Re-Register for Spring!

It’s that time again! To maintain your ResNet connections, please register your computer(s) by visiting the ResNet website (, and clicking on the Register Connection icon on the top menu.

Those who have registered between Sunday, March 20th, 2011 and Monday, April 4th, 2011, will experience no loss of connection to the Internet. We will be clearing out the old registration logs on Tuesday, April 5th, 2011, at noon.

If you have not registered since March 20th, 2011, please re-register before noon, Tuesday, April 5th, 2011 to avoid an interruption to your connection to the Internet.

If you forget to register by noon on Tuesday, April 5th, 2011, just go to the ResNet website and register to get your connection back.

You need to register from your on-campus residence. You will need to register both your wired AND wireless connections separately. Make sure you are connected to a ResNet access point, and not a “UCSD” access point when you are registering your wireless connection. The registration process will include a security scan of your computer to verify that it is protected from the most common Internet viruses.

** Any devices that we helped you register (game systems, routers, et) after July 1st of 2010, or that have been active in the last 60 days do NOT need to be re-registered. **

For any questions or concerns, please contact ResNet. Have a great Spring Quarter!


Reconfiguration on Blocked Ports

To provide a more open network inline with the university setting, while still providing some network security, ResNet has re-configured the incoming port blocks. Below is a list of ports that are blocked:

  • 0-21
  • 23-1024
  • 1025-1027
  • 2869
  • 3306
  • 3689
  • 5000
  • 5357
  • 6000-6010

Any port not listed above remains unblocked.

This will allow students who live on campus to do things such as host games on their gaming consoles or their computers. Also, ssh and remote desktop connections will also be possible.

Thank you for your patience as we try to balance network usability and security. Please contact us if you have any questions regarding this information.

URGENT: Storm Worm Bot/Virus

There is a particularly nasty bot/virus spreading rapidly through the Internet called (among other things) Storm Worm. Thousands of computers have already been identified through Tritonlink as infected. This bot/virus is getting spread through links in a variety of emails. You might recognize the email as an “e-greeting card” (from someone you don’t know), an invitation to see video or login information for a service you’ve never signed up for. If you clicked on the link provided in any of those emails, your computer may be infected.

In most cases, the only noticeable symptom of this bot/virus is your machine running slower. Updated antivirus software is detecting and removing some variations of Storm Worm. The latest Microsoft Update has also helped identify and remove some versions of Storm Worm. If you think you may be infected, go to, adn log in to one of the tools on the left-hand menu. If you get re-directed to the “Storm Worm Alert” page, there is a good chance your computer is infected. Visit the Storm Worm site for more information and to make sure your computer is secure before connecting to the UC San Diego network.

Please be advised that if you bring an infected machine to campus, your connection will be blocked until your computer is cleaned. ResNet will have technicians in the common area of your college during Move In Weekend and Welcome Week. Keep in mind that this is a very busy time, though, and you may need to wait, especially if there are a lot of infected computers.
