Running programs...

Hello,

I have a question... of course!

I THINK my question is related to suexec...

I have a GUI on my server, written in PHP.
It has a wrapper program, written in C I think (compiled), that runs a
few commands.

Now, I recently upgraded my system to Fedora 9 and the latest apache.
Suddenly, the wrapper program refuses to work. Strange, since I
chmodded/chowned the wrapper as root:apache, 750 u+s.

When I click the button that spawns the wrapped process, I see it
being executed (when I very quickly run a 'ps auxww'). But it dies
instantly... I don't see anything in the logs...
Apache doesn't crash, so I dont really have a backtrace or anything to
work with.

Can anyone tell me how I can make it so I can debug this? Is there a
flag I can set or something?
Or does anyone perhaps have any pointers as to what to watch out for?

Thank you.
Frank.

Can you run the program from the server itself? I.e., don't use a web
browser or GUI, just go the command line and try to run the program.
It sounds like it is running, but failing (or at least failing to do
what you expect). Off hand, I'd guess this is a problem with the
program, not apache or your configuration. Perhaps the program is
trying to access some files or libraries that no longer exist since
the upgrade?

Hi Brian,

thanks for your remark:
> Can you run the program from the server itself?

I actually did test this, but forgot to mention it.
Yes, I did run it manually, and it does what it is supposed to do.
So that's not it. It really is the combo apache+running this program...

Does suexec of something trivial work? If not, what's in
the suexec log?

Does it work if you turn off selinux?

I don't really see a suexec log? Where do I find this?
In the general apache logs, I don't see anything... that's the whole
annoying part!

It is, and was, off; always. (I don't like it)

Hi,

could anyone point me to a log file or suexec or something?
The standard apache error log shows nothing about my problem. ....
