Could not connect to any of the specified hosts (Linux)

[Sogl]

Hi!

This issue related to https://github.com/onlinecity/php-smpp/issues/48

I tried on some Linux machines to send sms and get an error:

Fatal error: Uncaught exception 'SocketTransportException' with message 'Could not connect to any of the specified hosts' in /var/www/public/vendor/php-smpp/php-smpp/sockettransport.class.php:262 Stack trace: #0 /var/www/public/sender.php(41): SocketTransport->open() #1 {main} thrown in /var/www/public/vendor/php-smpp/php-smpp/sockettransport.class.php on line 262

Same error on each different machines... i didn't think it is because of the firewall. Telnet works well.

This script works on the first try: https://github.com/rayed/smpp_php

I am also getting this error. Please help!

My logs (with ip addresses removed)...

Hi @MikeG-LSG, Could you please ensure the server and its port are reachable?

On Linux you can run nc -zv <host/ip> <port> or use telnet telnet <host> <port>.

You should get something like that: Connection to <host> <port> port [tcp/cslistener] succeeded!

Example: $ nc -zv google.com 80 Connection to google.com 80 port [tcp/http] succeeded!

Also make sure you do not have low timeout values. If you use other than 0, try to increase it - e.g. to 30s as follows: $transport->setRecvTimeout(30000); $transport->setSendTimeout(30000);

I am also getting same error.

Fatal error: Uncaught exception 'SocketTransportException' with message 'Could not connect to any of the specified hosts'

When I telnet the server it is getting connected. But when I checked socket_connect() response, it is throwing error(115) - operation now in progress. Any suggestions on this?

As Sogl mentioned, when I try connecting with this script it is working fine.

[Akshath0392]

I was able to resolve this issue and it was happening because of 'timeout' value. After changing to 10 sec it is working fine now.

@Akshath0392 Cool! Can you do a PR?

[Akshath0392]

@Sogl I have not modified any thing, just used setSendTimeout() API to reset the default value from 100 to 10000.

Refer sockettransport.class.php

$transport = new SocketTransport(array($host),$port); $transport->setSendTimeout(10000); $smpp = new SmppClient($transport);

// Activate binary hex-output of server interaction $smpp->debug = true; $transport->debug = true;

// Open the connection $transport->open();

[Sogl]

@Akshath0392 Just tested. Error: Fatal error: Uncaught exception 'RuntimeException' with message 'Could not read PDU body' in C:\OpenServer\domains\sms\vendor\php-smpp\php-smpp\smppclient.class.php on line 711 :confounded:

I have html from and this php code:

$server=$_POST['server'];
$port=$_POST['port'];
$username=$_POST['username'];
$password=$_POST['password'];
$phone=$_POST['phone'];
$header=$_POST['header'];
$message=$_POST['message'];

// Construct transport and client
$transport = new SocketTransport(array($server), $port);
$transport->setRecvTimeout(10000);
$transport::$forceIpv4 = true;
$transport->setSendTimeout(10000);

$smpp = new SmppClient($transport);

// Activate binary hex-output of server interaction
$smpp->debug = true;
$transport->debug = true;

// Open the connection
$transport->open();
$smpp->bindTransmitter($username, $password);

// Prepare message
$encodedMessage = GsmEncoder::utf8_to_gsm0338($message);
$from = new SmppAddress($header, SMPP::TON_ALPHANUMERIC, SMPP::NPI_UNKNOWN);
$to = new SmppAddress($phone, SMPP::TON_INTERNATIONAL, SMPP::NPI_E164);

// Send
$smpp->sendSMS($from, $to, $encodedMessage);

// Close connection
$smpp->close();

Do you have the same lines? Can you provide the last part of your code?

Another error on Linux: Fatal error: Uncaught exception 'SmppException' with message 'Error in the optional part of the PDU Body.' in /var/www/html/sms/vendor/php-smpp/php-smpp/smppclient.class.php on line 622

@Sogl Here you go!

$transport = new SocketTransport(array($host),$port); $transport->setSendTimeout(10000); $smpp = new SmppClient($transport);

// Activate binary hex-output of server interaction $smpp->debug = true; $transport->debug = true;

// Open the connection $transport->open(); $smpp->bindTransmitter($system_id,$password);

// Prepare message $message = 'Hello world'; $encodedMessage = GsmEncoder::utf8_to_gsm0338($message); $from = new SmppAddress('SMPP Test',SMPP::TON_ALPHANUMERIC); $to = new SmppAddress($phoneNumber,SMPP::TON_INTERNATIONAL,SMPP::NPI_E164);

// Send $message_id = $smpp->sendSMS($from,$to,$encodedMessage,$tags); $status = $smpp->queryStatus($message_id, $from); // Close connection $smpp->close();

I have solve the problem by setting $transport->setSendTimeout(30000);

This script works on the first try: https://github.com/rayed/smpp_php

This script works in Trans-Received mode. I think it carries MsgId in the body of the data collected from server after sending PDU. can you please tell me how to read the body after unpack?
