We have talked about security in this space before, in more abstract terms. More specifically, we are going to review the basic setup and some simple access rules using the venerable and ever popular ‘iptables’ firewall available for every Linux distribution around.
Accessing your desktop remotely is a convenience that we all appreciate. Many people set up VNC Server and an associated client in order to have their full ‘X’ capable desktop with them wherever they have a network connection. What some do not realize is that VNC as a protocol is extremely insecure and very susceptible to MitM snooping (Man in the Middle) since much of the text back and forth between client and server is transmitted as clear text. Today we are going to install and configure a simple VNC Server, access it with a VNC client and then add some security by using it over SSH.
This article will deal with installation and configuration of WebDAV server on Ubuntu Linux. WebDAV stands for Web Distributed Authoring and Versioning and allows connected users the edit and share data online via the HTTP protocol. This makes WebDAV a popular choice for developers when combined, for example, with Subversion or OpenLink Virtuoso. WebDAV is supported by number of clients ranging from davfs2, which makes it possible to mount the WebDAV's data storage to include into the local filesystem. This can be done with the mount command to various GUI applications with the native WebDAV support such as Nautilus, konqueror, etc. Futhermore, in this guide we will combine WebDAV with the Apache2 server.
LEMP is an alternative to LAMP, the Linux based web server configuration stack using MySQL and PHP. However, instead of Apache LEMP is deployed with Nginx ( pronounced engine-x or en-juhn-eks ) web server. Nginx is a free, open-source, high-performance HTTP server and reverse proxy, which can be also used as a mail proxy. Nginx is acclaimed for having low memory usage and thus it is favored solution for a low RAM web server deployments such as VPS, etc. The difference in a memory consumption and serving speed between Apache and Nginx is likely to be noticeable under a heavy load. Thus, configuring Nginx should also help you to protect against sudden traffic spikes. However, the choice of using Ngnix over Apache is a matter of your environment where many aspects needs to be taken into the consideration. These are the content to be served, configuration settings, number of modules enabled, etc. In this tutorial we will setup a basic LEMP configuration on Ubuntu Linux.
Question2Answer (Q2A) is a popular open source Q&A solution, currently in use on thousands sites world-wide in 40 languages. It is built on the standard PHP/MySQL platform, and runs safe and fast. A Q&A engine helps you to create an online community to share knowledge.
People with questions quickly get the answers they need. The community dynamic is enriched by commenting, voting, notifications, user points and rankings.
In this guide we will show you how to install this popular software on LAMP ( Linux Apache MySQL PHP). Operating system used will be Ubuntu 12.04.1 LTS.
Do you feel that someone is attempting to access you server? To find out, you can deploy a honeypot within your system to help you ease your paranoia by either confirming or dismissing your initial believe. As an example you can start the Kippo SSH honeypot, which allows you to monitor brute-force attempts, collect up today exploits and malware. Kippo also automatically records hacker's shell session, which you can replay to explore various hacking techniques and later use this gathered knowledge to harden your production server. Another reason why to install a honeypot is to take away an attention from your production server. In this tutorial we will show how to deploy a Kippo SSH honeypot on the Ubuntu server.
