You can just simply run  'pki --version' to see the version output.

Ricardo,

You can check what version of Dogtag you are running by the RPM Name-Version-Release (NVR) via the command-line:
  • rpm -qa pki-server
    pki-server-10.2.2-0.1.fc21.noarch

In the above example, a Fedora 21 machine contains Dogtag 10.2.2.

For the latest Dogtag versions on various platforms, see the following:

Thanks,
