RSH support is not available from Windows NT
servers. Even if X clients are installed on NT, RSH
support must be available from other server(s) for the X
Manager to be able to launch them.
The X Manager is the terminal’s interface to RSH; on the server the following must
typically must be configured for RSH support:

For exact details refer to the manuals on your server.
First,
rshd
(or the equivalent) must be configured to respond to requests for
application launching. Do this by modifying
inetd.conf
as appropriate for your
system, or by running the appropriate system configuration tool.
Second, the server must be able to resolve a name from the IP address of the
terminal. If the terminal IP address-to-name mapping is provided by DNS, nothing
needs to be done. Otherwise, the server’s
/etc/hosts
(or equivalent) file must be
modified to contain the name that the terminal reports it has for that IP address. If
DHCP services are used, but dynamic DNS (DDNS) is not in use, it may not be
possible to construct a static table that correctly matches name and current IP
addresses. If the terminal has a domain name, the name that matches the
terminal’s name will typically have the domain name as well.
Third, you must decide on how you are going to run the program. There are several
approaches. There can be a one-to-one relationship for all terminal users to server
users or there can be a many-to-one relationship for all terminal users to server
users. The approach chosen will have many implications in the areas of security
and privacy, and the choice should be made carefully. In the first case, you will
need to provide accounts on the server for every terminal user. In the second case,
you will need to provide a generic account on the server and have all X Manager
sessions go through that account. For the one-to-one case, the entry in the X
Manager

field should be

. For the
many-to-one case, the entry should be the chosen account name.
After creating the account or accounts on the server, the .
rhosts
file in that
account must contain the names of all users and terminals allowed to use that log
in. The .
rhosts
file
must
be owned by the server user, and contains lines of the
form
