OSF DCE Administration Guide--Core Components

Managing DCE Hosts

The following example shows conﬁguring host ptarmigan as a DCE client system.

The cell’s security server is on host eagle and the CDS server is on host owl. The

administrator’s principal name is cell_admin and the administrator’s password is

-dce-.

dcecp> host conﬁgure /.:/hosts/ptarmigan -client -secmaster eagle \

-cds owl -administrator cell_admin -password -dce-

7.7 Removing a DCE Host from a Cell

Occasionally, you might want to remove a DCE host from a cell. For instance, your

organization is replacing some older systems that are being sold to another organization.

Removing or unconﬁguring a DCE host is more than just erasing DCE information from

the host’s disk because CDS and the DCE Security Service both maintain host-speciﬁc

information that needs to be removed as well. The host unconﬁgure operation deletes

all objects, directories, and links from the /.:/hosts/hostname CDS directory including the

directory itself. It also deletes all principal names beginning with hosts/hostname/

which, in turn, removes all accounts with the same name. Finally, it removes all local

conﬁguration ﬁles and stops all running DCE processes ending with the DCE daemon

(dced).

The host unconﬁgure operation operates only on remote hosts. You cannot perform this

operation on a local host because it removes the DCE Security Service registry

information needed to complete the operation. Also note that you need cell administrator

privileges to perform a host unconﬁgure operation.

To remove a remote DCE host from a cell, use a host unconﬁgure operation providing

the host name of the host to be unconﬁgured. The following example removes host

calypso from the cell:

dcecp> host unconﬁgure /.:/hosts/calypso

You can remove multiple DCE hosts from a cell by providing a dcecp list of names of the

hosts to be unconﬁgured. The following example removes hosts calypso, hydra, and

nova from the cell:

dcecp> host unconﬁgure {/.:/hosts/calypso /.:/hosts/hydra /.:/hosts/nova}

If you have cell administrator privileges in a foreign cell, you can remove a remote DCE

host from that cell by supplying a global DCE name of the host to be unconﬁgured. The

following example removes host gobo from foreign cell /.../their_cell.goodco.com:

dcecp> host unconﬁgure /.../their_cell.goodco.com/hosts/gobo
