SMBClient connect times out after 5 seconds

[cmcgowen]

With this code:

SMBClient client = new SMBClient(SmbConfig.builder()
                    .withSigningRequired(true)
                    .withDfsEnabled(true)
                    .withMultiProtocolNegotiate(true)
                    .withTransactTimeout(120, TimeUnit.SECONDS)
                    .build());

Connection connection = client.connect(remoteRepositoryInfo.hostname);

I am getting "java.net.SocketTimeoutException: connect timed out" 5 seconds after the call.

This is only happening when trying to connect to a specific machine. It works when connecting to different machine.

From the machine where the java code is running, I am able to connect to the share with NET USE, so the machine should be reachable.

I have tried using the hostname of the machine as well as the IP address in the call to connect() with the same results. I originally tried using JCIFS, and that was able to connect to the machine, but I ran into issues when trying to list the files in a shared folder, so I switched to smbj.

Is there something else that I'm missing?

Can you provide some detailed trace level logging for the connection attempt?

I've got exactly the same problem.

The stackstrace of the exception is:

Is there a way to change the connection timeout? Thanks
