Is there any versions of Linode or Slicehost free or any equivalent free.
Is it in fact a must to have these programs to connect a VPS set-up.
Is it possible to connect with such as Putty only.

Using Ubuntu 8.04.

What?

Great answer. Thanks.

Your question(s) do not make sense. Can you clarify instead of being sarcastic?

No, there are no free (as in cost) VPS providers, and if there are I wouldn't trust them.
What programs? Connect what to a VPS setup?
Connect to what with PuTTY? No, PuTTY isn't the only program you can use to connect to an SSH server.

I know the many VPS and Putty are all free but that is not my question. Can a VPS such as Nginx be connected to the WWW with Putty only and not having to use such as Linode to connect with as they are to pay for.

Nginx isn't a VPS, Nginx is an HTTPD or Web server. And you don't use PuTTY to connect to Nginx, you use a browser such as Firefox. And you don't need a Linode to run Nginx, you can use any server you want to, even one in your basement.

What exactly are you trying to do? You're still not making sense.

OK, I have downloaded Nginx with all the extras and it works as I get the welcome part on the laptop it is installed on and all other laptops I have on the same router. I need to connect it to WWW so I can see my website. The howto I have followed
Install NGINX (better than Apache or Lighttpd) - VPS Bible Pt 11 - GUVNR *

has about 20 parts to it and more or less states that Linode is needed to make the connection with the use of Putty and CLI. Linode is to pay for Putty etc. is free. What I need to know is Linode really necessary.
