Hi I'm Paolo from Italy.
I have a problem using readdir function (and other similar functions) under a ssh2 connection.
This is my script:

<?
$Server = "XXX.XXX.XXX.XXX";
$Porta = "XXXX";
$Login = "YYYYYYYY";
$Password = "ZZZZZZZZ";
if (!extension_loaded('ssh2'))
{exit();
}
$connection = ssh2_connect($Server, $Porta);
if (!$connection)
{exit();
}
if (!ssh2_auth_password($connection, $Login, $Password))
{exit();
}
if (!$sftp = ssh2_sftp($connection))
{exit();
}
if (is_dir("ssh2.sftp://$sftp/uploads/"))
{echo "1 Ok.\n";
$Directory = opendir("ssh2.sftp://$sftp/uploads/") or die ("");
if ($Directory)
{echo "2 Ok.\n";
while (false !== ($file = readdir($Directory)))
{echo "File -> ".$file."\n";
}
echo "3 Ok.\n";
}
}
unset($connection);
?>

(Obviously I have mask the important thinks)
If I try to use it in my VM debian server, I see this echo:

1 Ok
2 Ok
File -> TestFile1.csv
File -> TestFile2.csv
File -> TestFile3.csv
3 Ok

But if I try to use the same script in my regular server (a debian one, same version of the previous one, some php version, some ssh2 library version), I receive this echo:

1 Ok
2 Ok
3 Ok

Via tcpdump I see that SFTP server gives me exactly the same infos in both tests.
And if I try to open a file (knowing its name) with fopen/fgets in the second server, it works.

So why readdir (and functions similar) fails, while fopen/fgets works?
I watch php configurations on both server and thay seems identical.
Where do I have to search?

Thanks in advance
Best regards
Paolo

How is system security set up in the working and failing systems?
Perhaps you don't have permission to list the directory in the failing one?

It all depends on the version of Linux you're using. Try a Linux
administration book (or newsgroup) for your version.

Hi.

Can you help me, telling me which kind of permission (or its name) I have to look for in a server using debian 6.0?

Thanks in advance

Paolo

As I said - you need to be asking in a newsgroup for Linux, preferably
Debian or Ubuntu. Debian does have an excellent email list for user
assistance.

Ask in the right place and you'll get good answers.
