when I am trying to access the server through ssh it says:

ssh: connect to host xx.yyy.zzz.x port 22: Connection refused

and on the server in auth.log it shows following log entry:

Address xx.yyy.zzz.x maps to xx.yyy.zzz.x.static-pune-vsnl.net.in, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!

I have created a user account for that user and it is also in enabled status.

Requested info

1. It is Ubuntu 11.10


2. It is configured as SSH Server using openssh-server


3. I am trying to connect to this server using Putty from Windows 7 i.e. My Desktop


4. I have also asked this in superuser as per the request of @zpletan and link to that question is given below.
