Samba root user log in

I am using your How to SAMBA (Domaincontroller) Server For Small Workgroups With Ubuntu 5.10 "Breezy Badger"


I installed Ubuntu sever on my harddrive than I

Log in with the user name and password I set up than I

put in sudo passwd root

Than su for my password

than it asks me a Enter new UNIX Password so I enter another password

than it asks me to reenter which I do,

Than it says password updated successfully

admin@srv2:~$

I try to do the /etc/network/interfaces

but it says Premission denied

So I am not sure where I got off track

 

After it says password updated successfully you must run

Code:

su

to become root. After that you can edit /etc/network/interfaces.

 

OK but now

I was able to log on as root user but it is telling me Permission denied when I attempt to enter /etc/network/interfaces

 

Please excuse my ignorance, but what is a commandline editor? is vi or joe something that I would have to download and install? and if I did how would I use it?

 

Normally vi is already installed. You use it like this: http://www.howtoforge.com/faq/12_15_en.html
