Hello;
I have a problem that I have put considerable time into, but I keep
coming up empty. short form is that the script works from the command
line, but doesn't work from a php script. (I've already stumped the php
list.)
details follow.
I have a shell script , 'copy' consisting of 4 lines
echo * | sudo -u admn -S rm /path/to/file1
echo * | sudo -u admn -S cp /some/path/to/source1 /path/to/file1
echo * | sudo -u admn -S rm /path/to/file2
echo * | sudo -u admn -S cp /some/path/to/source2 /path/to/file2
copy is owned by www:www and is mode 777
file1 and file2 are owned by admn:www and are mode 666
copy, file1 and file2 are in the same directory which is owned by
www:www and is mode 777
I have enabled targetpw in the sudoers file as www doesn't really have
a password.
I also have a php script
<?php
echo exec ('whoami');
exec ('/path/to/copy');
?>
(just for the sake of completeness, exec passes a command to the OS and
echo prints what ever is passed to it.)
my output is "www" which is the expected result of the whoami for the
php/apache user. however no file changes happen.
however, from root:
sudo -u www /path/to/copy
changes the files exactly as expected/desired.
any suggestions/pointers/links would be appreciated.
