Link: How to spoof the MAC address of a network interface on Linux

A 48-bit MAC address (e.g., 08:4f:b5:05:56:a0) is a globally unique identifier associated with a physical network interface, which is assigned by a manufacturer of the corresponding network interface card. Higher 24 bits in a MAC address (also known as OUI or “Organizationally Unique Identifier”) uniquely identify the organization which has issued the MAC address, so that there is no conflict among all existing MAC addresses.

While a MAC address is a manufacturer-assigned hardware address, it can actually be modified by a user. This practice is often called “MAC address spoofing.” In this tutorial, I am going to show how to spoof the MAC address of a network interface on Linux.

Link: Browse Internet as Nobody knows what you are doing, Simple SOCKS Proxy setup under Linux

As you may know ISPs can see those links you visit from your devices while using their service, this thing bother me and many users who knows about this stuff. Simply we can use SOCKS proxy using SSH. This approach is useful to surf web because things will be encrypted and your local administrator or ISP won’t be able to see what you are doing, they just can see encrypted packets are floating. 🙂

Also this method won’t eat much of your bandwidth but a little difference you may notice while testing your bandwidth using speedtest tools.

Link: Some powerful options of Linux Dig command to Query DNS

What is dig

Dig is a short from Domain Information Groper. It perform DNS lookups and displays the answers that are returned from the name server(s) that were queried.This tool is an alternative DNS lookup tool, nslookup. Unless it is told to query a specific name server, dig will try each of the servers listed in /etc/resolv.conf

Link: OpenVPN on DD-WRT: A Secure Connection To Home Networks

Since the demise of the free LogMeIn service, you might have lost access to your home PC. Fortunately, with the right router, and a little bit of time, you can gain free access to your home machines very easily with OpenVPN. This guide I’ve written for the DSLReports.com community will focus primarily on OpenVPN running on DD-WRT, but should apply almost equally to “TomatoVPN” firmware, or newer Asus routers which include it (I would also recommend checking out “Tomato by Shibby” — as this looks to be some great firmware for those with supported hardware).

Link: Create Safe & Easy Shares Using Samba For Windows Machines

In the past I shared howto create samba share between Windows and Linux machines so both can read/write, and also shared a program called Nitroshare which allows to send/receive files between Linux/Mac/Windows without any complicated configurations. So this time I came up with another secure and easy method to share your data with network Windows machines (for specific users). If you are a beginner and not really familiar with Linux command line interface then Samba GUI can help you with this matter. So lets start…

Link: Features, Installation, Usage of Network Security Toolkit (NST) in Linux

There are so many Linux distribution in the world now. From general Linux category until specific purpose of Linux. Today we will see a sneak peak of Network Security Toolkit Linux.

What is Network Security Toolkit (NST) Linux

NST is a Linux distribution based on Fedora Linux. NST provides security toolkit for professionals and network administrator with a comprehensive set of Open Source Network Security Tools. All of the tools in Top 125 Network Security Tools are included inside NST Linux. NST also comes with an advanced Web User Interface (WUI). We can say that NST Control Panel is in a web form. Another important thing is that NST can be used as a network security analysis validation.

Link: How to use sshfs (Secure Shell FileSystem) to Mount Remote Directories Locally

Sshfs is a file system for operating systems that have FUSE (Filesystem in Userspace) implementation. Examples of such operating systems are Linux, Mac OS X and FreeBSD but not limited to these. SSHFS is a great tool as it enable a user to mount remote directories on the local machine securely. The SSH protocol encrypts the connection between the local and remote machine. This makes it difficult for a third party to see the files being exchanged between the two machines on the network.

Link: How to Turn Your Raspberry Pi into a File Server Using Samba

Back in the 1990s, Microsoft developed a protocol that allows one Windows machine to access the files and folders on another Windows machine. The protocol, which is known as the Common Internet File System (CIFS) – but was originally called Server Message Block (SMB), has been implemented on other operating systems including Linux. The most popular implementation is known as Samba and it allows devices like the Raspberry Pi to act as a CIFS file server. To put it another way, it allows a Windows PC to mount a folder on a Raspberry Pi and then copy, delete, read and write files on the it.

Installing and configuring Samba on a Raspberry Pi for basic file sharing is quite simple. …

Link: How To Set Up Unlocator DNS Under Linux To Access Netflix, Hulu, CBS, ABC, Pandora and More Outside The US

Tunlr, a free DNS service that allowed its users to access US-based on-demand Internet streaming providers from outside the US, was shut down recently.

For those who are looking for a reliable alternative, there’s Unlocator, a similar service that you can use to watch Netflix, Hulu, CBS, MTV, PBS, ABC, Pandora and more no matter where you live.

The service is free to use while in beta (I’m not sure when it will be out of beta) and once it leaves the beta, it will cost $4.95 / month.

At the time I’m writing this article, Unlocator supports 78 services, including: Netflix, Hulu, Pandora, ABC, AMC, BBC, CBS, Channel4, Discovery Channel, ESPN, Fox, HBO Go, MTV, NBC, PBS, Showtime, TV.com, VEVO, USA Network, VH1 and others. A complete list can be found HERE.

While Unlocator works as advertised, there is one issue: using the Unlocator DNS permanently is not a good idea for privacy/security reasons, speed and so on. For this reason, I’ve adapted the instructions for Tunlr I wrote a while back on WebUpd8, for Unlocator.
