nnslog(n) Name service facility nnslog(n) 





NAME


nnslog - Name service facility, Commandline Logging Client
    Application






SYNOPSIS


nnslog ?-host host? ?-port
    port?










DESCRIPTION


Please read Name service facility, introduction first.


The application described by this document, nnslog, is a
    simple command line client for the nano name service facility provided by
    the Tcllib packages nameserv, and nameserv::server.


It essentially implements "nns search -continuous
    *", but uses a different output formatting. Instead of continuously
    showing the current contents of the server in the terminal it simply logs
    all received add/remove events to stdout.


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


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



  
[1]

  
Monitoring the name service for all changes and logging them in a text
      terminal.








COMMAND LINE



  

  
The command connects to the specified name service, sets up a search for
      all changes and then prints all received events to stdout, with each
      events on its own line. The command will not exit until it is explicitly
      terminated by the user. It will especially survive the loss of the
      connection to the name service and reestablish the search and log when the
      connection is restored.
    
The options to specify the name service will be explained
        later, in section OPTIONS.

  








OPTIONS


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



  

  
If this option is not specified it defaults to localhost. It
      specifies the name or ip-address of the host the name service to talk to
      is running on.

  

  
If this option is not specified it defaults to 38573. It specifies
      the TCP port the name service to talk to is listening on for
    requests.
