Evolution of Unix and Unix-like systems






The ‘Unix philosophy’ originated with Ken Thompson's early meditations on how to design a small but capable operating system with a clean service interface. It grew as the Unix culture learned things about how to get maximum leverage out of Thompson's design. It absorbed lessons from many sources along the way.

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…

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:

Rbash - way to restrict what users can do on your Linux systems.

Rbash - limited shell
If Bash is started with the name rbash, or the --restricted or -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. A restricted shell behaves identically to bash with the exception that the following are disallowed or not performed:

Changing directories with the cd builtin.Setting or unsetting the values of the SHELL, PATH, ENV, or BASH_ENV variables.Specifying command names containing slashes.Specifying a filename containing a slash as an argument to the . builtin command.Specifying a filename containing a slash as an argument to the -p option to the hash builtin command.Importing function definitions from the shell environment at startup.Parsing the value of SHELLOPTS from the shell environment at startup.Redirecting output using the ‘>’, ‘>|’, ‘<>’, ‘>&’, ‘&>’, and ‘>>’ redirection operators.Using the exec builtin to replac…
