Yes. This file indicates which machines should be trusted to allow an
incomming rsh conection.

I guess that's hosts.allow. Check that you use the net address and the
subnet netmask, not the machine IP address.

No. The /etc/hosts file is like a list of aliases to ip address.
The /etc/hosts.allow, as its name says, is used to specify which hosts
can access to wich services.

You can allow an entire network to access a service. In every node you
use from a network you should add something like this:

in.rshd: Your_network_address/Your_subnet_mask
in.rlogin: Your_network_address/Your_subnet_mask

If you don't know the network parameters, ask your network admin.
