Run this:
strace -e trace=network php yourscript.php
and paste the output here.
Also, please try running telnet from the fedora machine to that IP and
port combo to see if it does the same thing.

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.
