NAME
timedc —
timed control program
SYNOPSIS
timedc |
[command [argument ...]] |
DESCRIPTION
Timedc is used to control the operation of the
timed(8) program. It may be used to:
- Measure the differences between machines' clocks,
- Find the location where the master time server is running,
- Enable or disable tracing of messages received by timed, and
- Perform various debugging actions.
Without any arguments, timedc will prompt
for commands from the standard input. If arguments are supplied,
timedc interprets the first argument as a command
and the remaining arguments as parameters to the command. The standard input
may be redirected causing timedc to read commands
from a file. Commands may be abbreviated; recognized commands are:
?[command ...]help[command ...]- Print a short description of each command specified in the argument list, or, if no arguments are given, a list of the recognized commands.
clockdiffhost ...- Compute the differences between the clock of the host machine and the clocks of the machines given as arguments.
msite[host ...]- Show the master time server for specified host(s).
trace{on|off }- Enable or disable the tracing of incoming messages to timed in the file /var/log/timed.log.
electionhost- Asks the daemon on the target host to reset its "election" timers and to ensure that a time master has been elected.
quit- Exit from timedc.
Other commands may be included for use in testing and debugging timed; the help command and the program source may be consulted for details.
