Rolling FOG out to US Site

[Tom Elliott]

@george1421

myip=`ip route get 8.8.8.8 | awk 'NR==1 {print $NF}' | cut -d "." -f1-2`;

I’d recommend as:

myip=$(ip route get 8.8.8.8 | awk 'NR==1 {print $NF}' | cut -d "." -f1-2)

Sweet, I learned something new today.

@RobTitian16 You found the other issue I mentioned that the code copied out of the forums sometimes misses spaces that need to be in there.

For example this code

 [[_! -d /ntfs_]] && mkdir -p /ntfs #REPLACE _ WITH SPACES

gets converted into

 [[! -d /ntfs ]] && mkdir -p /ntfs

note the missing space after the second left bracket. That is why I included the text file (which I may not have fixed every occurrence when I was quickly hacking it up.)

Might be helpful if you’re going to use bash scripts to make sure there’s no mistakes in it.

[RobTitian16]

@george1421 Yep, I remembered it from last time.
I did download the file and transfer it to my FOG Server, which is when I had to use dos2linux to convert it as it was giving some unusual errors.
Apparently it really doesn’t like:

$sitelocal = "en-GB";
$uilang = "en-US";

As I’m getting this error:

@RobTitian16 nuts, that’s what happens when you do crud too stuff too fast while doing your real job.

Remove the leading dollar sign “$” from each variable, that should not be there on a set action.

As for the hint part I alluded to before… crud back in a minute.

[RobTitian16]

@george1421 haha, I thought that but just wanted to confirm before fiddling

[george1421]

@george1421 OK here is the hint.

1. If you schedule a debug deploy to your target computer.
2. Then pxe boot your target computer. After a few enter key presses you will be dropped to a linux command prompt.
3. From here you can enter fog and single step through the deployment tasks until you get to your postinstall script. If you script bombs out you can then work on editing your post install script. BUT what I recommend is to do step 4 and on.
4. Get the ip address of your target computer using ip addr show
5. Set roo’s password with passwd you can set it to anything you want.
6. Now from a windows or linux computer use putty to connect to your target computer.
7. At the command prompt key in fog to single step through the installation process.

Putty gives you the ability to copy, cut and paste as you edit the post install script.

[RobTitian16]

@george1421 Thanks!
Not sure why, but it’s still not copying the SetupComplete.cmd… I wonder if it’s because I made it on the FOG Server itself by just typing: “sudo vi SetupComplete.cmd” and then filling in the file with what I needed for the msi installer.

[george1421]

@RobTitian16 What you need to confirm is does the entire target path exist?

If I had to bet, I would say this path exists on the target computer c:\windows\setup and thats it. If that is the case you need to create the scripts folder in c:\windows\setup folder.

Also remember I said CASE is important. /ntfs/windows/setup/scripts is not the same as /ntfs/Windows/Setup/Scripts as it would be in the windows OS it self, you are still running linux here.

If you single step through a fog deploy like I posted and run into that error, press ctrl-C to blow out of the script. Then you can inspect the /ntfs path to ensure everything is as you would expect it. It helps with debugging greatly.

Don’t give up here, you are doing some pretty complex stuff with FOG, but will end up with a sweet solution when it all comes together.

[RobTitian16]

@george1421 Thanks, George. Definitely not going to give up here - if anything I’m actually craving more understanding of the coding, etc. which I’ll hopefully gain in time
So I’d have to create this folder structure inside the image first? Can I not do it through the script whilst it’s in FOS?

[george1421]

@RobTitian16 you can do anything structure wise in the post install script. So if you know that you need to create the scripts folder then just issue this command.
md /ntfs/Windows/Setup/Scripts just before the copy command. But again you need to know exactly what your target system has.

[george1421]

@RobTitian16 In my setup I will quick patch a target system between image captures. So if I need to update the unattend.xml between image captures or update the setupcomplete.cmd file I can do that via a post install script. Then the next time we capture the image we integrate the “patches” we’ve been doing in the post install script. It works out pretty well.

[RobTitian16]

@george1421 Thanks for the help so far
The SetupComplete.cmd doesn’t seem to be working still - when running it through an elevated command prompt, it says: “the installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor…”

[george1421]

@RobTitian16 OK wait, you are in the windows realm now? So FOS and linux has done its part !!

So the setup complete file IS making to the target computer now?

If so now you need to work in windows to understand what is not right.

How is the fog client msi getting to the windows box? Is the setup complete batch file referencing the full path to the msi?

[RobTitian16]

@george1421 Yep, sorry - I responded at 1am which is really not a good idea as I had no idea where I was or what I was doing.

I realised after your post I didn’t actually have a section that would copy across the FOG client msi to the Windows system. I tried to add a couple of lines that would copy across the FogService.zip from /root/trunk/packages/web/client and then unzip it, but it never worked when run (it always said it couldn’t unzip /ntfs/Windows/Setup/Scripts/FogService.zip [.zip]"

So, I’ve now unzipped the FogService.zip on the FOG server and try to copy across the “Fog Service Installer.msi”. However, this doesn’t appear to be working, either. Perhaps I’ve missed something? Or perhaps there’s an easier way to get the msi across to the target computer?

   # Check if the file FOG Service Installer.msi exists in the source folder and then copy it to the destination on the C: drive.
   if [ -f "/root/trunk/packages/web/client/FogService/Fog Service Installer.msi" ]; then
   	cp "/root/trunk/packages/web/client/FOGService/FOG Service Installer.msi" "/ntfs/Windows/Setup/Scripts/FOG Service Installer.msi";
   fi  

   # Check if the file SetupComplete.cmd exists in the source folder and then copy it to the destination on 
       # the C: drive. 

       if [ -f "/images/drivers/Common/SetupComplete.cmd" ]; then
           cp /images/drivers/Common/SetupComplete.cmd /ntfs/Windows/Setup/Scripts/SetupComplete.cmd;
   		# append the msiexec command to the end of the setupComplete.cmd file 
   		echo "msiexec.exe /i "FOG Service Installer.msi" /quiet USETRAY=\"0\" WEBADDRESS=\"${FOGIP}\" " >> /ntfs/Windows/Setup/Scripts/SetupComplete.cmd
   		# just in case we edited the setupcomplete.cmd file in unix lets filter it to make it DOS compatible
   		unix2dos /ntfs/Windows/Setup/Scripts/SetupComplete.cmd
       fi

@RobTitian16

You don’t need the ; at the end of the cp commands.

In fact, in your current structure you only need the ; after the if brackets because you have then on the same line.

I don’t know (and somewhat doubt) that that’s the issue, but doesn’t hurt to check.

Also, you don’t seem to check the existence of the /ntfs/Windows/Setup/Scripts folder before trying to copy there.

So do something like

if [ ! -d "/ntfs/Windows/Setup/Scripts" ]
then
  mkdir "/ntfs/Windows/Setup/Scripts"
fi

Before the other two if statements.

[RobTitian16]

@Quazz Thanks - will give this a go and see what happens.

[Quazz]

@RobTitian16 Thinking about it, Windows might sometimes create a scripts folder instead of a Scripts folder.

So we need to check for both.

#if scripts exists then by default Scripts does not, but if scripts does not exist then it's still possible Scripts doesn't either
if  [  -d "/ntfs/Windows/Setup/scripts" ] 
then
  mv "/ntfs/Windows/Setup/scripts" "/ntfs/Windows/Setup/Scripts"
else
  mkdir "/ntfs/Windows/Setup/Scripts"
fi

Since Windows doesn’t care about capitalization, you can safely rename it to a capitalized version. This will be overzealous with the mkdir, triggering in more cases than necessary, but since mkdir can’t do anything if the target exists, I don’t consider this to be problematic.

[RobTitian16]

@Quazz Unfortunately it’s still not copying the msi across.
I wonder if it’s because of the quotations and if it doesn’t like them there.

I’ve also noticed that with the following line, it doesn’t put “FOG Service Installer.msi” in quotes in the SetupComplete.cmd:

echo "msiexec.exe /i "FOG Service Installer.msi" /quiet USETRAY=\"0\" WEBADDRESS=\"${FOGIP}\" " >> /ntfs/Windows/Setup/Scripts/SetupComplete.cmd
