"I know that im not stupid"
Going to keep my mouth shut on that one, I didn't say it
So if you know 127.0.0.1 is loopback -- WTF did you bring it up for?
You manually set its IP to what? Didn't you have a post a while back asking how subnets work? Why did you mention /16 vs /8 when all you had mentioned was a loopback address?
Can not HELP you if don't know what your seeing!! When asked how your esxi is connected you state that you have NEVER even seen the networking tab? Then you throw out a loopback address and wonder why your not able to talk on a network. How are we suppose to help you with this sort of information?
edit: sc302, if he did not have nic assigned to the VM - how would it even have a loopback address?
"but I do not think it has SSH or FTP installed"
What your VM? Or some server on you schools network? If a VM - how would you not know if? You stated its "my linux server"
So are you VM's on your network or not? Do they have a IP on your segment? You do understand esxi has a firewall built into it that could be causing you some grief depending on what your wanting to do exactly as far as ssh, ftp, etc.
