Connecting to VMware vCenter & Auxiliary Services

DoIT's VMware vSphere instances require certain clients and/or specific URLs for access. You may also import the Virtualization Team's root certificate authority certificate to prevent SSL errors.

DoIT's VMware vSphere instances can be connected to via the VMware Web Clients:

  • for CCI Virtualization (99.9% of all VMs are here)
    • The HTML5 client is the preferred client for system administrators and avoids issues with Adobe Flash
There are firewalls protecting these services from external access. If you are on campus, but not using ResNet, and cannot connect please contact for assistance. If you are off-campus please use static WiscVPN to connect. These services are IPv4 only right now.

Depending on your browser you may see SSL certificate warnings for the infrastructure. VMware vSphere creates its own SSL root CA and uses that for the cryptographic operations inside the infrastructure. You can import the SSL certificates by:
  1. Downloading them from
  2. Extract the contents of the ZIP file. The result is a folder that contains two types of files. Files with a number as the extension (.0, .1, and so on) are root certificates. Files with an extension that starts with an r (.r0,. r1, and so on) are CRL files associated with a certificate.
  3. Install the certificate files as trusted certificates by following the process that is appropriate for your operating system. For most Microsoft Windows systems, you can follow the instructions at
Firefox has its own trusted roots store and does not use the operating system store. If you are working with Firefox, download the certificate as described above, and then select Tools > Options, click Advanced, and click Certificates to import the certificate into Firefox.
