Change python version system-wide

To change python version system-wide we can use update-alternatives command. Logged in as a root user, first list all available python alternatives:

# apt-get update
# apt-get install python3.6
# update-alternatives --list python
update-alternatives: error: no alternatives for python

The above error message means that no python alternatives has been recognized by update-alternatives command.

Configuring NETCONF

Example:

username admin privilege 15 secret admin
!
interface GigabitEthernet1
  ip address 10.10.0.240 255.255.240.0
  no shutdown

First, find out where pipenv has created your virtualenv setup and stashed the python executable you are using. From the command line in your project folder (where your Pipfile is), execute the following:

pipenv --py

This will give you the full path to your virtualenv python install. For my sample project it was:

VIRTUALENV_PYTHON_PATH_HERE=C:\Users\UmarDx\.virtualenvs\api-9dSW7b5h\Scripts\python.exe

Now, create a local settings file that VS Code will use for your project

Assume there are two servers 192.168.1.1 as the tester, and 172.16.8.1 as the target. We will test which open inbound ports on the target server.

PREROUTE all traffic from IP 192.168.1.1/32 to port 127.0.0.1:80

iptables -t nat -A PREROUTING -s 192.168.1.1/32 -p tcp -m tcp --dport 80 -j RETURN
iptables -t nat -A PREROUTING -s 192.168.1.1/32 -p tcp -j DNAT --to-destination :80

I have the some issue.

When I run the ee site create command I get this:

It’s VERY easy to setup your own VPN with docker. This guide assumes you’re ok with operating a linux box but know nothing about docker. I’ll break it down into easy steps:

Setup a docker host

Install docker on the host:

$ curl -sSL https://get.docker.com/ | sh

Run the docker image

Make directory for docker volume:

$ mkdir $HOME/openvpn-data

	#!/usr/local/env bash
	# Update system
	apt-get update && apt-get -y upgrade

	# Get build tools
	apt-get -y install build-essential wget curl

	# Define softether version
	RTM=$(curl http://www.softether-download.com/files/softether/ \| grep -o 'v[^"]*e' \| grep rtm \| tail -1)
	IFS='-' read -r -a RTMS <<< "${RTM}"

	#! /bin/sh
	### BEGIN INIT INFO
	# Provides: vpnclient
	# Required-Start: $all
	# Required-Stop: $network $local_fs $remote_fs $syslog
	# Default-Start: 2 3 4 5
	# Default-Stop: 0 1 6
	# Short-Description: Start VPN Client at boot time

	# This script will work on Debian, Ubuntu, CentOS and probably other distros
	# of the same families, although no support is offered for them. It isn't
	# bulletproof but it will probably work if you simply want to setup a VPN on
	# your Debian/Ubuntu/CentOS box. It has been designed to be as unobtrusive and
	# universal as possible.
