How to connect to a Juniper VPN from Linux

  • 772

The Windows users have a new client "Juniper Pulse" to connect to the Juniper VPN server.

On Linux, what VPN client do we have to connect to that Juniper VPN, with maximum compatibility?

Please mention the necessary parameters that have to be provided.

vpn linux juniper

    And my favorite method (no java applet required):

    Presumably:

    -

    REALM=$(wget -q --no-check-certificate -O - 'https://some.site.com/dana-na/auth/url_default/welcome.cgi' | sed -n 's/.*<input\( [^>]*name="realm" [^>]*\)>.*/\1/p' | sed -n 's/.* value="\([^"]*\)".*/\1/p')

    After you login, download the following jar (should be done one time only):

    https://some.site.com/dana-cached/nc/ncLinuxApp.jar

    and unzip it to ~/.juniper_networks/network_connect

    Get some new libraries for your 64bit machine yum install glibc.i686 zlib.i686 nss-mdns.i686

    Go to ~/.juniper_networks/network_connect and

    sudo chown root:root ncsvc
sudo chmod 6711 ncsvc
chmod 744 ncdiag
chmod +x getx509certificate.sh

    Get your certificate:

    ./getx509certificate.sh some.site.com company.cert

    And connect:

    ./ncsvc -h some.site.com -u username -p password -r REALM -f ./company.cert

    For some sites I noticed that you also need to put the -U switch:

    ./ncsvc -h some.site.com -u username -p password -r REALM -f ./company.cert -U 'https://some.site.com/dana-na/auth/url_default/welcome.cgi'

  2. The OpenConnect VPN client has (nascent) support for Juniper SSL VPN.

    See the announcement at http://lists.infradead.org/pipermail/openconnect-devel/2015-January/002628.html

    Edit 2015-02-02:

    The Juniper support is coming along nicely now and is definitely ready for more testing. It's reached the point where we're happy to admit to its existence on the OpenConnect web site: http://www.infradead.org/openconnect/juniper.html

  3. What I usually do is use openconnect, it has to run as root, from the terminal window and you have to use the --juniper flag like this:

    sudo openconnect --juniper http://your.vpn.server.here

    It will ask for your user name and password and will connect you to your vpn.

    The only caveat is that the terminal window has to be open all the time and it may drop once or twice in a day, you have to re-connect.

  4. Network-Connect is the Old Juniper VPN. It is no longer used/shipped by juniper, everything is now Pulse secure. The information on this site is old. Pulse Secure is not supported on Linux.

  6. On Ubuntu 15.10:

    • sudo apt-get install icedtea-7-plugin openjdk-7-jre:i386
    • sudo ln -s /usr/bin/update-alternatives /usr/sbin/ (this may already exist)
    • sudo apt-get install libstdc++6:i386 lib32z1 lib32ncurses5 libxext6:i386 libxrender1:i386 libxtst6:i386 libxi6:i386

    Then connect to your VPN as you would normally through the web interface. You'll need to allow the IcedTea plugin to run in your browser (I used Firefox) when it prompts you. There are also a number of prompts to trust software from a remote site, and it pop up a terminal for your password.

  7. I believe this is answered on Juniper's forum here - specifically for Network Connect (I'm assuming that's what you're wanting to do). They have excellent screenshots, etc to help you through the process (Five steps).
