VPN

Access HLRS compute service using VPN

Access to HLRS compute platforms requires a registration of the clients IP address in the firewall. If the IP address is not static a connection via VPN is recommended.

To use this feature, please contact your project supervisor and ask him to add the vpn-hww resource in the HLRS user database. Install the Fortigate software on your laptop. The Software can be downloaded at

 https://www.forticlient.com (Windows, Mac)
 https://github.com/adrienverge/openfortivpn (Linux and Mac)

On Fedora, OpenSUSE, and latest Ubuntu openfortivpn is available via packet manager.

On Mac OSX openfortivpn can also be installed via Homebrew or Macports.

Using the VPN on Windows

Type your login and password to connect. If this works, you are able to login on the frontend servers using ssh e.g.

  ssh -l <your_login> hawk.hww.hlrs.de

Configuration of openfortivpn on Linux

Please insert the following data into your config file (probably /etc/openfortivpn/config):

host = rmgw.hww.hlrs.de
port = 443
username = <your username>
# trusted-cert = 5338851771baa67d1a29fa8df7d49ddbd83cbbd517c78e032bf5ab305eaba3f8
# ca-file = /usr/share/ca-certificates/mozilla/Deutsche_Telekom_Root_CA_2.crt

Remarks:

• A user certificate is not required.
• The trusted-cert (cf. next to last line in config file template given above) is the digest of the server's certificate which is subject to change every couple of years. It might hence be wise not to specify this in your config file.
• The VPN gateway uses a DFN certificate which is issued below the root CA tree of the German Telekom, one of the CA's trusted by most browsers.
• If your Openssl library is configured correctly and your certificate bundles are installed properly (e.g. via the package manager of your operating system) it should not be necessary to explicitly specify the CA certificate (cf. last line of the config file template given above). Otherwise, download the required certificate here, uncomment the last line and specify the location of the downloaded file there.
