  • LDAP org chart | – For centralised authentication and authorisation, LDAP is the de-facto standard. Whether in its pure form on Unix or in Active Directory guise on Windows, everyone uses it. What many people don't realise is that you can store all sorts of useful (and not so useful) information in LDAP. One field which can be useful is the "manager" attribute. One of our customers use that and so we've written a small script to graph it using the excellent Graphviz tool. It will probably need customising for specific cases, however we hope that people find it useful nonetheless. If you want to alter the output, do have a look at the record format documentation.
  • Puppet errors explained | – Puppet is a wonderful system automation tool, however the learning curve can be a little steep. We've collected some of the errors messages and "strange" behaviour you may come across together with explanations to help overcome these hurdles and boost adoption of this fabulous tool. If you have any useful errors and explanations, please do send them in and we'll update this article.

  • DNS Load Balancing and Using Multiple Load Balancers in the Cloud – [...] Load balancing in general is a complicated process, but there's some secret sauce in managing DNS along with multiple load balancers in the cloud. It requires that you draw from a few different sets of networking and “cloudy” concepts. In this second article in my best practices series (my first post covered how to use credentials within RightScale for storing sensitive or frequently used values), I'll explain how to set up load balancers to build a fault-tolerant, highly available web application in the cloud. Here's what you’ll need: Multiple A records for a host name in the DNS service of your choice Multiple load balancers to protect against failure [...]
  • gdnsd – gdnsd is an Authoritative-only DNS server which does geographic (or other sorts of) balancing, redirection, weighting, and service-state-conscious failover at the DNS layer. gdnsd is written in C using libev and pthreads with a focus on high performance, low latency service. It does not offer any form of caching or recursive service, and notably does not support DNSSEC. There's a strong focus on making the code efficient, lean, and resilient. The code has a decent regression testsuite with full branch coverage on the core packet parsing and generation code, and some scripted QA tools for e.g. valgrind validation, clang-analyzer, etc. The geographically-aware features also support the emerging EDNS Client Subnet draft for receiving more-precise network location information from intermediate shared caches.

  • Use vim at its best to edit your Puppet manifests – Linuxaria – Using this repository you’ll enable the following plugins: pathogen Makes it super easy to install plugins and runtime files in their own private directories. snipmate.vim snipMate.vim aims to be an unobtrusive, concise vim script that implements some of TextMate’s snippets features in Vim. syntastic Syntastic is a syntax checking plugin that runs files through external syntax checkers and displays any resulting errors to the user. This can be done on demand, or automatically as files are saved. If syntax errors are detected, the user is notified and is happy because they didn’t have to compile their code or execute their script to find them. tabular Sometimes, it’s useful to line up text. Naturally, it’s nicer to have the computer do this for you, since aligning things by hand quickly becomes unpleasant. vim-puppet Make vim more Puppet friendly! vim-fugitive Provides an amazingly deep Git integration for vim.

  • How to Run Internet Explorer 7, 8 and 9 in Linux with or without Wine – How to Run Internet Explorer 7, 8 and 9 in Linux with or without Wine
    Microsoft have a wonderfully long history of badly designed software that they're proudly continuing to this day with the abomination of IE 9 and the ghastly sham that is Windows 7. It's a tribute to the skills of the many hard-working marketing heads over at Redmond that despite the poor quality and the easy availability of superior cost-free alternatives, people the world over keep coming back to Microsoft like hookers on crack.
