Fog login screen

Preparing the Master Client host

Windows XP

Install Windows XP service Pack 2 support tools and if using the 'danish edition of Windows XP edit C:\Program files\FOG\etc\config.ini line with the path to netdom.exe from C:\Program files\Support tools\netdom.exe to C:\Programmer\Support tools\netdom.exe

Install fog client http://192.168.22.3/fog/client program. (Note below Danish version of XP)

Issues

With FOX Service Installer (FOX Tray version 0.1) The installer installs in C:\Program files\FOX but looks for the FoxServiceConfig.exe in C:\programmer\FOX in the danish version of XP.

Windows 2003

Fog service

After installing the support tool you need to install the fog service

Go to http://FogServerNameOrIP/fog/client webpage

Files

Installed version 0.28 (Same procedure)

  • logfiles: /opt/fog/log
  • basic Configfile: /opt/fog/service/etc/config.php
  • www installation: /var/www/html/fog

/opt/fog/service/etc/config.php

  • UDPSENDER_MAXWAIT: default null wait forever on all multicast members. Set to seconds to abandom stucked hosts.

DHCP on another server

  • On a Linux DHCP server you must set: next-server
  • On a Windows DHCP server you must set: option 066 & 067

Known issues

Uploading images with NTFS (XP) to machines which had a linux EXT3 filesystem (CentOS 5.2) gave problems. The Restore process on the client never started. It just bootet from the server saying "Please Wait" on the blue screen - then jumped direcly to Cleanup.

After running Fast-Wipe on the machines, everything was OK.

Customization

ESXi installer

To enable the functionality to install ESXi from the FOG server we need to add the ESXi install image and create a new menu in the FOG install menu.

TFTP files needed for installation

From the VMWare ESXi install iso extract these files into an tftp folder: 

cim.vgz
ienviron.vgz
install.vgz
mboot.c32
menu.c32
sys.vgz
vmkboot.gz
vmkernel.gz

In the FOG installation its called /tftboot/ESXi/

NFS files needed for installation

Create a place where the installation can access the rest of the files from the install iso. In this installation its located at /tftpboot/ESXi/iso/. Copy the files from the iso to this folder and export it via nfs:

/etc/exports: 

# Install folder for ESXi
/tftpboot/ESXi/iso             *(rw,sync,no_wdelay,no_root_squash,insecure)

pxelinux.cfg/default

Add this enty to the default pxe file: 

LABEL esx.install
	kernel ESXi/mboot.c32
	append ESXi/vmkboot.gz ks=http://fog.tekkom.dk/kickstart/ESXi.ks --- ESXi/vmkernel.gz --- ESXi/sys.vgz --- ESXi/cim.vgz --- ESXi/ienviron.vgz --- ESXi/install.vgz
	MENU LABEL Install VMWare ESXi 4.1
	TEXT HELP
	This will install VMware ESXi 4.1 and wipe the HDD.
	Default password = Password
	ENDTEXT
\n

Kickstart file

The kickstart file is located on a web server and contains the installation notes.

/var/www/html/kickstart/ESXi.ks:
