Establish a VPN connection

To establish a connection:

  • Traffic to servers of the University of Vienna:
    f5fpc -s -t vpn.univie.ac.at -u u:account-UserID -d /etc/ssl/certs/

In the parameter -u type in your u:account UserID. Typing in the directory the certificates are in is not always necessary and can be ignored (Option: -d /etc/ssl/certs/).

Type in your u:account password and click Enter.
The connection should be up and running.

Manually install root certificate

If you receive the failure notice Server certificate verfication failed, do the following steps:

  1. Download the Root-Zertifikat.

    sudo     mv SHA-2_Root_USERTrust_RSA_Certification_Authority.crt /etc/ssl/certs/USERTrust_RSA_Certification_Authority.pem

    sudo     ln -s /etc/ssl/certs/USERTrust_RSA_Certification_Authority.pem /etc/ssl/certs/fc5a8f99.0
