Can you run 'arp' and get what you want from command line?

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:

If fixing up selinux doesn't work then look in to using 'sudo'. The
manpage(s) show examples about how to set it up to allow specific
commands to be run without a password.
Thanks for everybody's help. I have narrowed the problem down to
SELinux. Once I disabled SELinux the arp command works fine. I'm now
in the process of making it where SELinux can remain on while allowing
PHP to execute the command. Thanks a lot.

Something with the proc_* functions as you need bi-directional streams

example 1926)
?php
$root_pwd=123456;
$descriptorspec = array(
0 = array(pipe, r), // stdin is a pipe that the child will read from
1 = array(pipe, w), // stdout is a pipe that the child will write to
2 = array(file, /tmp/error-output.txt, a) // stderr is a
file to write to
);
$process = proc_open('su - -c arp', $descriptorspec, $pipes);
if (is_resource($process)) {
fwrite($pipes[0], $root_pwd.\r\n);
fclose($pipes[0]);
echo stream_get_contents($pipes[1]);
fclose($pipes[1]);
proc_close($process);
}
?
If not, you can't do that.
And with a shell-script outputting the MAC to a .txt temp file, reading
it from the PHP script?
#!/bin/bash
if [ ! $# -eq 1 ]; then
echo Usage: $0 target_ip;
exit;
fi;
MAC_ADDR=`sudo arp | grep $1 | cut -d -f18`
echo ${MAC_ADDR} /your/html/pub/dir/mac_temp.txt
Where's the root password? I guess you need it too when using sudo?
?php
$mac=file(mac_temp.txt);
foreach($mac_addr as $mac){
echo $mac_addr;
}
?
Uhm, this is really weird code, i guess you meant this:
?php
$mac=file(mac_temp.txt);
foreach($mac as $mac_addr){
echo $mac_addr;
}
?
But well, when you have root access to the server, it might be better
to just cheat like i did, and make arp available to the PHP user :)

Re: [PHP] Find MAC Address in PHP
Hi. Sorry for my bad english. :( Maybe you could write a simple deamon program in C or even in PHP to be run as root. The function of this deamon program is to listen to a port (eg. 1) and you could fsockopen it and send the IP address of the client computer and the deamon returns the MAC address of that computer. I used this kind a scheme for another problem so I guess this works. 2007. április 20. 22.00 dátummal Nathaniel Hall ezt írta: Hi all, I am attempting to find the MAC address of systems visiting my page from the local LAN.

The avc: message means its SELinux, as you suspected. You need to
temporary disable the firewall by setting it to permissive, then use
audit2allow to find out what the settings need to be to set up the
permissions properly. Look up audit2allow in the man page - they
describe the process in there.

Re: [PHP] Find MAC Address in PHP
I'm sorry, I missed that, you are right, unless there are subnets within the company, several offices in distant locations.

[PHP] Find MAC Address in PHP

Re: [PHP] Find MAC Address in PHP
Usually arp on Linux requires the user to be logged in as root. If you
can run it, try this:
?
ob_start();
passthru('arp '.$ip_addr);
$MAC = ob_get_contents();
ob_end_clean();
?
