13 The updateclnt command is a client process to the updatesrv process.
14 It is used to keep the binaries and data bases on a file server in sync
15 with those on a control machine. The arguments include:
16 -d debug_level
18 This option changes the debugging level. The higher the
19 debug_level, the more information is printed. Maximum debugging
20 level is 10.
21 -h host_name
24 This is the hostname of the control machine with which this
25 process keeps up-to-date. Default: scm.
26 -q service_name
29 This is the name in /etc/services that should be used as the
30 connect portal on the machine specified by host_name above.
31 Default: rupdsrv.
32 -w wait_interval
35 The interval between probes, in seconds. The lower this number,
36 the quicker the servers will be updated when a change occurs and
37 the more cpu and network resources required. Default: 300s
38 (5min).
39 -b This option forces a .BAK file to be kept for any file that is
42 changed.
43 -r reps
46 This is the number of wait intervals between long checks. Files
47 are checked at two intervals. The interval specified by -w is
48 used for those files in /vice/db. All other files are checked
49 once each -r repetitions of length -w. Default: 6, so the long
50 interval is 30min.
51 Updateclnt checks /vice/db every wait_interval seconds. This directory
54 contains a file called files. Each file specified in it has its cur‐
55 rent date checked at the server, and a new copy of the file is fetched
56 if the date does not match that on the control machine. The format of
57 the files file is defined below.
58
60 The command updateclnt -h mahler would cause the client machine to
61 check the host "mahler" every 5 minutes to see if any of the /vice/db
62 files have changed and every 30 minutes to see if any other files have
63 changed. Normally the command is invoked by issuing the updatemon (8)
64 command with the same operands.
65
67 The format of the files file is one file name per line. A "-" as the
68 first character on the line causes the file to be deleted instead of
69 copied.
70
72 The updateclnt program can have its debug level turned on while it is
73 running by sending a kill -TSTP signal to a running updateclnt. To
74 reset the debug level back to zero, send a kill -HUP signal to the run‐
75 ning updateclnt. This also causes the UpdateLog file to not be written
76 anymore.
77
79 /vice/srv/UpdateLog
80 is the name of the log file for the updateclnt command. It can
81 be viewed by using the command tail -f /vice/file/UpdateLog. It
82 is only written if debugging has been started.
83 /vice/srv/UpdatePid
86 is the pid of the updateclnt process.
87 /vice/srv/UpdateMon
90 is the pid of the updatemon process that is keeping updateclnt
91 running.
92
95 There is no easy way to add to the list of directories checked.
96 The -r option is now obsolete as updateclnt does not update any direc‐
98 tory other then /vice/db.
