Unix-Related Sites
I realize there are Linux distributions but there are so many of them, this page would be too long and complicated if I tried to include them all.
I run Raspberry Pi OS on several Raspberry Pi computers and Debian on a BeagleBone Black. I'm a fan of Debian, and have Ubuntu and Linux Mint running in several VMs. They allow me to test various systems. I may add a few Linux distributions to this page at some point.
FreeBSD Page- I run FreeBSD (currently version 14.3-stable) on my Dell Poweredge servers at home. FreeBSD is available for many systems, including i386 (ends with version 15), amd64, arm64, powerpc64, and riscv64. One of this free operating system's strong points is TCP/IP networking. Many application programs are available (freeware and commercial) as ports and/or "packages" (precompiled binaries packed with or linked to all the files needed to run the application--installing packages is as simple as typing "pkg_add package-name"). A large team of individuals continues to contribute actively to the development of FreeBSD. Includes Linux emulation.
- NetBSD Page and OpenBSD Page
- NetBSD and OpenBSD are related free unix operating systems (based on the 4.4BSD-lite distribution, as is FreeBSD), although it is fairly safe to say now OpenBSD has found its own niche as a secure system. The NetBSD group tries for maximum portability and stability across platforms, while the OpenBSD group tries for maximum security while retaining portability. These operating systems also are of interest since their software tends to port (mostly) effortlessly to FreeBSD (and vice versa, one presumes).
- Unix Guru Universe Unix SysAdmin Page
- The Official Home Page for Unix System Administrators. The site is broken down into the following areas: (Unix) Flavors, System Administration, Networking, Security, Software (62 categories), Help, Conferences/Shows/Events, Vendors, Careers, and Internet. Too much to describe in a short space.
- 10 Resources every sysadmin should know
- 10 resources like crontab guru, samba, hex keys and screwdrivers, and telnet.
- Unix and Linux System Administration Handbook
- Evi Nemeth, et al, 5th edition, information.
- Perl Reference Page
- A good starting point for learning about Perl, including some system administration tools written in perl.
- sed Sites
- Several links to seders sites, and other information about the sed editor.
- awk Sites
- Several links to sites with awk information, including for GNU awk.
