Why can't rlogin

[hangyu]

In have two RH Server , root user can rlogin from host A to host B , but other user can't , I have already update the .rhost of host B , I am wonder why root can but user can't , can advise what is the possiblity ? thx.

on host B edit the file /etc/hosts.equiv and add the hostname of host A.

rlogin is insecure- i.e. why not to use ssh?

User should be owner of his .rhosts, permissions should be 600.
