Ubuntu Differences (Domino-Focused)

Introduction

This document describes the differences when installing and running HCL Domino on Ubuntu Linux.

Update Linux

apt update
apt upgrade -y
reboot

Equivalent to:

dnf -y update

Install Required Domino Packages

apt install -y gdb perl tar unzip 

Extra Repositories

On Redhat/CentOS based systems some useful tools are not included in the standard repositories. You have to install the extra EPEL packages.

dnf install epel-release

On Ubuntu most packages are in the standard repository. There are still some specific packages which are part of the universe repository, which might not be configured by default.

Additional Tools (Optional but Recommended)

apt install -y jq git ncdu net-tools dnsutils sysstat

Firewall Configuration (Domino Ports)

Ubuntu uses UFW instead of firewalld

Enable required Domino ports

ufw allow 1352/tcp   # NRPC
ufw allow 80/tcp     # HTTP
ufw allow 443/tcp    # HTTPS
ufw allow 25/tcp     # SMTP
ufw enable

Summary

Area	RHEL-based	Ubuntu
Package manager	yum / dnf	apt
