Definition of slackware

A Linux distribution that was derived from the Softlanding Linux System (SLS) by Patrick Volkerding in 1993. As a part-time project, the name was intended to convey a lack of serious commitment, although Slackware became popular with advanced Linux users who wanted to learn more about the system. More than a dozen Linux distributions evolved from Slackware, including Slackintosh, a version for PowerPC-based Macs (prior to Intel-based Macs). 

A full instalation of Slackware includes (among other features):

• the X Window System  
• C/C++ development environments 
• Perl
• networking utilities
• a mail server
• a news server
• a web server 
• an FTP server
• the GNU Image Manipulation Program

Slackware's name is a reference to the concept of "slack" in the Church of the SubGenius, a largely Internet-based satirical pseudoreligion that had a cult following in the 1980s-90s. Within the Church, along with the common meaning of latitude, slack also implies personal space and freedom, independence, and the capacity for original thought. The developers of the Slackware operating system used the term to suggest that the project was, at least at its inception, a not-quite-serious spin-off project.

How to Enable or Disable Ethernet at Mikrotik with Command Line Interface (CLI)

Today, my friend learn to me about "How to Enable or Disable Ethernet Interface at Mikrotik with Command Line Interface (CLI)". Here, I will share you about that.

Step by step will be done :

- Open "Command Prompt" in "Start Menu" --> run --> cmd --> enter

- Type "telnet" command with your Mikrotik IP Address--> enter

- Type your log in account, example : admin --> enter

- Type your password --> enter

- In "admin prompt", type "int" (interface) --> enter

- In "admin > interface", type "pr" (print) --> enter (to show all of Ethernet interface)

- Choose number of Ethernet Interface which your want to enable or disable. Here, I choose of Ethernet number 3

- In "admin > interface", type "dis 3" (disable Ethernet number 3) or "ena 3" (enable Ethernet number 3)

- In "admin > interface", type "pr" (print) --> enter (to show all of Ethernet interface). On screen display you will see of Ethernet number 3 will be done to disable.

- Finally, in "admin > interface", type "/quit" --> enter (to exit from telnet program)

Configuration

RouterOS supports various methods of configuration - local

access with keyboard and monitor, serial console with a

terminal application, Telnet and secure SSH access over

networks, a custom GUI configuration tool called Winbox,

a simple Web based configuration interface and an API

programming interface for building your own control

application. In case there is no local access, and there is

a problem with IP level communications, RouterOS also

supports a MAC level based connection with the custom

made Mac-Telnet and Winbox tools.

RouterOS features a powerful, yet easy to learn command-

line configuration interface with integrated scripting

capabilities.

  •     Winbox GUI over IP and MAC

  •     CLI with Telnet, SSH, Local console and Serial console

  •     API for programming your own tools

  •     Web interface

New in RouterOS v4 is the Lua scripting language, which

opens up a multitude of approaches in automation and

programming of your router.

Web - Server Types

Every Web site sits on a computer known as a Web server. This server is always connected to the internet. Every Web server that is connected to the Internet is given a unique address made up of a series of four numbers between 0 and 255 separated by periods.for example, 68.178.157.132 or 68.122.35.127.

When you register a Web address, also known as a domain name, such as tutorialspoint.com you have to specify the IP address of the Web server that will host the site. You can load up with Dedicated Servers that can support your web-based operations.

There are four leading web browsers: Apache, IIS, lighttpd and Jagsaw. Now we will see these servers in bit more detail.

Apart from these Web Servers, there are other Web Servers also available in the market but they are very expansive. Major ones are Netscape's iPlanet, Bea's Web Logic and IBM's Websphere.

Apache HTTP Server

 

This is the most popular web server in the world developed by the Apache Software Foundation. Apache web server is an open source software and can be installed on almost all operating systems including Linux, Unix, Windows, FreeBSD, Mac OS X and more. About 60% of the web server machines run the Apache Web Server.

You can have Apache with tomcat module  to have JSP and J2EE related support.

You can have detailed information about this server at Apache HTTP Server.

 Internet Information Services

The Internet Information Server (IIS) is a high performance Web Server from Microsoft. This web server runs on Windows NT/2000 and 2003 platforms ( and may be on upcoming new Windows version also). IIS comes bundled with Windows NT/2000 and 2003; Because IIS is tightly integrated with the operating system so it is relatively easy to administer it.

lighttpd

 

The ighttpd , pronounced lighty is also a free web server that is distributed with the FreeBSD operating system. This open source web server is fast, secure and consumes much less CPU power. Lighttpd can also run on Windows, Mac OS X, Linux and Solaris operating systems.

You can have detailed information about this server at lighttpd.

Sun Java System Web Server

This web server from Sun Microsystems is suited for medium and large web sites. Though the server is free it is not open source. It however, runs on Windows, Linux and Unix platforms. The Sun Java System web server supports various languages, scripts and technologies required for Web 2.0 such as JSP, Java Servlets, PHP, Perl, Python, Ruby on Rails, ASP and Coldfusion etc.You can have detailed information about this server at Sun Java System Web Server.

Jigsaw Server

Jigsaw (W3C's Server) comes from the World Wide Web Consortium. It is open source and free and can run on various platforms like Linux, Unix, Windows, Mac OS X Free BSD etc. Jigsaw has been written in Java and can run CGI scripts and PHP programs.
