VMware has no native VSphere client for Linux hosts and VMware pushes its users to use the VMware web client. There is a workaround for this but it doesn’t give you the full benefits of using a full pledge VSphere client in Windows, however it gets the job done.
To access VMware ESXi console from ubuntu download the free VMware Player for Linux 64-bit . Move it to your preferred install folder, give execution privilege and install. Follow the installation prompt all through out the process.
mv ~/Desktop/ ~/ chmod u+x VMware-Player-7.1.0-2496824.x86_64.bundle ./VMware-Player-7.1.0-2496824.x86_64.bundle
After the installation, run the command:
vmplayer -H <ESXi-IP-ADDRESS-> -U <USERNAME>
The VMware player window launches on your screen and requests the password to the host. Once you are logged in you will see a list of available virtual machines. If the VM guest is not powered on and you open a console to the VM guest it will be powered on.
