I have been supporting Unix servers for more than 20 years. When I started, they weren’t even called “servers.”
The first Unix system I worked on was Unix System III running on an Altos 68000 — that was in 1983.
The entire set of man (manual) pages fit into a single, admittedly large, 3-ring binder. We had one megabyte of RAM and a 20 MB hard drive. Compared to the personal computers available at that time, the Altos was at least an order of magnitude more powerful.
The system was a dedicated turn-key billing system which my employer had purchased. I was a billing clerk in the office. We paid a support contract up front for two years that included system administration. This was supposed to be minimal since all anyone was supposed to do was turn it on. When you logged in you got the billing system menus written in DACL.
One day, the Altos had a problem that seemed to be a hardware problem, so I called the vendor. I got The Tone, and a voice saying, “the number you have reached is no longer in service …” Their office was close to ours so I stopped there at lunch; we had 20,000 statements to print! The office was empty. They were gone.
That day, I became a Unix System Administrator
Since then I’ve supported many, many flavors of Unix. A roughly chronological order goes like so:
- Altos 68000, Unix System III. The bourne shell and DACL (Diable Application Compiler Language).
- SCO Xenix, then SCO Unix, back when “SCO” meant the “Santa Cruz Operation” rather than the current SCO crew.
- Hewlett-Packard ‘apollo’ workstations, then 715′s, 725′s, and their ilk.
- RedHat Linux (starting with 4.2).
- Hewlett-Packard servers. HP-UX 10.20, 11.0, 11.11 (11i). From K-class up to and including Superdome and everything in between.
- All of Sun’s hardware and Solaris up to 2.9. Solaris 10 hasn’t been installed in the datacenter enough to speak of.
- The environment I work in now is big IBM and AIX, so now I’m learning that too, though I’m nowhere near as expert in AIX as I am in HP-UX or Solaris.
Why am I telling you this, Dear Reader?
First, NixMe is one of my categories see the category post.
Second, this particular post, assuming some of its readers are kindred *nix spirits, is intended to be a repository for questions about *nix. If I can answer, I will. If I can’t I’ll tell you why.
