Before configuring a Gateway Server machine, you must do the following:
vConfigure a DCE cell that includes DFS.
vConfigure each machine that is to become a Gateway Server as a DFS client and an NFS server.
vEnsure proper synchronization among the system clocks on machines that are to become Gateway Servers, machines configured as NFS clients that are to contact the Gateway Servers, and machines in the DCE cell to be contacted. You must keep the system clocks on these machines synchronized at all times.
Configuring a Gateway Server Without Enabling Remote Authentication
Perform the steps in this section to enable DCE authentication from a Gateway Server machine without enabling it from NFS clients that contact the Gateway Server. Users can authenticate only by issuing the dfsgw add command on the Gateway Server machine (or by having a system administrator issue the command for them).
1.Log in as the local superuser root on the machine.
2.Install the binary file for the dfsgw command suite in the directory dcelocal/bin on the machine. The dfsgw command suite provides a local interface to the authentication table maintained on the Gateway Server machine. Commands in the dfsgw suite can be used to add, delete, and view mappings in the authentication table. (See “Authenticating to DCE from a Gateway Server Machine” on page 21, “Determining Whether a Specific User Is Authenticated to DCE” on page 22, and “Displaying Information About All Users Who Are Authenticated to DCE” on page 22 for information about using these commands.)
3.Export the DCE global root directory, /..., via NFS. This is typically accomplished via the share command; the exact command and procedure depends on your vendor’s implementation of NFS, as detailed in the vendor documentation.
The Gateway Server machine is now configured to provide DCE authentication only via the dfsgw add command. Repeat these steps on each DFS client that is to be configured as a Gateway Server in this manner. If you later decide to allow users to authenticate to DCE from NFS clients that contact the Gateway Server, simply perform the steps in “Configuring a Gateway Server and Enabling Remote Authentication” on page 7 on the Gateway Server machine.
