IPv6 and IPv4 name resolution with Go

As part of a work-related project, I'm writing code that needs to resolve DNS names using Go, on illumos.

While doing this work, I noticed a very surprising thing.  When a host has both IPv6 and IPv4 addresses associated with a name (such as localhost), Go prefers to resolve to the IPv4 version of the name, unless one has asked specifically for v6 names.

What to do next after spinning up a Debian VPS

Configure Postfix to use a remote SMTP relay server via alternate port

On one of my local Ubuntu workstations at home, I sometimes have the need to send mail out using mailutils/mailx inside of scripts or on the command line.

Creating a local ownCloud mount point in Linux using WebDAV

ownCloud is enterprise file sync and share that is self-hosted in your data center, on your servers, using your storage. ownCloud provides Universal File Access through a single front-end to all of your disparate systems. Users can access company files on any device, anytime, from anywhere while IT can manage, control and audit file sharing activity to ensure security and compliance measures are met.
WebDAV (Web Distributed Authoring and Versioning) allows you to "mount" your ownCloud content as a local mount point on your local Linux environment.
