The Cyrus IMAP server (which is used by FastMail, FYI), is pretty picky when it comes to enforcing RFCs.  When performing a recent email migration (from Zoho, which is less picky), I got a boatload of errors along the way. With each of my messages as individual files (downloaded as […]

IMAP Append – Message contains bare newlines


There are times when I need to create a number of OpenVZ containers in Proxmox at once, which would take way too long via the user interface.  There are a number of ways to accomplish this programmatically, but the most straightforward (assuming you have root access) is via [crayon-59c94d5a4c539578178805-i/] .

Migrating from one Chef server to another


Just about every significant aspect of Chef Server is configurable, although the defaults are okay for most.  The configuration options are documented at http://docs.opscode.com/config_rb_chef_server_optional_settings.html . Note, though, that the chef-server.rb described in the article was nowhere to be found on my server.  Instead, after some digging, I found what I needed at [crayon-59c94d5a4d7dc056853301-i/] . […]

Using autofs with a NAS in Chef



I love OpenVZ, but I was unfortunately never able to successfully install Chef Server in a container; I’ve always had to try it out on KVM or Xen instead. The culprit was the procps package, which refused to install as a dependency. After looking into it, it turns out that […]
