  • Ratuus – RATUUS is an easy to use, web based system for administration of POSTFIX virtual domains and users. Sounds good, but what does it really mean? Postfix mail server is able to work with non-system users, users which are not known to the operating system. This functionality is very useful since it gives you possibility to use one mail server for multiple domains without worrying that usernames will overlap. Like this you can have address [email protected] and also [email protected] and they can all point to different mailboxes. These kind of users are usually stored in some kind of a database, with MySQL database being most commonly used. And this is where RATUUS comes into play – it provides user friendly interface for managing these virtual users and domains. With RATUUS you can easily create, modify and delete domains, users and aliases and all your actions are immediately reflected to Postfix configuration. RATUUS is using the same database layout as famous PostfixAdmin so migration
  • Home · opensolutions/ViMbAdmin Wiki · GitHub – ViMbAdmin (pronounced vim-be-admin and meaning Virtual Mailbox Administration) is intended as an alternative to (and a near slot in replacement) for the popular but dated Postfix Admin application. It has been developed by Open Solutions, a company based in Dublin, Ireland specialising in PHP web application development, Linux and UNIX system administration and ISP grade networking and we are releasing it under a GPL V3 license. It is written in PHP using the Zend Framework, Doctrine ORM and Smarty with JQuery on the frontend.

  • Beleth – Security101 – Blackhat Techniques – Hacking Tutorials – Vulnerability Research – Security Tools – Beleth is a multi-threaded asynchronous SSH password auditing tool written in C. There are plenty of other password cracking programs out there that can do the job, but I wanted something small, fast, and custom as a proof of concept. After preliminary tests, Beleth was able to outperform both THC-Hydra and Ncrack. Beleth also allows you to run a remote command after successfully cracking a password.

  • How-To: Bash Parameter Expansion and String Manipulation | Debuntu – There is many ways to do string manipulation with bash, like finding a filename extension using expr, separating the directory part from a filename using dirname and basename…. or even more sophisticated ones based on regex, sed…. Why using a sledgehammer to crack a nut when you could use bash builtin functionalities! Bash built-ins expansion can be used to: Get substrings Substitute part of a string Case modification Removing prefix and suffix of a string
  • Vagrant – Create and configure lightweight, reproducible, and portable development environments. Vagrant is a tool for building complete development environments.

  • » Linuxaria – Everything about GNU/Linux and Open source How to log the correct Ip having Varnish and Nginx – When you run a webserver behind a reverse proxy or HTTP accelerator such as Varnish, the webserver access logs will display the IP of the proxy (generally 127.0.0.1) instead of the end user’s IP. This is a problem when you have a software like webalizer, awstats or similar log file analysis program, because you lose one of the most important information: “Who is the requestor of a page ?”, also having all the access coming from the same IP (127.0.0.1) you lose information such as “what’s the browsing pattern of visitors ?” “Is someone trying to do something Nasty ?”

  • Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work. Below some steps use by me to make Squid 3.0 Stable1 and Squid 2.6 Stable17 authenticate against Active Directory (Windows 2003 Directory Service) and also to make it make the authorization using Ldap. This setup was not used in production environment yet, so its possible to had some problems not seen by me or scalabilities issues.
  • active directory – Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP – Server Fault – This is setup with Squid 3.0, has also been tested with Squid 3.1 and should work with Squid 2.7. Your Windows user must be a member of the SQUID_USERS group in Active Directory (for this case anyway).

    On the Windows side, Windows XP and Windows 2007 have been tested against Windows 2008, and Windows XP against Windows 2003.

  • Open vSwitch – What is Open vSwitch?

    Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, RSPAN, ERSPAN, CLI, LACP, 802.1ag). In addition, it is designed to support distribution across multiple physical servers similar to VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V.

  • Manuale Android – Androidpedia – AndroidWorld Wiki – Questo è un manuale all'utilizzo di Android. La versione "spiegata" in questo manuale è quella Vanilla ovvero quella pura di Android presente solo su alcuni terminali. Le case poi personalizzano i terminali con varie interfacce (vedi Sense) e quindi a volte stravolgono in parte l'esperienza di Android. Spesso comunque è possibile ricondursi a questo manuale per capire meglio il funzionamento di Android.
  • Marionnet.org – Home – Marionnet is a virtual network laboratory: it allows users to define, configure and run complex computer networks without any need for physical setup. Only a single, possibly even non-networked GNU/Linux host machine is required to simulate a whole Ethernet network complete with computers, routers, hubs, switchs, cables, and more.<br />
    Support is also provided for integrating the virtual network with the physical host network.<br />
    <br />
    As Marionnet is meant to be used also by inexperienced people, it features a very intuitive graphical user interface. Marionnet is written in the mostly functional language OCaml with just some little bits of C, and depends on User Mode Linux and VDE for the simulation part.<br />

  • Troubleshoot Connections through the PIX and ASA – Cisco Systems – This document provides troubleshooting ideas and suggestions for when you use the Cisco ASA 5500 Series Adaptive Security Appliance (ASA) and the Cisco PIX 500 Series Security Appliance. More often than not, when applications or network sources break or are not available, firewalls (PIX or ASA) tend to be a primary target and blamed as the cause of outages. With some testing on the ASA or PIX, an administrator can determine whether or not the ASA/PIX causes the problem.

  • ASCII Paint – Enjoy drawing and viewing some crazy ascii art. Output can be in C/C++/Java style comments Assembly comments, or the million other languages that support the # – sign comments.

    Use the buttons to change what your cursor does. Hit whatever key on the keyboard you want to be drawing with.

    If you make something cool, share it! It will be added to our database of ascii art, which will become much more accessible as time goes on. Right now you can only see random Ascii Art, but there will be a voting system shortly.

  • Scapy – Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f, etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining technics (VLAN hopping+ARP cache poisoning, VOIP decoding on WEP encrypted channel, …), etc.

This is a large undertaking and hopefully by opening the software we can elicit multiple contributors and contributions.
