Internet & LAN Over VPN Using OpenVPN – Linux Server – Windows/Linux Clients – Works For Gaming & Through Firewalls

The aim of this tutorial is to enable you to set up a little VPN that will let you do many things – but my primary goal when trying to get this to work was to allow me and my friend (who sits behind a firewalled network at University) to play the new games that would not work over Hamachi because they did not ship with LAN and required an always-on internet connection (DRM). His network also uses traffic shaping and blocks UDP packets, making online gaming impossible.

How To Set Up A Web-Based Enterprise Password Manager Protected By Two-Factor Authentication

While it is great that more services such as Facebook and Google are offering two-factor authentication, there are still plenty of services that do not. What is the next best thing? Using a password manager and incredibly complex passwords. A password manager allows you to use different passwords at all the sites and services you visit, but it creates a 'keys-to-the-kingdom' problem. This tutorial will show you how to install the WebKeePass open-source web-based, enterprise password manager and how to protect it with two-factor authentication from WiKID Systems. Note that we have not evaluated the security of WebKeePass - this would certainly be worthwhile. Our primary selection criteria were: open-source, multi-user and allowed for external authentication, in this case via LDAP. Another option that looked promising was CorporateVault.

Using Google Translate From The Command Line

Using Google Translate From The Command Line

I have found an article in one of the most famous Linux Arabic forums, it describes how to use Google Translate from the command line. It is a good script but it is needed to write the language pairs every time and I used to make the computers work for me not to work for computers, so I didn't like to do that write every time I want to use the script, usually I translate from English to Arabic, sometimes from Arabic to English and fewer times form some other languages to Arabic or to English if I found the direct translation from that language to Arabic is not clear enough. I have edited the script so now it checks the command arguments number.
