I was wondering if anybody knew of a command line utility that would allow me to directly write hex values to a file. such that when a hexdump of the file is done the values that I enter would be spit out. It is vital that I write directly to hex as many of the value that I need to write do not have any unicode or ascii equivalent characters associated with them. Looking for something like:

writehex f6050000 ac7e0500 02000800 01000000 newfile
hexdump newfile 
hexdump 1.02
ts.event.1
00000000: f6050000 ac7e0500 02000800 01000000 .....~..........

I am trying to grant php sudo access (for automated share mounting). I was sucess full at granting php sudo access on one of my systems by adding daemond to the list of sudo's via

su --login -c 'visudo'

so now it contains the daemond like:

daemon  ALL=(ALL)  NOPASSWD: ALL

but when I try to run a simple php script:

<?php
echo "\nfirst: ";
echo shell_exec("whoami");
echo "\nsecond: ";
echo shell_exec("sudo ls");
?>

I get the results:

first: daemon
second:

That is any time I us shell_exec with sudo in the command nothing is returned or excited. How can I grant php sudo access.

I have a fresh install of fedora 12 and am trying to get php and sqlite working I installed php through: yum install php php-devel php-pdo and restarted apache. Php pages are working just fine but whenever I try to load a page that uses sqlite the page is not processed and returns blank with non of the php code being processed. The page that i am using to test sqlite is:

 <html>
<head></head>
<body>
<?php
// set path of database file
$db = $_SERVER['DOCUMENT_ROOT']."/../library.db";

// open database file
$handle = sqlite_open($db) or die("Could not open database");

// generate query string
$query = "SELECT * FROM books";

// execute query
$result = sqlite_query($handle, $query) or die("Error in query: ".sqlite_error_string(sqlite_last_error($handle)));

// if rows exist
if (sqlite_num_rows($result) > 0) {
    // get each row as an array
    // print values
    echo "<table cellpadding=10 border=1>";
    while($row = sqlite_fetch_array($result)) {
        echo "<tr>";
        echo "<td>".$row[0]."</td>";
        echo "<td>".$row[1]."</td>";
        echo "<td>".$row[2]."</td>";
        echo "</tr>";
    }
    echo "</table>";
}

// all done
// close database file
sqlite_close($handle);
?>
</body>
</html>

The body and html tags are returned but non of the php is rendered. My question is how does one set up php with sqlite. Does one have to recompile, is their an rpm? I am looking for a step by step way of enabling sqlite for php. Thanks
