When your FSDP Cluster account is created, you should receive an email with your OpenVPN client configuration attached.
Linux Users: Linux users should use the OpenVPN client supplied with their distribution. Users of modern Linux distributions may import this file as-is into NetworkManager. When using OpenVPN from the command line, DNS may fail to resolve. There are instructions at the bottom of the configuration file to try to solve this issue.
Windows Users: Install the OpenVPN client from here. You may use the configuration as-is with this client. You may need to run OpenVPN as administrator for the routes to be set up correctly once connected.
Mac Users: Install TunnelBlick from here. You may need to run with administrative privileges for the routes to be set up correctly once connected.
Usage of this VPN connection is contingent upon agreement with the UNH-IOL Usage Agreement.
You are expected to be physically present at your local system whenever it is connected to the VPN.
Note that this file contains private key material and you are expected to keep it appropriately secure. E-mail ofalab@iol.unh.edu immediately if your VPN credentials have been compromised.
Connect to the build server via ssh:
ssh <username>@builder-00.ofa.iol.unh.edu
The first time you log in, you should use the initial password given in the welcome email you received. You will immediately be required to change your password upon first login.
The containers for Fedora-based images are maintained by the cki-project.
Instructions for accessing and running these images using rootless podman can be found below.
Run the following command:
podman run -it registry.gitlab.com/cki-project/containers/builder-fedora
You should now be running the container image from the registry.
Run the following command:
podman run -it registry.gitlab.com/cki-project/containers/builder-rawhide
You should now be running the container image from the registry.

To enable cluster users to easily move artifacts from their build environments to the test nodes, the build servers have been configured to support user public_html directories. You will need to take the following steps to create a public_html root in your home directory. Note, any files placed this directory will be made available to all logged in users in the cluster unless you take the optional steps below to add a password (http basic authentication).
Required:
- Create the directory,
mkdir ~/public_html
Optional, to protect your artifacts from other snooping eyes (replace USERNAME with your username on the system):
- Create an .htaccess file with the contents below,
vim ~/public_html/.htaccess - Create your password,
htpasswd -c ~/public_html/.htpasswd USERNAME
AuthType Basic
AuthName "Password Required"
Require valid-user
AuthUserFile /home/USERNAME/public_html/.htpasswd
