Learn more about VPN, VPN types, VPN protocols and free VPN servers: https://com.puter.tips/search/label/VPN You can set up a PPTP server or an L2TP/IPsec connection on Android as shown in the previous articles or you can use a TOR enabled android app as described in this article. What is Tor? Tor is free software for enabling anonymous communication and an open network that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security. The name is derived from an acronym for the original software project name "The Onion Router". Tor on Android Tor is available for Android by installing our package named Orbot. Orbot is an application that allows mobile phone users to access the web, instant messaging and email without being monitored or blocked by their mobile internet service provider. Orbot brings the features and function...

Learn more about VPN and PPTP: https://com.puter.tips/2018/09/free-vpn-service-for-router.html OSI model layers The main concept of OSI is that the process of communication between two endpoints in a network can be divided into seven distinct groups of related functions, or layers. Each communicating user or program is on a device that can provide those seven layers of function. In this architecture, each layer serves the layer above it and, in turn, is served by the layer below it. So, in a given message between users, there will be a flow of data down through the layers in the source computer, across the network, and then up through the layers in the receiving computer. The seven layers of function are provided by a combination of applications, operating systems, network card device drivers and networking hardware that enable a system to transmit a signal over a network Ethernet or fiber optic cable or through Wi-Fi or other wireless protocols. Data Link (Layer 2)...

What is a Virtual Private Network (VPN)? A virtual private network extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Why have a VPN? A VPN, or virtual private network, is a secure tunnel between two or more devices. VPNs are used to protect private web traffic from snooping, interference, and censorship. Virtually anyone can benefit from VPN, whether it is to access content outside of your territory, protect your private information, or get access to cheap airfares. There are many attributes that must be considered when choosing a VPN as well; not all VPNs were created equal. There are two basic VPN types: 1. Remote Access VPN 2. Site – to – Site VPN Types of VPN protocols: The above two VPN types are based on different VPN security protocols. Each of these VPN protocols offers different features and le...

@echo off set "psCommand=powershell -Command "$pword = read-host 'Enter Password' -AsSecureString ; ^     $BSTR=[System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pword); ^         [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)"" for /f "usebackq delims=" %%p in (`%psCommand%`) do set password=%%p echo %password% This trick reads a password on Windows without echoing it to the screen by calling PowerShell from a batch file and using a SecureString prompt, so the typed characters do not appear in the console. Masking input is a small but useful courtesy in scripts that ask for credentials. Note that hiding the characters guards against shoulder surfing, not against the value being readable once it is in memory.
