Unable to login using .rhosts

[Matteo Landi]

Everytime I try to login via rlogin using the .rhosts file, I get back a "Permission denied" message, and I'm prompted for the password.

I checked the error messages from /var/log/auth.log, and it seems a few libraries are missing from /lib/security. In particular I needed to symlink a few of them before succeeding with the no-password login:

# ln -s pam_rhosts.so pam_rhosts_auth.so
# ln -s pam_unix.so pam_unix_session.so
# ln -s pam_unix.so pam_unix_acct.so

Is this a known problem or not?

Hope this could help.

Hi,

Which package did you install as rsh server ? I got the same problem with "rsh-server" package (Ubuntu install this one by default) on Ubuntu Server 10.04
I replace it with "rsh-redone-server" and it solve the problem.
Regards,

Yes, indeed, this is a problem with the rsh-server package. The problem is that per libpam-modules:

pam (1.1.0-3) unstable; urgency=low

  * pam_rhosts_auth module obsolete, symlink removed

    The pam_rhosts_auth module was dropped upstream prior to the lenny
    release and a compatibility symlink provided in the libpam-modules
    package, pointing at the new (and not 100% compatible) pam_rhosts
    module. This symlink has now been dropped. If you still have
    references to pam_rhosts_auth in your /etc/pam.d/* config files, you
    will need to fix these, since they no longer work.

    For information on using pam_rhosts, see the pam_rhosts(8) manpage.

Yet in /etc/pam.d/rsh from rsh-server:

auth required pam_nologin.so
auth required pam_env.so
auth required pam_rhosts_auth.so
account required pam_unix_acct.so
session required pam_unix_session.so

As you said, I installed rsh-server.
Removing the symbolic links, the package, and reinstalling
rs-redone-server fixed the problem.
Regards,

ps. sorry for the late answer.

Important here to note that rsh-redone-client does not provide rcp, whereas rsh-client does.
So the working combination is rsh-redone-server with rsh-client.
Anything else doesn't fully work with rhosts.

Thanks a lot -- I've been banging my head against the wall (I've used passwordless rsh for 20 years)

It worked on old ubuntus and new ones -- not that one!!
