-The operating system was a **Windows 98** [[12]](https://en.wikipedia.org/wiki/Windows_98) full of bugs. Mauro hack my desktop in a couple of weeks with a **MS-DOS** [[13]](https://en.wikipedia.org/wiki/MS-DOS) trick in the classic **AUTOEXEC.BAT** [[14]](https://en.wikipedia.org/wiki/AUTOEXEC.BAT) script. So I start to hack. At that time, more then twenty years ago, I use to play. I start gaming, **IRCNet** [[15]](https://en.wikipedia.org/wiki/IRCnet), **takeover** [[16]](https://en.wikipedia.org/wiki/IRC_takeover), **Stacheldraht** [[17]](https://en.wikipedia.org/wiki/Stacheldraht), **Eggdrop** [[18]](https://en.wikipedia.org/wiki/Eggdrop), **BNC** [[19]](https://en.wikipedia.org/wiki/BNC_(software)), **Shell** [[20]](https://en.wikipedia.org/wiki/Shell_(computing)), **TESO team** [[21]](https://en.wikipedia.org/wiki/TESO_(Austrian_hacker_group)), **Smurf** [[22]](https://en.wikipedia.org/wiki/Smurf_attack) and so on. This is how I start to play with Unix, only illegal hacking in the ninety.

-**Unset HISTFILE** [[23]](https://www.gnu.org/software/bash/manual/html_node/Bash-History-Facilities.html) was my preferred command. We found a crew in IRCNet. We started a shell provider and started to sell bouncer to the IRC network. We were testers of IPv6 and **3FFE class** [[24]](https://en.wikipedia.org/wiki/6bone). We started learning **apache** [[25]](https://en.wikipedia.org/wiki/Apache_HTTP_Server), **FreeBSD** [[26]](https://en.wikipedia.org/wiki/FreeBSD), **POLLING** [[27]](https://www.freebsd.org/cgi/man.cgi?query=polling&sektion=4&n=1), **kernel hacking** [[28]](https://www.freebsd.org/doc/en/books/arch-handbook/), networking, user administration, IPsec, **BIND** [[29]](https://en.wikipedia.org/wiki/BIND), and so on. Slowly I joined Unix and networking community.
