Ubuntu 16.04 64bit – OpenVPN and SafeNet iKey 5100 token

My company allows remote connection to some computers by OpenVPN, but you have to use SafeNet iKey 5100 token. There is small tutorial how can you install and configure OpenVPN with iKey 5100 token and how to modify windows *.ovpn files to be a Linux compatible.


Important note: OpenVPN contains bug and it doesn’t work with systemd and pkcs11 token. This is our case, Ubuntu 16.04 use systemd and SafeNet has pkcs11 API. This bug should be fixed in OpenVPN 2.5. You can find more informatinon at: https://community.openvpn.net/openvpn/ticket/538


Required software installation

  1. Open terminal and run command
    sudo apt-get install openvpn opensc
  2. Install SAC 9 version
    sudo dpkg -i SafenetAuthenticationClient-9.0.43-0_amd64.deb

SafeNet iKey 5100 validation

  1. Open SafeNet authentication client
  2. Check your token info
  3. If you cannot see token info, restart your computer

Gets SafeNet iKey 5100 certificate ID

  1. Open terminal and run command
    openvpn --show-pkcs11-ids /usr/lib/libeTPkcs11.so
  2. You should see similar output
     DN: C=XX, L=City, O=Company, OU=DEV, CN=John Dove GVPN
     Serial: 431B6D0E0003000003AB
     Serialized id: SafeNet\x2C\x20Inc\x2E/eToken/0223253a/John\x20Dove\x205100/9C92935DE546178D
  3. We will use “Serialized id” attribute in our VPN.ovpn file


OpenVPN configuration

  1. I received from my company these files for OpenVPN:
    • VPN.ovpn – configuration file for Windows OpenVPN
    • gvpn_ca.cer – CA certificate
    • ta.key – key file

    You should have similar files too

  2. Copy these files to “/etc/openvpn” folder
  3. Open /etc/openvpn/VPN.ovpn in editor e.g. by command
     sudo nano /etc/openvpn/VPN.ovpn
  4. My original VPN.ovpn file looked like this
    dev tun
    proto udp
    remote 1111
    resolv-retry infinite
    tls-remote ovpn.server.com
    ca "C:\\Program Files\\OpenVPN\\config\\gvpn_ca.cer"
    cryptoapicert "SUBJ:John Dove GVPN"
    tls-auth ta.key 1
    verb 4
  5. You should modify file to this (I modified only bold lines)
    dev tun
    proto udp
    remote 1111
    resolv-retry infinite
    tls-remote ovpn.server.com
    pkcs11-providers /usr/lib/libeTPkcs11.so
    pkcs11-id 'SafeNet\x2C\x20Inc\x2E/eToken/0223253a/John\x20Dove\x205100/9C92935DE546178D'
    tls-auth /etc/openvpn/ta.key 1
    verb 4
    "pkcs11-id" is  "Serialized id" attribute from command "openvpn --show-pkcs11-ids /usr/lib/libeTPkcs11.so"

Connection to OpenVPN network

  1. In terminal run command
     sudo openvpn --config /etc/openvpn/VPN.ovpn --ca /etc/openvpn/gvpn_ca.cer
  2. When you will see similar lines
    Wed Apr 23 09:39:40 2014 us=105713 VERIFY X509NAME OK: /C=XX/L=City/O=Company/OU=central/CN=vpn.server.xx

    Enter John Dove token Password:

    write PIN password and hit ENTER

  3. When you will see lines
    Wed Apr 23 09:40:23 2014 us=121821 /sbin/ip route add via
    Wed Apr 23 09:40:30 2014 us=511121 /sbin/ip route add via
