I have built Catcoind (a fork of the Bitcoin / project) and I can access the commands in my terminal by doing this from root:
cd catcoin/src
./catcoind -daemon
That will start Catcoind, open the port, and allow me to type commands like './catcoind getdifficulty', but I want to access them from a PHP JSON-RPC client running on another server. The code I currently have there is:
<?php
require_once 'jsonRPCClient.php';
$catcoin = new jsonRPCClient('http://RPCUSER:RPCPASS#IP:PORT');
print_r($catcoin->getinfo());
echo $catcoin->getdifficulty();
My config file for the Catcoind build on Ubuntu is:
server=1
rpcuser=USER
rpcpassword=PASS
rpcssl=0
rpcallowip=*
bind=IP:PORT
externalip=IP
proxy=IP:PORT
port=PORT
rpcconnect=IP
When I run the code, it says that it failed to open the stream / connection refused. The config for Catcoind is at location ~/.catcoin/catcoin.conf. Any ideas? I know this is confusing, but I have really everything done but allowing external IPs to access the API. Thanks! :D
You don't need all these things to be written in conf file just use following
server=1
daemon=1
rpcuser=<user_namer>
rpcpassword=<password>
rpctimeout=30
if connecting from remote host do add following line
rpcallowip=<remote_ip_address>
save and exit from conf file and restart daemon by first stopping it catecoind stop and then catcoind start
Are external IP allowed? If not make sure that the IP is allowed so that it can call the api. The error failed to open the stream / connection refused usually means that the ip and everything is correct but the server rejected the connection.

I would like to make a web interface in PHP to see the FreeSWITCH activities (calls, etc), possibly hosted on a different server than the one where FS is running.
I've seen the server status on the FS server using command line (php single_command.php status), but now I would like to see this status from another server.
When I try to copy ESL.php file to this remote server and try to check the status, I get this error message:
Fatal error: Call to undefined function new_ESLconnection() in
/var/www/freeswitch/ESL.php on line 127
This is my index.php file:
<?php
ini_set('display_errors', 1);
$password = "ClueCon";
$port = "8021";
$host = "192.168.2.12";
require_once('ESL.php');
set_time_limit(0); // Remove the PHP time limit of 30 seconds for completion due to loop watching events
// Connect to FreeSWITCH
$sock = new ESLconnection($host, $port, $password);
// We want all Events (probably will want to change this depending on your needs)
$sock->sendRecv("status");
// Grab Events until process is killed
while($sock->connected()){
$event = $sock->recvEvent();
print_r($event->serialize());
}
?>
I undestand that the webserver doesn't have FreeSWITCH installed, so the error message is obvious, but i don't see how to access to this information from this webserver.
Thank you for your help.
Depending upon your need you can use either Inbound or Outbound socket. I do not know much about PHP and FS Event Socket but yeah tried enough with python. I highly recommended to go through thislink.
So if you just want to do small task like initiating a call, bridging any two given number etc i think you should go with Inbound socket(making cli command from your web server to freeswitch server) or mod_xml_rpc.
And if you want to have full control of everything that happens on FS server like showing live call status and modifying their states or say a complete interactive telephony dashboard then you should go with Outbound socket.(Your FS server will send all events to your web server.)
However in your case problem is I think you did not properly build the php ESL module.
this link might help you installing ESL
Rather than using ESL, you might want to consider using the XMLRPC. The connection is very straight forward:
https://wiki.freeswitch.org/wiki/Freeswitch_XML-RPC
The credentials for the XMLRPC are in your autoloads_configs/xml_rpc.conf.xml
I use third part framework (exe file) for conneting one php application with taxt service.
Framework is open source, exe file sign xml, give soap cover and send it to central information tax system.
When i open this in batch file (run.bat), all working good:
Raverus.FiskalizacijaDEV.EXE.exe GetInvoice "" "C:\xampp\htdocs\get\racun.xml" "C:\xampp\htdocs\get\OutInvoice.xml" true true "C:\xampp\htdocs\get\certifikat.pfx" "Pwd"
but when i open in PHP using "echo exec('run.bat');" server give me this error:
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
Does anybody have idea how i can resolve this? When i mannualy open batch file (in windows) all working. I use Xampp server.
The PHP user doesn't have the needed configuration or access rights.
If you are unsure which user is running your PHP script, you can use something like this to find out:
<?php
echo '<pre>';
system('set', $retval);
echo ' </pre>';
it should give out information as to which user your PHP is using. Then set up the env for that user so he can run your batch file. This might include importing the certificate for that user.
I am currently opening and writing a text file into my local server with the following:
$mypath="sms_file\\cbsms_";
$fp = fopen($file_name.'.txt', "w");
fwrite($fp, $value. "\r\n");
fclose($fp);
I want to now copy that file to a remote server like /home/project on 10.10.18.23 (home network)
Assuming that I have R/W access in that directory, what would be the best way of achieving this?
The remote server needs to know that there is a request coming in to store a file on it. There are several possibilities here, the easiest would be to run a FTP server.
Another option would be to use the exec() function call scp on the command line (provided you have exchanged ssh keys with the remote server).
Another option would be to create a PHP page on the remote server that accepts POST requests with files and stores them. You must provide your own security measures in this case.
If you can mount the remote host as a permanent volume (via NFS or CIFS), you can use the regular PHP copy() function.
You can try using exec() to run an SCP command:
exec('scp /path/to/file.txt user#homenetworkhost:/home/project/file.txt');
// Obviously, you'll have to set up your SSH permissions and for 'user#homenetworkhost' you'll want to change it to your home network's user and host names.
By the looks of your exmample, I would say your PHP server is on Windows (looking at the backslash in $mypath="sms_file\\cbsms_";), and your remote host is UNIX/LINUX (looking at forward slashes and location /home/project). I would suggest setting up SSH or FTP on the remote host and rather use those protocols than copying it to a network location. Your PHP server (Windows box) will then have to communicate via SSH/FTP and copy the file.

Here is a snippet of my code
$fp = fsockopen($s['url'], 80, $errno, $errstr, 5);
if($fp){
fwrite($fp, $out);
fclose($fp);
When I run it, it outputs:
unable to connect to www.mydomain.net/1/file.php:80 (php_network_getaddresses: getaddrinfo failed: Name or service not known
I'm using this to submit GET data to the $s['url']
I can't figure out why. Any help would be greatly appreciated.
You cannot open a connection directly to a path on a remote host using fsockopen. The url www.mydomain.net/1/file.php contains a path, when the only valid value for that first parameter is the host, www.mydomain.net.
If you are trying to access a remote URL, then file_get_contents() is your best bet. You can provide a full URL to that function, and it will fetch the content at that location using a normal HTTP request.
If you only want to send an HTTP request and ignore the response, you could use fsockopen() and manually send the HTTP request headers, ignoring any response. It might be easier with cURL though, or just plain old fopen(), which will open the connection but not necessarily read any response. If you wanted to do it with fsockopen(), it might look something like this:
$fp = fsockopen("www.mydomain.net", 80, $errno, $errstr, 30);
fputs($fp, "GET /1/file.php HTTP/1.1\n");
fputs($fp, "Host: www.mydomain.net\n");
fputs($fp, "Connection: close\n\n");
That leaves any error handling up to you of course, but it would mean that you wouldn't waste time reading the response.
I had a similar problem on my local testserver and local testdomains e.g.: www.testdomain.loc with the function GetImageSize();
Solved it by adding the hostname in the hosts file on the local server:
In the file /etc/hosts I added:
192.168.1.1 www.testdomain.loc
If you only want to submit GET data to the URL, you should use something straightforward like file_get_contents();
$myGetData = "?var1=val1&var2=val2";
file_get_contents($url.$myGetData);
Had such a problem (with https://github.com/PHPMailer/PHPMailer), just reload PHP and everything start worked
for Centos 6 and 7:
service php-fpm restart
$url = "http://user:pass#www.example.com/abc.php?var1=def";
$contents = file_get_contents($url);
echo $contents;
you are trying to open a socket to a file on the remote host which is not correct. you could make a socket connection (TCP/UDP) to a port number on a remote host. so your code should be like this:
fsockopen('www.mysite.com', 80);
if you are trying to create a file pointer resource to a remote file, you may use the fopen() function. but to do this, you need to specify the application protocol as well.
PHP provides default stream wrappers for URL file opens. based on the schema of the URL the appropriate stream wrapper will be called internally. the URL you are trying to open does not have a valid schema for this solution. make sure there is a schema like "http://" or "ftp://" in it.
so the code would be like this:
$fp = fopen('http://www.mysite.com/path/file.txt');
Besides I don't think the HTTP stream wrapper (that handles actions on file resources on URLs with http schema) supports writing of data. you can use fread() to read contents of a the URL through HTTP, but I'm not sure about writing.
EDIT:
from comments and other answers I figured out you would want to send a HTTP request to the specified URL.
the methods described in this answer are for when you want to receive data from the remote URL. if you want to send data, you can use http_request() to do this.
I was getting the same error of fsocket() and I just updated my hosts files
I logged via SSH in CentOS server. USERNAME and PASSWORD

In my case this error caused by wrong /etc/nsswitch.conf configuration on debian.
I've been replaced string

with

and everything works right now.
Try to set ENV PATH. Add PHP path in to ENV PATH.
In order for this extension to work, there are DLL files that must be available to the Windows system PATH. For information on how to do this, see the FAQ entitled "How do I add my PHP directory to the PATH on Windows". Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the system's PATH), this is not recommended. This extension requires the following files to be in the PATH: libeay32.dll

in simple word your site has been blocked to access network. may be you have automated some script and it caused your whole website to be blocked. the better way to resolve this is contact that site and tell your issue. if issue is genuine they may consider unblocking
I had a similar problem when connecting to a local MySQL database, only changed the url for the ip address 127.0.0.1 and it worked. You could change the url for the ip address of the server.
I'm making a GWT project that uses PHP to connect to a DB2 database. When I compile the project and deploy it to the server (copy the contents of the WAR directory over), it works fine, obviously in hosted mode I run into the SOP issue since GWT is on port 8888 while the php script is running on port 80.
I'm trying to get the -noserver option to work but I must be missing something.. I went back and created the basic sample app from the command line (webApplicationCreator -out /home/mike/gwt/sample1)
I edited the build.xml to include the -noserver and -port 80 arguements for devmode. I want my app to be hosted at localhost/sample1 so I edited the -startupUrl to the whole URL I want to use: http://localhost/sample1/sample1.html
I compiled (ant), copied over the sample1.html, sample1.css from war to the webserver sample1 directory, and the (md5).gwt.rpc, clear.cache.gif, sample1.nocache.js and hosted.html files from the war/sample1 to sample1/sample1 directory as described in the GWT documentation (no history.html file was created).
I then run ant devmode from the project directory (/home/mike/gwt/sample1)
I can get to the sample1.html page, but when I click the button to send the name to the server it returns with
Remote Procedure Call - Failure
Server replies:
An error occurred while attempting to contact the server. Please check your network connection and try again.
I turned on firebug and it's returning a 404 for http://localhost/sample1/sample1/greet. This is where I'm stuck.. this file obviously doesn't exist on my webserver.. but why? Isn't this something that is supposed to be getting compiled by GWT?
Can anyone give me a hand? Thanks!
So, basically you've copied over the client-side of a client/server application. When your GWT client application attempts to make a Remote Procedure Call (RPC) to the server to a greeting service that is part of the initial sample, it can't find that service.
If you wanted to copy that service over, you'd need to have a Java application server, copy over the GreetingService, the web.xml that references it and possibly a few other things (I'd have to check in more detail). That doesn't sound like what you actually want, so either you'll want to build a GWT-RPC service in PHP that responds to that URL, or remove the reference in the GWT code to RPC call to the greeting service.
With a PHP back-end, you're probably not going to use GWT-RPC, I'm guessing that you're more likely to use JSON or XML, and if that's the case, then I'd go with removing the RPC call altogether for now.
Does this all make sense? Feel free to ask for further clarification.
To solve the SOP issue, I used the HttpProxyServlet to proxy the HTTP requests to my webserver through the development server.
Download httpProxyPackage.jar, copy it into WEB-INF/lib/, and configure it like so in WEB-INF/web.xml (this is for the StockWatcher tutorial, assuming your web root is the folder that contains the StockWatcher directory):
<servlet>
<servlet-name>jsonStockData</servlet-name>
<servlet-class>com.jsos.httpproxy.HttpProxyServlet</servlet-class>
<init-param>
<param-name>host</param-name>
<param-value>http://localhost/StockWatcher/war/stockPrices.php</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>jsonStockData</servlet-name>
<!--
http://127.0.0.1:8888/stockPrices.php in dev mode
http://gwt/StockWatcher/war/stockPrices.php in prod mode
-->
<url-pattern>/stockPrices.php</url-pattern>
</servlet-mapping>
Then redefine your JSON URL as:
GWT.getHostPageBaseURL() + "stockPrices.php?q=";
instead of:
GWT.getModuleBaseURL() + "stockPrices.php?q=";
It’s maybe not the best way, but if it can get someone else started… There was another way using php-cgi, but I didn’t have it installed.
