Hostname Changer No Reboot

[Wayne Workman]

It’s probably noteworthy to say that you should absolutely NOT take an image from computers that are bound to an Active Directory domain…

It’d probably screw up the hostname changing… and it’d definitely screw up the trust relationship between your DCs (domain controllers) and the deployed client images…

[Bruno Nogueira]

@Wayne-Workman We doesn’t have any image with Active Directory active, it is just normal Windows PCs

[Bruno Nogueira]

@Wayne-Workman Hi, I’ve done a new deploy and the hostname doesn’t change after imaging, but after it fog try to change it (* Changing hostname…Done) so it have to be something about the Windows Image that by some reason its not changing the registry.
What is the commands fog use to change it?
Can this happen because of permissions?
Thanks!!

@Bruno-Nogueira The only thing that I can think that is not allowing the hostname to change is your image is sysprepped, but setup for OOBE mode which requires the user to create a username and hostname.

[Bruno Nogueira]

Maybe I found part of my solution here:
https://forums.fogproject.org/topic/3361/early-hostname-change-not-working-win7/19

My image that change the hostname only have 1 partition (not counting with small windows partitions).

But the image that’s not changing the hostname have 2 partitions and maybe it is applying hostname configuration in the last partition (only data) and not on Windows partition.

I’ve tried to config my server with the steps in the link but my fog.download its a little diffrent and some commands like “xz --decompress init.xz” doesn’t work.

[Bruno Nogueira]

@Tom-Elliott My image is just a normal machine clone, ready to use but not OOBE (the first start is a normal windows startup with all users and everything on it).
Do you think that update to SVN fix the problem?

Please look at this thread: https://forums.fogproject.org/topic/3361/early-hostname-change-not-working-win7

That person was using FOG 1.1.2 (I imagine it’s probably fairly similar to 1.2.0). They reported that the early hostname changer only tried to change the name on the last partition restored.

How many partitions does your image have?

You said you were installing “TimeFreeze” or activating it or turning it on or something. If this is “hard drive locking” software, I have some experience with this. In the case of Centurion Technologies Smart Shield and Faronics DEEP FREEZE, both of these create a “unfrozen/unlocked” partition.

If this is the case with “TimeFreeze”, then this might be why you’re experiencing these issues with the early hostname changer…

Just a guess…

[Bruno Nogueira]

@Wayne-Workman Time Freeze is not installed, on first boot after imaging the computer run a script to install it. When the image is deployed time freeze is not there.
I’ve already seen that topic, the problem is the file initmountdir/bin/fog.download is not exactly the same as mine.
For example, in the line 268 I haven’t “elif [ “$imgType” == “mps” ]; then” and if I search for it I have 4 or 5 lines like this.
All of them doesn’t have the same sequence:

268 elif [ “$imgType” == “mps” ]; then
269 parts=fogpartinfo --list-parts $hd 2>/dev/null;
270 diskLength=expr length $hd;
271 for part in $parts; do
272 partNum=${part:$diskLength};
273 echo " * Processing Partition: $part ($partNum)";
274 sleep 2;
275 imgpart="$imagePath/d1p$partNum.img";
276 if [ ! -f $imgpart ]; then
277 echo " * Partition File Missing: $imgpart";
278 else
279 writeImageMultiCast $part
280 fi
281 changeHostname;
282 done

host_namechange_early functions by editing the registry of the computer offline
fog 1.2.0 assumed a specific partition would be used for the operating system and only tried to edit the registry there.
the latest development versions of fog attempt the edit on all ntfs partitions.
upgrading to trunk will almost certainly resolve your problem.

Hi again!
Today I’ve installed the most recent SVN version and the problem is now solved, thanks to all!
I’m impressed with the download speed of the images… 10GB /Min vs old 4 GB /Min!!
But now I have a problem (the only problem so far). I can’t edit groups, it returns error HTTP 500.

Please be more specific, exactly what were you editing with groups?

[Bruno Nogueira]

@Wayne-Workman In group management I have some groups with hosts inside.
Example, I have a group called “Group 1” with 10 members (hosts) and when I press edit it give error “HTTP 500”

[Tom Elliott]

Whenever you have a “Blank Page” or a 500 series error, it usually indicates an error of syntax, or some other issue. Can you go to the groups page while tailing the apache error logs and give us the output?

I’m just guessing but you have a bunch of groups?

To fix the memory issue: From the fog gui goto:

FOG Configuration Page->FOG Settings->General Settings->FOG_MEMORY_LIMIT

You’ll likely find that it’s currently set to 128. Increase this a big. I normally double, as needed. (E.G. 128->256, 256->512, 512-1024)

Don’t start High though as it impacts performance of the server the more you attempt to “add”

[Bruno Nogueira]

@Tom-Elliott I have 14 groups and 200 hosts
Now it is working!!! Thank you very much!! But it takes a little to open…
My server have an i5 intel processor and 4GB RAM
Can this be solved by adding more RAM?
Thanks!!!
EDIT: I think it only have 276MB free

I don’t think so… this memory limit specifies how much memory a page in fog can use (I think).

4 gigs of ram is probably excessive lol. I have my virtual fog machine set to 4 gigs and it’s only using 200 ish megs of that lol…

This command will display the amount of ram free, used, and such in MB format:
