Hi all
I've a flow that's communicating to an application behind TCP IP...
I'm communicating to an TCP Server, with this information: 172.26.49.142:45013
The communication is Synchronized... so I'm using TcpClientOutput and TcpClientRecieve with that IP and Port configured...
But the problem is that I'm getting a timeout response with my Message Broker flow... but using the telnet program, of my windows 7, it works fine with the same message...so it's responding something.
I've my windows firewall down...
I've tested using the TCP Configurable Service and setting Minimum number of connections to 1, but it didn't work  ...
Any ideas? Why am I getting the timeout Response?
PD: I've taken as example the TCPIPClient Flows that comes with the toolkit...
Regards everybody!! |

I've made a packaging intercepting, with wireshark...and the response of the TCP server application comes from a port distinct from the initial port request setted from the TCP Client Out node of the broker...
Can the TCP Client Receive node, be setted to use the same "negotiation" port from the TCP Communication established between the Message Broker flow and the external Application ?
Is there any way to achieve that?
The TCP Server application is a HSM, so it sends the reponses from the first free port that it finds... that why I need to find a way to use the same connection, without hardcoding the Port of the response message from the TCP Server Application.
Regards... |

Has anybody had a problem similar like this one?
Is there any way to use the same connection , without needing to set the port, in a TCP Client Receive node?
Or do I have to use a Java Compute node and made it to the "old fashioned way"?
Regards. |

| TCPIP nodes do not directly create or manage any TCP/IP connections, but acquire them from the connection manager's internal pool. For example, two output nodes using the same connection details share the same connection manager. The TCPIP nodes can define the connection details to be used by specifying the following values: Host name and port |
Port number must be included.

Are you closing the connection after receiving a message?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

I'm not getting the response from The server in the Message Broker Flow:(... because the server sends the response by differents TCP Port numbers generated randomly... so I can't tell the node TCP Client Receive the exact port number of the response message.
I only see the respose is in a different port randomly generated, by my Sniffer program.
How can I solve that problem of not knowing the port of the respose in the TCP Client Receive? Is there any way ? (in Java you use the same connection but the response can come from any port... you only need to set the port on the TCP Request... )

Yes, that's my question ... and how can I know at runtime the port negociated in the connection? Is there any way ?
I've made a debug and there's nothing regarding the receiver port in the LocalEnvironment... so I think there's no way... or may be there's some way of doing that but I didn't find it -i hope so-...
I've read the documentation of the nodes, but I haven't found anything for my problem...
If someone has any idea... please post it...
Regards everybody! |

There's comments in a couple of places about settings on the TCPIPClientOutput to reserve the connection.
It is simply not possible that the Server application chooses a port at random and gives any of it's clients absolutely no information about which port to use. |

I've tested all of the possibilities regarding Reserving the connection in the TCP Output Node, but no one worked.
So I'm starting to think to use a Java Compute node to communicate (write and read) from the socket connection... |

You should open a PMR.
Unless the Server includes Java code that already does what you are expecting, it's not clear that you have enough information to accomplish what you're trying to do even with Java code. |
