SysConfig - Relocated Variables

Almost all rc.config variables have been moved to the /etc/sysconfig hierarchy. However, several variables cannot be found in the mentioned files. Things changed after the manual went to press. (This started with version 8.0)

If you cannot find a specific variable (e.g., KBD_NUMLOCK), search for the right file with the command:

find /etc/sysconfig -type f | xargs grep KBD_NUMLOCK

If you do not find anything, try with a substring. For example, instead of POSTFIX_NULLCLIENT use only:

find /etc/sysconfig -type f | xargs grep NULL

VMware Config Notes

    When setting up your configuration exercise caution when answering the questions. One of the questions:

Do you want this script to automatically configure your system to allow your
Virtual Machines to access the host's filesystem? (yes/no/help) [no]

If you are already using Samba in Linux, then the answer to this question is NO. If you answer yes, then it will setup a VMware version of Samba and there will be a conflict. Also, when you set up the Networking in your Windows section, do not use anything Windows oriented.

    The other questions involve Host-only and Bridged Networking.

Bridged networking

  • The Host acts like a network bridge.
  • Virtual networking that allows the Guest operating system direct access to the local LAN via the host.
  • Allows the LAN to directly access the Guest.
  • Up to 3 bridged networks can exist per Guest and Host.
    Bridged networking means a virtual machine runs on a virtual network that is "bridged" to an existing physical network. This permits a virtual machine to appear as a full-fledged host on an existing physical network.
    Bridged networking connects a virtual machine to a network using the host computer's Ethernet adapter. If your host computer is on an Ethernet network, this is often the easiest way to give your virtual machine access to that network. If you use bridged networking, your virtual machine needs to have its own identity on the network. For example, on a TCP/IP network, the virtual machine needs its own IP address. I use Dusty-tr as the hostname for my main Linux machine and Dusty2 for the Windows virtual machine inside Linux. The numeric IP addresses for these hosts are obtained thru DHCP. If you are using static IP addresses then you could use, for example, for the main host and for the virtual machine. Or whatever IP's your administrator assigned to your system(s).

    A bridged virtual machine may transparently use any of the services available on the network that it is bridged to: printers, file servers, gateways, etc. Likewise, when a virtual machine is bridged, any physical host -- or other virtual machine configured as bridged -- can use resources on that virtual machine. This is the most commonly used networking configuration.

    If you use bridged networking, the virtual machine is a full participant in the network. It has access to other machines on the network and can be contacted by other machines on the network as if it were a physical computer on the network. As I've stated elsewhere, it is one of the ways I check out some my Networking using only one machine. Each virtual machine must have its own IP address. Which is separate and different from the host machine it is installed on.

Host-only networking

    Host-only networking creates a network that is completely contained within the host computer. Host-only networking provides a network connection between the virtual machine and the host computer, using a virtual Ethernet adapter that is visible to the host operating system. This approach can be useful if you need to set up an isolated virtual network.

    If you use host-only networking, your virtual machine and the host virtual adapter are connected to a private TCP/IP network. Addresses on this network are provided by the VMware DHCP server.

    In my Network setup I am using both the Host-only and Bridged Networking.
