Kerberos and NFS4 on Linux Workshop

There are three practical parts in this workshop that form a unit.

Slides of the presentation during the workshop.

Convention

• When asked for the password for a kerberos ticket always use the ETH password for email.
• Commands with a # prompt must be run as root, commands with a $ prompt as the local user with the same uname as your ETH user name.
• In all example text and code, anything between braces, e.g., {your ETH user name}, is a placeholder.

Preparations

At the beginning of the workshop you get a generic Ubuntu, CentOS 7 or Fedora installation on a VM. You will get the password for root.

Perform the following steps:

Log in as root

After login change the password for root to something only you know. Alternatively you can add your SSH public key to /root/.ssh/authorized_keys. Once you can successfully log in via public key, you can set the password for root to a random one.

Create a local user with your ETH user name.

Run the following commands and substitute {your ETH user name} with your ETH user name. Please use your ETH password for email:

Update and Install Software

Update the system once to be up to date:

Ubuntu

# apt -y update && apt -y full-upgrade

CentOS

# yum clean all ; yum upgrade -y

Fedora

# dnf --refresh upgrade -y

If there were any packages that were updated then run reboot, otherwise continue.

After a minute log in again as root and install all basic software packages needed for the three parts below:

Ubuntu

# apt -y install curl wget vim nano

CentOS

# yum install -y curl wget vim nano

Fedora

# dnf install -y wget curl vim nano
