Centos with Apache server.

Php version 4.3

wanting to send data out a socket for reading by another computer Program (windows).

I read the data from a third computer (windows). On the Centos server box I manipulate the data and want to send out to be read by a program on a windows machine. My problem is that I cannot open a socket to write to.

error is -

Warning: fsockopen(): unable to connect to 192.168.1.102:30003 in reroute.php on line 48


I have disabled the firewall, error the same.

192....102 is the centos server.

replacing 192.168.1.102 with localhost same error.

The php script is being run with root.

thanks for your help.

Hi there,

that means, either there is no service listening on port 30003 of IP 192.168.1.102, or if it is, the communication between that host and the one which the script is running on is blocked.

Thanks Doc,

Is there a way to send data to a port so it can be read by a third party software that listens on a specific port?

Typo? Should be the address of the windows PC. Using localhost is the same as sending data to the CentOS PC and not the windows PC.

Make sure the windows PC firewall allows connections on the desired port.

You can test your program on the CentOS server by using the netcat (nc) command in a second console window.
nc -lp 30003
Then when you run your program you should see the data. Use localhost or the IP address of the CentOS server.

Is the server on the windows PC expecting TCP or UDP?

I need to clarify.

Computer 1- windows - runs an application that sends data out its port 30003.

computer 2- centos linux with php, apache, and mysql. This is where the script is run. The script in question reads the data from computer 1, manipulates the data and sends it to a tcp port (at least thats what I am trying to do).

computer 3- windows - runs an application that reads the new data and forwards the data to a database over the internet.

computer 2 ip is 192.168.1.102. Thus the error

Warning: fsockopen(): unable to connect to 192.168.1.102:30003 in reroute.php on line 48

----
Hope that clarifies.

thanks for helping.

As already stated there doesn't seem to be any service running on port 30003 of the CentOS computer. The address should be one of the windows boxes depending on if you are reading or writing.

Can I create a service that will send the data out of the centos box on port 30003

with a php script?

an example would be most helpful.

Yes. This might help.
