CVS on ubuntu linux

[MATI]

Hi Colleagues,

At the beginning I have to say that I have tried to look for the answers for 
my question in google - but nothing.
>From the beginning:
I use Ubuntu linux 7.04.
I have downloaded and installed cvs by command:
sudo apt-get install cvs.
After that I wrote a statement:
cvs -d /home/mati/Desktop/cvsrepo init    meaning the repository was 
created.

After that I have set variable CVSROOT:
CVSROOT=:pserver:address@hidden:/home/mati/Desktop/cvsrepo

All folders belonging to cvsrepo have 777 rights.

And now when I am trying to login:
cvs login
After this attempt I have an error:
cvs [login aborted]: connect to serwerek(127.0.1.1):2401 failed: Connection 
refused.

What am I donig wrong? Or I didn't do something at all?
How to configure and run this CVS?
When it is done I will be connecting from WIn XP onto this ubuntu server.

Thanks for help,

this is very crucial for me already.

regards,
Mati
