Rhosts Mechanism - Computer Definition
The Berkeley rlogin utility allows remote users to obtain access to a system without supplying a password through the .rhosts mechanism, a list of host names and/or IP addresses considered to be trusted. Because it is considered to be highly insecure, experts recommend replacing this service with the more secure and encrypted SSH. If rlogin access is required, the service should be protected by the use of TCP Wrappers.
