  • sebsauvage/rss-bridge – The RSS feed for websites missing it
  • 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.)

  • muquit/mailsend – mailsend is a simple command line program to send mail via SMTP protocol. I needed to send a piece of alert mail from a program in a networked Windows machine, but could not find a simple program like this installed. So I wrote one. You might find it useful in some situations. The program does not use any config file and I plan to keep it that way.
  • visit1985/mdp – A command-line based markdown presentation tool.
  • Teampass · A Collaborative Passwords Manager – TeamPass is a Passwords Manager dedicated for managing passwords in a collaborative way on any server Apache, MySQL and PHP.

  • Hughes Systique Corp. > Research & Innovation > Newsletter > Issue 2 > mySQL – A typical MySQL cluster requires at least 4 nodes for deploying a High Available MySQL database cluster. The typical configuration of any enterprise application is a 2 Node solution (Active-Standby mode or Active-Active Mode). This is where the real challenge lies: in fitting the MySQL Cluster Nodes in the 2 Nodes offering the application services and then making it work in the configuration without a single point of failure.
  • Corosync / Pacemaker – Execute script on failover – Raymii.org – With Corosync/Pacemaker there is no easy way to simply run a script on failover. There are good reasons for this, but sometimes you want to do something simple. This tutorial describes how to change the Dummy OCF resource to execute a script on failover. In this example it is a script which triggers a few SNMP traps, sends an alert to Nagios and sends some data to Graphite. SNMP alone could be done with the ocf:heartbeat:ClusterMon resource, but the other stuff not.
  • Home – A Banana Pi powered website
  • UrBackup – Client/Server Open Source Network Backup for Windows and Linux – UrBackup is an easy to setup open source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time. File and image backups are made while the system is running without interrupting current processes. UrBackup also continuously watches folders you want backed up in order to quickly find differences to previous backups. Because of that incremental file backups are really fast. Your files can be restored through the web interface or the Windows Explorer while the backups of drive volumes can be restored with a bootable CD or USB-Stick (bare metal restore). A web interface makes setting up your own backup server really easy.

  • How to write udev rules – Since the adoption of Kernel 2.6, Linux has used the udev system to handle devices such as USB connected peripherals. If you want to change the behavior when you plug something into a USB port, this section is for you. As an example, we will use a USB thumb drive but these methods should translate to any device handled by udev. As a goal for this exercise we decided to create a symlink and execute a script when a specific thumb drive was loaded.
  • Persistent iSCSI LUN Device Name – jablonskis – […] I spent a bit of time figuring out how to get this achieved, so thought it is worth noting for the future reference. I will try to make this quick assuming you have knowledge about iSCSI software initiators in Linux[…]
  • al3x/sovereign – A set of Ansible playbooks to build and maintain your own private cloud: email, calendar, contacts, file sync, IRC bouncer, VPN, and more.
  • NSA-proof your e-mail in 2 hours | Sealed Abstract – You may be concerned that the NSA is reading your e-mail. Is there really anything you can do about it though? After all, you don’t really want to move off of GMail / Google Apps. And no place you would host is any better. Except, you know, hosting it yourself. The way that e-mail was originally designed to work. We’ve all just forgotten because, you know, webapps-n-stuff. It’s a lot of work, mkay, and I’m a lazy software developer.

  • tmux-plugins/tmux-resurrect – Restore tmux environment after a system restart. Tmux is great, except when you have to restart the computer. You lose all the running programs, working directories, pane layouts etc. There are helpful management tools out there, but they require initial configuration and continuous updates as your workflow evolves or you start new projects. tmux-resurrect saves all the little details from your tmux environment so it can be completely restored after a system restart (or when you feel like it). No configuration is required. You should feel like you never quit tmux. http://undeadly.org/cgi?action=article&sid=20140904174329
  • box/Anemometer – This is the Box Anemometer, the MySQL Slow Query Monitor. This tool is used to analyze slow query logs collected from MySQL instances to identify problematic queries.
  • SpamExperts/pyzor – Pyzor is a Python implementation of a spam-blocking networked system that use spam signatures to identify them.

  • Scaling PHP apps via PHP-FPM clustering | Jamie Alquiza – PHP-FPM is a way to move your busted PHP handling from one place to another. It's essentially a pool of processes ready for PHP interpretation through FastCGI. While Apache will service client connections and static content, PHP requests are pushed into PHP-FPM. PHP-FPM allows the creation of process pools, each pool having it's own spawning model (e.g. static number of processes, dynamic with min/max, etc.) and other configurations (what UID/GID to run as, listening socket, etc.). A typical setup would be to create a PHP-FPM pool per tenant in a shared hosting environment.
  • KERMIT – KermIT is an opensource IT management solution. KermIT integrates best of breed opensource components with a Web user interface and dashboard to provide a central management solution for IT systems and applications. It provides a consistent, secure framework and a scalable architecture. It manages Linux, Unix and Windows systems. 'Small picture' KermIT relies in the backend on Puppet and MCollective. The license of the developments is the GPL v.3 for the generic part of the source code.
  • Random Start Times For Cron Jobs With Puppet : mycfg.net – Periodic scripts which use a common resource can end up being configured to run at the same time for multiple hosts. The result is that tasks like puppet runs or backups can take longer since they are trying to run all at once instead of being staggered. One way to do this is to give each cron task unique times manually. Another way is to add a random sleep before the task runs. My preferred way is to use the fqdn_rand function in puppet. Here's how it works.

  • CloudInit – Community Help Wiki – cloud-init is the Ubuntu package that handles early initialization of a cloud instance. It is installed in the Ubuntu Cloud Images and also in the official Ubuntu images available on EC2. Some of the things it configures are: setting a default locale setting hostname generate ssh private keys adding ssh keys to user's .ssh/authorized_keys so they can log in setting up ephemeral mount points cloud-init's behavior can be configured via user-data. User-data can be given by the user at instance launch time. This is done via the –user-data or –user-data-file argument to ec2-run-instances
  • Tsunami UDP Protocol – Tsunami UDP Protocol: A fast user-space file transfer protocol that uses TCP control and UDP data for transfer over very high speed long distance networks (≥ 1 Gbps and even 10 GE), designed to provide more throughput than possible with TCP over the same networks. The project is based on original Indiana University 2002 Tsunami source code, but has been significantly improved and extended. As such, large portions of the program today are courtesy by Aalto University Metsähovi Radio Observatory. Includes FTP-like client and server command line applications for normal file transfers. It has additionally been extended for high rate real-time data streaming in eVLBI radio astronomy and geodesy (VSIB, PCEVN DAQ). Licensed under the original IU open source license.
