Integrate Active Directory and OpenLDAP | Networking content from Windows IT Pro – OpenLDAP’s proxy service can allow LDAP operations to cross the boundaries between AD and OpenLDAP deployments. To demonstrate this proxy service, we walk through the steps to make AD’s cn=Users container, which by default contains all user objects, part of an OpenLDAP directory. To produce the examples in this article, I used CentOS 4.3, OpenLDAP 2.2.13, and AD running on Windows Server 2003 R2. Later in the article, I’ll show you a limitation in the commonly deployed OpenLDAP 2.2, which you can solve by installing OpenLDAP 2.3 on CentOS 4.3.
Let’s Chat — Self-hosted chat for small teams – WHAT IS THIS THING? Some backstory. Way back in 2012, we didn't like any of the existing chat services out there. So we decided to write our own. Let's Chat is a persistent messaging application that runs on Node.js and MongoDB. It's designed to be easily deployable and fits well with small, intimate teams. It's free (MIT licensed) and ships with killer features such as LDAP/Kerberos authentication, a REST-like API and XMPP support. Let's Chat is a side-project of the development team at Security Compass. (A real life 10% time project!)

F*EX – File EXchange – F*EX (Frams' Fast File EXchange) is a service to send big (large, huge, giant, …) files from a user A to a user B. The sender uploads the file to the F*EX server using a WWW upload form and the recipient automatically gets a notification e-mail with a download-URL.

Enterprise/Authentication/sssd – Ubuntu Wiki – The sssd authentication in Ubuntu works pretty decently. You can use it basically with any directory-style backend, including OpenLDAP, Kerberos, RedHat's FreeIPA and Microsoft's Active Directory. The good part about sssd is that it can be used to log into multiple directory services, so if you have some users in one directory, and the the rest in a different place, this works pretty decently in sssd. You can use it for single-server deployments with plain LDAP with servers or workstations (where you could as well go with pam-ldap and nss-ldap), but also, or especially for more sophisticated setups.

S3QL – nikratio – S3QL is a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack. S3QL effectively provides a hard disk of dynamic, infinite capacity that can be accessed from any computer with internet access running Linux, FreeBSD or OS-X. S3QL is a standard conforming, full featured UNIX file system that is conceptually indistinguishable from any local file system. Furthermore, S3QL has additional features like compression, encryption, data de-duplication, immutable trees and snapshotting which make it especially suitable for online backup and archival. S3QL is designed to favor simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection and error handling have been included from the very first line, and S3QL comes with extensive automated test cases for all its components.
Using Foreman, an Opensource Frontend for Puppet - – The recent vulnerability in bash, got me running to update bash. It’s easy when you have maybe one or two Linux servers, but what do you do if you have 100’s or even thousands or servers? You need to use a server configuration and management tool like puppet. However, instead of using the command line, I wanted a GUI tool where I could select the servers or server group and select an action. That is where I found Foreman, A opensource tool which not only handles configuration of your servers but also does provisioning. Foreman is easy to install, opensource, has community based support and a good deal of documentation.
Power Up Your Authentication with Open LDAP and Puppet | DataCentred – When you’re busy automating your infrastructure, a recurring theme that causes questions and problems is this: how do you reliably integrate your data (which changes all the time) into your configuration? As a hosting company, we find ourselves needing to tend to an ever-increasing number of devices: servers, switches, routers, hypervisors, you name it. A staple mechanism for centralised authentication is the use of an LDAP server to manage a directory of users and groups and to perform authentication of credentials and privileges on behalf of other devices on the network.
Enterprise/Authentication/KerberosServices – Ubuntu Wiki – This article explains a little bit about the Kerberos protocol and how it can be used in Ubuntu. It's not a thorough manual, use more authoritative sources to get more accurate information and update if you see obvious mistakes.
debsecan – The debsecan program evaluates the security status of a host running the Debian operation system. It reports missing security updates and known vulnerabilities in the programs which are installed on the host. debsecan accesses the dpkg database and obtains a list of installed packages and their versions. This list is then evaluated against a feed of vulnerability information which ultimately comes from a database maintained by Debian's Testing Security Team . Various output formats are supported, including incremental reporting via email. Beginning with version 0.2, debsecan includes a script called debsecan-create-cron, which allows you to create a cron job which periodically sends you mail (once per day) when the security status of the system changes.
Barriers, Caches, Filesystems | monolight – With the recent proliferation of ext4 as the new “default” Linux filesystem there’s been much talk of write barrier support. The flurry of post-2.6.18 barrier related development in most storage subsystems has left some novice users and administrators perplexed. I hope I can clear it up a bit with this primer/refresher.
SMTP, testing via Telnet – FreeBSDwiki – When troubleshooting problems with SMTP service – your own, or others – it is frequently very helpful to be able to "speak" to the SMTP server directly, rather than going through a mail client which won't necessarily tell you exactly what the SMTP server is saying. You can easily do this with the telnet client. Note that many ISPs do not allow outbound connections on port 25 to any SMTP server but their own – if you get timeouts when trying to connect to port 25, you should try port 587, which is the standard ESMTP port. (Port 587 connections normally require SMTP AUTH, which is covered below.)
