I am currently trying to download a few server versions of Linux operating systems in order to compare which is best in terms of memory usage etc. I am running these off of the vmware program and have managed to download the ubuntu server and desktop ok. However, I cannot seem to find any version of red hat that isn't free, or indeed the server versions of Mint and Fedora. I have managed to download Fedora only to discover it was the desktop version which doesn't have a terminal and any time I have downloaded a version of Mint(any version at all), when I run it on vmware player, it tells me that vmware player does not recognise the operating system and then nothing else happens. I have been sure to download the iso file for these as well but with no success.
Does anyone know then any links where I can download the servers for Mint, Fedora and Red Hat that actually work? it is very frustrating that it hasn't worked so far.
