The Columbia, Maryland Linux Users Group (CALUG) will meet on Wednesday, 
October 12th at 7:00 PM at our /training/etc location at 7150 Riverwood 
Drive, Suite J, Columbia, Md 21046.

The topic of the meeting will be: "Using tb-sshdfilter to Thwart 
Automated ssh Attacks" presented by Eric Smith and Robert Burgoyne of 
True Blade Systems, Inc.

Brute force ssh break-in attempts using automated programs in an attempt 
to secure shell access to a Linux system are commonplace. If you study 
the logfiles of nearly any Linux system exposed to the Internet you will 
often see hundreds or even thousands of break-in attempts each week.

An existing program, sshdfilter, attempts to solve this problem. Eric 
Smith studied sshdfilter and determined that a new solution was required 
to address his clients' requirements. tb-sshdfilter is a new program, 
written in Python, which attempts to provide a more flexible and robust 

tb-sshdfilter will be released to the general public at the same time as 
the CALUG meeting under the GPL license.

Refreshments will be served.
