Name service facility, Commandline Server Application


nnsd ?-localonly flag? ?-port port?


Please read Name service facility, introduction first.

The application described by this document, nns, is a simple command line server for the nano name service facility provided by the Tcllib packages nameserv, and nameserv::server. Beyond that the application's sources also serve as an example of how to use the server package nameserv::server.

This name service facility has nothing to do with the Internet's Domain Name System, otherwise known as DNS. If the reader is looking for a package dealing with that please see either of the packages dns and resolv, both found in Tcllib too.

Use Cases

nnsd was written with the following main use case in mind.


Run a nano name service on some host.

Command Line

nnsd ?-localonly flag? ?-port port?

The command configures a server per the specified options and starts it. The command will not exit on its own, as it keeps the name service database wholly in memory. The user has to kill it explicitly, either by sending a a signal, or through the job-control facilities of the shell in use.

The options to configure the name service are explained in section Options.


This section describes all the options available to the user of the application

-localonly bool

If this option is not specified it defaults to true, i.e. acceptance of only local connections. The server will accept remote connections, i.e. connections from other hosts, if and only if this option is configured to false.

-port number

If this option is not specified it defaults to 38573. It specifies the TCP port the server has to listen on for requests.
