chkconfig and linux scripts
 

I would like to one of my script in startup, I have copied into inist.d directory and try to do the followig command and it doesn't work.

# chkconfig dnstest on
service dnstest does not support chkconfig


Does dnstest file needs to be in any standard format? PLease let mek now.

assuming the file is workable, you need to

chkconfig -add dnstest

to "add" the service to chkconfig before "chkconfig dnstest on". You only need to add it once

(please check format in man page - writing from memory)

Thank you, but isn't it same command. I tried and getting same error.

# chkconfig --add dnstest
service dnstest does not support chkconfig

Am I missing anything here? Please help me.

Could you post the header of your script?

Usually the scripts in /etc/init.d are wrapper scripts that start daemons or other scripts.
Look for /etc/init.d/skeleton. If it exists, you can base such a script on it.

And chkconfig --add XXX is not the same as chkconfig XXX on. Add adds the "service" into chkconfig, On tells it what to do at startup for each runlevel

They are not the same commands. Actually your first post the command does not have the correct syntax.
See man chkconfig for more information.

The initscript header does have a certain format. The format depends on the linux distribution/version you are running. Have you looked at the files already in the /etc/init.d directory?

Onther way around the problem, especially if you just want a one-off execution, is to run the script from rc.local or you can even run it from a user's cron with @reboot
