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
- nnslog ?-host host? ?-port port?
-
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- -host name|ipaddress
- 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.
- -port number
- 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.
