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!!!!
