Mark Eichin

I work in the Cygnus Support East Coast Office, in Cambridge, MA. Our phone number is +1 617 354 2750 and our fax number is +1 617 354 7161. Our office was Somerville MA, 42.4N 71.1W

here, but I haven't had time to locate the new one on a map yet. It's about 2.5 miles from here.

SGML

I'm currently studying SGML and have written a few articles relating to it.

Bio (for WICS)

Mark Eichin has been involved in the development of the Kerberos network security system since his days as an undergraduate at MIT. He was also involved in the design and implementation of the Zephyr Notification Service, which has been billed as one of the most complex uses of Kerberos ever seen in an application. Currently, Mr. Eichin is the primary development engineer for Cygnus Network Security, and continues to work closely with MIT on the development of Kerberos.

If you want to find out about me, for now you'll have to check my MIT home page.

Eventually this entry will be updated with Cygnus-specific information. For now, look at the Cygnus Web Server for more information about Cygnus.

In particular, I work on

Cygnus Network Security, which means that I work on
- Kerberos V4
- Kerberos V5
- Other network-level programming
Customer Support for the Cygnus Development Environment.
Local (East Coast office) system and network administration. (If you want that job, send email to resumes@cygnus.com.)

If you're looking for Random number generator code in tcl, it's here. The grapheditor is here and the dialog box code is here.

If you're looking for an impressive grapheditor (designed specifically for editing state machine diagrams) look at Stephen Edwards home page where he has the source code to "states" and the "sc-1.0" StateChart editor. Both are far more sophisticated than my demo example here.

I've put together some Debian Linux packages for my own use which you are welcome to download at your own risk. These are not products of Cygnus Support; they are just things that made my work a little easier.

Several years ago I wrote a driver for the HandyKey Twiddler one-hand keyboard-mouse. Upon learning that other people actually use this device, namely the MIT Media Lab Wearable Computing Project, I finally polished up the code for public release. Here is a gzipped tar file of the sources.
