NAME
dced - DCE Host daemon
SYNOPSIS
dced [-ifh] [-w route] [-b|-p|-s] [-e|prot_seq...]
OPTIONS
-h Prints the dced usage and exits.
-i Initializes the dced databases and ACLs and exits. If the
databases exist, this option displays an error. See the
list of databases in the FILES section.
-b Starts dced in bootstrap mode with the endpoint mapper
service and ACLs. This mode means it may need to wait
for other daemons such as secd and cdsd before it can
perform its own initialization.
-c Starts dced so it does not require DCE privacy encryption
for remote key table management. The default is to use
DCE privacy encryption.
-e Starts dced without the endpoint mapper service. No
protocol sequences are valid for this option.
-f Starts the dced process in the foreground. The default is
for dced to run in the background.
-p Purges the existing machine context and removes the bindings
file before starting.
-s Starts dced without the security validation service.
-w Sets the routing for serviceability.
ARGUMENTS
Establishes the serviceability routing for dced's messages.
Starts dced by using the specified RPC protocol sequence
string or strings. Possible values include ncadg_ip_udp
(for a datagram protocol) and ncacn_ip_tcp (for a
connection-based protocol). A complete list of the protocol
sequences recognized can be found in dce/ep.idl.
DESCRIPTION
The DCE Host daemon is a process that provides services for the local
host, and is also the server used by remote applications to access
these host services. The DCE Host daemon services include the
following:
Endpoint Mapper
The endpoint mapper service maintains a database called the
local endpoint map which allows DCE clients to find servers,
individual services provided by servers, and objects managed
by services on the host. The endpoint mapper service maps
interfaces, object UUIDs, and protocol sequence
registrations to server ports (endpoints). Servers register
their bindings with the local endpoint mapper, and the end-
point mapper service on each host uses the local endpoint
map to locate a compatible server for clients that do not
already know the endpoint of a compatible server.
Host Data Management
The host data management service maintains local files of
host data that include (among others) the host_name,
cell_name, cell_aliases, and a post_processors file. The
post_processors file contains program names matched with
the other host data items (UUIDs). The dced runs the program
if the corresponding host data item is changed. There may
also be host-specific data files.
Server Management
The server management service maintains data that describes
the startup configuration (srvrconf) and execution state
(srvrexec) for each server. It also has the functionality
to start or stop particular servers, and enable or disable
specific services of servers.
Security Validation
The security validation service acts as the client side of
the security server by assuring applications that the DCE
Security daemon (secd) that the host is using is legitimate.
In addition, this service logs into the local machine when
dced is invoked and automatically updates the local machine
principal's keys.
Key Table Management
The key table management service allows for remote
maintenance of server's key tables (keytab files).
The DCE Host daemon must be running before any other DCE-based servers
are started. Each DCE host must run only a single dced, and it must run
with privileges since it typically listens on privileged or reserved
network ports. Typically, dced starts each time a host boots. (A file
called SYS$MANAGER:DCE$RPC_STARTUP.COM is responsible for configuration
issues such as deleting the endpoint map database and starting dced.)
By default, the DCE Host daemon listens on one well-known port for each
RPC protocol sequence (that is, each combination of an RPC protocol and
a transport protocol) supported by the host on which it is running. A
prot_seq argument lets you limit the protocol sequences on which dced
listens.
