If you want to connect to JET machines via VPN you can use Virtual Machine. There are few benefits here:

1. your network traffic doesn't go via JET's VPN - only one from Virtual Machine
2. you don't have to install all the components by yourself

1. Download and install Virtual Box

https://www.virtualbox.org/wiki/Downloads

2. Make sure to install Extension Pack

VirtualBox 5.2.6 Oracle VM VirtualBox Extension Pack - you can find it on Download page

3. Download Virtual Machine from Gateway

$SWITMDIR/resources/jet/JETVPN.tar.gz

4. Install JETVPN inside Virtual Box

5. Start the machine

6.

7. Log in

user: jetvpn
pass: jetvpn

8. Start two Terminal sessions

Start VPN tunnel

1. in Terminal 1 make sure to change your user to root and establish tunnel

   1. change user to root

      

      su -
      # password for user root is: jetvpn

   2. start tunnel by calling script ./connect.sh

      ./connect $USER_NAME         # user name is exactly the same as one that you use in JET
      ...
      ...
      VPN account password:

   3. once asked for password provide it in form

      PPPPKKKKKK
      # where 
      # PPPP is your PIN code
      # KKKKKK is a value from your RSA SecurID

   4. Tunnel should be up and running
