Wake-on-LAN combined with SUS, using KiXtart scripts

Hi,
At our office, we are using Microsoft’s SUS-server (Software Update Services), which automatically employs critical and security updates to Windows 2000 client PC’s.
The common setup of SUS often requires users to reboot their PC a few minutes after starting-up, which can be an annoyance when they are busy. Therefore I figured out how to use SUS in combination with a Wake-on-LAN function.
For this, I made two KiXtart scripts.
Both because some of you might be interested in how I did set this up, and because I (still being a novice regarding scripting) would be interested in any suggestions for improvements, I am posting these scripts in this forum.
For a complete story of how I did set this up, please take a look at the following homepage:
http://www.gironet.nl/home/evbalen/index.htm
The scripts are running under KiXtart version 4.21
This are the two scripts:
sustatus.kix
code:
;This script checks for the status of SUS Auto Update on shutdown,
;sets the WOL-trigger in a daily log file, taking into account weekends,
;and writes the AU-status to a log file.
IF @WDAYNO > 4
$Day = @YDAYNO + 8 - @WDAYNO
ELSE
$Day = @YDAYNO + 1
ENDIF
$AUState = READVALUE("HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update","AUState")
IF $AUState = 5
OPEN(1,"\\server-name\WOL$\" + @YEAR + $Day + ".log",5)
WRITELINE(1, @IPADDRESS0 + "," + @ADDRESS + @CRLF)
ENDIF
OPEN(2,"\\server-name\WOL$\sustat.log",5)
WRITELINE(2, @DATE + "," + @TIME + "," + $AUState + "," + @IPADDRESS0 + "," + @WKSTA + @CRLF)
The result of this script is a daily log file, named like "yearday.log" (for example 2003203.log).
These logs contain a list of computers that have to be started at that day.
It is in the form: "IP-address,MAC-address" on each line.
"$Day" is a variable that ensures that no startups are scheduled on Saturdays or Sundays.
"WOL$" is a share on the server where the logs are stored. Note that, because the local system account runs the script at shutdown, this share has to be read/write accessible to "Everyone".
"sustat.log" is an optional additional log file to log the status of every computer at every shutdown.
wol.kix
code:
;This script reads the daily log file for today,
;starts the respective PC's, and logs this action.
OPEN(1,"\\server-name\WOL$\suswol.log",5)
IF OPEN(2,"\\server-name\WOL$\" + @YEAR + @YDAYNO + ".log",2) = 0
$PC = READLINE(2)
WHILE @ERROR = 0
$MAC = RIGHT($PC,12)
$IP = VAL(LEFT(RIGHT($PC,16),3))
RUN "poweroff.exe wol -ip 192.168.0.$IP -subnet 255.255.255.0 -mac $MAC"
WRITELINE(1, @DATE + "," + @TIME + "," + $PC + @CRLF)
SLEEP 1
$PC = READLINE(2)
LOOP
ENDIF
The result of this script is, that all computers that are listed in the daily log file for today, are sent a magic packet by PowerOff, to initiate a Wake-on-LAN.
"suswol.log" is an optional additional log file to log all Wake-on-LAN instances.
"$PC" is a variable containing a line from the daily log file.
"$MAC" is a variable containing the computer’s MAC-address.
"$IP" is a variable containing the last octet of the computer’s IP-address.
The SLEEP function ensures that not all computers are started at the same moment, to preclude a sudden peak in power consumption.
Any thoughts about this?
Thanks,
Ed

Do A search on this board for Remote Execution Manager

Thank you Radimus and sealeopard.
Both Remote Execution Manager and KiXtart Systems Management Server are very impressive applications of KiXtart. I had no idea that this would be possible!
But, going back to my own scripts, do you consider this to be a good way to solve this particular problem? It does work, but maybe I forgot something, and it can be improved?
Thanks,
Ed

well...
to make it simpler, you don't need a daily log. Just a current one.
do a simple writeprofilestring($logfile,$austate,$ip,$mac) into a single file... the user will have that updated everytime they log in and unless you are very short of IP addresses the ip/mac addresses will never change anyway
the WOL script could be modified in the same way, to use
for each $comp in split(readprofilestring($logfile,'5',''),chr(10)) (or something similar, whatever the exact syntax is)

Thanks again Radimus.
I think I understand the concept behind your suggestion.
The sustatus-script will maintain one central ini file in which the SUS-status of every PC is logged at shutdown.
The wol-script will read this ini file every morning, and will wake all PC’s with a status of “5”.
Yes, I can see that this will be a simplification, getting rid of the date dependency.
Working with ini files is new for me. I am going to look into this later this weekend.

OK, I think I have a working version using WRITEPROFILESTRING and READPROFILESTRING.
Thanks again Radimus, for pointing me to this.
See the two new versions of the scripts below:
sustatus.kix
code:
;2003-08-17, sustatus.kix version 2.0, created by Ed van Balen.
;This script checks for the status of SUS AutoUpdate on shutdown,
;writes the AU-status to a cumulative log file,
;and sets the WOL-trigger in an initialization file if the AU-status = ”5” (Install pending).
$AUState = READVALUE('HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update','AUState')
OPEN(1,'\\server-name\WOL$\sustat.log',5)
WRITELINE(1,@DATE+','+@TIME+','+$AUState+','+@WKSTA+@CRLF)
CLOSE(1)
IF $AUState <> 5
$AUState = ''
ENDIF
WRITEPROFILESTRING('\\server-name\WOL$\suswol.ini','SUSWOL',JOIN(SPLIT(@IPADDRESS0,' '),'')+@ADDRESS,$AUState)
wol.kix
code:
;2003-08-17, wol.kix version 2.0, created by Ed van Balen.
;This script reads the WOL-trigger ini file, starts the applicable PC's,
;and writes this action to a cumulative log file.
OPEN(1,'\\server-name\WOL$\suswol.log',5)
FOR EACH $PC IN SPLIT(READPROFILESTRING('\\server-name\WOL$\suswol.ini','SUSWOL',''),CHR(10))
$IP = LEFT($PC,LEN($PC)-12)
$MAC = RIGHT($PC,12)
IF $MAC > 0
RUN 'poweroff.exe wol -ip $IP -subnet 255.255.255.0 -mac $MAC'
WRITELINE(1,@DATE+','+@TIME+','+$MAC+','+$IP+@CRLF)
SLEEP 1
ENDIF
NEXT
More background info can temporarily be found here: SUSWOL version 2 .
I had to fiddle a little with the WRITEPROFILESTRING parameters to get it working.
The IF / ENDIF sequence in the wol.kix script appeared to be necessary because the last output from SPLIT(READPROFILESTRING) is always an empty line, and PowerOff cannot handle that.
