WinSCP based same connection using account name, passphrase and private key for connection. But trying from code am getting this exception continuously.
Code:
try

session.connect();
System.out.println("session is alive:" + session.isConnected());
channel = session.openChannel("sftp");
channel.connect();
channelSftp = (ChannelSftp) channel;
channelSftp.connect();
channelSftp.chmod(777, depDir);
}
catch (Exception e1)
{
e1.printStackTrace();
System.out.println("Manual Exception in updateDepositedFilePermission:" + CommonUtil.getExceptionString(e1));
}
Output:
session is alive:true

Not sure it's the main problem, but you are calling Channel.connect() twice.
First here:
channel.connect();
And again here:
channelSftp.connect();
Remove the second call.

I am trying to use MQTT directly to connect to IOT central.
I just followed below documentation,
https://learn.microsoft.com/en-us/azure/iot-central/concepts-connectivity#connect-a-single-device
https://www.instructables.com/id/Azure-IoT-Hub-Set-Up-MQTTfx-Sigfox-Callback-and-Dr/
https://github.com/MediaTek-Labs/aws_mbedtls_mqtt/pull/9/files?short_path=04c6e90
https://docs.azure.cn/zh-cn/articles/azure-operations-guide/iot-hub/aog-iot-hub-howto-connect-with-tool-mqtt-fx (Translate to english)
Above documentation I used dps_cstr tool from github to generate connection string with SAS token from this link
https://learn.microsoft.com/en-us/azure/iot-central/tutorial-add-device#prepare-the-client-code
Broker Address = saas-iothub-947867dc-cd5d-446c-90ff-e0f964f020fe.azure-devices.net
Broker port = 8883
Client ID = 92ff3e25-00e5-4249-9074
User Name = saas-iothub-947867dc-cd5d-446c-90ff.azure-devices.net/92ff3e25-00e5-4249-9074
MQTT Version = 3.1.1
Password = OfAlY0BGstmuinZzOcdDDf
I have configured the MQTT.fx with connection profile for iot central by using above connection string and details.
Attached the snap of that
When i try to connect to this, I am getting an error "Not authorized to connect".

I have just finished a test using a MQTT.fx client connected to the Azure IoT Central.
Based on the doc Using the MQTT protocol directly the password must be in the following format, see example:
SharedAccessSignature sr={your hub name}.azure-devices.net%2Fdevices%2FMyDevice01%2Fapi-version%3D2016-11-14&sig=vSgHBMUG.....Ntg%3d&se=1456481802
You have to generate the above password (sas token) string. You can use the following helper function:
string sasToken = SharedAccessSignatureBuilder.GetSASTokenFromConnectionString(connectionString);
public sealed class SharedAccessSignatureBuilder
{
public static string GetHostNameNamespaceFromConnectionString(string connectionString)
{
return GetPartsFromConnectionString(connectionString)["HostName"].Split('.').FirstOrDefault();
}
public static string GetSASTokenFromConnectionString(string connectionString, uint hours = 24)
{
var parts = GetPartsFromConnectionString(connectionString);
return GetSASToken(parts["HostName"], parts["SharedAccessKey"], parts.Keys.Contains("SharedAccessKeyName") ? parts["SharedAccessKeyName"] : null, hours);
}
public static string GetSASToken(string resourceUri, string key, string keyName = null, uint hours = 24)
{
var expiry = GetExpiry(hours);
string stringToSign = System.Web.HttpUtility.UrlEncode(resourceUri) + "\n" + expiry;
HMACSHA256 hmac = new HMACSHA256(Convert.FromBase64String(key));
var signature = Convert.ToBase64String(hmac.ComputeHash(Encoding.UTF8.GetBytes(stringToSign)));
var sasToken = String.Format(CultureInfo.InvariantCulture, "SharedAccessSignature sr={0}&sig={1}&se={2}", HttpUtility.UrlEncode(resourceUri), HttpUtility.UrlEncode(signature), expiry);
if(!string.IsNullOrEmpty(keyName))
sasToken += String.Format(CultureInfo.InvariantCulture, "&skn={0}", keyName);
return sasToken;
}
#region Helpers
private static Dictionary<string, string> GetPartsFromConnectionString(string connectionString)
{
return connectionString.Split(new[] { ';' }, StringSplitOptions.RemoveEmptyEntries).Select(s => s.Split(new[] { '=' }, 2)).ToDictionary(x => x[0].Trim(), x => x[1].Trim());
}
// default expiring = 24 hours

I want to start a RabbitMQ source and then sink, but I not able to perform first step i.e starting Rabbit MQ source . RabbitMQ server is running and I can see dashboard as well.
My code is as below

RMQConnectionConfig connectionConfig = new RMQConnectionConfig.Builder()

"queue", // name of the RabbitMQ queue to consume

How to Resolve it. And make to send the otp code to My Gmail account?
Is There any other method to send the generated otp digit to Gmail or How to resolve The above problem. Please guide me in this issue.
I ran into a strange problem. We have to poll a mailbox every 10 minutes and check for new mails (POP3, IMAP). We tested our implementation with several mail providers (gmail, 1and1, web.de, gmx, ...) and all worked fine.
Now we have to use a mailbox from outlook.office365.com with POP3 and SSL. Starting our service everything is working, but after a few hours the mailbox check throws errors while opening the mailbox store.

This is my createStore method:

{
if ( store == null )
{
store = session.getStore( authType.getType() );
}
if ( store != null && !store.isConnected() )
{
try

}
catch ( MessagingException e )
{
store = null;
logger.error( "Cannot connect to configured mailbox: [Host: " + popHost + ", Port: " + popPort + ", User: " //$NON-NLS-1$ //$NON-NLS-2$ //$NON-NLS-3$
+ user + "]" ); //$NON-NLS-1$
logger.debug( "", e );
}
}
}
On store.connect(..) the error occurs.
Anyone out there with an idea what can couse this error?

Updating the BouncyCastle dependencies solved the problem.
It looks like the BouncyCastle provider has a problem:
Caused by: java.security.InvalidAlgorithmParameterException: parameter object not a ECParameterSpec
at org.bouncycastle.jce.provider.JDKKeyPairGenerator$EC.initialize(Unknown Source)
Is your program doing anything to change the BouncyCastle configuration while it's running? If not, perhaps it's a bug in BouncyCastle? Otherwise, I don't know what would cause it to work for awhile and then fail.
Check if you have an outdated org.bouncycastle lib in your classpath (incompatible with your java version).
See http://iwang.github.io/support/2014/03/14/cxf-cause-https-error.html for an in-depth explanation.
