Introduction to Advanced Server for UNIX Services

2.3.3 Replicator

The Replicator service allows specific files and directories to be copied automatically from the export server to one or more of the specifically configured import servers (server and clients with the Replicator service).

The Replicator service on the export server monitors the export directory, containing the designated files and directories. If a file in the export directory is changed or directories and/or files are added or deleted, the Replicator service updates these directories and files under the import directories.

2.3.4 Netlogon

The netlogon service connects a specified server to a domain. This simplifies the adminis- trator’s duties: within a domain a user account only needs to be managed and maintained on one server. User accounts can be maintained on each server using the single system image (SSI), the accounts is thus centrally managed and distributed.

The netlogon service ensures that there is an identical copy of the user account on the primary domain controller and the backup domain controllers of the domain. The netlogon service also processes the logon procedures of the clients.

If you are using the Netlogon service, the servers in a domain have several roles:

Server role	Task
Primary Domain Controller	Maintains and distributes the master copy of
	the user account database, handles “logon”
	requests.
Backup Domain Controller	Receives a copy of the user account
	database, handles “logon” requests.

The netlogon service also provides connections to other domains with which a trust relationship exists.

2.3.5 Timesource

This is a Advanced Server service which identifies a server as the time source for a domain. Other servers can synchronize their clocks with the time source.

i

UNIX servers cannot synchronise their clocks using this service.
