Class R-Command
Detailed Description The rlogin service is running. This service is dangerous in the sense that it is not ciphered - that is, everyone can sniff the data that passes between the rlogin client and the rlogin server. This includes logins and passwords.
You should disable this service and use openssh instead(www.openssh.com).
