1. Mask the IP Address when the user enters in text field Java Swing. Ask Question Asked 6 years, 4 months ago. Active 3 years, 5 months ago. Viewed 7k times 1. I have a JTextField to accommodate an ip address with 3 dots. While entering ip address 255.255.123.122 in the textfield,these values are visible.
2. MacOS makes it very easy to find your IP address in the right settings. Step 1: Open System Preferences from the Dock — it’s the gear-based icon. Step 2: Select the globe-shaped Network icon.
3. Send texts using Messages on Mac. You can send messages with text, photos, and other files to your friends. If you’re using macOS Catalina or later, iOS 13 or later,.
4. An easy way to think of a local IP address is as the device’s network name—like Shane, Courtney, Anastasia, or Gub-Gub—only in this case, the name is represented by a string of numbers.
5. Mar 24, 2014  If you are using Ethernet, or on a Mac without wired networking built in, then you will see your IP address; if you are running a Mac that has both wired and wireless connections, then you will.

Open a command line and type the following command: ping -a IP, where -a is a command option that resolves addresses to hostnames (if it is possible). If you use hostnames with the ping command, a hostname is resolved to the IP address.

A dialog is a type of window that elicits a response from the user. Many dialogs—like the Print dialog, for example—let people provide several responses at once. Dialogs are presented in three ways: document-modal, app-modal, and modeless.

TIP An alert is a special type of dialog that provides important information about an error condition or warns the user about a potentially hazardous situation or consequence. For guidance, see Alerts.

Document-Modal Dialogs

A document-modal dialog is attached to a document as a sheet (see Sheets), and prevents the user from doing anything in the document until the dialog is dismissed. The user can still switch to other documents and apps. A Save dialog is an example of a document-modal dialog. See Save Dialogs.

App-Modal Dialogs

An app-modal dialog prevents the user from doing anything in the app until the dialog is dismissed. The user can still switch to other apps. An Open dialog is an example of an app-modal dialog. See Open Dialogs.

Modeless Dialogs

A modeless dialog is usually referred to as a panel. The user can continue interacting with documents and apps uninterrupted. The standard Find dialog is an example of a modeless dialog. See Find Dialogs and Panels.

Data Entry

Dialogs are intended to be small, transient windows that don’t require in-depth user interaction, so it’s important to ensure that data entry is efficient.

Provide default values for controls and fields whenever possible. It’s easier for a user to verify information than enter it from scratch.

Set the initial focus to the first location that accepts user input. Doing so lets the user begin entering data immediately, without needing to click a specific item like a text field or list.

Make static text selectable. For example, the user should be able to copy useful information, such as an error message, a serial number, or an IP address to paste elsewhere.

Check for errors during data entry. Instead of waiting and displaying an alert when the user tries to dismiss a dialog, check for errors during data entry so the user can fix the problem in context. Checking values immediately after their entry is best. Avoid validating after every keystroke, as too-frequent validation can slow down your app and be annoying.

Whenever possible, minimize the potential for invalid input. For example, use pop-up buttons to provide choices rather than asking the user to enter data, and use date pickers and number formatters to ensure that dates and numbers are entered correctly. For related guidance, see Pop-Up Buttons, Date Pickers, and Text Fields > Data Entry.

Consider including an Apply button that lets the user preview changes before committing to them. An Apply button makes sense in a modeless dialog for changes that can be applied, previewed, and undone quickly. Save dialogs and other dialogs that let users make changes that can’t be previewed easily should not include an Apply button.

Layout

Use a disclosure control to provide information or functionality that’s only occasionally needed. A disclosure control hides information or functionality, like advanced options, and reveals it only when the user clicks the control. For guidance, see Disclosure Controls.

Make sure interface elements scale properly when a dialog is resized. When a dialog permits resizing, elements that can scale with the dialog should do so accordingly. In general, views like boxes, tab views, and tables should expand to fill the dialog. In tables, existing columns should expand, and new columns and rows should be revealed as needed. Other elements that aren’t generally resized, like buttons, checkboxes, and segmented controls should remain the same size and be anchored to the sides (or the center) of the dialog.

Position buttons as expected. Any buttons in the bottom right of a dialog should dismiss the dialog. An action button, which initiates the dialog’s primary action, should be farthest to the right. A Cancel button should be to the immediate left of the action button. If a third dismissal button exists, it should be to the left of the Cancel button. A Help button should be farthest to the left. A button that affects the contents of the dialog itself, such as a button for expanding the dialog to reveal additional details, should be to the right of the Help button, or farthest to the left if no Help button is present.

Separate destructive buttons from nondestructive buttons. Destructive buttons, like Don’t Save, should be far enough away from safe buttons, like Save and Cancel, that the user has to make an intentional effort to click the button. If possible, allow at least 24 points of separation.

Dialog Dismissal

Provide a default button only when the user’s most likely action is harmless. Users sometimes press Return merely to dismiss a dialog, without reading its content, so it’s crucial that a default button initiate a harmless action. When there’s no default button, pressing Return should have no effect; the user should have to explicitly click a button to dismiss the dialog. Alternatively, when a dialog may result in a destructive action, Cancel can be set as the default button.

Provide a default button only when the Return key isn’t already used by text fields on the dialog. Having two behaviors for one key is confusing and makes the interface less predictable. The user might press Return one too many times and inadvertently activate the default button.

Include a Cancel button that responds to the standard cancellation keyboard shortcuts. A Cancel button provides a clear, safe way out of a dialog and returns the computer to the state it was in before the dialog appeared. Make sure the keyboard shortcut Command-period and the Esc (Escape) key are mapped to the Cancel button.

Make sure a Cancel button undoes all applied changes. A Cancel button should never silently commit changes the user previewed by clicking Apply.

Use Apply, OK, and Cancel buttons as intended. Clicking Apply previews changes but doesn’t dismiss the dialog. Clicking OK confirms the intent to accept any changes and dismisses the dialog. Clicking Cancel discards any applied changes and dismisses the dialog.

Ensure that dialog actions take place quickly. In general, the user should see near-immediate results after initiating an action from a dialog. For actions that take more than a couple seconds to complete, display progress information so the user knows the action has been initiated, how long it will take, and when its complete. For related guidance, see Progress Indicators.

Learn how to connect HDInsight to your on-premises network by using Azure Virtual Networks and a VPN gateway. This document provides planning information on:

• Using HDInsight in an Azure Virtual Network that connects to your on-premises network.
• Configuring DNS name resolution between the virtual network and your on-premises network.
• Configuring network security groups to restrict internet access to HDInsight.
• Ports provided by HDInsight on the virtual network.

Overview

To allow HDInsight and resources in the joined network to communicate by name, you must perform the following actions:

1. Create Azure Virtual Network.
2. Create a custom DNS server in the Azure Virtual Network.
3. Configure the virtual network to use the custom DNS server instead of the default Azure Recursive Resolver.
4. Configure forwarding between the custom DNS server and your on-premises DNS server.

These configurations enable the following behavior:

• Requests for fully qualified domain names that have the DNS suffix for the virtual network are forwarded to the custom DNS server. The custom DNS server then forwards these requests to the Azure Recursive Resolver, which returns the IP address.
• All other requests are forwarded to the on-premises DNS server. Even requests for public internet resources such as microsoft.com are forwarded to the on-premises DNS server for name resolution.

In the following diagram, green lines are requests for resources that end in the DNS suffix of the virtual network. Blue lines are requests for resources in the on-premises network or on the public internet.

Prerequisites

• An SSH client. For more information, see Connect to HDInsight (Apache Hadoop) using SSH.
• If using PowerShell, you'll need the AZ Module.
• If wanting to use Azure CLI and you haven't yet installed it, see Install the Azure CLI.

Create virtual network configuration

Use the following documents to learn how to create an Azure Virtual Network that is connected to your on-premises network:

Create custom DNS server

Important

You must create and configure the DNS server before installing HDInsight into the virtual network.

These steps use the Azure portal to create an Azure Virtual Machine. For other ways to create a virtual machine, see Create VM - Azure CLI and Create VM - Azure PowerShell. To create a Linux VM that uses the Bind DNS software, use the following steps:

1. Sign in to the Azure portal.

2. From the top menu, select + Create a resource.

3. Select Compute > Virtual machine to go to the Create a virtual machine page.

4. From the Basics tab, enter the following information:

   Field	Value
   Subscription	Select your appropriate subscription.
   Resource group	Select the resource group that contains the virtual network created earlier.
   Virtual machine name	Enter a friendly name that identifies this virtual machine. This example uses DNSProxy.
   Region	Select the same region as the virtual network created earlier. Not all VM sizes are available in all regions.
   Availability options	Select your desired level of availability. Azure offers a range of options for managing availability and resiliency for your applications. Architect your solution to use replicated VMs in Availability Zones or Availability Sets to protect your apps and data from datacenter outages and maintenance events. This example uses No infrastructure redundancy required.
   Image	Leave at Ubuntu Server 18.04 LTS.
   Authentication type	Password or SSH public key: The authentication method for the SSH account. We recommend using public keys, as they're more secure. This example uses Password. For more information, see the Create and use SSH keys for Linux VMs document.
   User name	Enter the administrator username for the VM. This example uses sshuser.
   Password or SSH public key	The available field is determined by your choice for Authentication type. Enter the appropriate value.
   Public inbound ports	Select Allow selected ports. Then select SSH (22) from the Select inbound ports drop-down list.

   Leave other entries at the default values and then select the Networking tab.

5. From the Networking tab, enter the following information:

   Field	Value
   Virtual network	Select the virtual network that you created earlier.
   Subnet	Select the default subnet for the virtual network that you created earlier. Do not select the subnet used by the VPN gateway.
   Public IP	Use the autopopulated value.

   Leave other entries at the default values and then select the Review + create.

6. From the Review + create tab, select Create to create the virtual machine.

Review IP Addresses

Once the virtual machine has been created, you'll receive a Deployment succeeded notification with a Go to resource button. Select Go to resource to go to your new virtual machine. From the default view for your new virtual machine, follow these steps to identify the associated IP Addresses:

1. From Settings, select Properties.

2. Note the values for PUBLIC IP ADDRESS/DNS NAME LABEL and PRIVATE IP ADDRESS for later use.

Install and configure Bind (DNS software)

1. Use SSH to connect to the public IP address of the virtual machine. Replace sshuser with the SSH user account you specified when creating the VM. The following example connects to a virtual machine at 40.68.254.142:

2. To install Bind, use the following commands from the SSH session:

3. To configure Bind to forward name resolution requests to your on premises DNS server, use the following text as the contents of the /etc/bind/named.conf.options file:

   Important

   Replace the values in the goodclients section with the IP address range of the virtual network and on-premises network. This section defines the addresses that this DNS server accepts requests from.

   Replace the 192.168.0.1 entry in the forwarders section with the IP address of your on-premises DNS server. This entry routes DNS requests to your on-premises DNS server for resolution.

   To edit this file, use the following command:

   To save the file, use Ctrl+X, Y, and then Enter.

4. From the SSH session, use the following command:

   This command returns a value similar to the following text:

   The icb0d0thtw0ebifqt0g1jycdxd.ex.internal.cloudapp.net text is the DNS suffix for this virtual network. Save this value, as it's used later.

5. To configure Bind to resolve DNS names for resources within the virtual network, use the following text as the contents of the /etc/bind/named.conf.local file:

   Important

   You must replace the icb0d0thtw0ebifqt0g1jycdxd.ex.internal.cloudapp.net with the DNS suffix you retrieved earlier.

   To edit this file, use the following command:

   To save the file, use Ctrl+X, Y, and then Enter.

6. To start Bind, use the following command:

7. To verify that bind can resolve the names of resources in your on-premises network, use the following commands:

   Important

   Replace dns.mynetwork.net with the fully qualified domain name (FQDN) of a resource in your on-premises network.

   Replace 10.0.0.4 with the internal IP address of your custom DNS server in the virtual network.

   The response appears similar to the following text:

Configure virtual network to use the custom DNS server

To configure the virtual network to use the custom DNS server instead of the Azure recursive resolver, use the following steps from the Azure portal:

1. From the left menu, navigate to All services > Networking > Virtual networks.

2. Select your virtual network from the list, which will open the default view for your virtual network.

3. From the default view, under Settings, select DNS servers.

4. Select Custom, and enter the PRIVATE IP ADDRESS of the custom DNS server.

5. Select Save.
   

Configure on-premises DNS server

In the previous section, you configured the custom DNS server to forward requests to the on-premises DNS server. Next, you must configure the on-premises DNS server to forward requests to the custom DNS server.

For specific steps on how to configure your DNS server, consult the documentation for your DNS server software. Look for the steps on how to configure a conditional forwarder.

A conditional forward only forwards requests for a specific DNS suffix. In this case, you must configure a forwarder for the DNS suffix of the virtual network. Requests for this suffix should be forwarded to the IP address of the custom DNS server.

The following text is an example of a conditional forwarder configuration for the Bind DNS software:

For information on using DNS on Windows Server 2016, see the Add-DnsServerConditionalForwarderZone documentation..

Once you've configured the on-premises DNS server, you can use nslookup from the on-premises network to verify that you can resolve names in the virtual network. The following example

This example uses the on-premises DNS server at 196.168.0.4 to resolve the name of the custom DNS server. Replace the IP address with the one for the on-premises DNS server. Replace the dnsproxy address with the fully qualified domain name of the custom DNS server.

Optional: Control network traffic

You can use network security groups (NSG) or user-defined routes (UDR) to control network traffic. NSGs allow you to filter inbound and outbound traffic, and allow or deny the traffic. UDRs allow you to control how traffic flows between resources in the virtual network, the internet, and the on-premises network.

Warning

HDInsight requires inbound access from specific IP addresses in the Azure cloud, and unrestricted outbound access. When using NSGs or UDRs to control traffic, you must perform the following steps:

1. Find the IP addresses for the location that contains your virtual network. For a list of required IPs by location, see Required IP addresses.

2. For the IP addresses identified in step 1, allow inbound traffic from that IP addresses.

   • If you're using NSG: Allow inbound traffic on port 443 for the IP addresses.
   • If you're using UDR: Set the Next Hop type of the route to Internet for the IP addresses.

For an example of using Azure PowerShell or the Azure CLI to create NSGs, see the Extend HDInsight with Azure Virtual Networks document.

Create the HDInsight cluster

Warning

You must configure the custom DNS server before installing HDInsight in the virtual network.

Use the steps in the Create an HDInsight cluster using the Azure portal document to create an HDInsight cluster.

Warning

• During cluster creation, you must choose the location that contains your virtual network.
• In the Advanced settings part of configuration, you must select the virtual network and subnet that you created earlier.

Connecting to HDInsight

Most documentation on HDInsight assumes that you have access to the cluster over the internet. For example, that you can connect to the cluster at https://CLUSTERNAME.azurehdinsight.net. This address uses the public gateway, which isn't available if you have used NSGs or UDRs to restrict access from the internet.

Some documentation also references headnodehost when connecting to the cluster from an SSH session. This address is only available from nodes within a cluster, and isn't usable on clients connected over the virtual network.

Torrent downloader for mac mojave. To directly connect to HDInsight through the virtual network, use the following steps:

1. To discover the internal fully qualified domain names of the HDInsight cluster nodes, use one of the following methods:

2. To determine the port that a service is available on, see the Ports used by Apache Hadoop services on HDInsight document.

   Important

   Some services hosted on the head nodes are only active on one node at a time. If you try accessing a service on one head node and it fails, switch to the other head node.

   For example, Apache Ambari is only active on one head node at a time. If you try accessing Ambari on one head node and it returns a 404 error, then it is running on the other head node.
