How to get Open BSD iso file.

The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system.

OpenBSD project team efforts emphasize portability, standardization, correctness, proactive securityintegrated cryptography

OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX.

However, OpenBSD Team does not provide ISO image for download, although the they provide ftp server for us to download the package only. They are encourge us to purchase the inexpensive CD from them, to support them development job.

However, now the broadband is very common now, so I had find out a way to downlaod the OpenBSD snapshot by using the wget and creating iso for the snapshot.

Below is how I use my Linux box to download the package and create the iso from snapshot.

shell> mkdir /OpenBSD/i386

shell> cd /OpenBSD/i36

shell> wget ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/i386/*

The download process is in progress

If your Internet connection suddenly drop, you still can resume your download by

shell> wget -c ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/i386/*


After the snapshot has been downloaded, I just need to run the command below to create the iso for it.


shell> cd /OpenBSD/i386


shell> mkhybrid -r -b cdrom38.fs -c "boot.catalog" -o OpenBSD43.iso OpenBSD


After you get the ISO image, you can use any of the ISO burning software to create your bootable disk.

Why use OpenBSD:

"Secure by Default"
To ensure that novice users of OpenBSD do not need to become security experts overnight (a viewpoint which other vendors seem to have), we ship the operating system in a Secure by Default mode. All non-essential services are disabled. As the user/administrator becomes more familiar with the system, he will discover that he has to enable daemons and other parts of the system. During the process of learning how to enable a new service, the novice is more likely to learn of security considerations.
This is in stark contrast to the increasing number of systems that ship with NFS, mountd, web servers, and various other services enabled by default, creating instantaneous security problems for their users within minutes after their first install.
