   Special Mini-Presentation:
     Topic:    Promiscuous Monitoring with "ifchk"
     Speaker:  Josh Birnbaum of Noorg, Inc.


   Mini-Presentation Introduction:

   One of our Unigroup members, Josh Birnbaum of Noorg, Inc., has
   developed an Open Source Project called "ifchk", which is a tool
   which provides Host Based Promiscuous Mode Detection.  See:

   Josh will give us a short mini-presentation on "ifchk", prior to
   our main IPv6 presentation.

   Here is an outline from Josh:

   I'll begin with a description of what it actually is for a network
   interface to operate in promiscuous mode.  This would be within the
   context of Ethernet.  I'd start with the reception of Ethernet frames
   off of the wire by the network hardware and go through the trip up
   the protocol stack that the frame takes, depending whether the
   interface is in the promiscuous state or not.  This would be within
   the context of the network hardware, device driver interaction and
   the protocol stack.

   Next, I'd provide scenarios where packet sniffing can be used by the
   sysadmin to solve system/network related problems.  Network latency
   comes to mind as a good application of packet capture as does it's
   use in tracking down problems with network services.  E.G. My client
   side NFS mounts are taking forever or failing... Why?  I'd then talk
   about how it can be used for not so honorable ends (sniffing
   passwords, etc).  It is here that I'd discuss ifchk and how the tool
   can be used by sysadmins to detect and counter this abuse in real
   time, and how ifchk can provide accurate network traffic analysis on
   a per-interface basis for reference in either good times or
   (suspected) bad.  I'd also like to mention some ifchk internals
   stuff (ioctl(), etc), time permitting.


   Main Presentation Introduction:

   Note: Unigroup's previous meeting on IPv6 was in January 1996, and
   given the [slow] adoption rate of IPv6, we were clearly ahead of
   the curve back then.  These days, IPv6 is more of a reality as it
   ships with many major Unix/BSD/Linux operating systems.

   Internet Protocol version 6 (IPv6) was first introduced in December
   1995, when several RFCs were completed by the IP Next Generation
   (IPNG) working group of the Internet Engineering Task Force (IETF).
   Since then, many of the RFCs have been revised and updated.
   Primarily intended to alleviate the perceived IP address exhaustion
   issues that were facing the IPv4 community, IPv6 includes many other
   features that are expected to improve the operation of IP networks.
   These features include better security, performance, mobility, and

   The deployment of IPv6 is expected to be gradual, and coexistence
   with IPv4 networks is inevitable for years to come.  The transition
   to IPv6 will be evolutionary, and the tools available to assist in
   this migration will be critical for worldwide adoption of the next
   generation of IP.  Many of the advantages of IPv6 are designed for
   ease of use by end users, but network administrators will require
   even more sophisticated tools to operate and support these networks. 



   * Keep an eye out on the deadline date and time, as it may change.

   Please RSVP if you know you are attending or if you think you may
   be attending.  This will help us arrange for a letter to security
   for all of Unigroup.  It will also help us to determine the correct
   amount of food and refreshments.

   To REGISTER for this event, please RSVP by:

   a) If at all possible, please use the Unigroup Registration Page:
      This will allow us to have some automation in the RSVP process.

   b) If you must Email us, send an EMail containing the FIRST and
      LAST NAMEs of the persons attending to the Unigroup RSVP
      The Email subject should start with "RSVP".
      You may optionally include your contact phone number (that
      day) or other current information.

      DO NOT simply reply to this Email, sending us back the entire
      announcement (we already have it); leaving the subject as it
      was, and NOT containing the phrase "RSVP" as requested.  In
      that case, your message just looks like failed mail and it
      makes it impossible to automate the RSVP process and get
      you registered for our event.

      ALSO: Do NOT give us an Email address which is over quota
      and cannot receive any new Email.  This causes us to receive
      bounces from your address when we send out the RSVP-ACKs.
      You must have a working and valid Email address in order
      to get on the Unigroup Meeting Attendee List which will
      grant you access to our meetings.  Be sure to proof-read
      your Email address before submitting the RSVP request.

  >>> AND: Do NOT give us an Email address which has anti-spam
      processing requiring our automated shell scripts to reply
      to your mail servers or visit a web page... that will NOT
      happen!  Be sure to add Unigroup to your "allow" lists!

   Please continue to check the Unigroup web site:
   for any last minute updates concerning this meeting.  Please
   check your Email for any last minute announcements prior to the
   meeting.  Note that only the Attendee First and Last Names will
   be provided to Chase Security.


   Outline of the Main IPv6 Presentation:

   Our speakers from Lucent Technologies plan to cover some or all of
   the following topics on IPv6:

   - Addressing architecture

     The size of an IPv6 address is now four times as large as an
     IPv4 address (128 bits compared to 32 bits).  This topic will
     cover the IPv6 addressing model, text representations of IPv6
     addresses, and definitions of IPv6 unicast, anycast, and
     multicast addresses as described in RFC 3513.

   - Header format

     The IP header has been modified to accommodate the larger
     address space, support new built-in features, and to streamline

   - Auto-configuration

     Auto-configuration allows for plug-and-play support of attached
     network nodes.  Models include stateless auto-configuration
     utilizing router advertisements, and stateful auto-configuration
     using a DHCPv6 server.  In some cases, both stateless and
     stateful auto-configuration may be supported on the same network.

   - Prefix delegation

     Prefix delegation describes a mechanism for delegating address
     prefixes to network sites.  The requirements for prefix delegation
     in IPv6 are defined in
     One conformant implementation of prefix delegation utilizes
     DHCPv6, and is defined in

     The 1CMP building is situated: South of Liberty Street, North
     of Pine Street, East of Broad/Nassau Street and West of William
     Street.  The building is one block east of Broadway, right
     behind 140 Broadway.

     The closest entrance to the conference center is from Nassau
     Street, first elevator bank from the Nassau Street entrance.

     The building is on a raised platform.  Walk up the outside
     stairs at Nassau Street and head for the guard's station at the
     south-west corner of the building.  Tell the guards you are
     heading for Unigroup.   Note: at times, you may need to enter
     the building on its lower level, on the east side of the block.

     They will inspect your ID and carry-ins and direct you to the
     meeting facility assuming you are on the Unigroup RSVP list.

     Once you get upstairs, enter the conference facility through
     its main doors.  There is a bank of large monitors to the left
     of the entrance which should direct you to the Unigroup meeting
     room (the room changes from month to month).  To the right of
     the main entrance is the concierge's desk, ask for help there
     if you need anything.  The conference facility has two levels,
     use the staircase to get to the upper level.  Most of the time,
     our meeting room has been upstairs, on the south side of the

     As always, also look out for Unigroup signs marking the path
     to the meeting room.  Also note, if you come early, we may not
     have our own signs in place yet (we have to commute there too).

     Transit By Train:  Take the J/M/Z to Broad Street and walk one
     block North to Pine St.  Take the 4/5 to Wall Street and walk
     North to Pine St., then East to Broad St.  Take the 2/3 to Wall
     Street, the North West exit is inside the Chase complex, else
     you will need to walk a block North and West.  See the MTA
     Downtown NYC Map (pdf) for detailed mass transit information:
