Commands Reference, Volume 5
timedc Command
Purpose
Returns information about the timed daemon.
Syntax
timedc [ Subcommand [ Parameter ... ] ]
Description
The timedc command controls
the operation of the timed daemon. The timedc command does the following:
- Measures the difference between clocks on various
machines on a network.
- Finds the location of the master time server.
- Enables or disables tracing of messages received
by the timed daemon.
- Debugs.
Without any variables, the timedc command assumes an interactive mode and prompts for subcommands from
standard input. If variables are supplied, the timedc
command interprets the first variable as a subcommand and the remaining variables
as parameters to the subcommand. You can redirect standard input so the timedc command reads subcommands from a file.
Variables
The timedc command recognizes
the following subcommands:
? [ Parameter ... ] |
Displays a short description of each variable specified in the parameter
list. The ? subcommand only works in interactive mode.
If you give no variables, the ? subcommand shows a list
of subcommands recognized by the timedc command. |
clockdiff Host ... |
Computes the differences between the clock of the host machine and
the clocks of the machines given as variables. |
election Host ... |
Requests that the timed daemon on the specified
host ( s) reset its election timers and ensure that a timed master server is available. Up to 4 hosts can be specified. If a master timed server is no longer available, then the timed daemon on the specified host (s) will request to become the new timed master server.
The specified
host( s) must be running the timed daemon in submaster
mode with the -M flag. |
help [ Parameter ... ] |
Displays a short description of each subcommand specified in the
parameter list. If you give no variables, the help subcommand
shows a list of subcommands recognized by the timedc
command. |
msite |
Finds the location of the master site. |
quit |
Exits the timedc command. |
trace { on
| off } |
Enables or disables tracing of incoming messages to the timed daemon. The messages are held in the /var/adm/timed.log file. |
You can use other commands for testing and debugging
the timed daemon. Use the help
command to find these commands.
These error messages may occur with the timedc command:
Ambiguous command |
Abbreviation matches more than one command. |
Invalid command |
No match found. |
Privileged command |
Command can be executed only by the root user. |
Examples
- To display the time difference between the local
host sahara and the remote host sandy, type:
timedc clockdiff sandy
The
output would be:
time on sandy.austin.century.com is 37904247 ms ahead of time on
sahara.austin.century.com
- To display the client location of the timed daemon, type:
timedc msite
The output
would be:
client timed daemon runs on bupu.austin.century.com
