I am using putty to connect to a unix box machine the issue is that every time i need to enter the credentials of the servers (unix box) , please advise is there any way i can configure putty so that only i need to eneter the user id of the server and password is automatically pass to the unix box machine , on exploring i have to come know the concept of SSH connection , please advise how can i configure the SSH connections on my putty , in short i want to establish password-less connection through putty

An option would be to convert your ssh private key to putty key format and to use the putty utility pageant to keep the key in memory. Don't forget to use a strong passphrase to encrypt your private key..
