How to generate keys by ssh command

Finally get the clue with the help of Zeba's website.

1. On the machine you want to use to call another machine, say A ->B
We would like A to ssh B without inputing the password.

2. In A machine, type the command: ssh-keygen -t dsa -b 1024
no key phrases

3. Copy the key to machine B by: scp
id_dsa.pub user@192.168.X.X:/home/user/.ssh (this might be changed according to different setting)

4. cat id_dsa.pub >> /path/.ssh/authorizedkeys

5. Now you can ssh B without password from A.

for details I need to read more on security authentication...
