But as you said Bakunin it doesn't asks for password which is a security hazard.
Errrm, no.
The problem is not the failure to ask for a password. rlogin in fact asks for a password if the user/host is not mentioned in the .rhosts-file. And if you use ssh and have exchanged the keys it does not ask for a password either.
The problem is that rlogin (like telnet and all the other classical connections) transfer all the data without any encryption and therefor you can find out the password sent (and all the other things done) as a third party by listening to the traffic on the line. While ssh encrypts the whole communication so you could listen to it and still not understand.
It is a common misconception that more passwords create more security. True, a password will identify someone, but having to enter a password over and over doesnt make the system more secure than having to enter it once. In fact having to remember several passwords will reduce the security because as the number of passwords increases people are more likely to write them down somewhere where they can be found by intruders.
I hope this helps.
