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¶
- 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.
