Using mod_spdy With Apache2 On Debian Squeeze

Using mod_spdy With Apache2 On Debian Squeeze

SPDY (pronounced “SPeeDY”) is a new networking protocol whose goal
is to speed up the web. It is Google’s alternative to the HTTP protocol
and a candidate for HTTP/2.0. SPDY augments HTTP with several
speed-related features such as stream multiplexing and header compression. To use SPDY, you need a web
server and a browser (like Google Chrome and upcoming versions of
Firefox) that both support SPDY. mod_spdy is an open-source Apache
module that adds support for the SPDY protocol to the Apache HTTPD
server. This tutorial explains how to use mod_spdy with Apache2 on
Debian Squeeze.

Remotely Unlock Fully Encrypted Debian Squeeze

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.

How To Simulate Network Devices Using SNMP Simulator

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)

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.
