opendir issues Wired vs Wireless

[dmcglynn@gmail.com]

Hello all..

I have a strange issue. I am trying to do an opendir via a UNC path,
from my windows server to another windows machine.

As long as my remote machine is on a physically wired connection, it
works great. However, if my remote machine is on a wireless network, I
get the following error:

Warning: opendir(\\10.51 .50.79\plc$): failed to open dir: Invalid
argument

Trying hostnames instead of using IPs doesn't seem to matter, however
simply plugging into a wired network fixes it every time..

Anyone else had a problem similar to this?

Might be a stupid question, but is the IP address of the remote machine
the same in each case?

In each case, I am setting it to the same static IP, yes.

I don't understand how PHP could possibly see a difference in the
network media.. Is there some fine-tuning on my access-point that could
fix this? It is completely confusing..

Could it just be a bad wireless connection? Did you check with eg
Netstumbler?

Well, a simple googling will give you lots of problems with network shares
and a wireless network. Most importantly: can you get to the share manually
when you're wireless? I suspect it might be more of an
firewall/access-point/ports problem...

It could be that the wireless dongle device falls asleep after a period
of non-use. Have you tried something like...

if (!($handle = @opendir($dir)) )
{
sleep 2;
if (!($handle = @opendir($dir)) )
{
sleep 3;
$handle = opendir($dir);
}
}
/* do stuff */

Re: opendir issues Wired vs Wireless

Why didn't I think to test this first, before posting to the PHP
newsgroup...

Ugh. It does not work when attempting to connect to it via
"\\192.168.1.2\ sharename" under START RUN..

So windows is refusing it for some reason, not PHP.. I apologize, and
apparently need to look elsewhere for the problem..

Thanks,
