GNUveau Networks builds solar-powered Linux computer networks for remote villages (vi
11-04-2008 12:00 PM
Scott Johnson of GNUveau Networks has developed a solar-powered Internet "hub" system (running Ubuntu GNU/Linux) that he builds to order in his Daytona Beach, Florida, home. His objective is to bring computers and the Internet to places that have no connectivity, no phone service, and no electricity. This is no pipe dream. There are real SolarNetOne installations running in Africa right now, providing wireless connectivity and "Internet Cafe" access to hundreds of people. The system uses off-the-shelf hardware that Scott modifies to run on 12V -- and to use a lot less power than the stock versions. As Scott says, in solar-powered computer installations, "The Watt is king."

NETWORKS(5)                                                 Linux System Administration                                                NETWORKS(5)

NAME

       networks - network name information

DESCRIPTION

       The  file  /etc/networks is a plain ASCII file that describes known DARPA networks and symbolic names for these networks.  Each line repre-
       sents a network and has the following structure:

              name number aliases ...

       where the fields are delimited by spaces or tabs.  Empty lines are ignored.  The hash character (#) indicates the start of a comment:  this
       character, and the remaining characters up to the end of the current line, are ignored by library functions that process the file.

       The field descriptions are:

       name   The  symbolic name for the network.  Network names can contain any printable characters except white-space characters or the comment
              character.

       number The official number for this network in numbers-and-dots notation (see inet(3)).  The trailing ".0" (for the host component  of  the
              network address) may be omitted.

       aliases
              Optional aliases for the network.

       This  file is read by the route(8) and netstat(8) utilities.  Only Class A, B or C networks are supported, partitioned networks (i.e., net-
       work/26 or network/28) are not supported by this facility.

FILES

       /etc/networks
              The networks definition file.

SEE ALSO

       getnetbyaddr(3), getnetbyname(3), getnetent(3), netstat(8), route(8)
