          NAME
               DiG

          KEYWORDS
               status; DNS; spoof; UNIX; free.

          ABSTRACT
               DiG (domain information groper), is a command line tool
               which queries DNS servers in either an interactive or a
               batch mode.  It was developed to be more
               convenient/flexible than nslookup for gathering perfor-
               mance data and testing DNS servers.

          MECHANISM
               Dig is built on a slightly modified version of the bind
               resolver (release 4.8).

          CAVEATS
               none.

          BUGS
               None known.

          LIMITATIONS
               None reported.

          HARDWARE REQUIRED
               No restrictions.

          SOFTWARE REQUIRED
               BSD UNIX.

          AVAILABILITY
               DiG is available via anonymous FTP from venera.isi.edu
               in pub/dig.1.0.tar.Z.

          Internet Tool Catalog                           DUAL MANAGER


          NAME
               Dual Manager

          KEYWORDS
               alarm, control, manager, map, security, status; IP,
               OSI; NMS, SNMP, X; UNIX; library.

          ABSTRACT
               Netlabs' Dual Manager provides management of TCP/IP
               networks using both SNMP and CMOT protocols.  Such
               management can be initiated either through the X-
               Windows user interface (both Motif and Openlook), or
               through OSI Network Management (CMIP) commands.  The
               Dual Manager provides for configuration, fault, secu-
               rity and performance management.  It provides extensive
               map management features, including scanned maps in the
               background.  It provides simple mechanisms to extend
               the MIB and assign specific lists of objects to
               specific network elements, thereby providing for the
               management of all vendors' specific MIB extensions.  It
               provides an optional relational DBMS for storing and
               retrieving MIB and alarm information.  Finally, the
               Dual Manager is an open platform, in that it provides
               several Application Programming Interfaces (APIs) for
               users to extend the functionality of the Dual Manager.

               The Dual Manager is expected to work as a TCP/IP
               "branch manager" under DEC's EMA, AT&T's UNMA and other
               OSI-conformant enterprise management architectures.

          MECHANISM
               The Netlabs Dual Manager supports the control and moni-
               toring of network resources by use of both CMOT and
               SNMP message exchanges.

          CAVEATS
               None.

          BUGS
               None known.

          LIMITATIONS
               None reported.

          HARDWARE REQUIRED
               Runs on Sun/3 and Sun/4s.

          Internet Tool Catalog                                   ENTM


          NAME
               ENTM -- Ethernet Traffic Monitor

          KEYWORDS
               traffic; ethernet, IP; eavesdrop; VMS; free.

          ABSTRACT
               ENTM is a screen-oriented utility that runs under
               VAX/VMS.  It monitors local ethernet traffic and
               displays either a real time or cumulative, histogram
               showing a percent breakdown of traffic by ethernet pro-
               tocol type.  The information in the display can be
               reported based on packet count or byte count.  The per-
               cent of broadcast, multicast and approximate lost pack-
               ets is reported as well.  The screen display is updated
               every three seconds.  Additionally, a real time, slid-
               ing history window may be displayed showing ethernet
               traffic patterns for the last five minutes.

               ENTM can also report IP traffic statistics by packet
               count or byte count.  The IP histograms reflect infor-
               mation collected at the TCP and UDP port level, includ-
               ing ICMP type/code combinations.  Both the ethernet and
               IP histograms may be sorted by ASCII protocol/port name
               or by percent-value.  All screen displays can be saved
               in a file for printing later.

          MECHANISM
               This utility simply places the ethernet controller in
               promiscuous mode and monitors the local area network
               traffic.  It preallocates 10 receive buffers and
               attempts to keep 22 reads pending on the ethernet dev-
               ice.

          CAVEATS
               Placing the ethernet controller in promiscuous mode may
               severly slow down a VAX system.  Depending on the speed
               of the VAX system and the amount of traffic on the  lo-
               cal  ethernet,  a large amount of CPU time may be spent
               on the Interrupt Stack.  Running this code on any  pro-
               duction system during operational hours is discouraged.

          BUGS
               Due to a bug in the VAX/VMS ethernet/802 device driver,
               IEEE  802 format packets may not always be detected.  A
               simple test is performed to "guess" which  packets  are
               in  IEEE  802  format (DSAP equal to SSAP).  Thus, some
               DSAP/SSAP pairs may be reported as  an  ethernet  type,
               while  valid ethernet types may be reported as IEEE 802
               packets.

               In some hardware configurations, placing an ethernet
               controller in promiscuous mode with automatic-restart
               enabled will hang the controller.  Our VAX 8650 hangs
               running this code, while our uVAX IIs and uVAX IIIs do
               not.

          LIMITATIONS
               The user is required to have PHY_IO, TMPMBX and NETMBX
               privileges.  When activated, the program first checks
               that the user process as enough quotas remaining
               (BYTLM, BIOLM, ASTLM and PAGFLQUO) to successfully run
               the program without entering into an involuntary wait
               state.  Some quotas require a fairly generous setting.

               The contents of IEEE 802 packets are not examined.
               Only the presence of IEEE 802 packets on the wire is
               reported.

               The count of lost packets is approximated.  If, after
               each read completes on the ethernet device, the utility
               detects that it has no reads pending on that device,
               the lost packet counter is incremented by one.

               When the total number of bytes processed exceeds
               7fffffff hex, all counters are automatically reset to
               zero.

          HARDWARE REQUIRED
               A DEC ethernet controller.

          Internet Tool Catalog                              ETHERFIND


          NAME
               etherfind

          KEYWORDS
               traffic; ethernet, IP, NFS; eavesdrop; UNIX.

          ABSTRACT
               Etherfind examines the packets that traverse a network
               interface, and outputs a text file describing the
               traffic.  In the file, a single line of text describes
               a single packet: it contains values such as protocol
               type, length, source, and destination.  Etherfind can
               print out all packet traffic on the ethernet, or
               traffic for the local host.  Further packet filtering
               can be done on the basis of protocol:
