Loop-AES

Post date: January 25, 2006, 23:01 Category: Security Views: 3342 Comments
Tutorial quote: This is a step by step tutorial on creating an encrypted partition using Loop-AES (using AES-256). This tutorial is known to work under sarge.

Loop-AES is more secure than dm-crypt (and possibly faster), although it requires a custom kernel module and is more work to install than dm-crypt.

Have a Bash With This Linux Shell

Post date: April 15, 2005, 05:04 Category: Programming Views: 3126 Comments
Tutorial quote: Any Linux administrator who wishes to remain sane relies heavily on scripting to automate routine tasks, customize jobs, and build the plumbing that connects the different utilities that make a Linux system run smoothly. The Linux world is chock-full of scripting languages: Perl, Python, PHP, Scheme, Tcl, Tk, Ruby, Forth, Smalltalk, Eiffel, and doubtless many more. To get the column started, we'll look at shell scripting with Bash, and scripting with Python and Perl.

CLI Magic: OpenSSH + Bash

Post date: January 25, 2006, 20:01 Category: Network Views: 2972 Comments
Tutorial quote: As a system administrator, I have used OpenSSH's piping abilities more times than I can remember. The typical ssh call gets me access to systems for administration with a proven identity, but ssh is capable of so much more. In combination with bash's subshell invocation, OpenSSH can distribute the heavy work, reduce trace interference on a system under test, and make other "impossible" tasks possible. I've even used it to make Microsoft Windows remote administration easier.

In the examples below, I have tried to avoid GNU-specific idioms for tools which have non-GNU counterparts. This practice improves portability of shell scripts in heterogeneous environments.
