How To Configure Apache To Use Radius For Two-Factor Authentication On Ubuntu 12.04

This document describes how to add WiKID two-factor authentication to Apache 2.2.22 using mod_auth_radius on Ubuntu 12.04. It is also 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.

Creating An NFS-Like Standalone Storage Server With GlusterFS 3.0.x On Debian Squeeze

This tutorial shows how to set up a standalone storage server on Debian Squeeze. Instead of NFS, I will use GlusterFS
here. The client system will be able to access the storage as if it was
a local filesystem. GlusterFS is a clustered file-system capable of scaling to several
peta-bytes. It aggregates various storage bricks over Infiniband RDMA or
TCP/IP interconnect into one large parallel network file system.
Storage bricks can be made of any commodity hardware such as x86_64
servers with SATA-II RAID and Infiniband HBA.

How To Back Up MySQL Databases With mylvmbackup On Debian Squeeze

mylvmbackup
is a Perl script for quickly creating MySQL backups. It uses LVM's
snapshot feature to do so. To perform a backup, mylvmbackup obtains a
read lock on all tables and flushes all server caches to disk, creates a
snapshot of the volume containing the MySQL data directory, and unlocks
the tables again. This article shows how to use it on a Debian Squeeze
server.

All popular browsers offer build-in user agent switchers, so you can change your user agent without installing any extensions. Google Chrome and Internet Explorer both include user agent switchers in their developer tools, while Firefox offers an about:config option.

Websites identify browsers by their user agents. Modify a browser’s user agent and it will appear as a different browser – or even a browser running on another device, such as a smartphone or tablet.

Encrypt Your Data With EncFS (Debian Squeeze/Ubuntu 11.10)

EncFS
provides an encrypted filesystem in user-space. It runs without any
special permissions and uses the FUSE library and Linux kernel module to
provide the filesystem interface. It is a pass-through filesystem, not
an encrypted block device, which means it is created on top of an
existing filesystem. This tutorial shows how you can use EncFS on Debian
Squeeze/Ubuntu 11.10 to encrypt your data.
