Re: PHP and cron jobs

Thanks David, I deleted all the files and changed teh ribbon creation
routine to chmod the file when it was created as 666, this looks like it has
worked!

As this is a shared host running the cron as root or sudo (new to me but
from what I can tell changes me as a used to root with passwrod) are two
options not open.

Hey all

I help out at a gaming website, where we play BF2 and track player
stats/give them awards etc. I've got a whole backend and everything works
exactly as I need... except for when I need to update the awards via cron
job. Then I'm getting a "imagepng(): Unable to open 'xxx.png' for writing
in XXX". All the paths are correct as it loads other images as part of
the process, and I belive it's a permission issue. The files are in a 777
folder and each file has the permission of 644 (User 65534, grou 65534) -
what am I doing wrong?

(BTW tried different permissions, and if I delete the file the cron job
creates it, but then you can't access it via a http request)

Many thanks


As I understand it:

cron runs as the effective user id of the name of the crontab file.
e.g. if you have a crontab file named 'foo', then crontab will run as the
effective user 'foo'.

I say 'effective user' since if there are two accounts, say 'foo' and
'bar', and both have a userid of 1234 and 'bar' is located ahead of 'foo'
in the /etc/passwd file, then cron will run as 'bar' even though the
crontab file is named 'foo'.

That aside, I think your issue is that the effective user cron is running
your job as is not able to write the file. (i.e. it is not running as user
65534).

Solutions:
1. run the cron job as user 65534.
2. run the cron job and sudo to userid 65534
3. open the permissions on xxx.png to 666
