10.1 Utilizing The Configure-Hubmaster Script
Use the following procedure to invoke the configure-hubmaster script:
• Login locally to the target node as operator
• Type “sudo /usr/sbin/configure-hubmaster” and enter the password when prompted.
• Enter the information as shown in the following paragraphs.
10.1.1 IP Address / Netmask
At the IP prompt, enter the static IP address that has been assigned to this Hub Master node.
This is a crucial step, as it not only defines the node’s identity, but, in conjunction with the
netmask input, it also defines the subnet it services. It is advised that the node IP be in the form
XXX.YYY.ZZZ.1, to match the default Digivance CXD DHCP settings. The netmask prompt
further defines which subnet the Hub Master node will service. The default is 255.255.255.0,
or a “class C netmask”. This is the recommended netmask value for the Digivance CXD
system.
10.1.2 DHCP Address Range
The DHCP address range portion of the script first prompts the operator for the beginning of
the range. It uses the IP address and netmask input described previously to provide a default
lower limit of XXX.YYY.ZZZ.3. When in doubt, depress the enter key to select the default
lower limit. Likewise, a default upper limit will be generated, servicing nodes up to and
including XXX.YYY.ZZZ.250. Again, unless a different upper limit is desired, simply press
the enter key to use the default value. For examples involving changing these limits, see
Section 10.2.2
10.1.3 Default Gateway / Router
At the prompt, enter the IP address of the router interfacing with the node being configured. If
there is to be no upstream router, enter in the IP address of the Hub Master node itself. Failure
to enter a valid IP address in this field will result in the improper network operation of the
Digivance CXD System.
10.1.4 Hub Master Domain
Each Hub Master node requires its own domain to service. This is to allow multiple Hub
Master nodes to use the same upstream DNS, and also negates the problem where slave nodes
try to talk to the “wrong” Hub Master. The default value is Digivance CXD, which is
suggested to be changed to something more descriptive in the target network. At a minimum,
numbering the domains serially will achieve the desired result (i.e. Digivance CXD, Digivance
CXD-4XD-G22, etc.).
