From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It wasn't too early, maybe 1997.
I was like 12 or so and I had just installed Linux.
I figured out, from the book I was working with, how to get my windows partition to automaticallyount at boot. Awesome!
I had not been able to figure out how to start "x" though.
So I rebooted into Windows, for on EFnet #linux, and asked around.
Got a command, wrote it down on a slip of paper, and rebooted into Linux.
I should mention, I also hadn't figured out about privileges, or at least why you wouldn't want to run around as root.
Anyway, I started typing in the command that I wrote down:
rm -rf /.I don't have to tell you all, that is not the correct command. The correct command was
startx.After I figured it was taking way too long, I decided to look up what the command does, and then immediately shut down the system.
It was far too late.
My pranks were less destructive ...
/ctcp nick +++ath0+++... it was amazing how often that worked. 🤣PRESS ALT+F4 for ops! 😂
OMG… the showmanship…
Thats a new one on me. What did that do if I may ask? Best I have been able to figure out is that it's probably IRC related but that's it.
Explained nicely here: https://everything2.com/title/%252B%252B%252BATH0
Wow, a post from 2001 that's still online today. You don't see that often any more!
+++ath0is a command that tells a dial up modem to disconnect. I've never seen it used in IRC this way, but my guess is that the modem would see this coming from the computer and disconnect.This was back in the days when everything was unencrypted.
Yes, and encryption had nothing to do with it (though I suppose it would have prevented it in this case).
A properly configured modem would ignore this coming from the Internet side, or escape the characters so that they didn't form that string.
Encryption would prevent it - that's what I meant :)
I think the trick is to convince someone to send that string, so the modem sees it coming from the computer. Similar to tricking someone into pressing Alt+F4, or Ctrl+Alt+Del twice on Windows 9x (instantly reboots without prompting).
encryption would prevent the modem from seeing it when someone sends it, but such a short string will inevitably appear once in a while in ciphertext too. so, it would actually make it disconnect at random times instead :)
(edit: actually at seven bytes i guess it would only occur once in every 72PB on average...)
That’s terrible! They helped me fix my system when I decided I was fancy enough to try building a new version of gcc and go off-script a bit.
IIRC I deleted library.so rather that overwriting it. If I hadn’t been running IRC on another terminal already I would have been done for.
