Dan Shechter Gelles

I'm a triple CCIE #13685 (RS, Security, SP). In the last 20 years I have worked with enterprise networking and mainframe system programming and I am the author of three CCIE workbooks published by leading vendors.

I am also the founder of
Marathon-Networks. If you have deployed Private VLANs, you MUST check it out: http://marathon-networks.com

I love teaching, and sharing information with others, and thats what this site is for. I also love spending time with my family and my hobbies are jogging and rowing.

I hope you will enjoy the technical
blog and my workbook.

Please send any feedback to me,
