HelenOS

HelenOS


HelenOS is a portable microkernel-based multiserver operating system designed and implemented from scratch. It decomposes key operating system functionality such as file systems, networking, device drivers and graphical user interface into a collection of fine-grained user space components that interact with each other via message passing. A failure or crash of one component does not directly harm others. HelenOS is therefore flexible, modular, extensible, fault tolerant and easy to understand.

We use newest available version to run: http://www.helenos.org/wiki/Download








Install Zabbix 3.4.1 on Oracle Linux 7.4 64-bit with Selinux enabled

Zabbix 3.4.1 on Oracle Linux 7.4 64-bit with Selinux enabled.
We will install Zabbix 3.4.1 on Oracle Linux 7.4 64-bit.

OS: Oracle Linux 7.4 64-bit
We install OS using VMware Workstation 12 Player. We use 20 GB partition with option automatic LVM.
After install make network interface start on boot
grep ONBOOT /etc/sysconfig/network-scripts/ifcfg-ens33 ONBOOT=yes
-set hostname:
hostnamectl set-hostname zabbix01 - do system update:
yum clean all; rm –fr /var/cache/yum; yum update –y Optional allow rule for ssh with firwall-cmd and install necessary packages: firewall-cmd --permanent --add-port=22/tcpyum install vim mc wget tcpdump -y
Finally after reboot we have newest possible kernel installed:
uname –aLinux zabbix01 4.1.12-103.3.8.el7uek.x86_64 #2 SMP Mon Aug 21 17:27:54 PDT 2017 x86_64 x86_64 x86_64 GNU/Linux
Next install your favorite X-System – for example:
yum groupinstall "X Window System" yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center l…

Visopsys

Visopsys  is an alternative operating system for PC compatible computers.  In development since 1997, this system is small, fast, and open source.  It features a simple but functional graphical interface, pre-emptive multitasking,  and virtual memory.

SkyOS

SkyOS (Sky Operating System) is a discontinued prototype commercial, proprietary,  graphical desktop operating system written for the x86computer architecture
We download SkyOS from http://www.skyos.org.
Then we make virtual machine using iso downloaded with 2GB RAM.







As a former open source project, SkyOS has been the subject of many debates involving free software.


Haiku

HAIKU
is an open source operating system currently in development. Specifically targeting personal computing, Haiku is a fast, efficient, simple to use, easy to learn, and yet very powerful system for computer users of all levels. Additionally, Haiku offers something over other open source platforms which is quite unique: The project consists of a single team writing everything from the kernel, drivers, userland services, tool kit, and graphics stack to the included desktop applications and preflets.

We use haiku-nightly-anyboot iso to prepare Virtual Machine.


After install reboot machine.






If You want to install some packages or update system just use pkgman :)

Redox

Redox is a Unix-like microkernel operating system written in the programming language Rust, a language with focus on safety and high performance.
Redox is inspired by previous kernels and operating systems, such as Minix or BSD.
The Redox OS Kernel is a hybrid kernel that supports X86_64 systems and provides Unix-like syscalls for primarily Rust applications.
The website can be found at https://www.redox-os.org.
After download iso file we can start Virtual Machine with Redox:
