Q. Under Windows it is pretty easy to find out VMware server version. How do I find out remote vmware server version using ssh client running under RHEL / CentOS Linux 5.x?

A. You need to use the vmware command, which starts an Intel X86-based virtual machine. Depending upon your hardware configuration, you can run a number of virtual machines simultaneously. The -v option display the program version then exit without starting a virtual machine. Type the following command at shell prompt (following command should work under any Linux distribution):
$ /usr/bin/vmware -v
OR
$ ssh user@remote.rhel-server.com /usr/bin/vmware -v
Sample output:

VMware Server 1.0.5 build-80187

For further information refer to man page:
$ man vmware
