SSH WITHOUT PASSWORD

I tested on this my local servers
os = both are installed with Centos 5.2`
client ip address = 192.168.1.89
server ip address = 192.168.1.88

steps:
1.First create keygen
2. copy it to the remote server ./ssh/ directory
3. edit the file /etc/ssh/sshd_config and change the value   """ StrictModes no ""
4. restart the sshd service ...

thats it ..
