  • /bin/bash based SSL/TLS tester: testssl.sh – testssl.sh is a free command line tool which checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more. [ via quasi.dot: https://delicious.com/farmando ]
  • Policy NAT for L2L VPN • LearnIOS.com – I kind of missed the wood for the trees here. The static policy NAT is failing because you are trying to map a network 192.168.0.0 to a single IP address 172.20.n.1. However it's just occured, why are you doing policy NAT for the Internet. I tested in lab and if you do this
  • Encrypted Data Bags on Cloud on AWS – Many customers have asked us how they should handle shared secrets, passwords and other sensitive data in Chef and now we have a good solution. With the release of our stable-v4 stack, we introduced Chef 10 to the platform, and with it came data bags. Now with the 3.0 release of the engineyard gem, we can officially support data bags and encrypted data bags. You may be wondering what data bags are, how data bags work or how to implement data bags. This blog post will walk you through the entire process.
  • How to set disk alignment in Linux | Dirty Cache – As you might know, if disk partitions containing Oracle datafiles are not aligned with the underlying storage system, then some I/O’s can suffer from some overhead as they are effectively translated in two I/O’s. If you want more info, google for “EMC disk alignment” and you’ll find plenty of information, explaining the issue.
  • Add Private Route 53 DNS to your AWS VPC | CloudTrek – A really cool feature of Amazon’s Route 53 DNS Management Service is the private hosted DNS zone.  Basically, you get the ability to manage the DNS in your private VPC without setting up your own DNS infrastructure (yuck!) [ Just a friendly reminder Note 1: the resolution is working only inside the VPC. Note 2: if you don't have the AmazonProvidedDNS in your DHCP-OPTION you won't resolve the zone. Note 3: if you are using linux, you can use as DNS 169.254.169.253 it won't work on windows 2008 Ref: http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_DHCP_Options.html http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/hosted-zones-private.html http://aws.amazon.com/route53/faqs/ ]

  • FhGFS Wiki: Tips and Recommendations for Storage Server Tuning – Here are some tips and recommendations on how to improve the performance of your storage servers. As usual, the optimal settings depend on your particular hardware and usage scenarios, so you should use these settings only as a starting point for your tuning efforts.
  • Linux NAS optimizations ← BAFM – […] Well, I recently had to flatten my archive NAS (well only the OS part … *wheeeh*). Since I didn’t have the chance to backup the old settings I had to do everything from scratch … And this time I decided, I wasn’t doing a script but rather the proper way. I spent a while reading through the Internetz about the various settings until I stumbled upon a Frauenhofer Wiki entry. From there I ended up writing those udev-rules and the sysctl configs…[…]
  • Some MySQL security tips | code.openark.org – This is a brief list of security tips for MySQL. It is by no means complete.
  • openarkkit – Common utilities for MySQL – Google Project Hosting – The openark kit provides common utilities to administer, diagnose and audit MySQL databases.
  • outbrain/orchestrator – MySQL replication topology manager/visualizer

  • ZPanel | The free web hosting panel – ZPanel is an easy to use, enterprise class web hosting control panel with support for unlimited resellers. From the largest business to SOHO or development environments, ZPanel can support your needs.
  • Bucky — Performance Measurement of Your App’s Actual Users – Bucky is a client and server for sending performance data from the client into statsd+graphite, OpenTSDB, or any other stats aggregator of your choice. It can automatically measure how long your pages take to load, how long AJAX requests take and how long various functions take to run. Most importantly, it's taking the measurements on actual page loads, so the data has the potential to be much more valuable than in vitro measurements. If you already use statsd or OpenTSDB, you can get started in just a few minutes. If you're not collecting stats, you should start! What gets measured gets managed.
  • Linux on 4 KB sector disks: Practical advice – Advanced Format disks use 4,096-byte sectors rather than the more common 512-byte sectors. This change is masked by firmware that breaks the 4,096-byte physical sectors into 512-byte logical sectors for the benefit of the operating system, but the use of larger physical sectors has implications for disk layout and system performance. This article examines these implications, including benchmark tests illustrating the likely real-world effects on some common Linux file systems. As Advanced Format disks have become the norm, understanding how to cope with these disks is a vital skill for anyone who wants to avoid serious performance penalties associated with suboptimal configuration.
  • WPScan by the WPScan Team – WPScan is a black box WordPress vulnerability scanner.
  • SiteSucker for OS X – SiteSucker is a Macintosh application that automatically downloads Web sites from the Internet. It does this by asynchronously copying the site's Web pages, images, backgrounds, movies, and other files to your local hard drive, duplicating the site's directory structure. Just enter a URL (Uniform Resource Locator), press return, and SiteSucker can download an entire Web site. [ via http://onethingwell.org/post/79174700058/sitesucker ]

  • Epoptes – Epoptes (ΕπÏŒπτης  – a Greek word for overseer) is an open source computer lab management and monitoring tool. It allows for screen broadcasting and monitoring, remote command execution, message sending, imposing restrictions like screen locking or sound muting the clients and much more! It can be installed in Ubuntu, Debian and openSUSE based labs that may contain any combination of the following: LTSP servers, thin and fat clients, non LTSP servers, standalone workstations, NX or XDMCP clients etc. Patches for other distros are welcome.
  • bcache – Bcache is a Linux kernel block layer cache. It allows one or more fast disk drives such as flash-based solid state drives (SSDs) to act as a cache for one or more slower hard disk drives. Hard drives are cheap and big, SSDs are fast but small and expensive. Wouldn't it be nice if you could transparently get the advantages of both? With Bcache, you can have your cake and eat it too. Bcache patches for the Linux kernel allow one to use SSDs to cache other block devices. It's analogous to L2Arc for ZFS, but Bcache also does writeback caching (besides just write through caching), and it's filesystem agnostic. It's designed to be switched on with a minimum of effort, and to work well without configuration on any setup. By default it won't cache sequential IO, just the random reads and writes that SSDs excel at. It's meant to be suitable for desktops, servers, high end storage arrays, and perhaps even embedded.
