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:

Apr 24 09:33:51 STUAUTH kernel: audit(1177425231.020:114): avc:  denied
{ execute } for  pid=31786 comm="httpd" name="bash" dev=dm-0 ino=916642
scontext=root:system_r:httpd_t:s0
tcontext=system_u:object_r:shell_exec_t:s0 tclass=file


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.

I hope you never make your server public then or try to become a

It's my development server :)

It's LAN  only, that's why i don't need security...

I AM a server administrator, and yes, i do care about security there ;)

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

2007-04-24 Thread Puskás Zsolt ( Errotan )
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.

If not, you can't do that.

I dunno what 'arp' is gonna give you, but I wouldn't think you'd in
general have access to the MAC address of a visitor hardware...  Nor
should you, actually...  But if you've got your boxes configured to
let any ol' person run this 'arp' thing and reply with their MAC
addresses, I guess it oughta work...

  
Thanks for the help.  I believe I have narrowed it down to SELinux 
keeping Apache from executing commands.  Anybody had the same problem 
and know a fix?

Yes... You store your root pwd in your script then:



$ su - -c arp
Password:

How you'll type your root pwd? =P


Something with the proc_* functions as you need bi-directional streams
(input/output). Something like this: (not tested, partly copied form
example 1926)
 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.
> >

#!/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?






Uhm, this is really weird code, i guess you meant this:



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 :)

Ok, maybe it's because i've builded my own Linux, and didn't wanted to
have any security, but /sbin/arp has chmod value 755 on my system, and
so, i can execute it with any user.

Use exec and the extra args to get error codes.

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

Can you 'su' to PHP user and *then* run it and get what you want?

If not, you can't do that.

I dunno what 'arp' is gonna give you, but I wouldn't think you'd in
general have access to the MAC address of a visitor hardware...  Nor
should you, actually...  But if you've got your boxes configured to
let any ol' person run this 'arp' thing and reply with their MAC
addresses, I guess it oughta work...

I'm sorry, I missed that, you are right, unless there are subnets within the

The OP said he wants MACs for the machines on his local LAN. In that
case I don't think he would have meet the things you said.

Hi all,

I am attempting to find the MAC address of systems visiting my page from 
the local LAN.  I have tried several things, but it appears it will not 
let me run system commands.  For example, running 192.168.200.254"); echo $MAC; ?>" 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.


This is on a Fedora Core 6 box running PHP 5.1.6-3.4 and Apache 2.2.3-5. 
Any help is appreciated.
