Ralentir le débit de postfix pour wanadoo/orange – Le blog de Michauko – Si vous avez un serveur d’envoi de mails (je ne parle pas d’être un spammeur) et beaucoup d’abonnés chez Wanadoo et Orange, vous risquez fort le rejet temporaire de votre serveur si le débit d’envoi est trop fort. C’est ce qui m’est arrivé et hop, 5000 mails entassés dans la file de postfix.
smtp-in.orange.fr refused to talk to me: postfix solution | floriancrouzat.net – Orange sadly limits inbound connexion to it’s MX to 1 connexion per IP, which is a total pain in the ass when you try to deliver newsletter, or manage a MTA. Here is a sample log from their MX: Jul 4 10:42:42 smtp.example.com postfix/smtp: 0123456789: host smtp-in.orange.fr[18.104.22.168] refused to talk to me: 421 mwinf5c34 ME Trop de connexions, veuillez verifier votre configuration. Too many connections, slow down. OFR004_104  However, since they won’t change anything, we have to take mesures, here’s what you can do if you run postfix: you have to set a per-destination concurrency limit.
Tmux: A Simple Start – In all likelihood, you’ve probably already heard of tmux. However, you may not be using it everyday. If tmux is on your “Someday” list because you think it is too complicated (I mean, c’mon, the word “multiplexer” is just plain scary), then I am here to show you just how easy it is to put tmux into your workflow.
Tyblog | Yet Another Vim Setup – Vim is an excellent text editor. I’ve used it for many years and like most vim users, have collected a fairly large collection of settings in my .vimrc and learned how to grok my vim usage effectively through a lot of trial and error. To that end, I’ve tried to assemble a useful overview of my experience with vim.

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 firstname.lastname@example.org and also email@example.com 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

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.

A Gentoo Linux Advanced Reference Architecture – The book "A Gentoo Linux Advanced Reference Architecture" is meant as a resource displaying the powerful features of many free software solutions that are supported on top of Gentoo Linux. It is a deep-dive approach in many aspects related to processes, supportability, maintainability based on Gentoo Linux system deployments. Unlike the existing, per-application documents that exist on the Internet (and which are a valuable resource to get into the gory details of many applications) and the per-distribution guides that provide information on using that particular distribution, this book will focus more on architecturing IT infrastructure for medium-sized enterprises. Smaller enterprises might find the reference architecture here too expensive or large – however, many services described in the book can be slimmed down into a smaller deployment as well.
