What is ASP.NET core web hosting?

by Christina J.TrendingLeave a Comment on What is ASP.NET core web hosting?

The most concerning stuff to knowing about ASP.NET core web hosting is that it runs as a standalone, out-of-process Console utility. It’s not hosted inside of IIS and core doesn’t require IIS to run. ASP.NET Core programs have their personal self-hosted Web server and process requests internally the usage of this self-hosted server example.

You can run IIS as a front-end proxy server for ASP.NET Core programs due to the fact Kestrel is a raw Web server that doesn’t assist all features a full server like IIS supports. This is clearly a recommended exercise on Windows which will provide port eighty 80 or 443(secure port) forwarding which kestrel would not aid immediately. Windows IIS (or any other opposite proxy) will stay a crucial part of the server in spite of ASP.NET Core packages.

What is classic ASP.net?

In a Classic ASP.NET application, everything is hosted interior of an IIS Worker Process (w3wp.Exe) that is the IIS Application Pool. The Application Pool hosts your ASP.NET application and your software is instantiated by means of the built-in ASP.NET website hosting functions in IIS. The local runtime manager instantiates the .NET Runtime to your application’s behalf and brings up the HttpRuntime object that is then used to fireplace requests thru the ASP.NET software pipeline as requests come in from the native HTTP.Sys motive force. Requests are available from HTTP.Sys and are dispatched to the proper site that is mapped to the Application Pool and the HttpRuntime example hosted there.

How does work ASP.NET core with IIS?

ASP.NET Core packages are standalone Console applications invoked via the dotnet runtime command. They aren’t loaded into an IIS worker method however as a substitute loaded via a native IIS module referred to as AspNetCoreModule that executes the outside Console software.

The AspNetCoreModule is configured via the web.Config record discovered inside the web application’s root folder, which points a the startup command (dotnet) and argument (your utility’s primary .dll) which might be used to launch the .NET Core application.

How web.config looks like?
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <!--
    Configure your application settings in appsettings.json. Learn more at 
  -->
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*"
        modules="AspNetCoreModule" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="dotnet"
                arguments=".\AlbumViewerNetCore.dll" 
                stdoutLogEnabled="false" 
                stdoutLogFile=".\logs\stdout" 
                forwardWindowsAuthToken="false" />
  </system.webServer>
</configuration>

How to install .net core in Linux?

by Christina J.TrendingLeave a Comment on How to install .net core in Linux?

As we all know .NET core is cross-platform but it would be hard to publish a .NET core project on Linux OS. Do not worry, KLCWEB has a solution and guides to install .net core to Linux OS. Let’s install.net core in Linux OS.

1.) Install required component

  • sudo apt-get update
  • sudo apt-get install apt-transport-https
  • sudo apt-get update
  • sudo apt-get install dotnet-sdk-3.1
  • sudo apt-get install dotnet-runtime-3.1
  • sudo apt-get install aspnetcore-runtime-3.1

2.) Configure Apache server

Once You did install all the .NET core required components for Linux then, configure the Apache server to run the .NET core on Linux OS.

  • sudo apt-get install apache2
  • sudo a2enmod proxy proxy_http proxy_html proxy_wstunnel
  • sudo a2enmod rewrite
Now, you need to make configuration file for proxy on Apache

> sudo nano /etc/apache2/conf-enabled/netcore.conf

  1. VirtualHost *:80>  
  2.    ServerName www.DOMAIN.COM  
  3.    ProxyPreserveHost On  
  4.    ProxyPass / http://127.0.0.1:5000/  
  5.    ProxyPassReverse / http://127.0.0.1:5000/  
  6.    RewriteEngine on  
  7.    RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]  
  8.    RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]  
  9.    RewriteRule /(.*) ws://127.0.0.1:5000/$1 [P]  
  10.    ErrorLog /var/log/apache2/netcore-error.log  
  11.    CustomLog /var/log/apache2/netcore-access.log common  
  12. </VirtualHost>  

Paste this code to config file of Apache server, ensure that you will replace www.domain.com > your real domain name.

3.) Restart Apache server

  • sudo service apache2 restart
  • sudo apachectl configtest

4.) Start .NET service.

You need to move your all projects files to specific path using the below command.

sudo cp -a ~/release/ /var/netcore/

> Now, Create a service file for you .NET core project.

sudo nano /etc/systemd/system/ServiceFile.service

Now, restart your server using the below code.
  • sudo systemctl enable {Service Name}
  • sudo systemctl start {Service Name}

How many DNS servers? What are the DNS records?

by Christina J.TrendingLeave a Comment on How many DNS servers? What are the DNS records?

There are 4 types of DNS records for loading a web page. DNS recursor, Root nameserver, TLD nameserver, Authoritative nameserver.

1.) DNS recursor :

Typically the recursor is then responsible for making additional requests in order to satisfy the client’s DNS query. The DNS recursor is a server designed to receive queries from client machines through applications such as web browsers.

2.) Root nameserver :

The Root server is the first step in translating (resolving) human readable host names into IP addresses. which is most important things.

3.) TLD nameserver :

The top level domain server (TLD) is the next step in the search for a specific IP address, and it hosts the last portion of a hostname ( for example : for .com the TLD server is “com”.

4.) Authoritative nameserver :

The authoritative nameserver is the last stop in the nameserver query. If the authoritative nameserver has access to the requested record, it will return the IP address for the requested hostname back to the DNS recursor that made the initial request.

What are DNS records?

DNS servers create a DNS record to provide important information about a domain or hostname, particularly its current IP address. DNS records make a domain name such as ns1.com point to a web server’s IP address like 104.131.

 1.) A record :

A records are the most basic type of DNS record and are used to point a domain or subdomain to an IP address. Assigning a value to an A record is as simple as providing your DNS management panel with an IP address to where the domain or subdomain should point and a TTL.

2.) MX record :

Mail exchanger (MX) records are used to help route email according to the domain owner’s preference. The MX record itself specifies which server to attempt to use to deliver mail to when this type of request is made to the domain.

3.) CNAME record :

CNAME records are another commonly used type of DNS entry and are used to point a domain or subdomain to another hostname.

4.) SPF/TXT record :

An SPF record is a TXT record that is part of a domain’s DNS (Domain Name Service). An SPF record lists all authorized hostnames / IP addresses that are permitted to send an email on behalf of your domain.

What is the DNS (Domain Name System)?

by Christina J.Trending

DNS is the central part of the internet that provides a way to match names ( a destination website) to numbers (the address for the website).

The domain name system is the phonebook of the internet to access information online through domain names, for ex: klcweb.com. Web browsers interact through IP (internet protocol) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.

Each device connected to the internet has a unique IP address that other machines use to find the device. DNS servers eliminate the need for humans to memories IP addresses such as 192.168.1.2 (in ipv4).

How does DNS work?

The process of DNS resolution involves converting a hostname (such as www.example.com) into a computer-friendly IP address (such as 192.168.1.1). An IP address is given to each device on the Internet, and that address is necessary to find the appropriate Internet device – like a street address is used to find a particular home.

When a user wants to load a webpage, a translation must occur between what a user types into their web browser (klcweb.com) and the machine-friendly address necessary to locate the klcweb.blogspot.com webpage.

In order to understand the process behind the DNS resolution, it’s important to learn about the different hardware components a DNS query must pass between.

For the web browser, the DNS lookup occurs “ behind the scenes” and requires no interaction from the user’s computer apart from the initial request.
