SYNOPSISupdateclnt [ -d debug_level ] [ -h host_name ] [ -q service_name ] [ -w
wait_interval ] [ -r reps ]
DESCRIPTION
The updateclnt command is a client process to the updatesrv process.
It is used to keep the binaries and data bases on a file server in sync
with those on a control machine. The arguments include:
-d debug_level
This option changes the debugging level. The higher the
debug_level, the more information is printed. Maximum debugging
level is 10.
-h host_name
This is the hostname of the control machine with which this
process keeps up-to-date. Default: scm.
-q service_name
This is the name in /etc/services that should be used as the
connect portal on the machine specified by host_name above.
Default: rupdsrv.
-w wait_interval
The interval between probes, in seconds. The lower this number,
the quicker the servers will be updated when a change occurs and
the more cpu and network resources required. Default: 300s
(5min).
-b This option forces a .BAK file to be kept for any file that is
changed.
-r reps
This is the number of wait intervals between long checks. Files
are checked at two intervals. The interval specified by -w is
used for those files in /vice/db. All other files are checked
once each -r repetitions of length -w. Default: 6, so the long
interval is 30min.
Updateclnt checks /vice/db every wait_interval seconds. This directory
contains a file called files. Each file specified in it has its cur‐
rent date checked at the server, and a new copy of the file is fetched
if the date does not match that on the control machine. The format of
the files file is defined below.
EXAMPLES
The command updateclnt-h mahler would cause the client machine to
check the host "mahler" every 5 minutes to see if any of the /vice/db
files have changed and every 30 minutes to see if any other files have
changed. Normally the command is invoked by issuing the updatemon (8)
command with the same operands.
FORMAT
The format of the files file is one file name per line. A "-" as the
first character on the line causes the file to be deleted instead of
copied.
DIAGNOSTICS
The updateclnt program can have its debug level turned on while it is
running by sending a kill -TSTP signal to a running updateclnt. To
reset the debug level back to zero, send a kill -HUP signal to the run‐
ning updateclnt. This also causes the UpdateLog file to not be written
anymore.
FILES
/vice/srv/UpdateLog
is the name of the log file for the updateclnt command. It can
be viewed by using the command tail -f /vice/file/UpdateLog. It
is only written if debugging has been started.
/vice/srv/UpdatePid
is the pid of the updateclnt process.
/vice/srv/UpdateMon
is the pid of the updatemon process that is keeping updateclnt
running.
BUGS
There is no easy way to add to the list of directories checked.
The -r option is now obsolete as updateclnt does not update any direc‐
tory other then /vice/db.
