Virtual Private Network (VPN) to Fermilab¶
The information below needs to be updated as now Fermilab has moved to a VPN system that requires a token, either soft or hard.Currently one way to get get started is:
- First you need to get a token by opening a ticket RSA Token Request form (takes a while and both hard and soft tokens are limited)
- Set it up
- Use it
Don't know how to get a vpn with the cisco alternatives. If you manage to work out how to set a vpn with one of the alternatives below please update this wiki page.

- Virtual Private Network (VPN) to Fermilab
Some resources can be accessed only from within Fermilab network. For some, the access outside Fermilab network is still allowed but crippled.
To allow users to access these resources in full by connecting via a Virtual Private Network (VPN), which needs to be set up on the client node.
A quite understandable description of the system is documented in CD DocDB 3435 .
As stated in there, Fermilab has chosen Cisco "AnyConnect", which provides a client to connect to its VPN.
Cisco provides also a client to "enter" the VPN. There is also a free alternative.
Cisco client installation¶
The official Cisco AnyConnect client is supported for Linux, OSX and Windows.
That software is only available via Fermilab: visit https://vpn.fnal.gov and log in with your Services account credential (just the user name, without
@services.fnal.gov). The web site will guide you to install the software.
Once installed, you can start the client interface and fill in the information in the table below.
Additional setup for Linux¶
The web site will just download a "script"
vpnsetup.sh. That is not just the script (it contains the binary data of the package itself).
To install that, run
sudo sh vpnsetup.shor similar. In short: you need administrator privileges.
The script will also install SysV scripts to start and stop the VPN. It will also try to set it to start automatically (this failed on Gentoo Linux).
If your system uses systemd instead, it may still work... or not (this too failed on Gentoo Linux).
When the sequence of failures is long enough, you are ready to give a try to the free client.
Free client installation¶
OpenConnect for OSX¶
Under OSX, OpenConnect is also via homebrew:
brew install openconnect
OpenConnect for Linux¶
To do (need it? please ask).
Chances are that your distribution has it prepackaged for you.
OpenConnect for iOS (Apple mobile)¶
The idea is that iTune offers an official client based on AnyConnect 4.61.
A video from Northern Arizona University may help through the next steps, using the information above. Considering the experience with the OSX version of a similar software, it is possible that the user name is required in the full format,
1 Currently, that is August 2018, there is also another version dubbed "Legacy" which is based on 4.0, and I am not talking about that one.
OpenConnect for Android¶
OpenConnect binary distribution is available via F-Droid .
Log in the VPN¶
To start using the VPN, a login must be performed. The VPN "split" mode will make sure that only the traffic to Fermilab network goes through the VPN.
The credentials for log in are:
|User name:|| plain user name (no
|Password:||Services password (same as for e-mail access, ServiceNow and others)|
Under OSX, a graphic user interface called "Cisco AnyConnect Secure Mobility Client" will allow you to enter the information above.
The user name might be required in its full glory:
OpenConnect (command line interface)¶
The simplest command to start is:
sudo openconnect --user=<USERNAME> vpn.fnal.govor equivalent. Superuser privileges are likely necessary to mess with the network configuration.
--userargument, optional, is the one like in the table above. If not specified, it will be asked interactively.
Remember that if you use that command, the first password request comes from
sudoto gain administrator privileges on your own machine.
Then, the VPN access password is requested (as in the table above).
The shell is occupied by
openconnect, unless the
--background option is specified. If not, to disconnect it is enough to hit
Chances are that your Linux operating system is distributing convenience scripts to manage the VPN... check the standard places (e.g. something in
/etc/init.d for Debian,
service for RedHat,
rc-service for Gentoo, ...).
