Step 1. Request access (if you need to)

OpenVPN works on a per-user permission basis. As such, you normally have to request access to resources like your desktop PC or other protected resources not normally accessible from off campus.

However, there are some exceptions listed below which are automatically available to relevant staff that you don’t need to explicitly request and will just work for you. If in doubt about your OpenVPN permissions, please check your OpenVPN Account Details.

For off campus access to Agresso and iTrent

Staff who can access Agresso are automatically given access to: https://agrlive.essex.ac.uk/agresso/Login/Login.aspx

Staff who have access to iTrent (People Manager etc) are automatically given access to: https://ihr.essex.ac.uk/tlive_web/wrd/run/etadm001gf.open

For Remote Desktop Connection and access to other resources and services

If you require more than the default access to Agresso and/or iTrent, then you must email the IT Helpdesk at it.helpdesk@essex.ac.uk with the following details:

  • your Essex ID
  • your office computer's S number (if you want to use Remote Desktop Connection)
  • details of other resources or services you want to use that can't be accessed via Remote Desktop Connection

Please allow one working day for us to activate OpenVPN on your account - we'll send you a confirmation email once it's done. Once you have been given access continue to the next steps.
