Did you do that after [cmd=]su www[/cmd] or after [cmd=]su - www[/cmd]? See if that sudo command still works after running [cmd=]su - www[/cmd]. If not, the path to sudo is not in www's $PATH, so you'll either have to add that path or use the full path in your PHP code.
That's what I thought: the user www has no home directory, so there's no 'base' to run shell commands from. The difference between 'su' and 'su -' is that the former keeps the original environment (root's in this case), whereas the latter tries to switch to the new user's environment (which is incomplete).
If that doesn't work, try giving the www user a home directory.
And stop using colour in your posts, it's annoying.
DutchDaemon .. I do not know how can i thank you, you solved my problem perfectly.
Yes what you said is true. The code you gave me solved the problem. a lot of thanks. But i remember that i executed such command before with different way as i saw in some sites but i lost them currntly! Also thanks for all members here they helped me.
Make absolutely sure that that piece of php code is not available to an unauthorised user at any time! This is a bit like giving a lighter to a toddler in a room full of nylon curtains. Drenched in petrol. With an open tank of oxygen.
So here on the FreeBSD forum, if you politely make a remark that a moderator was a little rude, apparently your posts get deleted. So Moderators can be as rude as they want, and if someone speaks out in defense, they are deleted....
I'm not trying to start anything, but this kind of practice is unnerving.
Don't post here if you don't like it, RusTus. I told you in private, I will tell you here for the last time. Rudeness is in the eye of the beholder (I found your replies in this thread more rude than I would ever be), and apparently the affected poster was less affected by it than yourself. This probably says more about you than about me, or said poster. Closed.
