Step 1: Download the Debian network installer I updated it to show the procedure for installing Debian 8 in VirtualBox 5. NOTE: This post was updated on January 4, 2016. Also, Debian is a conservative Linux distribution so we can be fairly confident that if we run into issues, we will not need to debug the operating system. We will install Debian Linux because it is the version of Linux that is used by most of the researchers who have developed the network simulation tools we wish to investigate.

Install the Debian Linux operating system on the virtual machine.Boot the virtual machine from the DVD image we downloaded.Create a virtual machine using the VirtualBox application.A summary of the procedures is listed below: Verify that the calculated hash is the same as the one in SHA512SUMS: $ openssl dgst -sha512 ~/Downloads/debian-6.0.5-i386-netinst.iso To be extra safe, verify that the primary key fingerprint exists on this page: Subsequent runs will look something like this: Gpg: There is no indication that the signature belongs to the owner. Gpg: WARNING: This key is not certified with a trusted signature! Gpg: Good signature from 'Debian CD signing key ' Gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model Gpg: key 6294BE9B: public key 'Debian CD signing key ' imported Gpg: requesting key 6294BE9B from hkp server Gpg: Signature made Sun May 13 05:01:57 2012 PDT using RSA key ID 6294BE9B You should see something like this the first time you run gpg -verify: work fine, but as long as we're being paranoid, we might as well go all the way) Also download the SHA512SUMS and SHA512SUMS.sign files. HOWTO: Verify Debian ISO Downloads (from OS X)
