I have a small script that basically implements DDNS for two hosts by using SOAP calls to change the A record of a given subdomain. Now, after the upgrade from 3.0.5pX to 3.1.1p1 (and Ubuntu 14.04 to 16.10), the soap call (the very first login call) gives an Internal Server Error: Code: [email protected]:~# /volume1/\@appstore/PHP5.6/usr/local/bin/php56 /volume1/temp/ispconfig-ddns/update.php aon kainhofer.com PHP Fatal error: Uncaught SoapFault exception: [HTTP] Internal Server Error in /volume1/temp/ispconfig-ddns/update.php:36 Stack trace: #0 [internal function]: SoapClient->__doRequest('<?xml version="...', 'https://server....', 'https://server....', 1, 0) #1 /volume1/temp/ispconfig-ddns/update.php(36): SoapClient->__call('login', Array) #2 /volume1/temp/ispconfig-ddns/update.php(36): SoapClient->login('REMOTEUSER', 'PASSWORD') #3 {main} thrown in /volume1/temp/ispconfig-ddns/update.php on line 36 On the server, I cannot see any log entry about the server error, except the /var/log/ispconfig/httpd/server.kainhofer.com/access.log: Code: 80.123.61.86 - - [20/Nov/2016:14:19:25 +0100] "POST /remote/index.php HTTP/1.1" 500 4059 "-" "PHP-SOAP/5.6.23" 80.123.61.86 - - [20/Nov/2016:14:21:37 +0100] "POST /remote/index.php HTTP/1.1" 500 4059 "-" "PHP-SOAP/5.6.23" However, I don't see any indication what exactly went wrong. Here is my whole DDNS script: Code: <?php #require('config.php'); $soap_location= 'https://server.kainhofer.com:8080/remote/index.php'; $soap_uri= 'https://server.kainhofer.com:8080/remote/'; $soap_user= 'REMOTEUSER'; $soap_password= 'PASSWORD'; if($argc<3){ print "Usage: php ./update.php HOST DOMAIN [IP]\n"; print "If not given, the ip address will be queried from icanhazip.com\n"; die(); } $ddns_host=$argv[1]; $domain=$argv[2]; if($argc>3){ $ip=$argv[3]; }else{ $ip=trim(file_get_contents("http://icanhazip.com/")); if(filter_var($ip, FILTER_VALIDATE_IP)===false){ die("Unable to retrieve public IP address (icanhazip.com returned $ip)\n"); } } $client=new SoapClient(null, array('location' =>$soap_location, 'uri' =>$soap_uri, 'trace' =>1, 'stream_context'=>stream_context_create(array('ssl'=>array('verify_peer'=>false,'verify_peer_name'=>false))), 'exceptions' =>1)); //try { $session_id=$client->login($soap_user, $soap_password); $zone_id=$client->dns_zone_get_id($session_id, $domain); $zone=$client->dns_zone_get($session_id, $zone_id); $records=$client->dns_rr_get_all_by_zone($session_id, $zone_id); $dns_record=null; foreach($recordsas$rec){ if($rec['type']=='A' &&$rec['name']==$ddns_host){ $dns_record=$rec; } } if(is_null($dns_record)){ $client->logout($session_id); die("Unable to find DNS record for host $ddns_host in domain $domain on the server...\n"); } if($dns_record['data']!=$ip){ $dns_record['data']=$ip; $dns_record['serial']=$dns_record['serial']+1; $client->dns_a_update($session_id, null, $dns_record['id'], $dns_record); $zone['serial']=$zone['serial']+1; $client->dns_zone_update($session_id, 0, $zone_id, $zone); // print("Successfully set DNS entry for host $ddns_host in domain $domain to $ip.\n"); }else{ print("IP address of $ddns_host.$domain already set to $ip.\n"); } $client->logout($session_id); //} catch (SoapFault $e) { // die('SOAP Error: '.$e->getMessage()."\n"); //} ?> Any idea what causes the Internal Server Error or where I might look for further information?
