Notes on Cell Administration

Diagnostic Tool — dceping

HP DCE/9000 includes an HP-developed diagnostic tool, dceping.

dceping provides information on the status of a client machine within

its cell. The following is a brief description of dceping.

dceping veriﬁes that a local client can communicate with DCE and

other services within a cell. You may specify services that you want

dceping to contact by modifying the system-wide ﬁle

/etc/opt/dce/hpadmin/nondcesvc, or the per-user ﬁle

$HOME/.nondcesvc. (See the nondcesvc (4) man page.) You may either

list the names of the services in these ﬁles or list the name of an

executable that dceping would run to determine the names of the

services to ping. In addition, you may embed, in the service name,

environment variables which are expanded with their value at the time

dceping is run. If a variable is not in the current environment, dceping

does not attempt to contact the corresponding service.

dceping may also be used to ping services on a platform different from

HP or in a different cell (in this case proper cross-cell communication

path must have been previously setup). As long as you specify the

service's name in the right format (as speciﬁed in nondcesvc (4)),

dceping will contact these services.

For additional details and command-line syntax, see the dce_which (8)

and dceping (8) man pages.
