My problem was:
I have just taken over responsibility for a bunch of DEC Alpha workstations
and have noticed a problem with rlogin from one of the DECs to any other
unix machine on the network. We have a mix of OSF3.0 and 3.2c as well as
several hundred other unix workstations all running NIS. They seem to have
installed ALL subsets,including C2 security, on each Alpha since each
machine has lots of disk space. The C2 security has been installed, but
doesnt appear to have been configured. On many of the 3.2 machines I can:
rlogin cc0174
and it works properly. But, on cc4060 if I do:
rlogin cc0174
it ALWAYS prompts for a password, even I put my user name in /etc/hosts.equiv
on cc0174.
(Remember, we run NIS so the /etc/hosts.equiv contains an NIS map with all
trusted users, including myself).
I'm stumped. I admit that I don't know anything about C2 security and that
we dont use it here. Does anyone out there have any clues as to why
this one 3.2c machine always prompts for a password when rlogining in to
other machines, while the rest of the 3.2c alphas do not do this. I'll
summarize. Thanks in advance.
The answer was suggested by several people, but Spider Boardman summed it
up well:
"Anyway, it might help if after logging in with the password from
cc4060 to cc0174, you use 'who -M' to see where you've logged in
from as cc0174 sees it. It's almost certainly a problem with
mapping the address and name of the cc4060 machine at cc0174."
I thought I was certain that IP mapping was working just fine but it
turns out when they installed a second ethernet adapter in the machine,
they forgot to include it's ip and name in the netgroup file on the NIS
server. Oooops. So, when rlogining into another machine, cc4060 appeared
as cc0060, which was not in the netgroup list. The problem turned out
to be unrelated to the C2 subsets being installed. Thanks again for the
help :)
