Quick UDP Internet Connections

What is QUIC?

QUIC (Quick UDP Internet Connections) is a new transport protocol for the internet, developed by Google.

QUIC solves a number of transport-layer and application-layer problems experienced by modern web applications, while requiring little or no change from application writers. QUIC is very similar to TCP+TLS+HTTP2, but implemented on top of UDP. Having QUIC as a self-contained protocol allows innovations which aren’t possible with existing protocols as they are hampered by legacy clients and middleboxes.

Key advantages of QUIC over TCP+TLS+HTTP2 include:
  • Connection establishment latency
  • Improved congestion control
  • Multiplexing without head-of-line blocking
  • Forward error correction
  • Connection migration

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…

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…


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.

After download iso file we can start Virtual Machine with Redox:
