Davy, I just pushed a second commit to the PR that will log the port from the local address of the socket being used by the sender, which I think is what you mean by the client port.
If you turn on debug for PutTCP you will see something like... o.apache.nifi.processors.standard.PutTCP PutTCP[id=95463da0-015e-1000-8723-0a2baf6c832f] Connected to local port 57280 I only performed the logging after successful connection because I'm not sure the ramifications of trying to obtain the local SocketAddress while finishConnect is still returning false, so I guess the logging wouldn't really help in the case where the exception was thrown. https://github.com/apache/nifi/pull/2159 -Bryan On Mon, Sep 18, 2017 at 2:18 PM, ddewaele <ddewa...@gmail.com> wrote: > Thx a lot for the quick response.....
