What is the purpose of /etc/hosts.equiv

Dear List,

I have a customer with a client server application. The Server is running Fedora 26. The Clients are Windows.

The server has DDNS configured and have all the MAC addresses of the workstations (and printers) are locked into /etc/dhcp/dhcpd.conf. Named-chroot has all the workstations address in both forward and revers tables (populated by DDNS). "host" finds everything forward and reverse, with and without the domain name attached.

The vendor requires a /etc/hosts.equiv file with the names of the widows workstations in it.

Why? (I asked him and he did not know. He said that was the way it has always been.)

Many thanks, -T

"/etc/hosts.equiv - list of hosts and users that are granted "trusted" r command access to your system"

So maybe the vendor is using an r command I can not find. The client is talking to a service on port 1100. And the client machines to talk to a lot of services (dns, dhcp, time, etc) that do not require a hosts.equiv. So, any light you can share on the subject would be appreciated.

The 'r' commands are rsh, rlogin, and rcp as provided by the rsh-server package. They are mostly obsolete and the replacement is ssh and scp, which don't use /etc/hosts.equiv.
