remshd: login incorrect - due to alternate host name

[Jim Mills_4]

I get the login incorrect and have followed many of the suggestion in the forums (thanks all) and have figured out that what is happening is that the server that one can't rcp from is using the wrong ip address.

We have MC-Serviceguard, thus are running packages with their own IP addresses. This works fine on our production boxes, but for some reason when rcp'ing from the development box, the other machines are seeing the ip (and name) of the first package instead of the host and it's ip address.

In this example, the ip/host is 10.28.38.225/t21aldu1, and the package is 10.28.38.14/t21aldrt

Yet, on the other boxes (after running inetd -l and tail -f /var/adm/syslog/syslog.log) I saw that the incoming ip/host was the lan2:2's 10.28.38.14/t21aldrt

Any ideas why this is happening? I'm sure there's something on t21aldu1 I need to fix.

Make sure that ip and user entry in .rhosts file in the user's home directory is correct. I think the remote machine is not resolved as you think it's resolved, that's why you get "login incorrect" message.

Looks like it had something to do with the subnet mask...but you were on the right track Alex as it was "easier" to use the virtual ip address for name resolution.

Thanks for helping out.

HP and I found the solution of the subnet mask.
