Installing ESXI v.6 VMware Tools on Debian Linux

VMware Tools ESXI server v.6 Easy installing steps,
There is no official deb installer available, 

ESXI Server v. 6 VMware Tools on Debian Linux.
Instead you need to install it manually.
Here is some idea how could you do it and it works.... :)

• In vSphere Client, use the command Guest – Install/Upgrade VMware Tools (it “inserts” the VMware Tools ISO in the CD drive of the guest)

• Open console/SSH to the guest as root (or use sudo as needed)
• mount /dev/cdrom /mnt
• tar xzf /mnt/VMwareTools*
• umount /mnt
• apt-get update
• apt-get install gcc make linux-headers-$(uname -r)
• cd vmware-tools-distrib
• ./vmware-install.pl4096
• cd
• rm -rf vmware-tools-distrib
• reboot
