again my script!

leyearn — Tue, 16 Sep 2003 04:01:50 GMT

in order to check whether rpcd daemon is running on my system
(os hpux 10.10)

i write a script ,if it doesn't exist in my system ,start the rpcd daemon!
my script:

#!/usr/bin/sh

RPCD=$(ps -ef|grep -v grep|grep -c rpcd)
if [ $RPCD -eq 0 ]
then
/opt/dce/sbin/rpcd >>/script/rpcd/error.log2>&1
date >>/script/rpcd/date
fi

my cron is set (ervery five minute to check):

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /script/rpcd/shell >>/script/rpcd/error.log 2>&1

i can execute the script manually,but cron can't
why?

Hi,

Firstly, you have two processes writing to the same file. This won't stop it working but looks a bit odd. Either re-direct the output to error.log in the script or in the crontab file but it probably isn't wise to do it in both.

Secondly, ensure there is a space before the 2>&1 within the script. There might actually be one already but it doesn't look like it in a web browser.

It's not the normal way to start rpcd but it is perfectly valid so I wouldn't worry too much about that.

Does your error.log provide any clue as to why cron is failing. It looks OK from here.

Hi

Yes, you are starting rpcd correctly.
There should be a script called /sbin/init.d/Rpcd that starts it at boot time which you could use.

I'd guess your cron problem might be that it doesn't know the path to grep. If grep doesn't reside in /usr/bin, then you need the full path name.

Cheers
Con

but the date command can work ok!
i change the "opt/dce/sbin/rpcd >>/script/rpcd/error.log2>&1 "
to

"opt/dce/sbin/rpcd >>/script/rpcd/error.log 2>&1 "
but the problem still exist!

I have just noticed you are running 10.10 which explains why you don't have /sbin/init.d/Rpcd. I am not sure what shell /usr/bin/sh is on 10.10, is it still the posix shell? I sort of remember that early 10.X versions of HP-UX had a really buggy shell.

In cases like this, simplify!

try the following

ps -ef | grep -v grep | grep rpcd > /dev/null || {
/opt/dce/sbin/rpcd
}

See if it works

i have viewed the /var/adm/cron/log file
the following is an entry :

CMD: /script/rpcd/shell >>/script/rpcd/error.log 2>&1
> root 8847 c Tue Sep 16 14:25:00 EAT 2003
< root 8847 c Tue Sep 16 14:25:00 EAT 2003

i prove that the cron well!

Hi again,

there should be an error message in
/script/rpcd/error.log
saying what's wrong. Is that file empty?

Is the crontab for the same user as the command line user?

Check also /var/adm/cron/log for error messages.

regards,
John K.

leyearn,

Please let us know the contents of /script/rpcd/error.log it will show any errors that cron is giving.

Re: again my script!

leyearn — Tue, 16 Sep 2003 06:42:28 GMT

i have checked the file /script/rpcd/error.log
but the file is empty!

Re: again my script!

Mark Grant — Tue, 16 Sep 2003 06:52:42 GMT

Have you tried this. Make your script /script/rpcd/shell

#!/usr/bin/sh
ps -ef | grep -v grep | grep rpcd > /dev/null || {
/opt/dce/sbin/rpcd
}

With a cron entry of 0,5,10,15,20,25,30,35,40,45,50,55 * * * * /script/rpcd/shell >> /script/rpcd/error.log 2>&1

Hi again,

when you run the script manually, what happens?
Do you get any kind of messages?
The reason I ask is because that I think rpcd checks if it is already running, and if that is the case it will not start up another process. That could explain why apparently nothing happens in cron.

John K.

to john korterman
i ever killed rpcd daemon manually!
but the script didn't start the rpcd!
i have test the
if [ $RPCD -eq 0 ]
was executed!

Re: again my script!

john korterman — Tue, 16 Sep 2003 07:44:51 GMT

Hi again,

could you try to modify your script to this:

#!/usr/bin/sh
echo before first command
RPCD=$(ps -ef|grep -v grep|grep -c rpcd)
echo $?
echo after first command
if [ $RPCD -eq 0 ]
then
echo true
/opt/dce/sbin/rpcd >>/script/rpcd/error.log2>&1
echo $?
date >>/script/rpcd/date
fi
echo ended

and then run it on the command line and from cron? Please post the output from both.

regards,
John K.

leyearn,

Running out of ideas here but try running your script from cron but reading the users .profile as in

su - user -c "/script/rpcd/shell"

Re: again my script!

Zigor Buruaga — Tue, 16 Sep 2003 08:37:17 GMT

Hi,

Try to create other script that calls to "shell" script, and put it on cron.
What happens?

Kind regards,
Zigor

my cron works well

my cron is set (ervery five minute to check):

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /script/rpcd/shell >>/script/rpcd/error.log 2>&1

/var/adm/cron/log:

Hello again leyearn :)

Cron is actually starting the job but the job it is running.

That's why I want you to try doing the "su user - c" thing I mention in my last post.

It will have the same environment as when you run your script from the command line.

Also, check roots mail for output from cron.

leyearn — Wed, 17 Sep 2003 07:59:36 GMT

to Mark Grant
thanks to you and all other !

i set up the cron as root too !
as you said
should i change the root's .profile file
and add an entry
su - root -c "/script/rpcd/shell" ?
