Re: How can I have PHP set the linux system date/time?

$execString = "/usr/bin/sudo /bin/date ".$binDate."<BR>";

                                                  ^^^^^

I believe the problem is here Daevid Vincent wrote:

I'm not sure what I'm doing wrong... In changetime.php:

       $binDate = date ("mdhiY",

mktime($hour,$minute,0,$month,$day,$year));

       $execString = "/usr/bin/sudo /bin/date ".$binDate."<BR>";

       //echo $execString."<BR>";
       exec($execString); 

And then in /etc/sudoers: nobody ALL=NOPASSWD: /bin/date If I run the command (as daevid) "/usr/bin/sudo /bin/date 011304042003" for example, it works fine. Apache is running as nobody it seems: [daevid=pts/6]4:10am@dev:{/www/htdocs}> ps aux | grep "httpd"

You need root priviledges, that means /bin/date must run as root. You can use sudo Daevid Vincent wrote:

Yep, I am trying to have a php web page change the linux system date/time, but obviously running into the snag that /bin/date, while "chmod 775" doesn't allow a user to set the date/time. Why is that, given the permissions? Sure it makes sense, but it's

annoying. Ideas on

how to circumvent this problem?

-rwxr-xr-x    1 root     root        26780 Jul 23  2001 /bin/date

Seems to me that anyone should be able to use it then right? Where is the "write" portion defined? The 'info date' page says, "You

must have

appropriate privileges to set the system clock." But it

doesn't say what

that is or how to change them. If anyone cares, here's a nice bit-o-code: <?php if ($year == "") $year = date("Y"); if ($month == "") $month = date("m"); if ($day == "") $day = date("d"); if ($hour == "") $hour = date("h"); if ($minute == "") $minute = date("i"); $NewDateTime = date ("m/d/Y H:i", mktime ($hour,$minute,0,$month,$day,$year)); $binDate = date ("mdhiY", mktime ($hour,$minute,0,$month,$day,$year)); exec("/bin/date ".$binDate); //TODO: um, yeah, how do you expect this to work? you have to be root to do this!!!! ?> <CENTER> <table border=0 class=componentBox> <TR><TD COLSPAN=8 class=Header>Change Time / Date</TD></TR> <TR> <FORM ACTION="<?=$SCRIPT_NAME?>" METHOD="POST"> <TD> <TABLE BORDER=0> <TR><TD class=Menu>New Date</TD><TD> <select name="month"> <?php for($i = 1; $i <= 12; $i++) { echo "<option"; if ($month == $i) echo " SELECTED"; printf(">%02d\n",$i); } ?> </select> / <select name="day"> <?php for($i = 1; $i <= 31; $i++) { echo "<option"; if ($day == $i) echo " SELECTED"; printf(">%02d\n",$i); } ?> </select> / <select name="year"> <option <?php if ($year == "2003") echo " SELECTED"; ?>>2003 <option <?php if ($year == "2004") echo " SELECTED"; ?>>2004 <option <?php if ($year == "2005") echo " SELECTED"; ?>>2005 <option <?php if ($year == "2006") echo " SELECTED"; ?>>2006 </select> </TR> <TR><TD class=Menu>New Time</TD><TD> <select name="hour"> <?php for($i = 0; $i <= 23; $i++) { echo "<option"; if ($hour == $i) echo " SELECTED"; printf(">%02d\n",$i); } ?> </select> : <select name="minute"> <?php for($i = 0; $i <= 59; $i++) { echo "<option"; if ($minute == $i) echo " SELECTED"; printf(">%02d\n",$i); } ?> </select> </TR> <TR><TD COLSPAN=2 ALIGN=RIGHT> <INPUT TYPE="SUBMIT" NAME="SUBMIT" VALUE="Set Time / Date"
