exec driving me nuts

[Discord]

Hey guys, i have written a wake on lan script using ether-wake that i'm trying to call from php and i just can't seem to get it to work.

I've tried putting the actual execute code in a bash script and passing args like

exec ("/pathto/./wakup.sh " . $mac);

and i've tried calling it dirrectly

exec ("/usr/bin/wolcmd " . $mac);

I've double checked permissions and they are fine. I've double checked the scripts (bash) and it works just fine. I've tried using system() and shell_execute() and virtual() all with no luck. Safe mode is off and all the exec commands are not restricted. Has anybody seen this before?

ok i found the problem, the command i'm attempt to call must be run as root. is there anyway to su apache?

Been a while since I was on a linux box, but this might work (not totally sure though):

exec("su root password"); 

Can't remember if the password can go on the same line... if it works in a *nix shell should work here. Since you're calling it from within Apache you'd effectively be su'ing the user Apache uses.

Come to think of it though... that might be opening up a huge security hole. Something to think about...

sudo might be helpful too...
