Insufficient privileges to write crontab. #4

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
Whenever I try and save a simple 2 line  curl command I get

Insufficient privileges to write crontab.
If I log in as root user I CAN save 
However, the script doesn't execute by itself!
Neither does the sample Happy New Year script
* * * * * echo "Happy New Year'

Rightclick 'Run Now' and both work fine...

This is my command
//CODE start
set FILENAME = `date +"%y%m%d-%H%M%S"`
curl -o webcam/$FILENAME.jpg http://www.foo.com/webcam.jpg
//CODE end
Can someone help?

IS the problem an issue with simple having a command on more than one line??? 
If so, how to write the above on 
one line?

You'll definitely have to keep the command on a single line. If you need a 
structured script (like you seem to do) 
it's best to put it in a file and call that script from a cron command. If your 
command is not too long you can also 
concatenate the parts with ";" (execute parts regardless of success) or "&&" 
(only keep going if the previous part 
was successful).

Hope that helps,
Sven

Thanks Sven
I can save now and it works when I click 'Run Now'
However, it doesn't seem to run 'by itself'.
If I want my command to run every other minute then isn't the correct setting

??

That is correct (provided the 'Minute' column is the first one). You might want 
to confirm if cron is working in 
principle by setting a simpler schedule (like an explicit time) and see if that 
works. Also, check in Terminal if 
your cron daemon is running:

[eris:~] sas% ps aux | grep cron
root      4472   0.0  0.0    76480    652   ??  Ss    3:30PM   0:00.01 
/usr/sbin/cron
sas       4523   0.0  0.0    75492    420 s005  R+    3:31PM   0:00.00 grep cron

You must have the line beginning with 'root' or else no jobs will be executed.

Yes crontab is installed, but I'm wondering if the SETUID bit set is incorrect.
My permissions are -r-sr-sr-x. How to change so they are correct?

Not sure which file you were looking at but either way, +s looks off. I've got:

[eris:~] sas% ls -l /usr/sbin/cron 
-r-xr-xr-x 1 root wheel 90800 May 31  2008 /usr/sbin/cron
[eris:~] sas% sudo ls -l /var/at/tabs/
total 4
-rw------- 1 root wheel 236 Jun 26 16:18 sas

ok very close

used  chmod -R +rw /usr/bin/crontab
and get
-rwsr-sr-x 
but think should be
-rwsr-xr-x

Ah, you're looking at *crontab*, that is:

[eris:~] sas% ls -l /usr/bin/crontab
-r-sr-xr-x 1 root wheel 73648 May 31  2008 /usr/bin/crontab

as you say (minus 'w').
