I'm having problem with using APNS with PHP on Linux server. I am using simplepush.php example script with this stream_context settings ($passphrase is set):
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert','/var/www/html/ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
stream_context_set_option($ctx, 'ssl', 'cafile', '/usr/lib/ssl/certs/Entrust_Root_Certification_Authority.pem');
and trying to connect on gateway.sandbox.push.apple.com:2195:
$fp = stream_socket_client(
'ssl://gateway.sandbox.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp){
exit("Failed to connect: $err $errstr" . PHP_EOL);
}
When I run the script it says:
PHP Warning: stream_socket_client(): Failed to enable crypto in /var/www/html/test2.php on line 27
PHP Warning: stream_socket_client(): unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Unknown error) in /var/www/html/test2.php on line 27
Failed to connect: 0
Telnet test:
Trying 17.172.232.46...
Connected to gateway.sandbox.push-apple.com.akadns.net.
Escape character is '^]'.
Server's entrust certificates:
/usr/lib/ssl/certs/Entrust.net_Global_Secure_Personal_CA.pem
/usr/lib/ssl/certs/Entrust.net_Global_Secure_Server_CA.pem
/usr/lib/ssl/certs/Entrust.net_Premium_2048_Secure_Server_CA.pem
/usr/lib/ssl/certs/Entrust.net_Secure_Personal_CA.pem
/usr/lib/ssl/certs/Entrust.net_Secure_Server_CA.pem
/usr/lib/ssl/certs/Entrust_Root_Certification_Authority.pem
777 permission are given on all certificates and also to ck.pem file which is located in the same folder as simplepush.php file (/var/www/html)
Also, I believe that ck.pem is valid certificate, because this connections success when the call is executed from Mac terminal.
SSL connection from terminal:
azureuser@myserver:/var/www/html$ openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert /var/www/html/ck.pem -CAfile /usr/lib/ssl/certs/Entrust_Root_Certification_Authority.pem
Enter pass phrase for /var/www/html/ck.pem:

Only thing that caught my eye here is this part:
routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:177:
I read that it is some sort of bug on ubuntu version, and that it can be fixed by doing ssl downgrade, but I don't really believe if that actually can be a reason.
Conclusion:
- Root certificates that apns is requesting are set
ck.pemis valid certificate (using password) and also absolute paths are set for certificates in thesimplepush.phpfiletelnetto apns is working (ports are open)- Permissions (777) are set for
ck.pem,simplepush.phpand all the root certificates openssl s_client ...is returningVerify return code: 0 (ok)and the only suspicious thing is thatssl handshake failure:s23_lib.c:177
I am missing something here (probably on my server configuration) but I ran out of ideas what it might be, and now it has become so frustrating :)
NOTE: I understand this topic could be a duplicate, but I searched a lot about all that associated with apns push, and read many topics related to this problem, and now I'm pretty sure that I have everything set and configured on server, but I'm still missing something.
Do you have any ideas what might cause this problem? Thanks in advance.
