$ wget -q http://kb.arubacloud.com/files/tar-gz/forticlientsslvpn_linux_4-0-2281-tar.aspx -O fortisslvpn.tgz && tar -xzf fortisslvpn.tgz
$ cd forticlientsslvpn && ./helper/setup.linux.sh

Press Ctrl+C, Agree Their License (1st time only) & then connect to VPN by:

$ yes | ./forticlientsslvpn_cli --server sslvpn.server.com:10443 --vpnuser a_user > /dev/null

If you wish run with GUI you may need to install

sudo apt-get install libgtk2.0-0:i386

Troubleshooting

Error - Peer's certificate is not valid. action is 1

Your endpoint SSL certificate is not trusted by your local machine. Firstly, create trustedstore hidden directory

$ mkdir ~/.fctsslvpn_trustca

Secondly locate trusted stores on your machine and copy to Forticlient trustedstores location

$ locate cacert
$ cp /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts ~/.fctsslvpn_trustca
$ cp /opt/Citrix/ICAClient/keystore/cacerts/QuoVadis_Root_CA* ~/.fctsslvpn_trustca

Run the connection command

$ yes | ./forticlientsslvpn_cli --server sslvpn.server.com:10443 --vpnuser a_user > /dev/null
