Cndnsd Vrsn: 4 PM WEDNESDAY 1/15 ACS Room 123- Open Source Wireless Tools
The next meeting of the Front Range UNIX Users
Group (FRUUG) will be held at 4:00 P.M. on Wednesday, January 15.
Dirk Grunwald from the University of Colorado will be discussing
his research group's work using open source tools for wireless
community networks.
The proliferation of inexpensive 802.11b hardware
makes it possible to construct wireless networks. More importantly,
the growth in open source software enables controlling the
internal function of 802.11b access points. Dirk Grunwald and his
research group are working to build a "community wireless network"
using relatively
conventional hardware and open source access point software.
The talk will outline the motivation for the CommuNet project
and much of the technology they have developed or have in use for
the project. At the core of the software is the "Click Modular Router",
developed at MIT; this has been extended to implement several ad hoc routing
protocols, and Dirk will illustrate why it's such a useful environment.
He'll also how how they integrated Click into a standard network simulation
environment (ns2), allowing them to move identical code between a simulated
environment and deployed hardware. Lastly, Dirk will discuss
plans to use the HostAP and LocustWorld open source projects to
build a scalable "mesh network", hopefully suitable for building
community networks.
Dirk Grunwald is an associate professor in the computer science
department, and works on a number of areas in computer systems
including computer architecture, networking and storage systems.
He received his PhD from the University of Illinois in 1989
and is profusely glad to be living in Colorado.
This meeting will be in room 123 of the CU Academic Computing
Center building at Arapahoe and Marine Streets in Boulder. Marine St intersects
Arapahoe at 38th St; the Computing Center is on the southwest corner.
At our December 2002 meeting, Cricket Liu of Men & Mice
talked about a variety of threats to the Internet's
DNS infrastructure, including distributed
denial-of-service attacks, bugs in various BIND versions,
the astonishing "normal" 98 percent rate
of bogus queries seen at the root name servers.
Cricket's slides are available in the FRUUG meeting archive at
www.fruug.org/mtgarchive/index.html.
Our next meeting is tentatively scheduled for February
3, 2003, with a talk on IP-based Storage Area Networks,
otherwise known as iSCSI.
Are you familiar with the new FRUUG Library
Merit Badge program? If not, it might be a good time
to learn all about it by consulting the
FRUUG Library
page on our Web site.
FRUUG merit badge holders are eligible for our frequent
book give-aways, and all you have to do for a lifetime
membership is to review any book from the FRUUG library
and send the review to gaede at fruug.org.
Addison-Wesley
sent us two copies
each of "Wireless Security and Privacy," "Internet Site
Security," and "Honeypots-- Tracking Hackers."
These books are available to FRUUG Library Merit Badge
holders who sign up on our Web site before noon the day
of the meeting. Are you dying to get your
hands one one of these hot titles? If you're not yet
a Merit Badge holder, review any book
from the FRUUG library before noon the day of the meeting, and
you can take your pick of the three books.
Finally, we once again have a
Gift Certificate to SoftPro Books
to give away to a FRUUG member
at the meeting.
The list of new books this month includes:
- Test-Driven Development By Example,
from Addison-Wesley
- Proceedings of the 2nd Workshop on Industrial Experiences with
Systems Software (WIESS '02),
from the USENIX Association
- Proceedings of CARDIS '02, Fifth Smart Card Resarch and
Advanced Application Conference,
from the USENIX Association
- Proceedings of the 5th Symposium on Operating Systems Design
and Implementation (OSDI '02),
from the USENIX Association
- Proceedings of LISA XVI, the Sixteenth Systems Administration Conference,
from the USENIX Association
You may check out books using your business card as your
library card; you must be on the membership list to check books out. Books
are due at the meeting following the one in which they are checked out.
Remember that your FRUUG membership entitles you to discounts
on your book orders from both New Riders Publishing and O'Reilly &
Associates; refer to the FRUUG Web site for details.
The New Riders discount program has changed; pick up a
discount coupon with our secret password at the meeting.
