In most versions of FOG (including 1.2.0 and 1.3.0), the low-level settings that are used during installation and some settings that simply cannot be stored in the database are contained in the /opt/fog/.fogsettings file.

This file contains the setup of variables used within the installer during upgrades/installs.

Header/Footer

Header

Only gives some simplistic information to help users. Does no actions just gives some information.

## Start of FOG Settings
## Created by the FOG Installer
## Version: 7625
## Install time: Sat 14 May 2016 08:05:18 PM EDT

Footer

Does no actions, just tells where FOG's default variables are setup Any new items will go below this, and you can add your own variables. You can add variables wherever you want.

## End of FOG Settings

IP Address

Defines the IP address of the node/server. This is also used on servers to setup the default.ipxe file.

ipaddress='192.168.1.5'

Interface

This just sets the storage nodes/server interface as it will be stored in the Database. This used to be used for multicast setups and for the bandwidth graph. This is now setup so it is only used on the bandwidth graph as we already know the ip address anyway. Multicast tasks can get their own interface instead of relying on user entry.

interface='eth0'

Subnet Mask

This defines the subnet mask to use if the system is to be used as a DHCP server. It will assume the subnet mask of the interface being used, but can be changed later if you see fit.

submask='255.255.255.0'

Router Address

This will setup the router address to use if the system is to be used as a DHCP server. It currently only sets as an ip address, but in the past contained the whole dhcp configuration string. The config string was removed as it would only work on isc-dhcp-server, when some might be using dnsmasq or another dhcp server.

routeraddress='192.168.1.1'

Plain Router

Very similar to the Router Address elements above, but can be used to redirect to maybe another router/switch other than the main.

plainrouter='192.168.1.1'

DNS Address

dnsaddress

Used, again, for DHCP setup.

dnsaddress='192.168.1.5'

dnsbootimage

No longer used. It's purpose was originally because the FOS (Fog Operating System -- init.xz/init_32.xz/init.gz) did not dynamically get the dns address from DHCP as dhcp was not called.

dnsbootimage='192.168.1.5'

Linux Login/FTP

Username

This variable is the user setup for the linux user on the server. This allows a user to login to the server/node under this username through linux. The purpose of this is more specifically setup for FTP usage.

username='fog'

Password

This is the linux fog user password. It is randomly generated if the value is not already defined. Every update will reset the password to what is in this field. You should, if you predefined a fog user and the installation is the first time, create the /opt/fog/.fogsettings file. Only add the password field to ensure your password doesn't get changed accidentally.

password='Some!random_Password\here0918358'

OS Information

OS Identifier

This is the OS identifier used during the installation. The value is numeric.

Valid Values are:

Redhat based.
Debian based.
Arch

osid='2'

OS Name

This is the name of the OS as it's being installed.

osname='Debian'

DHCP

dodhcp

Just tells if we want fog to install dhcp.

dodhcp='N'

bldhcp

Same, more or less, as dodhcp

bldhcp='0'

dhcpd

Defines what package to install for dhcp server.

dhcpd='isc-dhcp-server'

NFS

Defines if the installer should rebuild the exports every time. Setting to 0 will ensure the exports file for nfs does not get rebuilt. Setting to 1 will update the exports file.

blexports='1'

Type of installation

Just tells the installer if this is going to be a full server, or a node. If it's a node, the value will be S. If it's a full server, the value will be N.

installtype='N'

Database Information

MySQL User

This is the username to connect to the database as. Blank will default to connecting as user root.

snmysqluser=''

MySQL Password

This is the password to connect to the database.

snmysqlpass=''

MySQL Host

This is the host to connect to the database. Blank will default to localhost/127.0.0.1.

snmysqlhost=''
