Accessing the root@desktopX Directory

RacingFan3139 · 02-15-2016, 11:07 AM

Hello,

I am completely new to Linux and I need some help. I know how to successfully enter into the root directory for the server, however, I am not sure on how the root directory for the desktop. Therefore, what command(s) should I use to access the desktop's root directory?

Thanks in advance,

Welcome to LQ!

Please describe in more detail what you are trying to achieve and why. People new to Linux often do not realize there are number of ways to get job done in Linux, things that are impossible in Windows are possible in Linux. So describing the goal instead of asking how may lead to surprising solutions.

I don't understand the question. What is "desktop's root directory"?

Habitual · 02-15-2016, 11:38 AM

/root/Desktop doesn't exist until root logs in graphically.
Something that is generally discouraged.

Most servers don't have a GUI, generally speaking, so "desktop's root directory" is ambiguous.
And being "completely new to Linux", is a Red Flag.

Why are you asking?
Please elaborate and cite your references.

I am going to take a guess, and assume you mean "How do I log in to the GUI/Window manager as root on the console?"

Short answer is: you don't...it's disabled for VERY GOOD SECURITY REASONS. As you're new to Linux, be aware that you should *NEVER* log in as root (or even ASSUME root with "su -"), unless you have an excellent reason for doing so. Treat the root account like a loaded gun.

Longer answer: you CAN, but how you enable that access depends on the version/distro of Linux and the window manager/login manager you're using. While it CAN be modified, it isn't simple (usually), and that takes you back to "Don't EVER LOG IN AS ROOT"

I apologize about my post. I should have been more clear on my question. I am learning Linux for the first time by taking a course that is provided by the RHA (Red Hat Academy). What I am trying to do, or the goal of this assigned practice, is to configure a host name on the desktop's root file, as seen in the attachment.

Picture Note: In the attachment, I am assuming that the letter X is my foundation number.

As a result, I was wondering how I can access the desktop's root file in the terminal and be able to set the provided host name on the system.

Still doesn't make sense.

Please define a couple of things for me if you would, because I think there's a language problem here:
1) "desktop"
2) "root file"

What distro/version are you using and what have you tried so far?

As general information, hostnames are commonly stored in a file in the /etc directory. The exact name and format of the file(s) in question can vary slight depending on the particular distro.

You might want to take a look at this, if you have not already done so: http://www.linuxquestions.org/linux/...Ask_a_Question

The desktop has nothing to with the hostname. The hostname can be anything but typically is a fully qualified domain name.

The Linux distro/version that I am using in the course is Red Hat Enterprise Linux Server 7.0.

On the other hand, however, I think I figured it out. On the home screen, there are 4 icons: Home, Trash, View Server and View Desktop. I clicked on View Desktop and signed in. After signing in, I right-clicked the home screen, went to Open in Terminal and used the su - command in the terminal to access root. As a result, I believe that I am now able to finish the question I provided earlier.

if you right clicked open terminal here that is just where you are at, the directory is desktop,
cd enter to get back home where you belong.

for hostname

Code:

sudo nano /etc/hostname

enter what hostname you want save then exit

domanname

Code:

 %userx@voided 08:18:34 ~ >>$ sudo cat /etc/hosts
#
# /etc/hosts: static lookup table for host names
#

#<ip-address>		<hostname.domain.org>	<hostname>
127.0.0.1		localhost.localdomain	localhost
::1			localhost.localdomain	localhost ip6-localhost
127.xx.xx.xx            voided.domainName.xxx    voided
# End of file

edit hosts conf

I don't know how legal that is, if you have apache installed it goes in there.

4 red hat I found this

Quote:

Permanent hostname change on RedHat based systems

RedHat based system use the file /etc/sysconfig/network to read the saved hostname at system boot. This is set using the init script /etc/rc.d/rc.sysinit

/etc/sysconfig/network
NETWORKING=yes
HOSTNAME="plain.domainname.com"
GATEWAY="192.168.0.1"
GATEWAYDEV="eth0"
FORWARD_IPV4="yes"

So in order to preserve your change on system reboot edit this file and enter the appropriate name using the HOSTNAME variable.

at desktopx I think is what that said.

would be in that file "Permanent hostname change on RedHat based systems" /etc/sysconfig/network

Code:

HOSTNAME="desktopx.WHATEVERNAME-U-Want-HERE.com, org, net "

where .org .net .com are the common ones,
org = organization ~ non-profit organizations

com = commerce ~ the activity of buying and selling, especially on a large scale

net = network ~ mostly used for ones own server network, domain originally for network providers

domainname(1) - Linux man page

Quote:

Files
/etc/hosts /etc/sysconfig/network
Note
Note that hostname doesn't change anything permanently. After reboot original names from /etc/hosts are used again.
