Please create a cs591 personal web page on CS Unix machines with your personal photo, basic vita,  your interests in this class,  and including later on the potential semester projects that you may work on .  Note that in Unix system, your personal web site will be located in a subdirectory called public_html of your home directory. Create an cs591 directory under public_html. Then create a images directory under cs591. Put your photo image file there with filename <login>.jpg, where <login> is your ufp account name. Reference it as <img src="images/login.jpg"> in your cs591 web page. This will allow your classmates to find common interests and know each other. I will use a Perl script to copy your photo images and create a class photo album. See http://cs.uccs.edu/~cs301/graphics/scanning.htm for scanning your personal photo.  If you do not have recent photo, drop by my office. I can take it with my digital camera. You can also use my personal web page as a template. If you do not know how to setup your personal web page, drop by my office and I will help you get started.  This is part of your hw#1.

If you use Windows system at home, try to use free SSH Secure Shelll software package with SSH Secure Shell Client,/Secure File Transfer Client, from http://www.ssh.org/support/downloads/secureshellwks/non-commercial.html, to login to CS Unix machines. It is secure since the password is not transmitted as clear text and all data are encrytped.
You can also setup xterm over ssh http://www.linuks.mine.nu/windows/sshx.html

Through Microsoft MSDN Academic Alliance program, our EAS system admin will setup an account for you on http://msdn07.e-academy.com/elms/Storefront/Home.aspx?campus=ucoloradohae_cs to download the software packages such as Vista, WinXP, Win2003/2008 Server, Visual Studio 2005/2008, SQL2005, visio2003 for the exercises/projects of this class.

In EAS 143, we have PowerEdge 1900 2.66GHz Dual Quad Core Xeon Server called bilbo which run ESXi4 and 3 Dell Optiplex GX620 with Pentium D 3.2 GHz, 3.5GB memory, called walrus, wind, and walden wich run Windows XPand the vmware server 2.0.1 software package with customized ubuntu, Win2008 server, and previous iCTF vulnerability box image as virtual machines for CS591 exercises. Similarly in A210, we have one Dell Precision T3500 with WinXP 64 and 4 Dell Optiplex 960 PCs with Vista for CS591 exercises. You can download and install the vmware server client GUI software in you own PC to configure and run the virtual machines on these servers.

Disability Service:

If you have a disability for which you are requesting an accommodation, you are encouraged to contact the Disability Services Office within the first week of classes. The Disability Services Office is located in Main Hall #105. (Phone # is 262-3354.)
