This is to announce the availability of xnetdb version 2.02 (the current
version being 2.01). Major improvements/additions from v2.01 -> v2.02
include:
* assorted bugs fixed
* support for hosts has been added
* a graphical traceroute function has been added
Xnetdb may be obtained via anonymous ftp from thor.oar.net (131.187.1.135)
in the /pub directory. I've included a bit of the man page below.
I'm also in the process of setting up a mailing list for those interested
in using xnetdb. Drop a note to me (henryc@oar.net) and you'll get added.

DESCRIPTION
Xnetdb is a network monitoring tool based on X Windows and
SNMP which also has integrated database and statistic view-
ing capabilities. Xnetdb will determine and display the
status of routers and circuits it has been told to monitor
by querying the designated sites and displaying the result.
Additionally, it also has integrated database functionality
in that it can display additional information about a site
or circuit such as the equipment at the site, the contact
person(s) for the site, and other useful information.
Finally it can gather designated statistical information
about a circuit or router and display it on demand.
OPTIONS
-v This enables the verbose mode of xnetdb. This is
useful only when used with the -monitor option.
-monitor This enables the monitor mode of xnetdb in which
it will actively query routers to determine their
status and update the map to reflect that status.
The default is not to monitor so that unecessary
SNMP traffic is avoided.
-display host
This will display the xnetdb map on the host
specified.
-cpath path
This gives the path in which it will find all of
the xnetdb configuration files. Note that this
defaults to the setting in the xnetdb.h file set
at compilation.
USING XNETDB
Invoking any of the database or statistics functions is
merely a function of pressing the left mouse button on the
proper item and selecting the choice of interest from the
menu. For example, to invoke the router menu, move the
pointer on top of the router you desire more information
about and the press the left mouse button, to invoke the
circuit menu press the left mouse button on top of a cir-
cuit, and to invoke the summary/stats menu to press the left
mouse button anywhere else. To quit xnetdb, press "q"
within the xnetdb window.
CONFIGURATION FILE
The configuration file xnetdb.cf specifies all of the things
that you want xnetdb to monitor and/or keep information
about. There are three types of things which can be
configured into the file - routers, hosts, and variables.
ROUTER <path> <routername> <mapname> <ipaddress> <community>
The <path> entry specifies the path into the database
where xnetdb can find information about the router. The
<routername> entry specifies the name of the router in
the database. The <mapname> entry specifies the name
which will be displayed on the xnetdb map. The <ipad-
dress> entry specifies the ip address of the router.
Finally, the <community> entry specifies the SNMP commun-
ity name to use when querying the router.
HOST <path> <hostname> <mapname> <ipaddress> <community>
The <path> entry specifies the path into the database
where xnetdb can find information about the host. The
<hostname> entry specifies the name of the host in the
database. The <mapname> entry specifies the name which
will be displayed on the xnetdb map. The <ipaddress>
entry specifies the ip address of the host. Finally, the
<community> entry specifies the SNMP community name to
use when querying the host.
VARIABLE <rtraddr> <variable> <variabletype> <community>
The <rtraddr> entry is the ip address of the router. The
<variable> entry is the name of the snmp variable you
wish to monitor. The <variabletype> entry is the type of
the variable that the agent will return (such as Integer,
IPAddr, etc.). Finally, the <community> entry specifies
the SNMP community name to use when querying the entity.
