Remotely Unlock Fully Encrypted Debian Squeeze
In the past I have written several howtos for remotely unlocking fully encrypted Debian installations. With the advent of Debian Squeeze, the developers have integrated a simple way to do so. Most stuff is provided directly by Debian itself - meaning you don't need 3rd party scripts anymore. However it still involves a few steps which I describe below. Also I provide you with a bash script that will do all the steps automatically.
Linux Basics - Set A Static IP On Ubuntu
This tutorial explains how to set a static IP on an Ubuntu system from the command line.
Configuring DNSSEC On BIND9 (9.7.3) On Debian Squeeze/Ubuntu 11.10
This guide explains how you can configure DNSSEC on BIND9 (version 9.7.3 that comes with Debian Squeeze/Ubuntu 11.10) on Debian Squeeze and Ubuntu 11.10. It covers how to enable DNSSEC on authoritative nameservers (master and slave) and on resolving nameservers, creation of keys (KSKs and ZSKs), signing of zones, key rolling with rollerd, zone file checking with donuts, creation of trust anchors, using DLV (DNSSEC look-aside validation), and getting your DS records into the parent's zone.
How To Simulate Network Devices Using SNMP Simulator
This tutorial explains how you can simulate network devices for testing purposes with the free Verax SNMP Simulator. Verax SNMP agent simulator is a tool that can simulate multiple SNMPv1/v2c agents on a single host on standard 161 port through multi-netting. It allows IT personnel to build virtual, simulated networks of devices without purchasing any additional hardware, for instance for testing purposes. Individual simulated agent responses can be initially retrieved from existing devices and modified at runtime by user defined rules.
Using iSCSI On Debian Squeeze (Initiator And Target)
This guide explains how you can set up an iSCSI target and an iSCSI initiator (client), both running Debian Squeeze. The iSCSI protocol is a storage area network (SAN) protocol which allows iSCSI initiators to use storage devices on the (remote) iSCSI target using normal ethernet cabling. To the iSCSI initiator, the remote storage looks like a normal, locally-attached hard drive.
Web Filtering On Squid Proxy
This HOWTO describes how to protect your home / small enterprise network users from objectionable internet contents with help of HTTP proxy. Our goal is to set up a free Linux based server running Squid and deploy web filtering application on it saving bandwidth, speeding up web access and blocking obsessive and potentially illegal and malicious web files.
Distributed Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10
This tutorial shows how to combine four single storage servers (running Ubuntu 11.10) to one large storage server (distributed storage) with GlusterFS. The client system (Ubuntu 11.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.
OpenSUSE 12.1 Samba Standalone Server With tdbsam Backend
This tutorial explains the installation of a Samba fileserver on OpenSUSE 12.1 and how to configure it to share files over the SMB protocol as well as how to add users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access.
Virtualization With KVM On A CentOS 6.2 Server
This guide explains how you can install and use KVM for creating and running virtual machines on a CentOS 6.2 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.
Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support On CentOS 6.2
Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a CentOS 6.2 server with PHP5 support (through PHP-FPM) and MySQL support.
