Why Novell and Netware with it went titsup
I previously wrote about why Madge Networks went titsup here. This triggered discussions and thoughts about Novell, the Big Red.
In the early nineties my first LAN installation were done using IBM
PS/2 servers running LAN Manager from IBM on token-ring. I then started
work at a company who did Novell Netware installations. I started on
Netware 3.11 but often had to support Netware 2 installation. This was
the days of DOS and OS/2. It was the days before the Internet where
drivers updates and bugfixes were downloaded from a BBS using 9.6k baud
modem. It had to be a US Robotics and I can safely say I spend more time
with that modem than anything else. All software came shrink wrapped.
The Novell Software came in a Big Red box, shipped freshly shrink wrapped from the Mormons.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.

I, too, thought that was a good idea in the beginning, but experience has shown that there are serious pitfalls to this approach.
