I was working for a VAR that used Xenix and later SCO Unix and AT&T Unix (NCR Towers). Somehow I ran across some GNU tools. I got a tape of some GNU utilities. In any case I had become familiar with GNU. I started to hear about Usenet and wanted to get on the internet. I got a prodigy account and subscribed to some Unix newsgroups. Somewhere I saw reference to Slackware. By that time I was using a local ISP that has a limit on how long you could stay connected but unlimited from midnight to 8 in the morning. I started a diskette downloading at midnight every night for a couple of weeks to download all the diskettes.
I had a 386sx system cobbled together from parts. I installed and was impressed that I had an actual running unix like system. I played around with it for a couple of years. In January 1996 I started a local ISP/Web hosting and web development company. Not sure if I trusted Linux for production I bought two servers. On one I installed the commercial BSDI Unix system and on the other I install Red Hat 1.0.1 I believe. I set them up in identical configurations (as much as possible). As we grew and added servers it was all Linux. We ended up hosting hundreds of web sites and thousands of email accounts. I started taking old PCs and installing Red Hat along with Linuxconf (not the crappy version that came with some versions of Red Hat, but downloaded and updated from the maintainer). I set these up for most of my local business customers running their own email/proxy/NAT gateway they could self manage with the Linuxconf web interface.
I was all in with Linux in every part of my job until 2001 I was offered a job by one of my customers. The hiring manager told me they were 100% Microsoft and would never use any Unix or Linux or anything else. The offer was too good financially to turn down so I took it. Since that time I have continued to use Linux almost exclusively at home and hobby projects. It has been amazing to see Linux grow in use and acceptance and a shame that I have been prevented from using it for work. I have managed to implement a couple of Linux based proxies here but in general the IT staff is anti-Linux just based on the historical culture.
