Network Monitor Experts are tools that can be run directly from the Network Monitor Application. They provide external analysis of live or previously captured network traffic. These experts can help troubleshoot specific problems or provide more information to help you narrow down an issue. The following site has a list of the currently available experts and is where you are directed when you select "Download Experts" from the Expert Menu in the Network Monitor application. There you'll also find an SDK which contains a sample and further documentation to help you create your own experts. The Network Monitor installation provides the Help file which explains the Network Monitor API and includes some sample programs to help you learn. Network Monitor Experts on CodePlex The Network Monitor Parsers are constantly evolving and being updated based on changes to documentation and bug fixes.
John the Ripper password cracker John the Ripper is free and Open Source software, distributed primarily in source code form. If you would rather use a commercial product tailored for your specific operating system, please consider John the Ripper Pro, which is distributed primarily in the form of "native" packages for the target operating systems and in general is meant to be easier to install and use while delivering optimal performance. This version integrates lots of contributed patches adding GPU support (OpenCL and CUDA), support for a hundred of additional hash and cipher types (including popular ones such as NTLM, raw MD5, etc., and even things such as encrypted OpenSSH private keys, ZIP and RAR archives, PDF files, etc.), as well as some optimizations and features. Unfortunately, its overall quality is lower than the official version's. Requires OpenSSL. There are unofficial binary builds (by John the Ripper user community members) for Windows, Linux, Solaris, and Mac OS X.
Net-SNMP FreeSWITCH | Communication Consolidation Techniques de scan de ports -sS(Scan TCP SYN) Le scan SYN est celui par défaut et le plus populaire pour de bonnes raisons. Il peut être exécuté rapidement et scanner des milliers de ports par seconde sur un réseau rapide lorsqu'il n'est pas entravé par des pare-feux. Le scan SYN est relativement discret et furtif, vu qu'il ne termine jamais les connexions TCP. Il marche également contre toute pile respectant TCP, au lieu de dépendre des particularités environnementales spécifiques comme les scans Fin/Null/Xmas, Maimon ou Idle le sont. Il permet de plus une différentiation fiable entre les états ouvert, fermé et filtré. Cette technique est souvent appelée le scan demi-ouvert (half-open scanning), car il n'établi pas pleinement la connexion TCP. -sT(Scan TCP connect()) Le scan TCP connect() est le type de scan par défaut quand le SYN n'est pas utilisable. Si le scan SYN est disponible, il vaut mieux l'utiliser. -sU(Scan UDP) Le scan UDP est activé avec l'option-sU. -sN; -sF; -sX (Scans TCP Null, FIN et Xmas)
Scanning the Internet with Nmap (Defcon 16) Tutorial Scanning The Internet With Nmap (Defcon 16) Description: How would you like to scan millions of hosts on the Internet and catalog all the interesting insights? This is exactly what Fyodor, the author of Nmap or Network Mapper did last summer. Thankfully, he then went on to share his finding with the community at Defcon 16 in his talk titled "Nmap: Scanning the Internet". Interestingly, as Fyodor notes in his talk that scanning such a large set of IP addresses did help him in uncovering many bugs in Nmap and also forced him to make enhancements and add new features to make the scanner really fast. The slides for the presentation are available here and a high resolution video can be downloaded here. Disclaimer: We are a infosec video aggregator and this video is linked from an external website.
