Workstations Update, Tues 9/17
I have done a non-critical update to our automated filesystem mounting for home directories. These will time-out after 90 minutes (beyond the typical class/lab sessions) to clear up resources on systems. While the connections are still active and in use, there will be no issues.

2012 Workstation Upgrades
[LightDM screenshot ]Welcome back. Plenty of changes have occurred to network this summer, here is a summary.
The new workstations in the Asprey and Intro labs have quad-core Intel i7 2600 CPUs running at 3.4 GHz with 8 GB of RAM. The new workstations in the 105 classroom have dual-core Intel Atom D2700 chips runnings at 2.13text/html2012-11-12T16:27:06+00:00Anonymous (anonymous@undisclosed.example.com)2012-11-12_mote_migration

2012-11-12 Mote Migration
The new remote access server is finally ready for general usage. This means everyone will have remote access to a system that has all the same software and settings as a department workstation. Fire up Racket and do your CMPU 101 homework, submit your CMPU 203 homework assignment, or just open up IDLE to work on your NLTK work, whatever you need.text/html2015-08-26T21:04:09+00:00Anonymous (anonymous@undisclosed.example.com)windows

Using VNC on Windows
Setup
Setting up the programs to connect to a VNC server is not too difficult. You will, however, need to download two programs: a SSH client and a VNC client. The SSH client will make a secure connection between your computer and the VNC server and the VNC client will use this connection to draw a display on your screen.text/html2020-01-30T19:31:41+00:00Anonymous (anonymous@undisclosed.example.com)tips_for_instructors

Where are my Icons?
If you find that you have logged onto the system this year, and all of your shortcut icons are missing, don't worry. You can get them back.
First off, the buttons are still there. The icon has just been set to “no icon.” If you hover over the taskbar, you will see the application the blank button links to, as shown.text/html2015-08-27T14:13:27+00:00Anonymous (anonymous@undisclosed.example.com)2013_winter_updates

2013 Winter Updates
Welcome back. There has been some good quiet time in January which works well for pushing out updates. All of the workstations remain on Ubuntu 12.04.1, but several components have been updated.

SSL Site Certification
We run two apache2 servers at this site.
These two instances of apache2 serve multiple wikis and web sites.
They are located in the Computer Science Department of Vassar College.
As a result, they all get the same site certificate. In some cases that works just fine. But in some cases your browser will complain about not being sure if it should trust the certificate or not being able to verify the certificate.text/html2010-08-31T20:47:29+00:00Anonymous (anonymous@undisclosed.example.com)recently_installed_software

Searching the CS websites
We actually have several publicly viewable websites here at CS. There is the primary site and in addition several projects have their own servers. To further muddle things, we have a content management system, conventional web pages and cgi pages.text/html2015-08-26T21:04:09+00:00Anonymous (anonymous@undisclosed.example.com)osx

Using VNC on Mac OS X
Setup
Download and install a secure shell client
As you may have heard, the Mac OS X operating system is built off of a version of Unix, FreeBSD. You'll be happy to hear that this means you already have a secure shell client installed, the Unix native ssh. You will find it from the Terminal - more on that later.text/html2010-05-04T13:36:34+00:00Anonymous (anonymous@undisclosed.example.com)speed_tips

Why is my session so slow?
VNC is sending the image of your screen over the network between the server (here at CS) and your client (the machine where you are working). Depending on the network speed, the load on the server, the speed of your machine and the protocols vnc is trying to follow, the speed of …
