Pulse secure linux client

eugenetriguba / Install Pulse Secure on Ubuntu 20.04.md

Disclaimer: This gist is a bit outdated now. The client download page now redirects to a login page that the downloads are guarded behind. You’ll want to do a web search for a pulse secure deb file and install that now. Try: http://webdev.web3.technion.ac.il/docs/cis/public/ssl-vpn/ps-pulse-ubuntu-debian.deb. When I installed Pulse Secure 9.1R13, I didn’t need to do anything else to get it working.

To install Pulse Secure for Ubuntu 20.04, it is a bit complicated since the support isn’t great.

First, we’ll want to go through the form at https://www.pulsesecure.net/trynow/client-download/. You’ll get an email with download links to the latest versions of pulse secure. Download the Linux one with the deb file and then you can install it using dpkg from your downloads folder.

$ cd ~/Downloads $ sudo dpkg -i ps-pulse-linux-[your-pulse-version]-ubuntu-debian-64-bit-installer.deb

Now, we’ll want to go into the pulse directory and install the dependencies. We update the shell script file first to recognize Ubuntu 20.

$ cd /usr/local/pulse/ $ sudo sed -i "s/UBUNTU_VER\ \=\ 18\ \]/& \|\|\ [\ \$UBUNTU_VER\ \=\ 20 \]/" PulseClient_x86_64.sh $ ./PulseClient_x86_64.sh install_dependency_packages $ sudo apt-get install libenchant1c2a

Next, we’ll want to create an extras and debs folder inside the pulse folder.

$ sudo mkdir /usr/local/pulse/extra $ sudo mkdir /usr/local/pulse/debs

Then we’ll want to download the following debs into /usr/local/pulse/debs/ .

$ cd /usr/local/pulse/debs $ sudo wget http://archive.ubuntu.com/ubuntu/pool/main/i/icu/libicu60_60.2-3ubuntu3_amd64.deb $ sudo wget http://archive.ubuntu.com/ubuntu/pool/universe/w/webkitgtk/libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb $ sudo wget http://archive.ubuntu.com/ubuntu/pool/universe/w/webkitgtk/libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb

Next we will extract the debs into the extras folder.

$ cd /usr/local/pulse/extra $ sudo dpkg -x /usr/local/pulse/debs/libicu60_60.2-3ubuntu3_amd64.deb . $ sudo dpkg -x /usr/local/pulse/debs/libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb . $ sudo dpkg -x /usr/local/pulse/debs/libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb .

Then we’ll want to add the library path to our shell startup file and for convience, the pulse secure command can be aliased as well. Likely .bashrc if you’re using bash or .zshrc if zsh.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pulse/extra/usr/lib/x86_64-linux-gnu/ alias vpn=/usr/local/pulse/pulseUi

By default, pulse secure will have its output go directly to the terminal from which you ran it from. If you’d like to keep those separate and detach the program from the terminal when you run it, you can instead create the following alias: alias vpn=»nohup /usr/local/pulse/pulseUi >| ~/.pulse_secure/pulse/pulse-output.log &» (thanks @GreyCardinal!)

Lastly, we want to make sure to source that same shell startup file e.g. source ~/.bashrc so the changes are loaded. We can then startup the client.

If you get disconnected and the GUI is stuck in a «reconnecting» status, you can use pulsesvc -K to kill the process.

Pulse secure linux client

The usage information is also available in the readme file inside the package.

The following command gives the usage of the various options of the command line client:

The PulseClient.sh script will install the dependent packages (glibc, zlib, nss) if these packages are not already installed.

Prerequisites to Run the Command Line Client

• Pulse Connect Secure (PCS, formerly SA/IVE) IP address or hostname
• VPN user name and password
• PCS certificate (Contact PCS administrator to get certificate in DER format)
• PCS sign-in URL
• Proxy details, if applicable, (IP address/hostname, proxy username and password)

Launch the Command Line Client (initial launch OR when connecting to a new server)

Use the following command format to launch the command line client:

vpn.pulsesecure.net -u user1 -p PulseSecure

-U https://vpn.pulsesecure.net -f

• The PulseClient.sh arguments are stored internally. These arguments will be reused later, if no arguments are provided.
• Arguments storage will be overwritten if new set of arguments are provided to the script.
• In case the user does not want the password to be revealed in the terminal history, this argument can be left out. Then a prompt for password will appear.

Launch the Command Line Client with Proxy

Use the following command format to launch the command line client with proxy:

-a (-I for interactive proxy

Note : In case you do not want to reveal the proxy password in the command line arguments, then use -I (capital i) parameter instead of the proxy password parameter. Then a prompt for the proxy password appears.

Note : System proxy details will be used by command line client if proxy details are not provided as arguments explicitly.

Check the Status of the VPN Connection

Run the following command to see the status of the VPN connection:

Note : This command could take up to 30 seconds to reflect the current state of the Pulse client.

Terminate the Command Line Client
