i have edited /.rhosts and /etc/hosts.equiv to be "+"
my NeXT box (NeXTStep 3.0) allows me to rlogin, but prompts me for a
password first. The SUN boxes on our LAN do this when they are freshly
loaded with the OS, but the aforementioned file editing does away with
such annoyances. what's up with the NeXT?

Have you set the $HOME/.rhosts

Make sure that the host that you're rlogging in from is in your
.rhosts file in the account on the machine that you're rlogging in
to. To find out what machine you're rlogging in from, type "who".

Been there, done that, no help. My sytems still prompts me for a
password. I just gave up and assumed it was a quirk of the system.
Any advice would be apreciated.

rlogind uses the ruserok() call to read .rhosts and /etc/hosts.equiv
and report whether or not it needs to ask you a password. rlogind
usually runs as root (it has to). Therefore, a process running as
root needs to be able to read your .rhosts file. In an environment
where your .rhosts file is NFS mounted and the NFS directory isn't
exported from the server with the -root option, root may not be able
to read your .rhosts file, and it will fail. So, make sure that
root can read your .rhosts file. This may require making your home
dir at least mode 711, and your .rhosts file mode 644 if your
directory is on a remote NFS-mounted disk.

The original question was about a NeXT, but this is also in
comp.sys.sun.admin, and later followups didn't mention what
system they were using... so, FWIW, Sun's (actually, BSD)
ruserok() does a seteuid() for exactly the reason you mentioned.
It would be interesting to see if his ruserok() is broken.

Note that some Security packages (BoKS from DynaSoft in particular) actually
take over control of functionality such as 'ftp', 'rlogin', 'telnet', etc.
To give an example, BoKS can be configured to NEVER allow remote access without
a password. In this type of installation, whether or not you have a .rhosts
file is ignored -- BoKS sees if a valid "access route" exists for USER "X"
from system "Y" to system "Z" and, even if you ARE allowed to 'rlogin', you
still must supply the correct password.

If you're running DNS, make sure that you put a FQDN in the .rhosts
file, i.e.'axalotl.demon.co.uk', not just 'axalotl'.

check hosts.equiv to make sure that the host is listed. If this is from
a portmaster or a terminal server

I don't know if anyone suggested this, but the .rhosts file must be owned by
the user, and writeable only by the user, otherwise it will be ignored.

I've had a similar problem with my SINIX system V.4(Siemens Nixdorf).
You should be sure that the machine name You use in hosts.equiv or
rhosts is the first name in /etc/hosts e.g. NOT an alias

maybe that's it. Maybe it's not.

I had this same problem. This is the most likely answer. If you are running DNS
either update the /etc/hosts file or make sure that you use FQDN's.

Only on some systems does it require .rhosts to be mode 600. Many
allow 644 because of the NFS problems talked about in other articles
here.

Who said anything about 600, 644 meets the cirteria of "writeable only by
the user".

in sunOS 4.1.3 and above you need the password
sunOS 4.1.2 allowed rlogins without them.
that's what i was told and:

i can rlogin <our 4.1.2 machine> without a password from the 4.1.3 machine
but rlogin <4.1.3 machine> from the 4.1.2 machine does require a password
