I am trying to connect to the ejabberd server and using Smack Api. Below is the code for connection to server. After setting username, Host, and localhost Service, i am trying to show a Toast whenever it is connected. On debugging, neither Toast is shown nor any exception... please have a look at code below
XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
.setUsernameAndPassword("alien#localhost", "alien")
.setServiceName("localhost")
.setHost("192.168.1.xx")
.setPort(5222)
.setDebuggerEnabled(true)
.build();
AbstractXMPPConnection conn2 = new XMPPTCPConnection(config);
try {
conn2.connect();
conn2.login();
if(conn2.isConnected())
{
Toast.makeText(ChatClient.this,"isConnected",Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(ChatClient.this,"Failed",Toast.LENGTH_LONG).show();
}
Following are dependencies which i have used in my project,
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile "org.igniterealtime.smack:smack-android:4.1.0"
// Optional for XMPPTCPConnection
compile "org.igniterealtime.smack:smack-tcp:4.1.0"
// Optional for XMPP-IM (RFC 6121) support (Roster, Threaded Chats, …)
compile "org.igniterealtime.smack:smack-im:4.1.0"
// Optional for XMPP extensions support
compile "org.igniterealtime.smack:smack-android-extensions:4.1.0"
}
My domain is ( 192.168.***.2*:5280/admin )..thank you in advance :)

I created Shopify app with Nodejs tutorial. It uses SQLite for storage. But now I want to change to MySQL database. I use npm #shopify/shopify-app-session-storage-mysql and npm mysql2 to connect database.
I'm trying to query to database, and it return error about scope as below.
Error about scope in node_module of #shopify/shopify-app-session-storage-mysql: node_modules/#shopify/shopify-app-session-storage-mysql/node_modules/#shopify/shopify-api/lib/auth/scopes/
This is error
How can I fix it? Thank you so much
This is my code
init: async function () {
/* Initializes the connection to the database */
// this.db = this.db ?? new sqlite3.Database(DEFAULT_DB_FILE);
this.connection = this.connection ??
new mysql.createConnection('mysql://username:password#localhost/name_database');
I have made an asp.net core app that runs perfectly in my windows machine. I need to deploy this app on a Linux machine. My problem comes when migrating my tables into MySQL server on the Linux machine. I have the Linux machine for production purposes and I need MySQL server for users handling. I have created a database but when I run the command dotnet ef database update to migrate my tables into this database I see the following error:
My connection string used for the connection to my database is the following :
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=ElectransUsers;Trusted_Connection=True;MultipleActiveResultSets=true"
},
If I change the connection string writing localhost instead of localdb I see the following error:
If I remove mssqllocaldb I see the following error:
And my Configure method in the Startup.cs script is the following:
public void ConfigureServices(IServiceCollection services)
{
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(
Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<IdentityUser, IdentityRole>()
//.AddDefaultUI(UIFramework.Bootstrap4)
.AddEntityFrameworkStores<ApplicationDbContext>();
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
services.AddSignalR();
}
Does anyone know what I have to change in the connection string to be able to do the migration?
Thank you.
I have changed my conection string and code:
services.AddDbContext<DbContext>(options =>
options.UseMySql(Configuration.GetConnectionString("MysqlConnection"),
mySqlOptions =>
{
mySqlOptions.ServerVersion(new Version(10, 1, 38), Pomelo.EntityFrameworkCore.MySql.Infrastructure.ServerType.MySql); // replace with your Server Version and Type
}));
"MysqlConnection": "Server=localhost;Database=ElectransUsers;User=root;Password=my_password;"
But I see the following error:
Do you know what I'm doing wrong?
Consider using a MySQL connection provider. Example code snippet here.
services.AddDbContext<DbContext>(options =>
options.UseMySql(configuration.GetConnectionString("MysqlConnection"),
mySqlOptions =>
{
mySqlOptions.ServerVersion(new Version(5, 1, 73), ServerType.MySql); // replace with your Server Version and Type
})
My Connection String
"MysqlConnection": "server=194.36.12.123;port=3306;database=database_name_here;uid=user_name_here;password=password_here"
I am using Pomelo.EntityFrameworkCore.MySql Package
Here is documentation
I am using docker-java API to execute docker API in my project. I didn't find any suitable method which lists down docker CPU memory usage as
GET /v1.24/containers/redis1/stats HTTP/1.1 with the help of docker-java API
Dependency
compile group: 'com.github.docker-java', name: 'docker-java', version: '3.1.2'
Code
public static void execute() {
DockerClient dockerClient = DockerClientBuilder.getInstance().build();
dockerClient.statsCmd("containerName");
}
I didn't get any output
Tell me how to execute docker stats with docker-java api
This works for me
public Statistics getNextStatistics() throws ProfilingException {
AsyncResultCallback<Statistics> callback = new AsyncResultCallback<>();
client.statsCmd(containerId).exec(callback);
Statistics stats;
try {
stats = callback.awaitResult();
callback.close();
} catch (RuntimeException | IOException e) {
// you may want to throw an exception here
}
return stats; // this may be null or invalid if the container has terminated
}
DockerClient is where we can establish a connection between a Docker engine/daemon and our application.
By default, the Docker daemon can only be accessible at the unix:///var/run/docker.sock file. We can locally communicate with the Docker engine listening on the Unix socket unless otherwise configured.
we can open a connection in two steps:
DefaultDockerClientConfig.Builder config
= DefaultDockerClientConfig.createDefaultConfigBuilder();
DockerClient dockerClient = DockerClientBuilder
.getInstance(config)
.build();
Since engines could rely on other characteristics, the client is also configurable with different conditions.
For example, the builder accepts a server URL, that is, we can update the connection value if the engine is available on port 2375:
DockerClient dockerClient
= DockerClientBuilder.getInstance("tcp://docker.baeldung.com:2375").build();
Note that we need to prepend the connection string with unix:// or tcp:// depending on the connection type.
I am trying to set up an ASP.Net Core application to read in configuration settings from a json file. I am using VS2015 and .NetCore 1.0 (with .Net Core Tools preview 2). I am having problems getting a simple piece of boiler plate code to compile.
I am using the following code, which was published at
http://asp.net-hacker.rocks/2016/03/21/configure-aspnetcore.html
public Startup(IHostingEnvironment env)
{
// Set up configuration sources.
var builder = new ConfigurationBuilder()
.AddJsonFile("appsettings.json")
.AddEnvironmentVariables();
if (env.IsDevelopment())
{
// This will push telemetry data through Application Insights
// pipeline faster, allowing you to view results immediately.
builder.AddApplicationInsightsSettings(developerMode: true);
}
Configuration = builder.Build();
}
However, the IDE/compiler complains that 'the name "Configuration" does not exist in the current context' (last line of code). The only suggestion from the IDE is to include Microsoft.Extensions.Configuration. However this is a namespace which does not contain an object or property named "Configuration".
In addition 'AddApplicationInsightsSettings' fails with does IConfigurationBuilder not contain a definition for AddApplicationInsightsSettings and no extension method AddApplicationInsightsSettings accepting a first argument of type IConfigurationBuilder could be found
Any suggestions please ?
Thanks
Simply add Configuration property to your Startup class, tutorial has missed this 'step':
public IConfigurationRoot Configuration { get; set; }
ConfigurationBuilder.Build() method just returns instance of IConfigurationRoot, that you should save, if need to get settings further in Startup class (in ConfigureServices method for example).
Regarding second error, looks like you didn't add the Application Insights dependency:
{
"dependencies": {
"Microsoft.ApplicationInsights.AspNetCore": "1.0.0"
}
}
I'm trying to connect to a SFTP server via an SSIS package. The package executes WinSCP with the following connection string in a .txt file:
open sftp://username:fc$#6444#example.com:22
However the package keeps failing without being able to connect. Is it something to do with the special characters in the password?
I am able to connect to a different SFTP if I replace the string so I know it must be something to do with the syntax above. I've tried putting double quotes around the string as follows without any success:
open "sftp://username:fc$#6444#example.com:22"
I had to do this too, for one of my work projects recently. We used the WinSCP .NET assembly inside an SSIS Scripting Task, as this is what WinSCP also recommends as the way to achieve SFTP using WinSCP in SSIS.
See this guide - Using WinSCP .NET Assembly from SQL Server Integration Services (SSIS). It walks you through the install and setup and also contains working sample code (after you change the script to your needs of course!).
Sample code - after you reference the WinSCPnet.dll assembly - is below.
using System;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.ScriptTask;
using System.AddIn;
using WinSCP;
namespace ST_5a30686e70c04c5a8a93729fd90b8c79.csproj
{
[AddIn("ScriptMain", Version = "1.0", Publisher = "", Description = "")]
public partial class ScriptMain : VSTARTScriptObjectModelBase
{
public void Main()
{
// Setup session options
SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Sftp,
// To setup these variables, go to SSIS > Variables.
// To make them accessible from the script task, in the context menu of the task,
// choose Edit. On the Script task editor on Script page, select ReadOnlyVariables,
// and tick the below properties.
HostName = (string) Dts.Variables["User::HostName"].Value,
UserName = (string) Dts.Variables["User::UserName"].Value,
Password = (string) Dts.Variables["User::Password"].Value,
SshHostKeyFingerprint = (string) Dts.Variables["User::SshHostKeyFingerprint"].Value
};
try
{
using (Session session = new Session())
{
// As WinSCP .NET assembly has to be stored in GAC to be used with SSIS,
// you need to set path to WinSCP.exe explicitly, if using non-default location.
session.ExecutablePath = #"C:\winscp\winscp.exe";
// Connect
session.Open(sessionOptions);
// Upload files
TransferOptions transferOptions = new TransferOptions();
transferOptions.TransferMode = TransferMode.Binary;
TransferOperationResult transferResult;
transferResult = session.PutFiles(#"d:\toupload\*", "/home/user/", false, transferOptions);
// Throw on any error
transferResult.Check();
// Print results
bool fireAgain = false;
foreach (TransferEventArgs transfer in transferResult.Transfers)
{
Dts.Events.FireInformation(0, null,
string.Format("Upload of {0} succeeded", transfer.FileName),
null, 0, ref fireAgain);
}
}
Dts.TaskResult = (int)DTSExecResult.Success;
}
catch (Exception e)
{
Dts.Events.FireError(0, null,
string.Format("Error when using WinSCP to upload files: {0}", e),
null, 0);
Dts.TaskResult = (int)DTSExecResult.Failure;
}
}
}
}
Install WinSCP and then create a folder where you want a file from client or put the file.Then Open a Execute Process Task and then go to Expression tab and set the Executable and Arguments with below codes(Please change accordingly).
Write this code in notepad and save as winscp.txt at the path C:\path\to\winscp.txt.
Open sftp://Host_Name:Password#apacsftp01.mftservice.com/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
get -delete /home/client/Share/MediaData/Media_file.xlsx
exit
