Funny OpenDNS, VirtualBox and Debian weirdness

2013/12/16

I was trying to install a virtual machine using the latest VirtualBox on a Windows 7 Host. The host was also running OpenDNS DNSCrypt 0.0.6 client. The guest operating system should be Debian/LXDE. Installation went fine until the installer tried to contact Debian mirrors to fetch missing packages.

It couldn’t find them. Like the common system administration mantra says:

Everything is a DNS problem.

So at the OpenDNS DNSCrypt client dashboard I (temporarily) disabled the DNS over TCP option and the installation continued smoothly. The same thing does not happen with OS X Mavericks as the host operating system. After the installation is finished, you can reenable DNS over TCP for DNSCrypt. The guest operating system’s resolver sees no issues with this.

I am posting this short note because it may bite others out there.
