I got the chance to configure one of the old system of my friend running Windows 2000 and Ubuntu 7, (yes it’s not typo) and he wants to authenticate some of his old Ubuntu PCs to Windows AD. Here’s the tutorial for adding Ubuntu box in a Active Directory domain and to authenticate the users with AD

Needed software:
Windows 2000 Advanced Server (function as Domain Controller, AD)
Linux (Ubuntu 6,7)
Winbind
Samba
krb-user
libpam-krb5

Used terms:
AD.freelinuxtutorials.com –> AD Domain
10.201.0.251 –> DC IP address
AD.freelinuxtutorials.com –> Kerberos Realm
10.201.0.193 –> NTP server











Installation of KVM and Eve-NG

 Kernel-based Virtual Machine or KVM is an open source virtualization solution that can make your Linux Server as hypervisor. I will demonstrate also how to install Virtual Machine (VM), for this example I will install Eve-NG (Emulated Virtual Environment) which is used by Network Engineers or Security and DevOps professionals to emulate different network devices/platforms such as Cisco,Juniper, Arista, Linux and so much more, mainly for POC, testing and learning.

Tested in CentOS 7
See first if your server supports Virtualization

# lscpu | grep Virt
Virtualization: VT-x

Unix, Linux, and variant history

Linux.org presented one of the most detailed important events in the history of the Linux operating system development

1983
September    Richard M. Stallman announces the GNU Project, an attempt at creating a completely free operating system.

1984
January    Work begins on the GNU operating system

1985
October    Free Software Foundation established as a non-profit organization to promote the development of Free Software. Sponsors the GNU Project.

1987
January    Computer science professor Andrew Tannenbaum publishes the textbook Operating Systems: Design and Implementation which includes a copy of a teaching version of Unix called Minix.
December    Larry Wall releases version 1.0 of Perl

Before we start with Linux tutorials, it’s better to understand its history to understand the philosophy behind and fully appreciate the best operating system in the planet.

Taken from Wikipedia:

In 1991, in Helsinki, Linus Torvalds began a project that later became the Linux kernel. It was initially a terminal emulator, which Torvalds used to access the large UNIX servers of the university. He wrote the program specifically for the hardware he was using and independent of an operating system because he wanted to use the functions of his new PC with an 80386 processor. Development was done on Minix using the GNU C compiler. This application is still the main choice for compiling Linux today (although the code can be built with other compilers, such as the Intel C Compiler).
