How to convince apt-get NOT to use IPv6

Recently I installed a Debian 7 VPS on Linode and as first thing I wanted to do an update of the system, but I found a small problem in doing this :

# apt-get update
0% [Connecting to ftp.us.debian.org (2610:148:1f10:3::89)] [Connecting to security.debian.org (2607:ea00:101:3c0b:207:e9ff:fe00:e595)]
Get:1 http://ftp.us.debian.org wheezy Release.gpg [1,672 B]                                                                           
...
Get:15 http://security.debian.org wheezy/updates/main Translation-en [56.6 kB]
Fetched 16.3 MB in <strong>4min 0s</strong> (67.5 kB/s)                                                                                                                                     
Reading package lists... Done

So 4 minutes to just update my repositories (and I had just the default for a Debian 7 just installed), this is due to the fact that linode VPS are IPV6 ready and so the servers of this company try to connect to security.debian.org via its IPv6 address by default when running apt-get update, and that results in having to wait for a lengthy timeout whenever you try to download updates of any sort.

But luckily change the system so apt-get will use IPV4 it’s not so hard.

After the last article of Dropbox I thought it was useful to show how you can use Dropbox also on a server without a GUI, this useful article by David Feinberg was published on http://ubuntuservergui.com/

This post will help you install the Linux Dropbox client on your headless Ubuntu Server and link it up to your Dropbox account. Unlike the process of mounting an S3 bucket we looked at before the Dropbox approach is a much better solution for sharing files. If you’re a daily Dropbox user you’ll quickly get hooked on the convenience of having your servers in the same file sharing loop as all your other Dropbox connected devices!
