My nameserver is now working in the vps and it seems that my domains are now pointing at him, i have created inside 4 accounts, logged in and out from multiple users, all seems fine, made a few tests in the users accounts, such as try the browsers, place testing homepages, now i am going to try some ftp settings and also email accounts.
I really enjoy Putty now, thanks to you guys, Locutus and andreycheck, since day one of this post you guys were great and helped me a lot, i learn now how to make the installation, and i am a complete newbie and till now all my tests seems ok, it is in fact a better and cheaper solution for any user, and i really like the enviroment, simple and fast.
With this, i learned a new coding experience (thanks) and i made my vps running! (thanks again)!
I cant wait now too explore more things on it.
