OpenDNSSEC Training

Introduction

You as a student will have two servers. One will be configured to be the resolver and the other will be the name server hosting your zone.

  • resolverX.odslab.se
  • nsX.odslab.se

X is the group number given to you by the teacher. The IP-addresses of the resolver and the name server are configured directly in the odslab.se zone, and can be used from the beginning.

You will also be working with the domain groupX.odslab.se. This domain is however not present in DNS yet, because that will happen later in the lab.

Connecting to a Server

Use an SSH client (such as OpenSSH or PuTTY) to connect to your servers. The private key will be given to you by the teacher.

OpenSSH

chmod 400 ods-student.pem
ssh -i ods-student.pem ubuntu@ADDRESS

PuTTY

  • Convert the key to PuTTY format using the PuTTYgen, save the result to ods-student.ppk
  • Enter address to server.
  • Use the ods-student.ppk for authentication and log in as the user "ubuntu".

Documentation
