Hi Trevor,
thanks for taking time to respond.
For the console (ie. the monitor/keyboard attached to your server) http://wiki.contribs.org/SME_Server:Documentation:Administration_Manual:Chapter6 Section 6.2. Accessing the Linux Root Prompt
In my response to Cactus I quoted from this very section (Chapter 6, Section 6.2. of Admin Manual):
The password for the "root" user is whatever password is currently set for the administrator of the server. Note that this is the same password as that used by the "admin" user account.
I used root as username and admin's password but it did not worked.

I had CAPS LOCK on when I tried to go to root from console

No wonder that it refused password!
Nevertheless today I was able to see for first time in my life
[root@server1 ~]#

I used SSH over local network.
As per cactus' comments, nearly everything should be able to be administered through server-manager, which is available from your notebook plugged into the local LAN. If you want to access the server-manager or console remotely, please read the Security section of the Administrators manual.
Security warning noted, but I really could not make out how to start Midnight Commander except to start first Command Prompt
Yes I know next to nothing about command line and i would like to use something else like this:

If you are not familiar with working from the Linux prompt, you may be interested in trying a file management tool called Midnight Commander. It allows you to perform many file operations through a menu-driven interface. Simply type mc at the command prompt. Press the function key "F1" for help and "F10" to quit.
but as you see to be able to use Midnight Commander I have to go to command prompt first Confused
Quote above is from Admin Manual section 6.2. as well.
So after connecting by ssh i typed mc and ... voila:
Left File Command Options Right
l<q~qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqv>kl<q~qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqv>k
x Name x Size x MTime xx Name x Size x MTime x
....etc.
Thanks for your help.
I am sure that I will be back soon with more

I already have one but this is more for contribs so I will post it there.
