Configuring a node

Compact flash nodes and CD-ROM nodes with a floppy drive installed can be configured via a web-interface and clicking on "Config".

Configurable values are:

channel

This can be any valid channel for the protocol being used. For 802.11b this is any integer between 1 and 11. Every node in a given mesh must be on the same channel.

wired interface

This can be set to "auto", "dhcpd", or "dhclient". Depending on the setting the node will either act as a DHCP client or a DHCP server. If it is a DHCP client then it will act as an "internet connected node". The default is "auto".

hostname

This is the name by which this host identifies itself.

latitude, longitude

The latitude and longitude for use by the visualization engine. Do not set these unless you have also custom configured RouteViz with a local map and it's latitude and longitude corners.

nameservers

A comma separated list of nameservers that will be used locally and given out to DHCP clients to use for their lookups. You should choose something local to your ISP or a public DNS server.

ssid

A unique identifier for the whole mesh cloud, this must be the same one all machines that wish to be part of the mesh.

Configuring a node creates the file /etc/cuw_config on a node. That file which is simply a flat file containing variable assignments. You can untar an upgrade image, replace it's cuw_config file, then retar it and then apply it as an upgrade. This is an easy way to create a localized distribution from the standard builds.
