Create Custom Fog Registration menu

2011-05-13T06:02:30Z

Ben:

In this example we will be using the Fog manual (Full Host Registration) process as a template, but slightly customizing it so that it only prompts for PC name Image ID and also automatically assigns the PC to the Windows 7 OS ID.

Firstly we will need to edit the Init.gz image ([[Modifying_the_Init_Image]])

open a terminal and enter the following

<nowiki>cd /tftpboot/fog/images
gunzip init.gz
mkdir initmountdir
mount -o loop init initmountdir</nowiki>

Navigate to /tftboot/fog/images/initmountdir/bin

Make a copy fog.man.reg

Rename the copy to fog.custom.reg

Open fog.custom.reg

Make the following changes (Red = Remove code, Blue = Add code)

''Lines 73-81''
host="";
ip="";
imageid="";
osid="NQ==";
primaryuser="";
other1="";
other2="";
blImage="";
blDoAD="";

(note "NQ==" is the number 5 'Windows 7' encoded in base64)

Delete the following code to remove the prompt for IP address

''Lines 88-91''
<pre style="color:red">
echo
echo -n " Enter the ip for this computer: ";
read ip;
ip=`echo $ip | base64`;
</pre>

Delete the following code to remove the prompt for OS ID

''Lines 109-123''
<pre style="color:red">
while [ "$osid" = "" ]
do
echo
echo -n " Enter the OS ID for this computer (? for listing): ";
....
....
osid=`echo $osid | base64`;
fi
done
</pre>

Delete the following code to remove the prompt for adding to Active directory

''Lines 125-140''
<pre style="color:red">
if [ "$blDoAD" = "" ]
then
echo
....
....
esac
fi
</pre>

Delete the following code to remove the prompts for Primary User, Tag 1 and Tag 2

''Lines 142-155''
<pre style="color:red">
echo
echo -n " Enter the primary user for this computer: ";
read primaryuser;
primaryuser=`echo $primaryuser | base64`;

echo
echo -n " Enter the other tag #1 for this computer: ";
read other1;
other1=`echo $other1 | base64`;

echo
echo -n " Enter the other tag #2 for this computer: ";
read other2;
other2=`echo $other2 | base64`;
</pre>

Make the following changes to so only the fields we have data for is sent back to the fog server

''Lines 202-204''

res=`wget -O - --post-data="mac=${mac}&advanced=1&host=${host}&ip=${ip}&imageid=${imageid}&osid=${osid}
&primaryuser=${primaryuser}&other1=${other1}&other2=${other2}&doimage=${realdoimage}&doad=${blDoAD}"

Now save this document as fog.custom.reg

Navigate to /tftboot/fog/images/initmountdir/etc/init.d

Open S99Fog and add the following lines

elif [ "$mode" == "clamav" ]; then
run="/bin/fog.av";
after=$afterActionTerm;
elif [ "$mode" == "customreg" ]; then
run="/bin/fog.custom.reg";
after=$afterActionTerm;
elif [ "$mode" == "autoreg" ]; then
run="/bin/fog.auto.reg";
after=$afterActionTerm;

Save this document

We now need to recreate the init.gz file with these new settings
open a terminal window and type
cd /tftpboot/fog/images
umount initmountdir/
rmdir initmountdir
gzip init

Finally we can add another menu option in the PXE boot menu so we can boot into our custom Registration process

navigate to /tftpboot/pxelinux.cfg

Open the file named default and add the following code (where you add this will depend on where in the menu you would like it to appear)

<pre style="color:blue">
LABEL fog.customreg
kernel fog/kernel/bzImage
append initrd=fog/images/init.gz root=/dev/ram0 rw ramdisk_size=127000 ip=dhcp dns=*.*.*.* mode=customreg web=*.*.*.*/fog/ quiet
MENU LABEL Custom Host Registration and Inventory
</pre>
NOTE the * should be replaced with your DNS and Fog Server IP addresses (check what the fog.reg and fog.reginput entries are and use the same)

Thats it. Now when you boot your PC your PXE menu should have a new menu option called "Custom Host Registration"
If you select this option you will go through the Fog registration and you will only be prompted for the PC name, The Image ID and whether or not you want to image the PC Now, by default the PC will have the Windows 7 OS ID

Ben: /* Modify your default file from your server */

==How to change the font size / color of the PXE boot menu==

It's very easy to edit the graphical pxe menu of the FOG server. You can change everything from the background color [[Link title]] to the font color / size, and even add additional pieces of software you can boot from.

===Modify your default file from your server===
You can also edit and modify the default menu file directly on your FOG server. This file is located in the '''/tftpboot/pxelinux.cfg''' folder. 
::''Note that this file, along with your customized edits, will be overwritten by FOG if the PXE boot menu is updated through the web interface.''

Open the default file in your favorite text editor. You are going to want to modify the file to adjust the menu color title and the default font color. Please note that font color and menu color are controlled similar to what you would see in HTML based coding.

<pre> DEFAULT vesamenu.c32
MENU TITLE FOG Computer Cloning Solution
MENU BACKGROUND fog/bg.png
MENU MASTER PASSWD $1$K8Vl0MRF$IeRczmyo1X3EH3Zf5aEcH0

menu color title 1;36;44 #ffffffff #00000000 std</pre>

By default #ffffffff = white

By default #00000000 = black

If you feel inclined, you can also change what is displayed at the top of the menu as well. Even though FOG is registered under GPL 3, I am going to suggest that you include some credit for Chuck Syperski / etc.

Here is a list of other color elements you may wish to change

screen Rest of the screen
border Border area
title Title bar
unsel Unselected menu item
hotkey Unselected hotkey
sel Selection bar
hotsel Selected hotkey
disabled Disabled menu item
scrollbar Scroll bar
tabmsg Press [Tab] message
cmdmark Command line marker
cmdline Command line
pwdborder Password box border
pwdheader Password box header
pwdentry Password box contents
timeout_msg Timeout message
timeout Timeout counter
help Help text
msgXX Message (F-key) file attribute XX

e.g
menu color unsel 1;36;44 #fc0000 #00000000 std
will change the color of your menu items to red
