Install kerio vpn client on centos 7 amd 64

this tutorial show you how to install kerio vpnClient on centos7 64bit. kerio vpnClient does not have any .rpm official version! I tried install it during one week.

1. first of all download kerio-control-vpnclient-###-linux-amd64.deb from http://www.ryadel.com/en/kerio-control-vpn-client-all-versions-direct-download-links/ which contain many version of kerio-control-vpn-client or everywhere else.

2. after download kerio-control-vpnclient-###-linux-amd64.deb we must convert it to .rpm package, to convert .deb to .rpm use alien which convert packages ( https://packages.debian.org/unstable/source/alien )
