Just the other day I was looking for a good HowTo guide for SSH tunnelling in Linux but I could not exactly what I was looking for.  So once I found all the information I needed I thought I should write so someone - perhaps me - might find it useful in future. The basics - What exactly is SSH tunnelling SSH tunnelling allows you to encrypt data between two servers.  The data is transported via

Creating a daemon in Linux uses a specific set of rules in a given order. Knowing how they work will help you understand how daemons operate in userland Linux, but can operate with calls to the kernel also. In fact, a few daemons interface with kernel modules that work with hardware devices, such as external controller boards, printers,and PDAs. They are one of the fundamental building

IEEE Standard 754 floating point is the most common representation today for real numbers on computers, including Intel-based PC's, Macintoshes, and most Unix platforms. This article gives a brief overview of IEEE floating point and its representation. Discussion of arithmetic implementation may be found in the book mentioned at the bottom of this article. http://steve.hollasch.net/cgindex/

The standard library functions only have byte swapping functions for 16 bit and 32 bit integral types. 8 bit data doesn't need swapping. But sometimes you want to write floating point data to the network or a file. This is problematic in that different processor architectures may use different bit level representations of floating point data, but these days most machines use IEEE 754

Most programmers have heard or observed one strange thing or another about floating point numbers. For example, we often discover that floating point numbers that look the same do not necessarily satisfy C's "==" test. New programmers are usually taught never to use == for floating point numbers for this reason. Occasionally we run into other exceptional cases, for instance mathematically sound

A few weeks ago I was searching around the Internet for an explanation of how to write a macro (preprocessor) function that returns a value.  All I could find was various articles suggesting something like this: #define MAX(A,B) ((A > B) ? A : B) However, I was looking for a more complicated example for instance something with a loop like this: #define MAX(A,B) ((A > B) ? A : B) #define

This appendix explains how to transfer your Java programming skills to a substantial subset of C++. This is necessary for students who take their first programming course in Java and the second course in C++. Naturally, it would be easiest if the second course were also offered in Java, but learning to move from one language to another is a fact of life for today's

Shared libraries are libraries that are loaded by programs when they start. When a shared library is installed properly, all programs that start afterwards automatically use the new shared library. http://www.linux.org/docs/ldp/howto/Program-Library-HOWTO/shared-libraries.html

Static libraries are simply a collection of ordinary object files; conventionally, static libraries end with the ``.a'' suffix. This collection is created using the ar (archiver) program. Static libraries aren't used as often as they once were, because of the advantages of shared libraries (described below). Still, they're sometimes created, they existed first historically, and they're simpler to

Autotools are the set of GNU tools that configure their source packages for a particular computer system. If you have ever compiled a program using “configure” followed by “make” commands then chances are you have already used the output of Autotools. The purpose of these “configure” scripts is to create Makefiles and “config.h” files for your projects that point to libraries, define or undefine

Shared memory technology is a part of a powerful IPC (interprocess communication) toolbox in UNIX-derived systems, which allows arbitrary processes to exchange data and synchronize execution. There are many forms of IPC on a UNIX-derived system (Several forms of IPC in the base UNIX toolbox are serial communication mechanisms. These linear forms have many uses, but I’ll be focusing on shared

List of attributes that can be used improve gcc optimisations.  The ones I find most useful are: pure: Function doesn't change any external variables. const: Function doesn't read any external variables. noreturn: Function will not return e.g. exit() or abort(). nonnull: Warning if null arguments are passed. warn_unused_result: Warns if the result of a function is not used/checked. http://

Shared Memory is an efficeint means of passing data between programs. One program will create a memory portion which other processes (if permitted) can access. In the Solaris 2.x operating system, the most efficient way to implement shared memory applications is to rely on the mmap() function and on the system's native virtual memory facility. Solaris 2.x also supports System V shared memory,

"There is a widespread notion that the keyword volatile is good for multi-threaded programming. I've seen interfaces with volatile qualifiers justified as 'it might be used for multi-threaded programming'. I thought was useful until the last few weeks, when it finally dawned on me (or if you prefer, got through my thick head) that volatile is almost useless for multi-threaded programming.

In this tutorial, you'll learn the basics of using raw sockets in C, to insert any IP protocol based datagram into the network traffic. This is useful,for example, to build raw socket scanners like nmap, to spoof or to perform operations that need to send out raw sockets. Basically, you can send any packet at any time, whereas using the interface functions for your systems IP-stack (connect,

Caroline Cartwright, 48, of Washington, was dragged before magistrates back in April for five breaches of a noise abatement order requiring her to turn down the volume during intimate moments with hubby Steve. http://

Pownce isn’t the only site offering to share snippets of text with friends. Miniblogging sites let you write extremely short entries via the web and cellphones, and some let you share media too. We tested 9 of them: Jaiku, Twitter, Tumblr, Moodmill, Pownce, Hictu, Facebook’s status updates and the spin-offs from Bebo and Xanga. http://mashable.com/2007/07/03/pownce-rivals/

Miniblogging tools like Twitter are growing like mushrooms, but despite some strong newcomers in this space over the last few weeks, Twitter is still the leader when it comes to mobile. And although Twitter works great through SMS, there are a large number of mobile applications that let you save on SMS bills and get the best from Twitter on your phone: here are the 12 that stand out. http://

If you want to be sure that your email can be read by no one but you, then it needs to be encrypted. You'd be surprised to find out who might want to read your email. I was. One of the best encryption systems is called GPG encryption which is an open-source version of PGP encryption. PGP stand for Pretty Good Privacy and is actually an understatement made by a programmer who didn't want to be

Do you remember the good old days when mobile phones just worked? We're talking about 2006. In those days, Sony Ericsson made phones that did what it said on the tin. Then in 2007 most of the phones they made didn't work. Some, like the W580i, just fell to pieces when you opened the box. Others, like the W910i were absolutely brilliant until you switched them on. Then they switched themselves off

Squid is a high-performance proxy caching server for web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests.It

Petrol's octane rating is a measurement of the fuel's ability to resist engine knocking. Knock occurs when the fuel-air mix in the cylinder explodes instead of burning in a controlled way. This shockwave moves within the combustion chamber, and creates a metallic 'pinging' sound. An octane rating is often referred to as an 'anti-knock index'. If fuel has a high octane number, it will have a

In addition to the C-style casting operator (provided for backwards compatibility) the C++ standard defines four additional casting operators: static_cast const_cast dynamic_cast reinterpret_cast The purpose of these new casting operators is to provide better type checking. Their use is encouraged over the old C-style casting operator.http://www.cppreference.com/wiki/keywords/

This article describes the required steps to convert a portion of RAM into swap space. We examine some of the reasons you might want to do this, including that using RAM as swap can be many times less expensive than using most fast solid state storage solutions. Additionally, it can be a lot easier to purchase and implement. Read on for the details. http://kerneltrap.org/node/3660

Static linking is often required for security-related applications. For example, you may want to compile a statically-linked version of the "ls" program to go into your anonymous FTP directory. If you're doing computer forensics, you may want a toolkit of statically-linked executables that you can carry onto subverted systems (where you may not trust the shared libraries). Solaris has
