./xntpd status
Checking for network time protocol daemon (NTPD): running

but crontab is not working..

i ran ntpdate command by root

i m running suse 9 enterprise

thanks

run the command :

/etc/init.d/crond status

if it shows "running" then cron is running, then it shell ntpdate shall run.

But if it is not running you can start it with

/etc/init.d/crond start

to make it permanent so that it starts when the system is switched ON, you can run

insserv -a cron( or crond just not sure which one)

or

chkconfig crond on ( or crond just not sure which one)

everytime i edited the crontab i have to restart cron...n now it's working

another problem is if i run the command like
"/usr/bin/top -n 1 >> /var/x1.log" manual working

but in the crontab
"0,10,20,30,40,50 * * * * /usr/bin/top -n 1 >> /var/x1.log" it's not working

the log file from /var/log/messages " Jul 2 13:30:00 soccer /USR/SBIN/CRON[4694]: (root) CMD (/usr/bin/top -n 1 >> /var/x1.log)"

but i cant find the log in "/var/x1.log"

could u plz help me?

Hi
I'm trying to setup a cron job to automatically run . But the cron is not working properly.
When I run the command, the output file is just blank.
Here is a sample of my Crontab, any help will be much appreciated.
