rshd, rlogind, .rhosts question

[Wojciech Puchar]

i use this widely with NetBSD and now try with FreeBSD

rlogin/rlogind works the same - all OK. if host is entered in .rhosts then 
it logs in without password

rsh -l login host command worked fine too in NetBSD same way - no asking 
for password if .rhosts consist of my host and user name.

in FreeBSD rsh doesn't work that way, always ask for password.

what's the difference? how to fix it?
