Using Cron with Scheduled Reports
The actual scheduling is done using the cron application. This utility executes scripts at
specific times. It is configured through a file called
crontab
. To edit the file, use the
command crontab -e . This command invokes the
vi
editor and opens the crontab table.
Entries in the table consist of a command set and a schedule. The command to run the
report is the same as described above.
The timing of the job is determined by a string of numbers preceding the script. There are
five places and they represent, in order:
•
Minute (0-59)
•
Hour (0-23)
• Day of Month (1-31)
• Month (1-12)
•
Day of Week (0-6) (Sunday = 0)
Use an asterisk(*) to mark a place that is not part of the given schedule. For example,
to run a script every Tuesday night at 11:05 PM, use "5 23 * * 2 Script".
In this example, perform the following steps to generate a predefined report and FTP it
to a server every Monday at 12:01 in the morning:
1.
Change to the utility directory by typing cd /usr/netscreen/GuiSvr/utils
2.
Create a shell script called reportscript.sh :
a.
Set the NSMUSER environment variable with an NSM domain/user pair, for
example:
export NSMUSER= domain/user
b.
Set the NSMPASSWD environment variable with an NSM password. The command
for setting environment variables depends on your operating system and shell, for
example:
export NSMPASSWD= password
c.
Specify a guiSvrCli command string
/usr/netscreen/GuiSvr/utils/guiSvrCli.sh --generate-reports --report
global:system:"\"Top Screen Attacks\” " --script ftp.sh
3.
Make the script executable. Make sure the person who creates the cron job can run
the script.
4.
Run the crontab editor:
crontab -e
5.
Add the following line:
0 0 * * 1 /usr/netscreen/GuiSvr/utils/reportscript.sh
