NAME

nws_nameserver - nameserver for the Network Weather Service

 

SYNOPSIS

nws_nameserver [-a addresses][-n name][-D][-e file][-l file][-i file][-m][-N nameserver][-f file][-p port]

 

DESCRIPTION

This manual page explains the nws_nameserver program. Other NWS hosts ( nws_sensor(1),nws_memory(1) ) register their locations and attributes with a nws_nameserver. We recommend that NWS users run their own nws_nameserver.

NWS registrations follow the LDAP model. Each registered object consists of a set of attributes that are described by name-value pairs. Every object has a name attribute that identifies the object (this attribute should be unique) and an objectclass attribute that specifies what sort of item the object represents.

Here are some of the attributes you can find (see nws_search(1) on how to query a nws_namserver. Typically objects have some of the following attributes (in addition to name and objectclass):

timestamp

is the expiration time of the object: it won't show up past this time, unless the object is re-registered.

host

machine which hosts the daemons in name:port format

memory

nws_memory which holds the measurements related to this object

hostType

kind of NWS process (for example nws_nameserver, nws_memory or sensor)

ipAddress

list of IP addresses associated with this host that are available to NWS

owner

login of the person who started this NWS host

port

port which the host is listening to

 

OPTIONS

-a addresses

Specified a comma separated list of addresses (IPs or name) that the sensor will consider be aliases for the localhost. Used for multihomed machine when DNS doesn't return all the IPs associated with a name.

-n name

Use name as hostname. Useful the resolver aren't correctly configured and gethostname doesn't return a resonable value.

-e file

Save the error messages to file.

-l file

Save the log messages to file.

-i file

Write the pid to file

-m

Enable mirroring code: if we got a nameserver in our registration we try to sync with it and keep our registration synchronized. See -N.

-N nameserver

Try to read all the registrations from nameserver and add to our pool of registrations. If used with -m try to keep the nameservers in sync.

-f file

Save the registrations to file. Remember that file whenever a new version of registration is written. The deafult filename is registrations.

-p port Listen to port instead of the default for the nws_nameserver (8090).

 

BUGS

This man page doesn't explain all the possible options that the nws_nameserver will obey.

NWS is an original idea of Rich Wolski (rich@cs.ucsb.edu). The nws_nameserver is been introduced by Jim Hayes (jhayes@cs.ucsd.edu) and is been almost entirely rewritten by Graziano Obertelli (graziano@cs.ucsb.edu) who currently maintains NWS.
