UCSD Network Telescope Account and Usage Agreement

This document explains the policies for acceptable use of the UCSD Network Telescope facilities, account, and shared resources.

Please complete and submit the form below to request access to the UCSD Network Telescope facilities. Afterwards, the system administrator will be able to set up your account and follow up with you.

This form is for CAIDA employees and trusted collaborators only, who have been pre-approved for access to UCSD Network Telescope facilities. If you have not been instructed to fill out this form, your request will be denied.


  1. Facilities Policies
    1. You are expected to restrict your use of the UCSD Network Telescope facilities to lawful purposes consistent with and related to legitimate network and security research analysis of the collected data. Expressly prohibited are any uses in conflict with CAIDA projects. Ask the CAIDA PI if you have questions about the appropriate use of CAIDA machines or data.
    2. Use of these facilities to gain unauthorized access to any other account, at this facility or any other facility, is prohibited. Transmission of any material in violation of any U.S. or state regulation is prohibited. This includes, but is not limited to: copyrighted material (unless authorized by the copyright holder), threatening or obscene material, or material protected by trade secret
  2. Account Policies
    1. All accounts are assigned by an approved CAIDA staff member to, and for use by, a single individual. Sharing or loaning accounts is prohibited. Specifically, giving your password to anyone for any reason IS NOT appropriate, logging in and letting your guest use your account IS appropriate as long as you supervise your guest's use of your account.
    2. For authentication on CAIDA machines, you will submit a Secure Shell (SSH) public key to sysadmin at caida.org. You are expected to maintain quality passphrase(s) on CAIDA machines. A quality passphrase does not match any dictionary words, contains mixed case, numbers, punctuation and contains at least eight (8) characters. (CAIDA prohibits empty passphrase SSH keys on the UCSD Network Telescope machines.)
    3. For purposes of firewall configuration, you will submit an IP address, or IP address range, from which you will access CAIDA machines to sysadmin at caida.org.
  3. Shared Resources Policies
    1. CAIDA machines are part of a collaborative research environment, and so all user-created files are considered shared and have world-readable permission settings by default. This means that unless you take specific measures to restrict files you are authorized to control, you have no expectation that the information will remain private. You should set file permissions to be more restrictive on any files that contain information you want to keep private (e.g. your mail). You should limit the number of files of this nature stored on CAIDA machines in keeping with the spirit of open, collaborative research. Ask the CAIDA senior staff if you have questions about appropriate thresholds in this regard.
    2. CAIDA is responsible for restricting access to sensitive data such as raw trace data from the UCSD Network Telescope. By default, these files do not have world-readable permissions. Users must have specific group membership to gain read access to the telescope data files. Under no circumstances will you store this data in world-readable files or directories nor transfer the data to another host.
    3. Data collected from the UCSD Network Telescope fall under the purview of the University of California Electronics Communications Policy (UC ECP document).
    4. In consideration of other users on the shared compute resources, we expect users to:
      1. use the nice (1) command to lower the priority of large processes, or
      2. use the at (1) command to schedule jobs to run at night or over the weekend, and
      3. conserve resources like memory and disk space.

I understand and will abide by the above terms and conditions. If the propriety of any situation is unclear, I will ask for clarification from CAIDA PIs rather than making assumptions. I understand that my access to sensitive network data may be revoked if the terms and conditions are not adhered to.

Agree to terms and conditions * Please review the University of California's Electronic Communications Policy (UC ECP) covering acceptable conduct when using University resources. Enter your initials if you understand and will abide by the above terms and the conditions for use of the UCSD Network Telescope:
