386BSD 1.0 Running on Qemu
DICLAIMER: This software is a component of “386BSD” developed by William F. Jolitz, TeleMuse.
Please review the full COPYRIGHT NOTICE before continuing.
With Qemu I was able to install and run 386BSD 1.0 Jolix (circa 1989-1994). It is not for the faint of heart. The public downloaded zip file came with no floppies, no CDROM, no installer; only the OS binaries. I had to figure out many things by trial and error, rinse and repeate: the best hard drive image format, dumping the OS binaries remotely, labeling the bootstrap, and fine tuning the startup procedures. Many undocumented steps were involved. I will possibly work on the step-by-step instructions once I am able to re-compile and figure out a stable running install.
386BSD is a historical and legendary operating system, because it is the first Unix that was ported to the Intel 386 CPU beginning in 1989. This preliminary version paved the way for all the other popular Unix versions in actuality, including FreeBSD, NetBSD and the like. This release, together with Minix, is part of the foundations of the modern Unix and Linux for the 386; it is a great academic point of reference for operating system porting and development today, especially for the x86 personal computer architecture; and TCP/IP networking, which also originated with the earlier 4.2BSD Unix.
Unix BSD/OS 4.3 Install on Qemu 386
Overview
A practical approach for the Qemu 386 install of the operating system from Berkeley Software Design BSD/OS 4.3 (2002). Installing and running a legacy Unix system is a great point of reference concerning the study and appreciation of older operating systems. BSD/OS 3.x to 5.x also install in a very similar way. The audience is experienced Unix and Linux administrators.
CLARIFICATION: This is the BSD/OS 4.3 version for i386 from 2002, and not the classic 4.3BSD Berkeley Unix for the VAX from 1986. For that install visit Install 4.3BSD Berkeley UNIX with VAX780 SimH Emulator and TCP/IP Networking

Verify OpenSSL TLS 1.2
In an effort to combat cyber crime, major tech companies are advocating encryption for the entire Internet through the free certificate service called “Let’s Encrypt”; meaning that in the not so distant future the following will block public web pages from running browsers:
-
* Web paged running on http port 80
* Web pages with self-signed certificates
* Web pages with weak encryption
* Web pages without TLS 1.2 certified encryption
* Web pages still encrypting with old SSL3
Below find some examples on how to quickly test if your site complies with OpenSSL TLS 1.2.
TLS is supported on OpenSSL 1.0.1 or above. Verify your version:
~$ openssl version OpenSSL 1.1.1d 10 Sep 2019
Verify a TLS 1.2 enabled website by querying its certificate and spotting its cipher at the bottom. If it returns error handshake messages and no cipher, then it probably does not support TLS 1.2. It should return something like this:
