Campus computing resources

  • The answers to many of your computing questions are in the campus knowledge base.
  • Something not working? Check the current system status of campus services.
  • bConnected has links to many campus services, including email, calendar, file storage, and wireless access. Eduroam is the preferred wireless network, as it has the same connectivity as AirBears2 and has the potential to work at other institutions worldwide. Eduroam and AirBears2 require an access key. CalVisitor is convenient for guest access since no key or password is required; it has a more restricted level of service than Eduroam and AirBears2.
  • You can register your computer for wired (ethernet) network access. Look for 'Register devices for DHCP service' in the sidebar. DHCP registration is not required for wireless AirBears2/Eduroam access.
  • Manage your Calnet identity or sponsor a Calnet identity for non-Berkeley collaborators. (Do not use this service for providing access to AirBears.)
  • Access software products licensed to campus affiliates. Eligibility and cost varies by product. Many products have no direct user charge.
  • Use the campus VPN for access to e-journals and other digital library materials, as well as some high-security campus systems.


A variety of campus organizations are available to help with research computing and the broader topic of data science.


  • The bConnected Google apps, especially bDrive, are an excellent way to collaborate.
  • Bcourses (Canvas) can also be used to create projects and will be familiar to faculty and students from their courses.
  • Box has very good collaboration tools, but unfortunately it will likely be phased out by 2023 and is not the best choice for new projects.
  • A comparison of  tools is in the campus knowledge base.
  • For projects consisting of small amounts (recommended 1GB or less) of text or code and involving non-Berkeley collaborators or audience, GitHub is a useful service.
  • You can create a bConnected List (Google Group) for email communication and other collaboration features like shared bDrive content and calendars.

About CalNet passphrases and access keys

Your CalNet identity is used to authenticate and authorize your use of many campus web applications and services--notably, bMail's webmail interface. Normally you provide your CalNet identity and passphrase in a web portal when accessing these services. However, some applications and services cannot capture access through a web portal, and these require an access key instead of the usual CalNet passphrase. Such services include AirBears2/Eduroam and bMail when accessed through a mail client (Thunderbird, or the Mail client on a mobile device). Go to bConnected to manage your access key if you use one of these services.
