re: Leswika@SA (16 Feb 2011, 05:15)
is there a site where i can practice Linux online
Actually, you can telnet to sdf.lonestar.org and get a free shell account,
by taking your time, and READING the help files and tutorials you are
presented with along the way, it will give you a real feel of the 'unix'
Like anything else, you get out of it what you put into it.

Distro's like Ubuntu, while they may be popular do a great disservice
(IMHO) by obfuscating the whole root account they impose on new users by
hiding root, in a manner of speaking, and giving only the su or sudo
options- another topic within itself.......
If I could suggest something, to really LEARN the command line interface in
linux, use a distro that will let you boot directly to the CLI at terminal
1 (tty1) and will let you log in as root, as Bob is trying to show you here
- and you will appreciate and experience the awesom power of having 6
terminals - true multiuser and multitasking!.
Slackware and slack based distros stay very close to this classic unix
approach, and a really good way to get started would be with a slack based
live CD, and boot to 'text mode', (CLI) There, you can learn these basics
Bob is setting forth, AND you can do so as root without fear of causing any
damage, as when you are using a Live CD the file system will be running
entirely in memory anyway - even if you screw something up, no harm no foul
as the whole system is gone anyway when you reboot. Live CD's that come to
mind that are slack based that are very good are slax, NimbleX, Wolvix,
Zenwalk, and Vector Linux. Download the .iso's and burn the CD and boot the
CD. Some even have installers if you wish to install. Also, earlier
versions of slackware itself, I think up to version 9.1 have a live CD
included with the distro. You don't need a bleeding edge whiz bang flashy
distro to learn the basics.

The symbol $ represents that he is an user
whereas # represents the super user
Am I correct?
(17 Nov 2011, 16:15
I'm guessing you have the answer by now, but if others experience this
issue... Ubuntu's root user is disabled by default, you cannot log in as
If you wish to use the root account, you must manually set a password by
opening a shell and typing passwd root and setting the password.
Once a password is set, you can begin using the account, however you should
really read ubuntu's justification for disabling the root user in the first
place before deciding if you want to go that route.

chintan you may find a solution embedded in the following command.
This should explain more about the sudo file. You will especially need to
pay attention to how to limit user access to root in the sudo file.
USERS sudo PASSWORD
You can establish that anyone in the USERS group needs to input a PASSWORD
prior to using sudo. This is helpful because of utilities like fam, acct
which track and log goings on in the computer. As root you could set up a
simple script to alert you of users attempting to hijack you. In fact, you
could also set up the script to deny them further access, direct them to a
honey pot or jail. If this all sounds kooky, try using Google a bit and
you'll find out more. HTH.

Hello Bob, I was wondering if you would have a hint for my problem.
I've ucLinux running on my board. After it boots my shell script are
starting automatically in background with logged output. Is it actually
possible to redirect its input and output streams to the telnet console,
which can be create some time later?
I hope you understand what I mean.
Thank you in advance!

i am newbie to linux, can u please let me know how to install linux on
windows 7 as other operating system?
(02 May 2011, 12:42
Thanks for the quick reply Bob. Problem is it didn't work. When the login
box comes up I click other and type root for user name, hit enter and the
box for password comes up but the user name still says other and pressing
enter with the password box empty still gets me Authentication Failure.
(02 May 2011, 12:19
@Wayne - just press ENTER. If there is no root paswword, that should work.

Love your newsletter and am enjoying this tutorial but I have a problem.
When I installed Ubuntu on my Windows machine I set a password for my user
name but not for ROOT. Now when I try to log on as ROOT I get
authentication failed. I only set the one password and it doesn't work.

To answer tb01:
If you log in only to the shell, it IS true, but, if you log into a GUI
(graphical user interface, such as gnome, openbox, kde, etc.), you can open
terminals in a terminal emulator program, as many as you like, some with
tabs (like a browser), but, alt+F# keybinding are likely to be assigned to
other functions (for instance, alt+f2 opens a command prompt in many guis,
like the "run command" thingy in windows).

@Leswika - Every spammer would like that. But if you want to try, download
a live cd (e.g. Ubuntu), burn it and try it out without installing

@tb01 - See the comment by AmbDawn below.

...quote "By default, your Linux system already has a bunch of virtual
consoles waiting in the wings when you start your system, and pressing
alt-Fn at any time will bring the nth one up on your screen. You can also
cycle through the consoles with [em]alt-left arrow or alt-right
Hey Bob, is this still correct in 2011? Same as 'back' and 'forward' in
browsers? If so, is this function limited to terminal logins w/o an
X-window manager? Just want to clarify... Thanks in advance!
Thank you also for this wonderful resource! Finally, a place I can refer
non-geeks for info on Linux!

Firstly, I am really thankfull for the tutorials you provide us.
I had a question, you say log in as root but I read somewhere that for
ubuntu the root is locked permanently and if you want to have privileges of
a root you just have to add sudo in front of the command.
now here is my issue
So in a ubuntu terminal I changed the root pw:
$ sudo passwd
So now I have a changed root pw, but when I do a:
I am prompted for a password, but when I do a:
$ sudo su
I gain access to root privileges without being prompted for a password. My
concern here is that if someone pawns my machine (through my non-root user
account) wouldn't they also be able to sudu su to root privileges without
entering a password?

@zedadex - in Ubuntu you need to use the combination
ctrl+Alt+<F1-F6>. To return to GUI use ctrl+Alt+F7. Hope it helps.

umm... my alt+function keys don't bring up any alternate virtual console
log-in screens or anything. Do you have to press alt+f2 while logging in or
