This seems to be a problem with the ping utility that comes with FreeBSD.

This ping requires a different set of arguments. The -w option is replaced by a -t one for defining a "timeout" to wait.

As for the permissions, FreeBSD seems to prohibit a custom packet size from normal users. A quick fix would be to replace this line:

$cmd = $this->ping_path." $q -c $counts -s $packet_size -w $maxwait $host";

With this one in the package:

$cmd = $this->ping_path." $q -c $counts -t $maxwait $host";

Note that this will work only while using FreeBSD!

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

The correct OS detection is now present in the CVS version.
