17.1 What is DHost?
Novell
®
eDirectory software for Windows, Solaris, Linux, AIX, and HP-UX is built upon the same
core code as eDirectory for NetWare
®
. In order for eDirectory for Windows, Linux, and UNIX to
properly interact with the other versions of eDirectory, they support a subset of NetWare Core
Protocol
TM
(NCP
TM
) services. This is handled by a program called DHost. DHost sits beneath
eDirectory and provides functionality on non-NetWare platforms that the NetWare operating system
provides naturally.
DHost provides the following NetWare oriented services:

Service Description
NCP Engine A packet-based protocol that enables a client to send requests to and receive
replies from a NetWare server.
For more information, see NetWare Core Protocols (http://developer.novell.com/
ndk/doc/ncp/ncp__enu/data/hc4lztgy.html) .
Watchdog Packets used to make sure workstations are still connected to the NetWare
server.
For more information, see Watchdog Packet Spoofing (http://www.novell.com/
documentation/lg/nw65/ipx_enu/data/h0cufuir.html) .
Connection Table A unique number assigned to any process, print server, application, workstation,
or other entity that attaches to a NetWare server. The number can be different
each time an attachment is made. Connection numbers are used in
implementing network security and for network accounting. They reflect the
objects place in the file servers connection table. Additionally, they provide an
easy way to identify and obtain information about the objects logged in on the
network.
Event System Provides a way for applications to monitor the activity of an individual server.
Thread Pool A sequence of instructions executed as an independent entity and scheduled by
system software.
NCP Extensions Allows server application developers to write NLM TM software to be implemented
in the NetWare OS as NCPs.
For more information, see NCP Extension Concepts (http://
developer.novell.com/ndk/doc/ncp/index.html?page=/ndk/doc/ncp/ncp__enu/

.
Message Digest A compressed or condensed form of a document, or an abstract from a
document, that functions as a “digital fingerprint” of the larger document. A
message digest is used to create a digital signature that is unique to a particular
document.
