hi...
i've got an "access denied" issue with rsh on one of my boxes (and before we
start, no "use ssh" comments.. rsh is what i'm dealing with for now!!)
i've got a few boxes in my network, and i can successfully rsh into them
with no issue. however, on one box, i can't access it using rsh, and i'm
running out of things to try... kind of curious.
i can login using rlogin.
i've modifed the /etc/pam.d/rsh,rlogin files, along with the /etc/securetty
file. i've also changed the /etc/xinetd.d/(rsh,rlogin)files. as far as i can
tell, nothing else has been changed...
the curious thing. as far as i can tell... the files on the system that
doesn't work, are the same as the files on the systems that are allowing rsh
to occur...
the err i'm getting in the /var/log/secure is:
Jun 23 22:16:09 lserver5 userhelper[2186]:

server = /usr/sbin/in.rlogind

}
i've been searching across the net for the last day or so, so i suspect that
the solution is staring at me and i'm missing it!
is there a way to debug this from the server side? is there a way to turn
off authentication.. Is there a way to turn off/disable securetty...
so... any thoughts/comments/things to check would be greatly appreciated....
thanks
