How to use Builder to create a Node

This page is intended to formalize how to use the current Builder scripts in the PTP subversion repository

( )

to build a Captive Portal Personal Telco Branded router on a computer with two ethernet cards.

The current state of builder is a working proof of concept. In the future all of the fuctionality of these process will be part of Adhocracy.

Step One (Prepare the Hardware)

For a matter of maintaining support and stability in a rational way we have choosen to use Debian Woody (Stable) as the Linux distribution to build upon. These scripts expect to find a computer that has a minimal debian install, two ethernet cards, and a connection to the Internet.

partition the hard disk

Currently the most common hard drive size that we have been using is a 2G drive. Normally this is the way the partitions are created.

256M Swap

256M /

512M /var

1G /home

install Debian Woody

Perform a minimal stable install easily accomplished with a Debian Stable r3 or r2 netinst disk.

Install with a 2.4 kernel

boot: bf2.4

Do not run taskel

Do not run dselect

Upon reboot, only create the root user, tell the mail subsystem to do nothing, enable all choices for encrypting passwords, and answer the default for most other questions (More detail later)

Do not run taskel

Do not run dselect

Step Two (Create Nodedb Entry)

Go to

Create an entry in nodedb which contains the details of the node location. Please use the naming scheme

'Personal Telco - Node Name'

Could this be expanded to Personal Telco - Quadrant - Neighborhood - Node Name ?

e.g. Personal Telco - NE - Kerns - Urban Grind

Document the Node number which was assigned to the location.

Step Three (Create Configuration Files)

Define Network Address Allocation

Go to the wiki page NetworkAddressAllocations and define the network that will be used for the node.

Please use network allocations that are efficient for the network you are installing

ie. You probably don't need to use a full /24

Create files with

Create a working directory to run the builder script

mkdir builder

cd builder


chmod 755

Now run with the -s option

./ -s

and complete the following questions in a way that is applicable to your node location:

[aaronb@laptop builder]$ ./ -s

Node number: 608

Location (20 char. or less): Urban Grind - Pearl District


Hostname: grank



Internet IP address (or 'dhcp'): dhcp

Internet DNS address 1:

Internet DNS address 2 (or 'none'):

PTPnet IP address:

PTPnet network address:

PTPnet network mask:

PTPnet broadcast address:

PTPnet DHCP server pool start address:

PTPnet DHCP server pool finish address:

This will create and commit the configuration files for your node into the repository
