How To Set Up A Web-Based Enterprise Password Manager Protected By Two-Factor Authentication
Author: nowen • Tags: linux, security • Comments: 1How To Set Up A Web-Based Enterprise Password Manager Protected By Two-Factor Authentication While it is great that more services such as Facebook and Google are offering two-factor authentication, there are still plenty of services that do not. What is the next best thing? Using a password manager and incredibly complex passwords. A password manager allows you to use different passwords at all the sites and services you visit, but it creates a 'keys-to-the-kingdom' problem. This tutorial will show you how to install the WebKeePass open-source web-based, enterprise password manager and how to protect it with two-factor authentication from WiKID Systems. Note that we have not evaluated the security of WebKeePass - this would certainly be worthwhile. Our primary selection criteria were: open-source, multi-user and allowed for external authentication, in this case via LDAP. Another option that looked promising was CorporateVault.

Comments: 2 Enabling Compiz Fusion On An Ubuntu Classic 11.04 Desktop (GNOME) (NVIDIA GeForce 8200) This tutorial shows how you can enable Compiz Fusion on an Ubuntu 11.04 (Natty Narwhal) desktop with the classic GNOME interface, i.e., no Unity (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8200 here). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop.

Comments: 0 How To Set Up And Integrate An Ubuntu 10.04 LTSPv5 Server Into A Windows 2008 Active Directory Domain With the current economic conditions, companies have been trying to do more with less by recycling old hardware and utilizing open source software. That's also true where I work. Between our call center, finance, distribution, warehouse, and sales departments over 50% of the company's employees are running on RHEL4 LTSP thin clients. Recently it was decided to update our LTSP environment from RHEL4 to Ubuntu 10.04 with LTSPv5. Using the following steps, I was able to setup and integrate an Ubuntu 10.04 LTSPv5 server into a Windows 2008 Active Directory domain.

OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

Comments: 1 Enabling Compiz Fusion On An Ubuntu 11.04 Desktop (With The Unity Desktop) This tutorial shows how you can enable Compiz Fusion on an Ubuntu 11.04 (Natty Narwhal) desktop with the Unity interface (the system must have a 3D-capable graphics card which I assume it has because otherwise Unity wouldn't start, and GNOME would be used instead). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop.

How To Set Up A Postgresql 9.0 Hot Standby Streaming Replication Server With Repmgr On OpenSUSE 11.4
Author: wintel2006 •
Tags: suse, high-availability •
Comments: 4 How To Set Up A Postgresql 9.0 Hot Standby Streaming Replication Server With Repmgr On OpenSUSE 11.4 This is a tutorial how to set up a postgresql replicated hot standby server with streaming replication, and we also set up the repmgr to monitor and manage the replication cluster. Unlike most tutorials that copy the database file from master to slave (or standby) in the middle of running pg_start_backup() and pg_end_backup(), repmgr is used to simplify the whole procedure. (But I still think that procedure helps you a lot to understand how postgresql warm standby, pitr, and hot standby replication work.)

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Fedora 15 x86_64)
Author: Falko Timme •
Tags: email, fedora, postfix •
Comments: 2 Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Fedora 15 x86_64) This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.
