TCP/IP Client

Description​

Environment entries of type TCP/IP client are used to declare the parameters to gain a connection. The entry is used by Channels, which act as client and establish connections to external systems e.g. from the TCP Sender Channel. Its is also used from the TCP-Server Channel if it works in client mode!

Purpose of object​

It is used from channels which need to establish a TCP or TLS connection to an external system.

Step by Step​

  1. Create an Environment entry of type TCP/IP connection.

  2. Fill in the host or IP of the intended system, e.g. localhost or 192.123.345.67.

  3. Fill in the port of the system, which should be accessed.

  4. Select the connection type:

    • TCP: Core protocol of the Internet protocol suite.
    • TLS(different versions): Cryptographic protocol to provide communication security.
    • SSL: Predecessor of TLS.

  5. Security Settings: Decide whether to use Authentication by enable the checkbox.

  6. In case of Authentication:

    The certificate Check Panel allows a user to configure the client side HTTPS connection details.

    • User-Credentials (type=Technical login): The public/private keypair in pkcs#12 format which should be used for authorization.

    • Trusted server (optional, type=Trusted server): This option allows to check the server's public key certificate which is presented by the server when the client makes a request.

    • Trusted signer (optional, type=Trusted server): Checks whether the server's certificate has been signed by the given certificate and thus can be trusted.

    • Check certificate chain (optional): check if the certificate chain is correctly signed (certificate n is signed by certfificate n + 1)

    • Check validity** (optional): If set, then check if the certificate is expired.

    • Check signers against trust store: If set, then check that the one certificate in the certificate chain (typically the last one) is contained in the trust store.

    • Cipher Suites (optional): Enforcing specific Cipher Suites to be used in TLS. The cipher suites are added as comma separated values in the text box(e.g. "TLS_ECDH_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_DHE_RSA_WITH_AES_256_CBC_SHA").

  7. Click Test: An alert window will appear, which shows whether the test of the connection was successful.

  8. If the test was successful. Click on Finish.
