Bug description: Fsockopen function working incorrectly?
Description:
------------
I'm using Fedora Core 1 and PHP 4.3.8
I'm using the fsockopen function to check status of port for a windows
environment. I'm going thru the WAN to check this port which is two hops
away. For some reason I had a routing issue to the destination network. I
tried to ping the server from my windows workstation and I would get reply
from the router (as opposed to just getting a request timeout message)
saying the destination network was unavailable. Anyway, when I ran the
script that checks the server (from the fedora machine), the php script
would report the server as up, when in reality it couldn't be reached.
I'm guessing cause the router respoded with reply messages that the
fsockopen function assumes a connection is made?
Reproduce code:
---------------
$host = '192.168.1.1';
$port = '445';
$timeout = '2';
$fp = fsockopen($host, $port, $errno. $errstr, $timeout);
if ($fp)
{
print 'server_up.gif';
}else{
print 'server_down.gif';
}
Expected result:
----------------
Should show the host is not reachable and print "the device is down".
Actual result:
--------------
given the conditions mentioned above, the server should show down, but the
fsockopen says its up.
