64-bit VPN – How to Install Juniper VPN on Ubuntu 14.04 LTS

If You got Juniper SA older than 7.3, then You need to install both 32 and 64 bit. You need to launch java 32 bit to run network connect.

You need to install libxtst6:i386 package to run 32bit version of java on 64 bit system:

sudo apt-get install libxtst6:i386 libxrender1:i386 libxi6:i386 libncurses5:i386 libncursesw5:i386 libncurses-ruby:i386

(if it fails, then install whole ia32-libs package).

install 64 bit version in /usr/lib/java/jre/

install 32 bit version in /usr/lib/java32/jre/

then do following:

sudo mv /usr/lib/java/jre/bin/java{,.orig}

sudo gedit /usr/lib/java/jre/bin/java

file should look like this:

#!/bin/bash
if [ "$3" = "NC" ]
then
  /usr/lib/java32/jre/bin/java "$@"
else
  /usr/lib/java/jre/bin/java.orig "$@"
fi

Then You need to make it executive:

sudo chmod +x /usr/lib/java/jre/bin/java

Then use update-alternatives to install appropriate version of java:

sudo update-alternatives --install /usr/lib/mozilla/plugins/libnpjp2.so java_plugin /usr/lib/java/jre/lib/amd64/libnpjp2.so 10
sudo update-alternatives --install /usr/bin/java java /usr/lib/java/jre/bin/java 10
sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/java/jre/bin/javaws 10

If You have encrypted home folder, since 13.04 there is nosuid added to mount options, so You can move .juniper folder outside of encrypted home, ie: /opt an the create a symlink:

cd ~
mv .juniper /opt
ln -s /opt/.juniper .

Determine if You have installed java plugin in Firefox (in add-ons -> plugins). If So, You should be ready to go.

I took recipe from that page: http://ubuntuforums.org/showthread.php?t=232607&page=51

But if You want to run openjdk, then follow those steps:

sudo apt-get install openjdk-7-jre icedtea-7-plugin openjdk-7-jre:i386 ia32-libs
sudo mv /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java{,.orig}
sudo gedit /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java

It shoul look like this:

#!/bin/bash
if [ "$3" = "NC" ]
then
  /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java "$@"
else
  /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java.orig "$@"
fi

Make it executive:

chmod +x /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java

So far it worked for me.

OK I think I understand this one now. I created a Windows VM, installed the Cisco client and configured it with my credentials. I got in to the VPN with no problems but I noticed some interesting behavior that perhaps is not handled by many Linux clients. I had just changed my Windows password on the target Windows desktop box inside the VPN, which is what I think triggered this. When I logged in using Windows 7 and the official Cisco client it prompted me not once but TWICE for an RSA passcode. The second time I was specifically prompted for the NEXT passcode. Short term work-around then is to log in once from a Windows box at the remote side each time you change your Windows password. I wonder how many headaches this has caused?
