(Note: This is under Ubuntu Dapper.)
First thing was to get the VMWare Server files from VMWares site. Follow the directions for registering for an account, and don't forget to get the serial number.
Once you have downloaded the tar file, extract it to a temporary location. Once extracted, you will need to get a few pre-requisite packages for Ubuntu. To get these packages, type in a terminal window:
sudo apt-get -f install gcc g++ linux-headers-`uname -r` build-essential xinetd
or, if like me, you already have the kernel headers installed, just type:
sudo apt-get -f install build-essential xinetd
The build essential option probably isn't necessary, however I used it, it worked, so thats why I am documenting it that way.
Once done, go into your temporary directory, and run the vmware-install.pl file with:
Follow the directions. Once completed, the program will show up under the Applications/System Tools menu as “VMWare Server Console”.
-Note: When I initially tried to do the install, I did not have the xinetd package installed. This caused the configuration of the kernel modules to fail. Thanks to this Ubuntu forums message, I was given the above command to get the xinetd package, which is why I kept the build-essentials flag in.
