does not give me any
output. I have copied arp to a place that the apache user can execute
from and ensured arp is executable.
Use exec and the extra args to get error codes.
ARP is a root-command... =]
Can you run 'arp' and get what you want from command line?
As web-user? No.
Can you 'su' to PHP user and *then* run it and get what you want?
Hum... Not at all... You need to enter the root password... How can you do
that?
sudo sounds a little better... But... How about security?
I know it can be done because I have a Fedora Core 4 system doing it
right now. I didn't have to do anything special for it to work. The
system I am working on now is a Fedora Core 6 box. In /var/log/messages
I receive:
