Server Registration

Campus computing supporters can register multiple computers located on their network(s) by sending the following information for each system/server using the “tab separated value” format to the OIT security team (security @ uci.edu):

  • Requester UCInetID
  • Responsible UCInetID (optional)
  • Hostname
  • Ports open TCP (comma separated list)
  • Ports open UDP (comma separated list)
  • Comments (optional)

Yes. Choose the “I would like to specify which ports to open.” option. After being prompted for your computer name and contact information, you will be able to select from a list of pre-defined ports. The “I need to define additional ports” option is also available to you at this point if you need to open ports that are not pre-defined.

Note: If you need to have more than 5 open ports, we suggest that you choose the option “This system is a server. I run my own firewall or have taken other security precautions.” and run your own local firewall and/or other security mechanisms.
