    Author: WebmaestroTags: , Comments: 4

    How To Test Your Dansguardian, Safesquid, POESIA, Parental Internet Filter Or We-Blocker Keyword Filter Anytime Anywhere Keyword filters block unwanted web pages on the basis of potentially fallen words found in them. However, to be sure that a page is indeed offensive, keyword filters nowadays are not designed to block sites on the basis of just about any potentially offensive word. Instead they measure the number of potentially offensive phrases and often the number of times they occur so as to allow a limited number of occurrences in pages such as those on anatomy, forms requiring gender information, crime reports, statistical reports, administrative information, art etc. The leading keyword blockers like Dansguardian which is extremely popular on Linux or SafeSquid which is popular on Linux and Windows use this method known as a weighed keyword score.

    ubuntu Author: nowenTags: , , , Comments: 0

    How To Add WiKID Two-Factor Authentication To OpenVPN Community On Ubuntu 13.04 These instructions describe setting up two-factor authentication with WiKID Strong Authentication, which is a commercial/open source two-factor authentication system and OpenVPN, an SSL-encrypted VPN, on an Ubuntu 13.04 Linux server using the Radius Pluggable Authentication Module. First, we will configure PAM to use Radius, then we will configure OpenVPN to use PAM and one-time passwords, then we will create a network client on the WiKID server for OpenVPN. We won't go into specifics about installing these services, rather we will focus on configuring them to all work together.

  • Setting Up A Subversion Repository On Linux

    Author: mscheringTags: Comments: 1

    Setting Up A Subversion Repository On Linux In this tutorial I'll explain how to setup a subversion repository for PHP Javascript development. The SVN repository will be used by multiple users using an SSH key to logon to the server. All users will use the svn system user but we'll use the SSH key to identify the user. A pre-commit hook will be used to validate the PHP and Javascript to comply with coding rules.

  • How To Configure Apache To Use Radius For WiKID Two-Factor Authentication On Ubuntu

    ubuntu Author: nowenTags: , , , , Comments: 0

    How To Configure Apache To Use Radius For WiKID Two-Factor Authentication On Ubuntu This document describes how to add WiKID two-factor authentication to Apache 2.x using mod_auth_radius on Ubuntu 12.04 Precise. It is recommended that you consider using mutual https authentication for web applications that are worthy of two-factor authentication. Strong mutual authentication means that the targeted website is authenticated to the user in some cryptographically secure manner, thwarting most man-in-the-middle attacks. The use of cryptography is key. While some sites use an image in an attempt to validate a server, it should be noted that any man-in-the-middle could simply replay such an image.

  • Increasing the security of PPTP by adding two-factor authentication to poptop

    Author: nowenTags: , Comments: 0

    Security Issues and Poptop PPTP does not have the best history in terms of security. The original Microsoft implementation for PPTP faired very poorly. MS-CHAPV2 solved these weaknesses - for wired networks. Unfortunately, back in 2004, Joshua Wright released a version of ASLEAP capable of brute-force attacking PPTP passwords in a wireless environment. As a systems administrator for the VPN, you can't tell if a user is connecting via some public WiFi service where someone might be running a tool like ASLEAP. Yet, the presense of PPTP client software on Windows machines makes using PPTP very tempting. The best answer to this problem is to utilize two-factor authentication. If a one-time passcode is brute-forced, it won't matter as it can't be used again.
