NIFTY SAMBA TECHNIQUES AND HACKERY

By Adam Williams

The link to Adam’s presentation slides:

ftp://www.kalamazoolinux.org/pub/pdf/SambaHackery.pdf

Samba is a software package that gives network administrators
flexibility and freedom in terms of setup, configuration, and
choice of systems and equipment. Because of all that it offers,
Samba has grown in popularity, and continues to do so, every
year since its release in 1992. Multiple platform open source
networking software.

This was not a beginner’s presentation about Samba. If you
are responsible for the configuration and support of a business’
computer network (and are running Samba networking) this
was the information that you have been missing and needing.
Adam revealed some cool tweaks that make support tolerable.
Multiple platforms, security issues, and the ever pesky "loose
nut behind the keyboard" are handled with keen forethought.

Access Control Lists (ACL) are used to give a user access
rights to a given object when using the network. Find out
more about what ACL is and how it works here:

Microsoft NT ACL support and configuration with Open Source
Samba networking software. Here is a list of the tweaks that
were explained. You can see more detail in the slides. These
settings made network functionality a whole lot better. These
were additions to the default configuration settings found in

the file: samba.conf

map acl inherit = yes
store dos attributes = yes
hide dot files = yes
veto files = /*.exe /*.EXE /*.pif /*.PIF /*.com /*.COM
delete veto files = yes
delete readonly = yes

Adam explained the configuration of the network trash cans and
why this method worked so well, eliminating the frustration of lost
data and support calls. He showed us how print services could
produce .pdf files that are e-mailed to the user directly instead

of being printed on network printers. Adam revealed how the virus
and many security issues are addressed at the network admin level.
Management of the user shares and desktop configuration was also
addressed.

THE ONION ROUTER PROJECT & ROGER DINGLEDINE

The *FOUR* Best Things From Redmond (Postponed!)
Presented by Robert Brown at a later date…

There were a couple of humorous posts to the KLUG Members
mailing list that suggested that perhaps the postponement was
because of the failure to come up with four good things from

Microsoft. ODBC was certainly one good thing to come out of
Redmond’s campus. Can you come up with three more good things?
If you say IE6, Office XP, and Outlook Express… you are
profoundly mistaken.

THE ONION ROUTER PROJECT
MPEG Video Presentation by Roger Dingledine

A cryptographer and network security expert, Roger Dingledine spoke
about the Onion Router (TOR) project.
http://freehaven.net/people.html

The Electronic Frontier Foundation (EFF) is a nonprofit group working
to protect your digital rights. Roger went to MIT and worked for the NSA
at one time.
http://tor.eff.org/
http://tor.eff.org/overview.html

Tor's technology aims to provide Internet users with protection against
"traffic analysis," a form of network surveillance that threatens personal
anonymity and privacy, confidential business activities and relationships,
and state security.

Roger said he tells his grandparent that he works with communicating
privately, he tells his computer community peers that he works with
anonymity networks, and the military people hear that he works
with traffic analysis resistant communication networks.

The question was posed, "Who needs anonymity?" Different models were
discussed including remailers, mixing servers, and proxy servers. Multiple
TOR servers replicating encrypted data to hide source and target. Location
Hidden Servers were discussed for their strategic benefits.

TOR was a response to a need. Running since October 2003, there are 150
TOR server nodes worldwide with 15,000 users generating over 50,000
hits a day. The bandwidth traffic is 5 to 10 Mbs. Three deep encrypted
mixing of traffic. Looks just like a SOCKS proxy to the client. Supports

BSD, Mac OS X, Solaris, Windows, and Linux platforms.

Onion routing application Tor makes PCWorld's top 100

Larger social political issues are represented by this project. Privacy

and security are needed and in fact are the preferred state of internet
user communications. Anonymity is the cornerstone of your right to
privacy. Free speech is the ideal and secure private speech is the
insurance that this exists.

A big round of applause for Mark Jones who stepped up and put this
presentation together on 24 hours notice. There was as much fun getting
the MPEG display technology configured as the watching of the the Norway
Linux Users Group (NLUG) movie. Lots of humor and open source perspective
in both. THANKS MARK!!!

OPEN SOURCE @ EAST GRAND RAPIDS PUBLIC SCHOOLS

Presented by Jeff Crawford

Jeff Crawford is the Manager of Networking and Security with East
Grand Rapids Public Schools. He used an IBM ThinkPad T42 running
SuSE v9.3 as the OS and the OpenOffice.org Impress application to
display his presentation slides. The ThinkPad worked great with the
KLUG InFocus SVGA video projector.

Jeff broke his presentation down into three parts. The general theme
was Open Source operating system and application use at East Grand
Rapids Public Schools. East GR PS has 1,500 workstations running
Mac OSX, Windows, and Linux. Users can log into the network at
home, from the school, or from a web connected browser any where
in the world. The network could have 2,000 users logged in or more.
Many of those users are using open source software applications.

Jeff mentioned that one of the convinced supporters of Open Source
Software is his boss! Having a savvy person in the top IT spot makes
the environment progressive and obviously very cost effective. After
all, school funding comes from each of us and OSS total cost of
implementation is lower and the software is better, generally speaking.
Spend the money on IT staff salaries and not proprietary software.

Open Source Programs that EGRPS has had success with:

Moodle – Course Management System (vs. Blackboard)
http://www.moodle.org


Mantis Bug Tracking System
http://www.mantisbt.org

b2evolution (vs. Blogger)
http://www.b2evolution.net

phpCollab (vs. Track-It)
http://www.php-collab.org

One or Zero Helpdesk (vs. Track-It)
http://www.oneorzero.com/

We heard about each of these Open Source Software applications and the
alternatives. The major areas of concern were listed as perception,
support personnel, and staff training. The perceptions of non-IT managers
are slowly changing. More support personnel are needed and higher pay
is needed to secure OSS savvy technical managers. Staff and users both
need lots of training, they just never get enough.

Next Jeff presented "Leveraging Novell Open Enterprise Server in Your
Organization." The differences between SuSE SLES 9 and NetWare 6.5
SP3 (OES). SLES is focused on application serving. The Novell Storage
Services (NSS) File System is the default file system for NetWare 6 and
later. Jeff said that this is the most significant aspect of OES for an
organization.

From the Novell web site:
Novell's OES 1.0 is most notable for the range of options it offers
companies, particularly those now running NetWare. OES can be backed
by the SuSE Linux or NetWare platforms and provides a solid route for
enterprises looking to mix these platforms or migrate between them.
What's more, OES provides for synchronization with or migration from
Windows NT, Windows 2000 and Windows Server 2003. For more,
go to www.novell.com/oes.

By the way, Jeff is quoted on the Novell Open Enterprise Server web site.
He said he has received nothing for his exuberant public support of Novell.
They could always just surprise him with a new red Ferrari with a "GR8NOES"
custom license plate… Maybe a T-shirt and a coffee mug would be nice too!

In the final part of Jeff’s presentation, he discussed Mac OS X with OES.
He showed some configuration information and told us about some quirks.
FreeRADIUS and eDirectory issues and tips were also shared.

There was a brisk period of Q & A after the summation. Questions were
fielded throughout the presentation. Jeff found several people present
with education software experience who asked questions that yielded
an even better understanding of the software features and considerations.

KLUG MONTHLY GENERAL ASSISTANCE MEETING

Hosted by KLUG Chairperson John Bridleman

There was an abbreviated introduction tonight after the
server room equipment checks were completed. The OSS
wireless network authentication program "NoCatAuth" was
not responding. The Devil Linux firewall box seemed to
be stalled. Everything was back to normal within minutes
and was perhaps due to weather related power issues.

There was a discussion about the 2005 KLUG 4th of July
gathering at Shirley and Bruce’s Mandigo quinta. There
were no reports of anything but fun and fine food. Thanks
to the Smiths for opening up their lovely home and grounds
to the members of KLUG and their significant others for
this annual event. Whitney, the large Newfoundland, was
the canine hostess for the four-legged guests. WOOF!

Tonight Kevin brought in his PC to get some help with a
Apache web server configuration in Debian. First he and
Dirk tackled a pesky X problem that was methodically
resolved. KLUG Installmaster Andrew Thompson was on top

of the situation tonight and reported no requests for
help with the installation of any of the many Linux
distributions that can be supported by KLUG. Is it so

easy now that anyone can install Linux themselves?

Within the discussions of the evening one could hear
world politics, economics, some silicon history, and the
probable future of computer technology applications.

Jon Smitley's beautiful 18 month old daughter, is KLUG's
youngest official voting member. See her picture below.
She was a delight all evening and entertained as she was
being entertained. Knowing her name might be valuable
when playing Final Geek Jeopardy this Fall.

At least half a dozen laptops were connected to the
Jas Networks 2.3 mbps DSL WAP and quietly doing
one task or another. The snacks were popular tonight.

This meeting is intended for those who are just curious
about Linux and Open Source software, who need some
help getting started, or want some extra eyes to look at
your advanced problem. You can also bring your computer
in order to have Linux installed on it, at no charge; or

to try a Linux distribution that boots from CD and requires
no change to your system's current software.

If you would like assistance with a specific problem please
e-mail a description to installmaster@kalamazoolinux.org,
so we can be sure someone familiar with your issue will be
available to assist you.

If you would like to install Linux on a system, or you
need help with Linux, please fill out a Help Request so
that someone can research your hardware/software, etc...
http://kalamazoolinux.org/meetings/installmeeting.php

Installations and assistance are done by appointment
ONLY. You must fill out the appropriate form one week
prior to the meeting. If you only have general questions

or curiosity you don't need to do anything but show up!
