The feature presentation for the ALE Central Meeting
on Thursday, May 19th, at 7:30pm will be:

“An Intro to Sudo”
presented by Michael Potter of
Replatform Technologies, LLC

– The sudo command is a security tool that comes pre-installed
on many *NIX systems, including Mac OS X, and most distributions
of Linux. sudo allows for fine grained control of privileges as an
alternative to setuid programs & scripts, turning on read & write
privileges on sensitive files, sharing passwords, and (gasp) giving
out the root password.
– This presentation will begin with a quick demo for those of you who
are unfamiliar with sudo. The complete syntax of the configuration
file will be explained starting with the simplest rules to the most
complex. Finishing with a discussion recipes to solve real world
– I started developing this presentation after getting frustrated
trying to understand the sudo configuration file syntax. I added
the real world problem while helping people on the sudo mailing

– Michael has been working in IT since 1989 when he switched
from programming automotive embedded systems. Since that
time he has been involved in projects related to moving mainframe
applications to UNIX and Linux using open-source technologies.
Michael is the lead author of the open source library that allows
socket code originally developed on the mainframe to be recompiled
on Linux: http://code.google.com/p/ezasoket/
– Recently Michael is work on various projects from Groovy/Grails to
development of iPhone/Blackberry/Android applications for business.
– In 2009 Michael and his wife Lanna moved their consulting business
from Chicago to Atlanta.

[ED comment]:
Michael is an excellent presenter who last spoke at ALE in May
of 2010 with a first rate presentation on security and debugging
tips for bash shell scripting. We have no doubt that the sudo talk
will be similarly polished and informative and encourage
everyone who can do so to attend. Per presenter preference,
this talk will not be recorded, though slides are available on
Michael Potter’s download page.

We will be meeting at our usual venue: Emory Law School,
Gambrel Hall, rm 1C. Meeting time frame is 7:30pm to ~9:30pm
