# Joins Linux systems to Active Directory domains in a single step from the command line or from a GUI # Authenticates users with a single user name and password on both Windows and Linux systems # Enforces the same password policies for Linux users as for Windows users # Support for multiple forests with one-way and two-way cross forest trusts # Single sign-on for SSH and Putty # Single UID automatically assigned # Credential caching in the event of temporary loss of connectivity to the Active Directory Domain Controller # No Active Directory schema changes involved # Most recent Linux distributions supported

This is a quick tutorial on how to setup your Linux environment and VirtualBox, so that it can automatically create network interfaces and put them in bridge when the VM is launched.

Des scripts et des conseils pour cloner un système linux. Peut-être plus très à jour depuis la multiplication des liveCD, mais tout de même.

WEP was intended to provide comparable confidentiality to a traditional wired network (in particular it does not protect users of the network from each other), hence the name. Several serious weaknesses were identified by cryptanalysts — any WEP key can be cracked with readily available software in two minutes or less — and WEP was superseded by Wi-Fi Protected Access (WPA) in 2003, and then by the full IEEE 802.11i standard (also known as WPA2) in 2004. Despite the weaknesses, WEP provides a level of security that can deter casual snooping

Have fun with iptables, squid and mogrify!

This document describes how to set up Amanda (The Advanced Maryland Automatic Network Disk Archiver) on Debian Etch. For this tutorial I chose Ubuntu v7.04 as a backup-client. The resulting system provides a flexible backup-system with many features. It will be able to back up multiple hosts via network to various devices. I chose the disk based backup for this howto.

This guide shows how to install and configure Smokeping on Debian Etch to monitor network latency. From the Smokeping web site: "SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm data-store and to draw pretty graphs, giving up to the minute information on the state of each network connection."

Setting Up An iSCSI Environment On Linux Nowadays, the iSCSI technology is quite popular in the storage world. This article shows an iSCSI demo environment which consists of one Debian Linux host and one Netapp Filer.We try to show the most important features of this protocol. 1. What is iSCSI? It is a network storage protocol above TCP/IP. This protocol encapsulates SCSI data into TCP packets. iSCSI allows us to connect a host to a storage array via a simple Ethernet connection (tape drive). This solution is cheaper than the Fibre Channel SAN (Fibre channel HBAs and switches are expensive). From the host view the user sees the storage array LUNs like a local disks. iSCSI devices should not be confused with the NAS devices (for example NFS). The most important difference is that NFS volumes can be accessed by multiple hosts, but one iSCSI volume can by accessed by one host. It is similar to SCSIi protocol: usually only one host has access to one SCSI disk (the difference is the cluster enviroment). The iSCSI protocol is defined in the RFC3720 document by the IETF (Internet Engineering Task Force).

In this article I will show how to install and configure fail2ban on a Debian Etch system. Fail2ban is a tool that observes login attempts to various services, e.g. SSH, FTP, SMTP, Apache, etc., and if it finds failed login attempts again and again from the same IP address or host, fail2ban stops further login attempts from that IP address/host by blocking it with an iptables firewall rule.

SystemImager is software which automates Linux installs, software distribution, and production deployment. SystemImager is a part of System Installation Suite. SystemImager makes it easy to do automated installs (clones), software distribution, content or data distribution, configuration changes, and operating system updates to your network of Linux machines. You can even update from one Linux release version to another! It can also be used to ensure safe production deployments. By saving your current production image before updating to your new production image, you have a highly reliable contingency mechanism. If the new production enviroment is found to be flawed, simply roll-back to the last production image with a simple update command!
