OSF DCE Administration Guide--Introduction

Client and Server Considerations
The following files are needed on the AIX platform only; they are kernel extensions.
On the OSF/1 platform, they are already linked into the kernel.
config_kern_ext, dtskernext, dtsloadobj, load_kern_ext, query_kern_ext,
unload_kern_ext
• DFS Clients Only
The following files are needed only if the DCE client machine is also a DFS client
machine:
dfsbind, dfsd
The following are optional on a DFS client:
bos, cm, fts
• AIX DFS Clients Only
cfgdfs, cfgexport, dfscmfx.ext, dfscore.ext, dfsloadobj, export.ext
The following subsections describe the executables that run on a DCE client machine.
3.1.2 RPC Client Programs
A DCE client contains the following programs:
• The dced daemon must run on any machine that has a DCE RPC server process that
exports an interface with dynamic bindings. The dced daemon is used to register
binding information (among other things). The dced daemon must run on every DCE
machine because on every DCE machine there are client-side daemons that export
interfaces. For example, the dtsd daemon exports the acl interface.
The dced daemon must be running before you configure any other DCE services
because DCE services need to register their endpoints with dced. Only one dced
daemon is needed on a machine. In fact, only one can run on a machine at a time
because it uses a well-known port.
Network interfaces, routing services, and other network services must be available
before DCE RPC starts. The dced daemon is started in the /etc/rc.dce file. The
/etc/rc.dce file can be invoked by other rc files, such as /etc/rc and /etc/rc.local,s o
that DCE services can be brought up each time a machine boots.
• The DCE control program (dcecp) for the management and maintenance of the DCE
RPC software. In addition, the rpccp program for operating on local registries. See
Section 3.3 for descriptions of both programs.
3.1.3 Security Service Client Programs
Every DCE client machine has, as part of the dced daemon, the Security Validation
Service. This service takes the place of the machine principal. Most principals are
