Do you have questions, comments, or suggestions? Liked this post? Creating and Using a self signed SSL Certificates in debian. This document covers a very specific, limited purpose, but one that meets a common need: preventing browser, mail, and other clients from complaining about the certificates installed on your server.
Not covered is dealing with a commercial root certificate authority (CA). Instead, we will become our own root CA, and sign our own certificates. (These procedures were developed using OpenSSL 0.9.6.) Quick Start Those who want to start creating certificates right away without reading this whole document should skip to the summary at the end. Note: a self-signed cert can be created with the simple command mod-ssl-makecert, part of the Debian package libapache-mod-ssl . Background Why be our own root CA? Prerequisites You will need an installed copy of OpenSSL for this, which is available from Chances are it is already installed on your machine.
Initial Setup First, we will create a directory where we can work. Creating a Root Certificate "Warning! Signing a Certificate Stunnel. PureMessage for UNIX: Configuring SMTP authentication with the M. Sophos recommends enabling the MTA-level IP Blocker as part of an overall strategy to optimize PureMessage performance.
If you want to authenticate connections using SMTP-AUTH while MTA-level blocking is enabled, you must modify PureMessage Postfix (SMTP-AUTH is not supported for external Postfix installations nor for any version of sendmail). When configured as described below, your system permits access for any IP address contained in the $mynetworks parameter, and then checks to see if it's an authenticated connection. If authentication is successful, messages are delivered without further testing. If authentication fails, messages are passed along to the MTA IP Blocker to begin testing.
Since SMTP-AUTH alone is not secure (it sends usernames and passwords over the internet in plain text format), it is recommended that you use SMTP-AUTH in conjunction with Transport Layer Security (TLS), so that this information is encrypted. What to do. Ubuntu Apache2 Virtual Server- Peter's Blog. Use SSH to Create Secure Tunnels for File Transfers (SFTP), Remo. This guide will show you how to access a computer located on your home network from outside of your local area network. For the purposes of this guide, let’s assume we are trying to access a HOME SERVER such as a Mac Mini located on your home WiFi router.
The home computer could just as easily be a Ubuntu, or similarly flavored Linux machine. The first thing that we will need to do is determine your home IP address, and then we will setup port forwarding on your wireless router. Keep reading to get started with this process or go here to learn how a SSH Tunnel works. The easiest way to determine your outside IP address is by visiting a site such as www.whatismyip.com. Write this number down but keep in mind that this number may change from time to time depending on your ISP. However, if you don’t turn off your cable or DSL modem, then your IP address shouldn’t change that often.

HOWTO undelete removed files and directories on an ext3 file sys. Carlo Wood, Mar 2008 Introduction It happens to everyone sooner or later: a split second after you hit Enter you realize your mistake, but it's too late; you just deleted a valuable file or directory for which no backup exists. Or maybe you have a backup, but it's a month old... and in shock you see the past month flash before your eyes as you realize in pain what you'll have to do all over again... Fortunately, you remember that files are never really deleted, at most overwritten by new content. So, you remount the disk read-only as fast as possible. But now? If you Google for "undelete ext3", almost every article you find will be users asking if it's possible and the answer is every time: no.
The most frequently quoted passage comes from the ext3 FAQ itself: Q: How can I recover (undelete) deleted files from my ext3 partition? Actually, you can't! Your only hope is to "grep" for parts of your files that have been deleted and hope for the best. However, this is not necessarily true. Groups. Searching for the QoS Holy Grail. With the convergence of voice, video and data in enterprise networks, and the increasing need to cut travel costs, both voice over IP and videoconferencing are becoming increasingly important. When coupled with the ever-present requirement that critical enterprise applications perform at their best, even in a fiscally tight environment, the days of "best effort" service are rapidly disappearing. Quality of service (QoS) is actually an ad hoc collection of technologies and techniques.
This ad hoc nature is what has created a barrier to true end-to-end strategy. Because application, operating system and networking vendors often differ on what set of QoS technologies they implement, it has been difficult for IT groups to implement QoS across their entire networks. Some say adding bandwidth is effective in providing QoS. For many companies, QoS appliances are the first step toward bringing QoS into the network where it is needed most - heavily congested WAN and Internet connections.

SQL Server 2005 Part 3 - High Availability and Scalability Enhan. In the previous article of this series, we started reviewing high availability and scalability enhancements in SQL Server 2005 (based on its recent Beta 2 release) by discussing database mirroring. In this article, we will continue exploring the same area of functionality, shifting our attention to failover clustering. We will also provide comparison of both features, which should help in recognizing the types of scenarios for which each of them is better suited.
Failover clustering has been supported since SQL Server 7.0 so it is not surprising that its latest implementation is a combination of already familiar (and stable) technology with a number of useful improvements. As before, the solution is based on Microsoft Cluster Services (MSCS), which, starting with Windows 2000 Server became an integral part of Advanced (or Enterprise, in case of Windows 2003 Server) and DataCenter editions. Scalability of clustered SQL Server is limited due to a couple of factors. File Synchronization with Unison. Unison is a file-synchronization tool that runs on Linux, UNIX and Microsoft Windows. Those of you who've used IBM Lotus Notes or Intellisync Mobile Suite probably have an idea of what synchronization is good for, as compared to one-way mirroring options such as rsync.
You might have mirrored a company document directory to your laptop, for example, and then modified a document or two. Other people might have modified other documents in the same directory by the time you get back. With rsync, you'd need to reconcile the differences between the two directories manually or risk overwriting someone's changes. Unison can sort out what has changed where, propagate the changed files and even merge different changes to the same file if you tell it how. Think of Unison as two-way rsync with a bit of revision control mixed in. Getting, Compiling and Installing Unison Unison's home page is maintained at the University of Pennsylvania; the project leader, Benjamin C. Configuring and Using Unison. Generating an SSL Certificate with Apache+mod_ssl. Introduction This document is intended to be a quick guide to generating and installing an SSL certificate on an Apache web server with the mod_ssl module.
While this is not an overly difficult process, it does involve running several long commands with numerous options. This document should be all that you need to walk you through the process of generating the certificate and installing it in your web server. This document does not attempt to discuss compiling or installing Apache and mod_ssl. For detailed instructions on that topic, please see "Building Apache with mod_ssl and Other Modules". This document also does not attempt to discuss detailed configuration of SSL hosts in Apache. Details will be provided on setting up a basic SSL virtual host that should work in nearly all standard circumstances.
Brief SSL Primer This section will serve as a very brief introduction to SSL, the Secure Socket Layer. Normal web traffic is sent unencrypted over the Internet. Network Overview /// Internet Traffic Report. Windows Server 2003 Server Clusters Quick Start Guide. This guide provides system requirements, installation instructions, and other, step-by-step instructions that you can use to deploy server clusters if you are using Microsoft® Windows Server™ 2003, Enterprise Edition, or Windows Server 2003, Datacenter Edition, operating systems.
The server cluster technology in Windows Server 2003, Enterprise Edition, and Windows Server 2003, Datacenter Edition, helps ensure that you have access to important server-based resources. You can use server cluster technology to create several cluster nodes that appear to users as one server. If one of the nodes in the cluster fails, another node begins to provide service. This is a process known as "failover. " In this way, server clusters can increase the availability of critical applications and resources.
