+Install vpnc-script  
+https://www.infradead.org/openconnect/vpnc-script.html
+
+---
+### Steps to follow  
+
+* Download the latest OpenConnect tar file from below ftp location and extract it  
+ftp://ftp.infradead.org/pub/openconnect/
+
+* Run ```./configure``` command from within the extracted directory  
+
+_Got below error_  
+```
+checking for functional NLS support... yes
+checking for GNUTLS... no
+checking for OPENSSL... no
+checking for OpenSSL without pkg-config... no
+configure: error: Could not build against OpenSSL
+```
+
+Reason: The OpenSSL library is usually already installed, but you have to install the header files.  
+
+So had to install same using below command  
+```
+sudo apt-get install libssl-dev
+```
+
+Run ```./configure``` again  
+
+_Got below error_  
+
+```
+checking for LIBXML2... no
+configure: error: in `/home/raman/Downloads/openconnect-8.02':
+configure: error: The pkg-config script could not be found or is too old.  Make sure it
+is in your PATH or set the PKG_CONFIG environment variable to the full
+path to pkg-config.
+
+Alternatively, you may set the environment variables LIBXML2_CFLAGS
+and LIBXML2_LIBS to avoid the need to call pkg-config.
+See the pkg-config man page for more details.
+
+To get pkg-config, see <http://pkg-config.freedesktop.org/>.
+See `config.log' for more details
+```
+
+Same as last error, I had to install libxml2-dev  
+```
+sudo apt-get install libxml2-dev
+```  
+
+Run ```./configure``` again  
+This time command completes.  
+

+Next

+```
+sudo make
+sudo make install //to install the library

+
+On trying to connect to VPN using below command  
+```
+sudo openconnect --protocol=gp vpn.rms.com

+
+_Got below error_  
+```
+openconnect: /usr/lib/x86_64-linux-gnu/libopenconnect.so.5: version `OPENCONNECT_5_5' not found (required by openconnect)
+```
+
+Found issue at below link  
+https://github.com/dlenski/openconnect/issues/130
+
+Above issue solved using below command
+```
+sudo apt autoremove
+```
+Try connecting again  
+This time, got push notification on mobile for approval  
+
+But below error
+```
+/usr/share/vpnc-scripts/vpnc-script: not found
+```
+
+
+Followed below link to solve the vpnc-script issue  
+https://www.infradead.org/openconnect/vpnc-script.html
+
+
+Next error
+```
+Set up UDP failed; using SSL instead
+Connected as 10.5.201.132, using SSL, with ESP disabled
+/bin/sh: 1: /usr/share/vpnc-scripts/vpnc-script: Permission denied
+Script '/usr/share/vpnc-scripts/vpnc-script' returned error 126
+```
+
+Seems the script has to be executable  
+So make it executable using below command  
+```
+sudo chmod +x /usr/share/vpnc-scripts/vpnc-script 
+```
+
+Now try connecting again  
+and  
+Finally connected to VPN!
