Scoping to a NFS-mounted File

File scoping is when a process registers a file scope pattern. The name of that session is placed on a list in rpc.ttdbserverd that is associated with the registered file. When a file-scoped message is sent, the ToolTalk service retrieves the list of sessions for the file and forwards the message to each of the sessions on the rpc.ttdbserverd list for that file.

To scope to a file that is NFS-mounted on the machines involved requires a file system to be NFS mounted on all the systems and rpc.ttdbserverd to be run on the NFS server.
