Release Info

The OpenBSD team makes a new release every six months with target release dates in May and November.

OpenBSD 4.7 was released on May 19, 2010.

Remote Simple Installation of OBSD 4.7

What follows is a demonstration of an OpenBSD ftp installation on an i386 computer.

This demonstration will show a clean install, meaning any operating system or information already on the computer will be erased. You can dual-boot OpenBSD with FreeBSD, Linux, Windows or other operating systems but that type of setup will not be discussed here.

Step 1 - Obtaining OpenBSD - how to obtain OpenBSD for free
Step 2 - Installer program - create a bootable CD or floppy install program
Step 3 - Starting the simple installation - booting into the installation program
Step 4 - Post Install - reading the afterboot man page

Step 1 - Obtaining OpenBSD

There are 3 popular methods for obtaining OpenBSD:

» Purchase a hard copy: Show your support for the open source community and keep the OBSD project going.
» Using OpenBSD's ftp installer: This tutorial explains the ftp installation and requires an online connection.
» Using the OpenBSD 4.7 ISO image: The ISO image will contain the entire OS (including sets).

Purchasing a hard copy of OpenBSD will get you the entire OS, along with the source code, installation instructions and other miscellaneous things on 3 CDs. But if you are a first time user just download the installer and take OpenBSD out for a test drive before you decide to buy.

Step 2 - Installation Program

In order to remote install OpenBSD an installation program from openbsd.org will be used. This installation program will be loaded onto a computer using either a floppy disk or CD-R, the CD-R being created by an ISO image.

There are different ISO images and floppy files for laptops, servers and desktop PCs. Go here to determine which file is right for you.

If you are using a desktop PC you will more than likely use one of these:

Floppy file for desktop PCs (remote install): ftp://ftp.openbsd.org/pub/OpenBSD/4.7/i386/floppy47.fs
CD-R image for desktop PCs (remote install): ftp://ftp.openbsd.org/pub/OpenBSD/4.7/i386/cd47.iso
CD-R install image for desktop PCs (local install): ftp://ftp.openbsd.org/pub/OpenBSD/4.7/i386/install47.iso

The two OpenBSD CD ISO files

install47.iso - The entire OpenBSD 4.7 installation (including sets) will be packaged in this 250 meg ISO file and will allow the user to install OpenBSD without an online connection.
cd47.iso - This 5 meg ISO file contains the remote installation program and is used if the user wants to install OpenBSD remotely.

If you have a fast connection I recommend downloading the install47.iso file (250 megs in size). Using this file for an install will contain all installation sets and will not require an internet connection when installing OpenBSD.

I will not go into detail on the proper way to copy these files to a floppy or CD-R so they are bootable.

But briefly

To create a bootable floppy disk using Windows XP (NTFS) you will need the program, ntrw.exe.
Create the floppy with the following command format: ntrw <image file> <floppy drive>
So at a command prompt (DOS prompt) type: ntrw floppy47.fs a:
To create a bootable floppy disk using Linux use the following command: cp floppy47.fs /dev/fd0
To create a bootable CD-R from an ISO image with Windows XP a tutorial can be found here.
To create a bootable CD-R from an ISO image with Linux a tutorial can be found here.

Note: If you are a Linux user and have downloaded an entire Linux distro on a set of ISOs (such as Fedora and Slackware) then you will notice the bootable ISO for OpenBSD (cd47.iso) is different. The OpenBSD ISO is 5 megs in size and acts as an installation program that will go on-line to download the entire operating system after the initial system setup.

Step 3 - Starting The Remote Simple Installation

Okay now we have either a bootable floppy disk or a bootable CD-R which contains the installation program.

You should also remember to have your computer connected on-line unless the OpenBSD sets are located locally. This connection will be configured during the installation process in order to do a remote install.

Boot your computer up using the install floppy or CD-R.

The screen below starts after the boot process and shows the start of the installation program, red text is user input:

root on rd0a swap on rd0b dump on rd0b
erase ^?, werase ^W, kill ^U, intr ^C, status ^T

At any prompt except password prompts you can escape to a shell by
typing '!'. Default answers are shown in []'s and are selected by
pressing RETURN.  You can exit this program at any time by pressing
Control-C, but this can leave your system in an inconsistent state.

CONGRATULATIONS! Your OpenBSD install has been successfully completed!
To boot the new system, enter 'reboot' at the command prompt.
When you login to your new system the first time, please read your mail
using the 'mail' command.

# halt
syncing disks... done

The operating system has halted.
Please press any key to reboot.

Remove the bootable floppy disk or bootable CD-R, then reboot. Have fun and enjoy.

Post Install - After the first boot

After rebooting a user will want to next read the afterboot man page. This document attempts to list items for the system administrator to check and set up after the installation and first complete boot of the system.

Reading the afterboot man page:

# man afterboot

If you notice any errors, please let me know.
