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.
