Greetings programs,

The University of Waterloo is currently in the process of putting a perimeter firewall in place around the campus, which will block incoming traffic on all but selectively-enabled ports. It will be enabled for the MC, including all CSC machines, sometime this week.

We will be working with UW IST to ensure that exceptions are added to the firewall for the services normally operated by the CSC; however, if you run a server on a different port, or otherwise depend on incoming connections, this will no longer work. Connections from inside UW will continue to work normally.

If you have a specific service for which you would like CSC systems committee to consider an exception to the firewall, please contact syscom@csclub.uwaterloo.ca and explain: - Which server(s) your service needs to be given exceptions on - Which port(s) you need opened - The purpose of the service

Syscom will take each request under consideration, but please be aware that since we have not yet decided on a policy for exceptions, we cannot offer any guarantees that your request will be granted.

Thanks for your patience,

Sean Hunt CSC Sysadmin
