I'm trying to use a script to query if a Shoutcast Server is online or offline. The code below is what I'm using at the moment.
$vt_ip = "ip";
$vt_port = "port";
$output = #fsockopen($vt_ip, $vt_port, $errno, $errstr, 2);
if (!$output) {
echo "<FONT CLASS=f1 COLOR=#DD0000><B>OFFLINE</B></FONT>";
} else {
echo "<FONT CLASS=f1 COLOR=#00DD00><B>ONLINE</B></FONT>";
}
#fclose($output);
But it doesn't update, it is stuck on Offline status.
Any help would be greatly appreciated.
$vt_ip = "ip";
$vt_port = "port";
$conn = fsockopen($vt_ip, $vt_port, $errno, $errstr, 2);
if(!$conn){
echo $errno;
}else{
fwrite($conn, "\n");
$output = fread($conn, 1024);
fclose($conn);
if ($output == "") {
echo "<FONT CLASS=f1 COLOR=#DD0000><B>OFFLINE</B></FONT>";
} else {
echo "<FONT CLASS=f1 COLOR=#00DD00><B>ONLINE</B></FONT>";
}
}
It isn't enough to simply make a TCP connection to a SHOUTcast server to determine if the stream is working. In fact, a SHOUTcast server that is running will always accept yourTCP connection, even if there is no stream for playback.
You must connect, request the stream, and then check the return status code. Once connected, send this data:
GET /; HTTP/1.0
Follow that by a \r\n\r\n. Now, read data back from the stream until you get the \r\n\r\n. Then, you can disconnect. Check the status code from the first response line and see if it's 200. If it is, you've got an active stream.

I have a question about pinging certain game servers to see if they are alive or not, most work fine with just your standard PHP ping but others are from steam... and steam is making it more difficult for me to just send a ping to see if it is alive or not, i tried Steam Condenser but... have no idea how to use it since there is no documentation.
my question
how can i ping UDP game servers such as Arma 2, Arma 3, etc. this is what i tried:
$host = '128.0.0.1';
$port = 1234;
$waitTimeoutInSeconds = 7;
if($fp = fsockopen("udp://".$host,$port,$errCode,$errStr))
{
echo 'Online';
}
else
{
echo 'Offline';
}
the problem with that is that i always get "true" returned no matter what IP or port i use, how can i make this work?
EDIT
I also tried
$host = '128.0.0.1';
$port = 1234;
$waitTimeoutInSeconds = 7;
if($fp = fsockopen("udp://".$host,$port,$errCode,$errStr))
{
$write = fwrite($fp,"x00");
if (!$write)
{
echo 'offline';
}
else
{
echo 'online';
}
}
else
{
echo 'offline';
}
fclose($fp);
however with this one i get error code 0 which seems to be a problem with the initializing of the socket?
I tried this one, by removing the "udp://" :
$host = '128.0.0.1';
$port = 1234;
$waitTimeoutInSeconds = 7;
if($fp = fsockopen($host,$port,$errCode,$errStr))
{
echo 'Online';
}
else
{
echo 'Offline';
}
And it works. Here is the return text :
Warning: fsockopen(): unable to connect to 128.0.0.1:1234 (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ) in C:\xampp\htdocs\test.php on line 6
Offline
It don't think you should put the "udp://" because just using the port number is enough.
What about using the OS's ping utility, execute terminal ping command using PHP. You can read it here : http://php.net/manual/en/function.shell-exec.php
I'm using a [PHP Telnet Class][1] to connect to server via telnet to send commands. It connects to the server successfully but it fails to login in..
require_once "PHPTelnet.php";
$telnet = new PHPTelnet();
// if the first argument to Connect is blank,
// PHPTelnet will connect to the local host via 127.0.0.1
$result = $telnet->Connect('172.20.66.100','username','password');
if ($result == 0) {
$telnet->DoCommand('another command', $result);
echo $result;
$telnet->Disconnect();}
===============================================================================
UPDATE:
My script is working, there was some conflict going on with my virtual machine......
Try this:
$url = 'tcp://ADDRESS_HERE:PORT_HERE';
$fp = stream_socket_client($url, $errno, $errstr, 10);
if (!$fp) {
echo ("$errstr ($errno)<br />\n");
exit;
} else {
$command = 'execute_command_line' . PHP_EOL;
fwrite($fp, $out);
stream_set_blocking($fp, true);
while (!feof($fp)) {
$output = stream_get_contents($fp);
}
fclose($fp);
echo output;
}
According to the documentation in the PHPTelnet website you have the parameters to the constructor in the wrong order.
In the library's documentation there is the following example:
$result = $telnet->Connect('www.somewhere.com','login name','password');
Therefore, you should have:
$result = $telnet->Connect('172.20.66.100','username','password');
Source: PHPTelnet Documentation
EDIT
You mentioned that you get erro nº 3. In the source code, error 3 has the following description: Connect failed: Login Failed
Which points to the following URL:
Information about Error 3
Which lists the possible causes as:
You misspelled your username or password (i.e. Your credentials are wrong)
Telnet service is not available for your username and password (i.e. Your user does not have permissions to access the Telnet service)
I've been trying to connect to a Twitch chat via IRC. I've added an echo function to test where I had connected or not as that page was blank and an account didn't join the IRC.
Here is my code:
<?php
set_time_limit(0);
ini_set('display_errors', 'on');
$datatwitch= array(
'server' => 'irc.twitch.tv',
'port' => 6667,
'nick' => 'greatbritishbgbot',
'name' => 'greatbritishbgbot',
'pass' => 'oauth:HERE',
);
?>
<?php
//The server host is the IP or DNS of the IRC server.
$server_host = $datatwitch['server'];
//Server Port, this is the port that the irc server is running on. Deafult: 6667
$server_port = $datatwitch['port'];
//Server Chanel, After connecting to the IRC server this is the channel it will join.
$server_chan = "#greatbritishbg";
//login password
$nickname = $datatwitch['name'];
$nickname_pass = $datatwitch['pass'];
//Ok, We have a nickname, now lets connect.
$server = array(); //we will use an array to store all the server data.
//Open the socket connection to the IRC server
$server['SOCKET'] = #fsockopen($server_host, $server_port, $errno, $errstr, 2);
if($server['SOCKET'])
{
//Ok, we have connected to the server, now we have to send the login commands.
echo "connected";
SendCommand("PASS $nickname_pass \n\r"); //Sends the password not needed for most servers
SendCommand("NICK $nickname\n\r"); //sends the nickname
SendCommand("USER $nickname USING PHP IRC\n\r"); //sends the user must have 4 paramters
while(!feof($server['SOCKET'])) //while we are connected to the server
{
$server['READ_BUFFER'] = fgets($server['SOCKET'], 1024); //get a line of data from the server
echo "[RECIVE] ".$server['READ_BUFFER']."<br>\n\r"; //display the recived data from the server
/*
IRC Sends a "PING" command to the client which must be anwsered with a "PONG"
Or the client gets Disconnected
*/
//Now lets check to see if we have joined the server
if(strpos($server['READ_BUFFER'], "422")) //422 is the message number of the MOTD for the server (The last thing displayed after a successful connection)
{
//If we have joined the server
SendCommand("JOIN $server_chan\n\r"); //Join the chanel
}
if(substr($server['READ_BUFFER'], 0, 6) == "PING :") //If the server has sent the ping command
{
SendCommand("PONG :".substr($server['READ_BUFFER'], 6)."\n\r"); //Reply with pong
//As you can see i dont have it reply with just "PONG"
//It sends PONG and the data recived after the "PING" text on that recived line
//Reason being is some irc servers have a "No Spoof" feature that sends a key after the PING
//Command that must be replied with PONG and the same key sent.
}
flush(); //This flushes the output buffer forcing the text in the while loop to be displayed "On demand"
}
} else {
echo "connection failed";
}
function SendCommand ($cmd)
{
global $server; //Extends our $server array to this function
#fwrite($server['SOCKET'], $cmd, strlen($cmd)); //sends the command to the server
echo "[SEND] $cmd <br>"; //displays it on the screen
}
?>
It appears I can't Get passed if($server['SOCKET']). Is there anyway I can diagnose this? As I have directly connect with the details in hexChat.
The server had actually been preventing me to use fsocket. After contacting my host and moving away from a shared host it started to work.
Please take a look at this answer: https://stackoverflow.com/a/24835967/1163786
Especially:
$socket = fsockopen($bot["Host"], $bot["Port"], $error1, $error2);
if(!$socket) {
echo 'Crap! fsockopen failed. Details: ' . $error1 . ': ' . $error2;
}
To get the details about the socket error = reason for socket not connecting.
Currently, you have $errno, $errstr on fsockopen, but echo only "connection failed".
The title explains it all...
How can i connect to an IP using tcp protocol and read/get the response?
I have searched a lot but i didnt find any solution.
$socket = stream_socket_server("tcp://127.0.0.1:22", $errno, $errstr);
if (!$socket) {
echo "$errstr ($errno)<br />\n";
} else {
while ($conn = stream_socket_accept($socket)) {
echo fread($conn, 26);
fclose($conn);
}
fclose($socket);
}
is this code ok?
Does the job?
Because it seems it doesn't do the job...
Thanks in advance
As suggested by others; avoid using port 22. I recommend using an obscure (unused) socket port number > 1024 such as 4444. Anything below 1024 normally requires root access.
If you need to test connectivity for 22 have your server script run additional functions.
As for sending a response back to the connected client use stream_socket_recvfrom($socket, $length, 0, $peer) instead of fread()
Then on the client side add a response listener:
client.php
$socket = stream_socket_client('tcp://127.0.0.1:4444');
if ($socket) {
$sent = stream_socket_sendto($socket, 'message');
if ($sent > 0) {
$server_response = fread($socket, 4096);
echo $server_response;
}
} else {
echo 'Unable to connect to server';
}
stream_socket_shutdown($socket, STREAM_SHUT_RDWR);
server.php
$conn = stream_socket_server('tcp://127.0.0.1:4444');
while ($socket = stream_socket_accept($conn)) {
$pkt = stream_socket_recvfrom($socket, 1500, 0, $peer);
if (false === empty($pkt)) {
stream_socket_sendto($socket, 'Received pkt ' . $pkt, 0, $peer);
}
fclose($socket);
usleep(10000); //100ms delay
}
stream_socket_shutdown($conn, \STREAM_SHUT_RDWR);
Run server.php which will listen in an endless loop listening for a non-empty packet
once server.php receives a packet it will respond back to the connected client with the received packet.
Then execute client.php which will send 'message' to server.php
Once sent it will then retrieve and echo the response from server.php which should read 'Received pkt message'
From http://php.net/stream_socket_accept
Accept a connection on a socket previously created by stream_socket_server().
That means it waits that one client wants to connect. (You just bind yourself to the port, but don't connect anything)
And fread is also the wrong function to use with socket_* functions. Correct function would be stream_socket_recvfrom().
But this really isn't what you seem to want. You appearently want to open a connection to some place. So fsockopen() is the right function:
$conn = fsockopen("127.0.0.1", 22, $errno, $errstr);
if (!$conn) {
echo "$errstr ($errno)<br />\n";
} else {
echo fread($conn, 26);
fclose($socket);
}
I am writing a simple php socket code.
Here is my code
<?php
$address="127.0.0.1";
$port=9875;
echo "I am here";
if(false==($socket= socket_create(AF_INET,SOCK_STREAM, SOL_TCP)))
{
echo "could not create socket";
}
socket_bind($socket, $address, $port) or die ("could not bind socket");
socket_listen($socket);
if(($client=socket_accept($socket)))
echo "client is here";
?>
when I run this program my browser only shows waiting for localhost.
Is there any problem in my code?
I am using xammp 1.7.4 .
Another thing I want to know if I want to get a HTTP or FTP request do I have change only the port number?
I verified the code and tested in my system and it works correctly. Showing as "client is here" after running the client.
File Name: server.php
<?php
$address="127.0.0.1";
$port=9875;
echo "I am here";
set_time_limit (0);
if(false==($socket= socket_create(AF_INET,SOCK_STREAM, SOL_TCP)))
{
echo "could not create socket";
}
socket_bind($socket, $address, $port) or die ("could not bind socket");
socket_listen($socket);
if(($client=socket_accept($socket)))
echo "client is here";
socket_close($socket);
?>
First run the server.php file.
File: client.php
<?php
$host="127.0.0.1" ;
$port=9875;
$timeout=30;
$sk=fsockopen($host,$port,$errnum,$errstr,$timeout) ;
if (!is_resource($sk)) {
exit("connection fail: ".$errnum." ".$errstr) ;
} else {
echo "Connected";
}
?>
Now run the client.php
Your output should be like this (as I got in my system)
I am hereclient is here
If not, make sure your firewall is not blocking the request. Temporarily disable antivirus if you have one.
That is the expected behaviour of waiting.
The program you have written is a socket server which is ready to listen to the connection with the specified port, until then it will wait.
You can create a client who connects so that you will see the response "Client is here". The client can be any programming language including PHP.
Below is a sample code in PHP (I didn't verify it).
$fp = stream_socket_client("127.0.0.1:9875", $errno, $errstr);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
// Handle code here for reading/writing
}
You can check this link for sample client code in PHP.
EDIT
$host = "127.0.0.1";
$port = 9875;
$timeout = 30;
$sk = fsockopen($host, $port, $errnum, $errstr, $timeout);
if (!is_resource($sk)) {
exit("connection fail: " . $errnum . " " . $errstr);
} else {
echo "Connected";
}
