycle config, and which modules you have, you may have to give them additional permissions to other modules to give them all of the available modules. See these articles for more info on permissions needed: Adobe Knowledgebase: Unable to use LiveCycle Launchpad services without administrative role - LiveCycle Launchpad ES2 (9.x) and Adobe Forums: Launchpad ES2 - Logging In Issue.

  • Now assign these roles to end users (or preferably to a group to keep things tidy).

Done! You should now be able to deploy and give your users access to LiveCycle Launchpad. Next up (hopefully) deploying the LiveCycle ES2 PDFG Windows printer to your non-administrative users.

Dropbox

Just started using Dropbox to sync between my PC, server, Android phone and the web, it really is great. Easiest and simplest syncing solution I've found.

Had been thinking about it for a while, and then it was Gina Trapani (of TWiG fame) releasing her new Todo.txt Touch Android app that finally convinced me, as it uses Dropbox to do the behind the scenes updates.

If you sign up for Dropbox please use my affiliate link Sign-up for Dropbox as it will get us both an extra 250MB of storage on our accounts for free. Thanks.

Mozilla Weave Minimal Server Setup on Windows

So I've been following Mozilla's Weave project for while, and kept meaning to have a play with it. It's one of their experimental labs projects which recently came out of beta with a 1.0 release. Essentially it's a Firefox add-in that syncs and backs up a whole load of your settings and data back to a central server, including your bookmarks (and I have a lot!), saved passwords, preferences, history and open tabs. If, like me, you use more than one PC in more than one location then it's great knowing that Firefox is always setup how you like it wherever you are.

There are two parts to Weave; the Weave Firefox add-on (Weave is also available as an add-on for Mozilla's Fennec mobile browser), and the Weave server.

Most people install the add-on and sync their data back to Mozilla's Weave server, there's nothing wrong with that, all of your data is encrypted on your PC before it's sent to Mozilla's web server, so it's all secure and they have no way to access your private information. However you can also download the code for the Weave server and set it up on your own machine. Now, being that I have my own Windows Home Server* that's on 24/7 and accessible both within my home network and across the world via the internet I didn't really see the point in using someone else's server!

So I looked into it, and there are two options for installing your own Weave server there's the full server, which is a complex install and has all sorts of components that are only needed if you're going to act as a Weave server for many thousands of clients, or there's the Minimal Weave server, which has an incredibly simple server install (provided your machine already has all of the pre-reqs) and yet still implements the full Weave 1.0 API. Linux PCs are very likely already going to have most of the pre-reqs already installed (Apache web server and PHP for the Minimal server), Windows machines very likely won't.

I decided that as my Weave server is only ever going to be used by me, and possibly a few family members in the future, the simple install option sounded best! Particularly after I'd looked into it, and seen just how much effort was needed to install a full Weave server on a WHS box!

(Instructions on how to install an older version of the full Weave server on WHS are available on WeGotServed's wiki. note that this is for an outdated Weave version and won't SSL encrypt your traffic)

* A great little Tranquil PC SQA-5H series 1 server running MS Windows Home Server.


Stage 1: Setting up Weave Minimal server on Windows Vista

I don't like to mess up my server too much, it has a job to do, and does it well. I have a number of WHS add-ins installed, but have done the minimal amount of messing around on the server directly (and as a Microsoft certified server admin, this is against my nature ;). So to work it out, step one was to set Weave up on my Vista desktop, which luckily already happened to have a copy of Apache running, and I really don't care if this box gets messed up in the process!
Step by step instructions for how I did it are below.

Installing and configuring all required software for the Weave Minimal server:

  1. Download and install the Apache 2.2 web server (I cheated here as I already had Apache set up and working on my PC, stage 2 coming in a few days will have more detail for this step). Apache download page.
  2. Test Apache, point your web browser at http://localhost/ and make sure that you can see the Apache welcome page.
  3. Stop the Apache server -
    • Either using the Stop item in your Start menu under Apache HTTP Server -> Control Apache Server
    • Or by double-clicking the Apache 'feather' icon in your Windows system tray and clicking the Stop button in the Apache Service Monitor window that appears.
  4. Download and install PHP 5.2. Go to the PHP for Windows Download page scroll down to PHP 5.2 and click the Installer link under the VC6 x86 Thread Safe link. Run the installer, it will ask you the following questions after you Accept the licensing agreement:
    • Where to install PHP to, just accept the default that it offers you.
    • Select the web server you wish to setup: Select Apache 2.2.x Module.
    • Apache Configuration Directory, click Browse and go to C:\Program Files\Apache Software Foundation\Apache2.2\conf\
    • Ensure that the following Extensions are selected:
      • Extensions -> Multi-Byte Strings
      • Extensions -> PDO -> SQLite
      • Extensions -> SQLite
  5. Download the Weave Minimal server files from tobyelliott.wordpress.com/2009/09/11/weave-minimal-server/ unzip them using Winzip (or any other similar tool, Windows' built-in unzip tool can't unzip .tgz files) into a new folder called weave_minimal in the following folder: C:\Program Files\Apache Software Foundation\Apache2.2\htdocs
  6. Open Apache's configuration file via Start -> All Programs -> Apache HTTP Server... -> Configure Apache Server -> Edit the Apache httpd.conf... and add the following line to it at the bottom:
    Alias /weave "C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\weave_minimal\index.php"
  7. Start Apache
    • Either using the Start item in your Start menu under Apache HTTP Server -> Control Apache Server
    • Or by double-clicking the Apache 'feather' icon in your Windows system tray and clicking the Start button in the Apache Service Monitor window that appears.
  8. In Firefox go to http://localhost/weave/1.0/blah/info/collection if everything has worked you should see an "Authentication Required" box pop up, enter "blah" for the username and type anything as the password. The box will pop up again, just click Cancel, don't worry about this. You'll see a "File not found" web page, don't worry this is normal. Now if you go to the weave_minimal folder that you created earlier you should see a new file called weave_db this means that you now have your very own, working Weave server - well done!
  9. All that remains now is to create your user account(s) on the server and set up Firefox to talk to the server!

Setting up user accounts on the Weave server

Go to your weave_minimal folder that you created earlier in Windows Explorer, hold down the shift key and click the right-mouse button on a blank bit of the window, you should see a menu entry that says "Open Command Window Here" select that. Copy and paste the following line into the new window (Right-click -> Paste):

"C:\Program Files\PHP\php.exe" create_user

You can then press "c" to create your user and enter the desired username and password. Repeat for any further user accounts that you want to set up on your server.

Setting up Weave in Firefox to sync with your new server

  1. Install the Weave Browser SyncFirefox add-on from the Firefox add-ons website.
  2. Restart Firefox
  3. When Firefox starts up again it should take you straight to the Weave settings screen in Firefox's Options. Select Use a custom server from the drop-down menu. Fill out the boxes as below:
    • Server URL: http://localhost/weave/
    • User Name: The username you created earlier
    • Password: The password you created earlier
    • Click Sign In
  4. You'll be asked to type in a secret passphrase, you need to make a not of and remember this, it is a bit like a second password and is used to encrypt your data in Firefox before it is sent to the Weave server. You'll need to enter this and your user name and password when you set another copy of Firefox to sync with your Weave.
  5. If everything went well you should get a successful login and the Weave status at the bottom of your Firefox windows should show that it is successfully syncing
  6. Well done!
Next Steps

The server that we set up above is OK as a test server but is only accessible by Firefox on your one PC (or by other copies of Firefox on your home network if you enter the Server URL Weave's settings as your http://yourPCname/weave/ but it's not accessible over the internet at all. That's deliberate, the Minimal server doesn't encrypt your username and password as you login to Weave, these are sent over the network in clear text, not something you want to do over the internet.

Next time I'll be setting up Weave on my Windows Home Server box and taking advantage of the free dynamic domain name and free SSL encrypted connection that you get with WHS to allow me to connect to my Weave server over the internet using an SSL encrypted connection, so that my username and password are encrypted as they travel across the internet, and safe from anyone snooping.

EVE Central Market Upload Utility Trojan Keylogger Warning

Please see the update at the bottom of this article. I no longer suspect EVE Central or it's Market Uploader utility of any wrongdoing here.

So a friend of mine found that around a £1000 of money had been siphoned from his bank account recently (all in bank transfers of under £150). After talking to the bank about he found that the attacker had got into his bank account using the web login.

The question then became, how did they get his password? Like me, he works in IT so is pretty savvy about security generally, so had no idea how anyone could have got a keylogger onto either his home or work PC.

After much searching around he finally found this blog post a Mule in EvE: Learn and live to fight again that pointed to the fact that someone else had found a Trojan keylogger (a piece of malicious software similar to a virus that logs all of your typing and sends it to someone else on the internet) hidden inside the popular Market Upload utility from EVE Central. This is a popular tool that allows players of the game EVE Online to upload data about the ingame market place to a website where analysis can be run.

He rang me to let me know (as I also play EVE and have this tool installed), and sure enough a "deep scan" by Sunbelt Software's VIPRE Antivirus found the following trojan on my PC: Trojan-Spy.Win32.KeyLogger.acm, hidden in the "evec_upload.exe" file in the "EVE-Central MarketUploader".

Not good news, so one removal, uninstall and a few hours changing passwords later, here we are warning the rest of the public about this. As EVE-Central doesn't have any kind of public forum to post in, I'm putting this up here whilst I mail the developers for comment.

Please note that I am not blaming the EVE-Central developers here at all, I have no idea whether they are simply the victims of being unwittingly hacked themselves, or whether they are doing this deliberately. Also there is the possibility that this could be a false alarm and something in the way the Market Uploader was written is accidentally triggering a false warning in the anti virus software.

I am also most definitely not blaming CCP or EVE Online. CCP have made a great game that many, many people enjoy every day, and neither myself or EVE-Central are affiliated with them.


Update 20/8/08: Having carried out further investigation and emailed back and forth with Yann of Eve-Central it seems that we were too hasty assigning blame here. I no longer suspect EVE Central or it's Market Uploader utility of any wrongdoing here. I'm sorry for any misunderstanding or distress that could have been caused by this.

An up to date version of the VIPRE Antivirus doesn't pick up the "EVE-Central.com MarketUploader" as any kind of malware (or 'bad' software) at all.

From Yann:

I've been distributing the same package file since mid 2007. Its been at some time been listed as a Trojan all these major AV products, but detection had improved so the false positives were eliminated within a few update cycles.

It seems that some fairly old virus was written by someone using the same software that Yanne used to create the Market Uploader. This means that it has ended up looking slightly similar to an old virus, and has been at one time flagged up by many of the major anti-virus products, and then cleared again a few updates later as they fine-tune their virus detection.

This is a bit like if I used the same powerdrill to put up my shelves, as some serial killer used to do nasty stuff to people. Just because we both used the same tool, and both used it to drill holes, doesn't mean that I had anything like the same intention or outcome as the murderer.

Hmm tortuous analogy!
