Performance Testing Suricata The Effect of Configuration Variables On Offline Suricata Performance A Project Completed for CS 6266 Under Jonathon T. Giffin, Assistant Professor, Georgia Institute of Technology by Winston H Messer Project Advisor: Matt Jonkman, President, Open Information Security Foundation December 2011 Messer ii Abstract The Suricata IDS/IPS engine, a viable alternative to Snort, has a multitude of potential configurations. A simplified automated testing system was devised for the purpose of performance testing Suricata in an offline environment. Of the available configuration variables, seventeen were analyzed independently by testing in fifty-six configurations. Of these, three variables were found to have a statistically significant effect on performance: Detect Engine Profile, Multi Pattern Algorithm, and CPU affinity. Acknowledgements In writing the final report on this endeavor, I would like to start by thanking four people who made this project possible: Matt Jonkman, President, Open Information Security Foundation: For allowing me the opportunity to carry out this project under his supervision. Victor Julien, Lead Programmer, Open Information Security Foundation and Anne-Fleur Koolstra, Documentation Specialist, Open Information Security Foundation: For their willingness to share their wisdom and experience of Suricata via email for the past four months. John M. Weathersby, Jr., Executive Director, Open Source Software Institute: For allowing me the use of Institute equipment for the creation of a suitable testing -
GNU Wget 1.10 the Non-Interactive Download Utility Updated for Wget 1.10, Apr 2005
GNU Wget 1.10 The non-interactive download utility Updated for Wget 1.10, Apr 2005 by Hrvoje Nikˇsi´cand the developers Copyright c 1996–2005, Free Software Foundation, Inc.

Chapter 1: Overview 1 1 Overview GNU Wget is a free utility for non-interactive download of files from the Web. It supports http, https, and ftp protocols, as well as retrieval through http proxies. This chapter is a partial overview of Wget’s features. • Wget is non-interactive, meaning that it can work in the background, while the user is not logged on. This allows you to start a retrieval and disconnect from the system, letting Wget finish the work. By contrast, most of the Web browsers require constant user’s presence, which can be a great hindrance when transferring a lot of data. • Wget can follow links in html and xhtml pages and create local versions of remote web sites, fully recreating the directory structure of the original site. This is sometimes referred to as “recursive downloading.” While doing that, Wget respects the Robot Exclusion Standard (‘/robots.txt’). Wget can be instructed to convert the links in downloaded html files to the local files for offline viewing. -
Toolchains Instructor: Prabal Dutta Date: October 2, 2012
EECS 373: Design of Microprocessor-Based Systems Fall 2012 Lecture 3: Toolchains Instructor: Prabal Dutta Date: October 2, 2012 Note: Unless otherwise specified, these notes assume: (i) an ARM Cortex-M3 processor operating in little endian mode; (ii) the ARM EABI application binary interface; and (iii) the GNU GCC toolchain. Toolchains A complete software toolchain includes programs to convert source code into binary machine code, link together separately assembled/compiled code modules, disassemble the binaries, and convert their formats. Binary program file (.bin) Assembly Object Executable files (.s) files (.o) image file objcopy ld (linker) as objdump (assembler) Memory layout Disassembled Linker code (.lst) script (.ld) Figure 0.1: Assembler Toolchain. A typical GNU (GNU's Not Unix) assembler toolchain includes several programs that interact as shown in Figure 0.1 and perform the following functions: • as is the assembler and it converts human-readable assembly language programs into binary machine language code. It typically takes as input .s assembly files and outputs .o object files. • ld is the linker and it is used to combine multiple object files by resolving their external symbol references and relocating their data sections, and outputting a single executable file. It typically takes as input .o object files and .ld linker scripts and outputs .out executable files. • objcopy is a translation utility that copies and converts the contents of an object file from one format (e.g. .out) another (e.g. .bin). • objdump is a disassembler but it can also display various other information about object files. It is often used to disassemble binary files (e.g. -

PORTING NEW CODE TO RISC-V WITH YOCTO/OPENEMBEDDED Martin Maas ([email protected]) 1st RISC-V Workshop, January 15, 2015 Monterey, CA WHY WE NEED A LINUX DISTRIBUTION • To build an application for RISC-V, you need to: – Download and build the RISC-V toolchain + Linux – Download, patch and build application + dependencies – Create an image and run it in QEMU or on hardware • Problems with this approach: – Error-prone: Easy to corrupt FS or get a step wrong – Reproducibility: Others can’t easily reuse your work – Rigidity: If a dependency changes, need to do it all over • We need a Linux distribution! – Automatic build process with dependency tracking – Ability to distribute binary packages and SDKs 2 RISCV-POKY: A PORT OF THE YOCTO PROJECT • We ported the Yocto Project – Official Linux Foundation Workgroup, supported by a large number of industry partners – Part I: Collection of hundreds of recipes (scripts that describe how to build packages for different platforms), shared with OpenEmbedded project – Part II: Bitbake, a parallel build system that takes recipes and fetches, patches, cross-compiles and produces packages (RPM/DEB), images, SDKs, etc. • Focus on build process and customizability 3 GETTING STARTED WITH RISCV-POKY • Let’s build a full Linux system including the GCC toolchain, Linux, QEMU + a large set of packages (including bash, ssh, python, perl, apt, wget,…) • Step I: Clone riscv-poky: git clone [email protected]:ucb-bar/riscv-poky.git • Step II: Set up the build system: source oe-init-build-env • Step III: Build an image (may -

Special thanks to Gilbert Ashley, the author of src2pkg, for his approval and support throughout this redesign. Thanks to Piete Sartain for adminstrating the src2pkg wiki and Drew Ames for the writing much of the great documentation on the src2pkg wiki. I would also like to thank Dr. Alexander Dekhtyar for acting as my advisor for my rst senior project idea. Abstract Package managers ease installation and removal of applications. How- ever, as the name indicates, in order for a package manager to be useful, they need packages created from upstream sources to manage. This is the purpose of src2pkg, a toolkit written in Bash shell script which automates many package creation tasks. src2pkg, however, suers from major de- sign aws that cripple its ability to package some exotic upstream sources. -
Replacing PGP 2.X with Gnupg
Replacing PGP 2.x with GnuPG This article is based on an earlier PGP 2.x/GnuPG compatability guide (http://www.toehold.com/~kyle/pgp- compat.html) written by Kyle Hasselbacher (<[email protected]>). Mike Ashley (<[email protected]>) edited and expanded it. Michael Fischer v. Mollard (<[email protected]>) transformed the HTML source to Doc- Book SGML and also expanded it further. Some of the details described here came from the gnupg-devel and gnupg-user mailing lists. The workaround for both signing with and encrypting to an RSA key were taken from Gero Treuner’s compatability script (http://muppet.faveve.uni-stuttgart.de/~gero/gpg-2comp/changes.html). Please direct questions, bug reports, or suggesstions to the maintainer, Mike Ashley.

Introduction This document describes how to communicate with people still using old versions of PGP 2.x GnuPG can be used as a nearly complete replacement for PGP 2.x. You may encrypt and decrypt PGP 2.x messages using imported old keys, but you cannot generate PGP 2.x keys. This document demonstrates how to extend the standard distribution of GnuPG to support PGP 2.x keys as well as what options must be used to ensure inter- operation with PGP 2.x users. -

Checkinstall
LinuxFocus article number 360 http://linuxfocus.org CheckInstall by Mario M. Knopf (homepage) About the author: Mario enjoys working with Linux, networks Abstract: and security related topics. Checkinstall is utility to automatically build RPM/Debian or Slackware packages from tar.gz source pages. This makes it possible to do a "clean" installation and de−installation of almost any source code tar.gz package. Translated to English _________________ _________________ _________________ by: Mario M. Knopf (homepage) Introduction It often happens that the program which one certainly would like to test, is only available as tar.gz source code (no rpm or Debian package available). In such a case, you download the source package, unpack it and compile it manually. So far, so good. However, what happens if you like to delete the program? The Makefile contains only in very few cases an appropriate routine to uninstall the program. Of course there is the possibility of installing the program into a temporary directory and write down all of the files which were created or modified by the installation for a later removing. But this procedure is painful and very extensive, if programs are frequently compiled from the sources. The tool CheckInstall [1] written by Felipe Eduardo Sánchez Díaz Durán solves this problem. As a rule, you compile and install a GNU Autoconf compliant program under use of the widely known command sequence ./configure && make && make install. The configure shell script attempts to guess correct values for various system−dependent variables, which are used later during the compilation. It checks whether all requirements for compilation are fulfilled and uses those values to create a Makefile in each directory of the package.
