- One Thing Well | Let’s Encrypt – Let’s Encrypt is now in public beta and offers a command line tool that makes the process of getting and renewing certificates easy, but you have to run it as root, and it’s designed to rewrite your web server’s configuration files. Here’s a selection of alternative tools and clients:
- Tsung – It can be used to stress HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and Jabber/XMPP servers. Tsung is a free software released under the GPLv2 license. The purpose of Tsung is to simulate users in order to test the scalability and performance of IP based client/server applications. You can use it to do load and stress testing of your servers. Many protocols have been implemented and tested, and it can be easily extended. It can be distributed on several client machines and is able to simulate hundreds of thousands of virtual users concurrently (or even millions if you have enough hardware …). Tsung is developed in Erlang, an open-source language made by Ericsson for building robust fault-tolerant distributed applications. [ via http://onethingwell.org/post/134852940551/tsung ]
- Internet Redundancy with ASA SLA and IPSec – PacketU – I’ve seen a lot of examples of redundant Internet connections that use SLA to track a primary connection. The logic is that the primary Internet connection is constantly being validated by pinging something on that ISP’s network and routing floats over to a secondary service provider in the event of a failure. I was recently challenged with how this interacted with IPSec. As a result I built out this configuration and performed some fairly extensive testing.

- ipfs/ipfs · GitHub – IPFS (the InterPlanetary File System) is a new hypermedia distribution protocol, addressed by content and identities. IPFS enables the creation of completely distributed applications. It aims to make the web faster, safer, and more open. IPFS is a distributed file system that seeks to connect all computing devices with the same system of files. In some ways, this is similar to the original aims of the Web, but IPFS is actually more similar to a single bittorrent swarm exchanging git objects. You can read more about its origins in the paper IPFS – Content Addressed, Versioned, P2P File System. IPFS is becoming a new major subsystem of the internet. If built right, it could complement or replace HTTP. It could complement or replace even more. It sounds crazy. It is crazy. [ via http://blog.quintarelli.it/2015/12/ipfs-davvero-figo.html ]
- SSL Library mbed TLS / PolarSSL: Download for free or buy a commercial license – mbed TLS (formerly known as PolarSSL) makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) products, facilitating this functionality with a minimal coding footprint.

- /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/ ]
