hey the mistake was in permission for .ssh/authorized_keys, now i could enter for system 'a' to 'b', but when i tried from other ways i.e 'b' to 'a' its not working.....

ok, you were supposed to replace "systemb" with the address of systemb. You didn't give us the name so I couldn't give it to you.

To make it go the other way, just repeat the process in reverse. If you want more help, you need to post the output of ssh -vv.
