nnslog(n)nnslog(n)______________________________________________________________________________NAMEnnslog - Name service facility, Commandline Logging Client Application
SYNOPSISnnslog ?-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 dif‐
ferent 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 ser‐
vice 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 speci‐
fies the TCP port the name service to talk to is listening on
for requests.
