Is this in the apache log ? This is usually an PHP error message. Still, you haven't shown your scripts, what DNS functions are implemented ? gethostbyaddr, gethostbyname , ENV{HOSTNAME} ?
Yes, I get that in apache error_log file, but I realised that it is not connected to this error. I have a small script that I just made:
The error that I get in the browser is this:
On another server it works perfectly - the diference is that the apache version is 1.3, not 2.0.

Hello everyone,
I have written a one liner which looks in a configuration file for remote hosts to connect to. It then resolves them by first ping, and nslookup if it fails, then places the info in the hosts file.
The whole thing works, seemingly, apart from one slight issue. I would like to... (0 Replies)

fsockopen
FSOCKOPEN(3) 1 FSOCKOPEN(3)fsockopen - Open Internet or Unix domain socket connectionSYNOPSIS
resource fsockopen (string $hostname, [int $port = -1], [int &$errno], [string &$errstr], [float $timeout =
ini_get("default_socket_timeout")])
DESCRIPTION
Initiates a socket connection to the resource specified by $hostname.
PHP supports targets in the Internet and Unix domains as described in "List of Supported Socket Transports". A list of supported trans-
ports can also be retrieved using stream_get_transports(3).
The socket will by default be opened in blocking mode. You can switch it to non-blocking mode by using stream_set_blocking(3).
The function stream_socket_client(3) is similar but provides a richer set of options, including non-blocking connection and the ability to
provide a stream context.
PARAMETERS
o $hostname
- If OpenSSL support is installed, you may prefix the $hostname with either ssl:// or tls:// to use an SSL or TLS client connec-
tion over TCP/IP to connect to the remote host.
o $port
- The port number. This can be omitted and skipped with -1 for transports that do not use ports, such as unix://.
o $errno
- If provided, holds the system level error number that occurred in the system-level connect() call. If the value returned in
$errno is 0 and the function returned FALSE, it is an indication that the error occurred before the connect() call. This is most
likely due to a problem initializing the socket.
o $errstr
- The error message as a string.
o $timeout
- The connection timeout, in seconds.
Note
If you need to set a timeout for reading/writing data over the socket, use stream_set_timeout(3), as the $timeout parameter
to fsockopen(3) only applies while connecting the socket.
RETURN VALUES fsockopen(3) returns a file pointer which may be used together with the other file functions (such as fgets(3), fgetss(3), fwrite(3),
fclose(3), and feof(3)). If the call fails, it will return FALSE
ERRORS /EXCEPTIONS
Throws E_WARNING if $hostname is not a valid domain.
EXAMPLES
Example #1
fsockopen(3) Example
<?php
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />
";
} else {
$out = "GET / HTTP/1.1
";
$out .= "Host: www.example.com
";
$out .= "Connection: Close
";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>
Example #2
Using UDP connection
The example below shows how to retrieve the day and time from the UDP service "daytime" (port 13) in your own machine.
<?php
$fp = fsockopen("udp://127.0.0.1", 13, $errno, $errstr);
if (!$fp) {
echo "ERROR: $errno - $errstr<br />
";
} else {
fwrite($fp, "
");
echo fread($fp, 26);
fclose($fp);
}
?>
NOTES
Note
Depending on the environment, the Unix domain or the optional connect timeout may not be available.
Warning
UDP sockets will sometimes appear to have opened without an error, even if the remote host is unreachable. The error will only
become apparent when you read or write data to/from the socket. The reason for this is because UDP is a "connectionless" protocol,
which means that the operating system does not try to establish a link for the socket until it actually needs to send or receive
data.
Note
When specifying a numerical IPv6 address (e.g. fe80::1), you must enclose the IP in square brackets--for example,
tcp://[fe80::1]:80.
