I have application called unistat installed on my pc. I want to pass an argument from a web page and retrieve output from that program.
Is this possible?
How i can connect the website based on PHP to a remote desktop? ask to run .exe file by passing data and send output to specific location?
In order to access your local machine from the remote server, you're going to have to open up your router configuration settings and port forward all incoming port 80 traffic to your local web server's IP.
On your local machine, install PHP and set up an endpoint that runs the exec command, calling the .exe you wish to run.
You'd be wise to put this behind an authentication system, as it will be exposed to the www.
On the remote site, just fire a request off to the local machine's endpoint and the exec command will be run. Of course, if you have a dynamic IP, it's going to require constant maintenance.
See the following link about setting up custom protocols on Windows:
https://support.shotgunsoftware.com/entries/86754-launching-external-applications-using-custom-protocols-rock-instead-of-http
The idea would be that your web site could direct the browser to a special URL, i.e. unistat://my-data-goes-here and the application would be triggered with this data.
edit: better, MSDN link on the subject. http://msdn.microsoft.com/en-us/library/ie/aa767914(v=vs.85).aspx
edit2: Just realized you want to pipe the output from the EXE back to the webserver.... You may be better off building a browser extension. That, or writing a wrapper around unistat which can trap the output and submit it to a web service.

I have been trying to develop web pages locally (in Windows 10) and running in my local browser (chrome, vivaldi). Right now I have 3 different ways to run simple servers locally: php's built in server, python's http.server module, and vscode's LiveServer. When I run the php server, I can execute php code properly, as one would expect. But calling php urls using the other two, I get a "Save File" dialog! Where is that coming from? Instead of a simple "not found" I get the dialog. So I have two questions: (1) Why am I getting the save file dialog? (2) Is it possible to process php files using LiveServer or python's http.server module (which I don't expect can ever support php)
if the save dialog is being shown it's cause the server can't interpret php code. You have to check these servers configs to check their integration with PHP (if they they can do that).
Good questions. Erick has answered the 1st one. I'll just elaborate more on it and then answer the 2nd one.
Why do you get save file dialog?
At a high level, a web server is serving files. When serving HTML/CSS/JS files to the browser, life is easy. Your browser understands HTML/CSS/JS and knows how to render it for the user. If your browser was sent unprocessed PHP file (assuming that file was present), the browser won't know what to do with <?php .. ?> tags and such. So, the browser offers the user to download the file. Same thing with a zip file. If you went to http://someurl.com/abc.zip, if the webserver found that file under the root of someurl.com, it'll send it to the browser and the browser will offer the user to download it. There's more to it than just that.
So, how does a web server process PHP files? It depends on the web server, but the common thing is that they need help in processing PHP files. Web server is configured to send the request to php.exe or some other system such as PHP-FPM, which processes the file and returns back to the web server to send it to the user. Processing of the file converts echo "<div>$variable</div>"; to clean HTML <div>I am awesome</div>. This processing system (php.exe or PHP-FPM) tag team with web server to serve to the browser what it can render.
Is it possible to cross-render languages?
Yes, you can in multiple ways. One of the common ways is to find the best processing system for the language of choice. For example, PHP can be processed with PHP-FPM running as a service. So, http://someurl.com/test/index.php could run through PHP-FPM. Python may use WSGI and you may choose gunicorn to process Python files. In that case, your webserver can be asked to send python-related directories/subdomains directly to gunicorn (essentially a proxy).
Reverse proxy
Let's say you have multiple sites with multiple language needs.
http://py.someurl.com serves Python/Django
http://someurl.com serves straight HTML
http://ph.someurl.com services PHP
http://js.someurl.com is powered by NodeJS
py.someurl.com could run on the server using gunicorn web server (or other wsgi-friendly servers) on port 8000. Node could be serving using Express web server on port 9000.
You could run NGINX server that serves straight HTML and also serves ph.someurl.com by sending requests to PHP-FPM service. It can also be configured to take all requests to js.someurl.com and hand it off to http://localhost:9000 where Node will service the request and send output back to NGINX and NGINX can send the request to the browser. Similarly, requests to py.someurl.com can be sent to localhost:8000 where gunicorn processes the request and sends the request back to NGINX, which forwards the request to the browser.
From a user's perspective, all they know is the NGINX server. All the other things in the background are known to NGINX. NGINX, in that case, serves as a web server and a proxy.
I've got two Linux servers set up at the same datacenter. They're hooked up through a private switch, and they respond to each other on local IP addresses (192.168.0.N and 192.168.0.M).
Currently, I have a PHP file on Server N calling a PHP file on Server M via (basically) file_get_contents("http://$domain/$folder/$filename.php");, and that file runs a PHP script on the destination server. The problem with this, of course, is that it goes out over the internet, chewing up bandwidth in both the send and the reply. This is why I hooked them up with the private switch.
How can I set it up so that I can call the other file by replacing the $domain with the 192.168.0.M address? What settings do I have to change on Server N (Centos 6.6, running WHM and CPanel) in order for it to recognize that 192.168.0.M will shortcut to $domain's home folder on Server M?
This is commonly handled with split horizon DNS, where internal DNS queries get answered differently than external ones.
It's best to do this via a proper internal DNS server, but if you can't, you can adjust the hosts file on your servers (in Linux, /etc/hosts) to override the IP for the domain name.
i want to statically assign the ip address of my arch linux using php. i want to change the ip by using netmask,interface,broadcast,address & gateway.the user puts up the values into a html page.the html page posts the data to the php page.i want to change the ip using this data. HOW TO DO THIS!!
Files also can be used!! right?
..i was thinking of writing directly into the rc.conf using files!!...will this work and how??..i have my arch linux up with apache & php..any of the help is appreciated!!...thanku..:)
You should write yourself a shell-script and launch that via PHP, instead of trying to accomplish such a task with PHP itself.
If you don't know how to do that, you should ask a related question https://unix.stackexchange.com/.
Why would you use PHP to attempt to configure a server?? You should configure the server using pre-existing tools and commands that are designed for that purpose.
$su
# ifconfig <interface, tpyically eth0> down
# ifconfig eth0 192.168.1.105 netmask 255.255.255.0 up
# ifconfig eth0
You COULD wrap those commands in an exec() statement, but I don't see a PHP script having the necessary system permissions to complete them successfully.
In normal condition, you may be not able to do it from web server directly due to security.
There are several problems like permission on /etc files, security context of user in which apache run etc.
One secure way is to create cron task which will run under root account and regularly check for existence of some file which can be generated by apache (php).
Once file will appear you can reconfigure whatever using ifconfig within cron task with appropriate privileges based on content o this file.
Don't forget that your apache should be configured to use all interfaces and not realy on IP based VirtualHosts or you will immediately lose connection to it.
I want to write either a perl (CGI) or php script on a server to behave like a proxy server. I want to be able to enter the hostname and port on firefox proxy settings (or IE, chrome, whatever) and then go to a site, and have my webserver forward the request to another server, and forward the response back to the client. This way, I am basically using my server as a proxy server. Is there a perl or php script that can do this? If so, what?
Do not suggest anything along the lines of PHProxy or Glype.
I don't want a server that I go into with my browser and enter a URL to browse. That's a big NO-NO.
The CPAN module HTTP::Proxy implements a simple HTTP proxy server that you can start and run out-of-the-box.
Is there an easy forwarding/transparent php proxy script that I can host on my web server? These are my conditions:
I'm using free web hosting, so I have pretty much no control over my machine. Otherwise I could use Perl's HTTP::Proxy module. This means no root password. It does run php though.
I already have a server running on port 80. What I mean is I would like to put a php script as index.php on my server that will forward all requests.
I don't want a script like PHProxy or Glype where I go to the site, then enter a URL. I want a server so I can enter proxy.example.com:80 in Firefox's or IE's or whatever's proxy settings and it will forward all requests to the server.
Preferably (though not fatal if not possible) I would like for it to pass on the USER_AGENT environmental variable (That's the browser) instead of setting itself to be the USER_AGENT
I can't start a new Daemon. My server won't allow it.
Is there a script that will do this? If so, which?
No, I'm fairly sure this is not possible on shared hosting. It will fail your condition number 3. This needs support on web server level (e.g. using Apache's mod_proxy)
For this to work, you would have to set up the remote server to be able to deal with proxied requests. No sane web server will offer that possibility.
