rlogin (remote login) 1  Securing VMware Virtual Infrastructure with Centrify's Identity and Access  ... Rlogin (remote login) is a UNIX command that allows an authorized user to login to other UNIX machines (hosts) on a network and to interact as if the user were physically at the host computer.
rlogin starts a terminal session on the remote host specified as host. The remote host must be running a rlogind service (or daemon) for rlogin to connect to. rlogin uses the standard rhosts authorization mechanism. When no user name is specified either with the -l option or as part of username@hostname, rlogin connects as the user you are currently logged in as (including either your domain name if you are a domain user or your machine name if you are not a domain user).
