In SUSE, I rlogin from machine 'a' to machine 'b' , then other users can normal login, but the root user can't be . Even enter the correct password.
Similarly, I learned from 'b' to a, the proper relationship of trust to sign. Addition, rsh can operate normally. Will what's the reason for this?
Some lgoin LOG:
