Cant Enter To Settings (general) On Centos 7

hello everyone.,
i am using linux Centos 6 machine, i have downloaded "back in time" through command line.

i found some commands but that for UBUNTU and not running on Centos 6, giving error.
so , without GUI. can be possible to install and use it?????

thanks in advance..

hello there,
OK here is the problem;
Whenever I try to start my laptop the grub menu loads as usually, it starts booting but upon completion, there is this blinking cursor and screen and then nothing. It started when I logged out of one of my account and logged into Root account and again logged out of the root account. That was the time when this thing started.
I dont know what happened. I researched, found lots of threads but with no help..
There is no any graphics card in the laptop. (so couldnt be a driver issue i think)
Edited the grub ( quite splash nomodeset, etc etc,, but didnt work )
I really dont know what to do at this stage,
P.S i am a noob though.

Just fired up CentOS 6.5 on a brand new Dell laptop and when I go to /etc/sysconfig/network-scripts/ I dont see the ifcfg-eth0 etc. Are those not there because Network Manager is doing the work? I remember working with these a lot in the past. Sorry, I know this is a vague question.

Edit: Also wanted to know about this virbr0 interface, is this because I installed kvm and kvm related packages? Dont remember this being present in the past.

CentOS Linux 7 (core)
Kernel 3.10.0-299.el17.x86_64 on an x86_64
local host login:kd
[kd@localhost ~]$

The above is what displays on a black screen.
The program was d/l to DVD and then installed on a usb stick and booted from there. No password.

This is the second installation. On the first, a pw was specified but at login, it would not accept input from the keyboard except the enter key which resulted in Incorrect Password.

Help would be much appreciated.

I had used CentOS 6.6(desktop) before now install centos 7(desktop) on my pc.
In centOS 6.6 had “Connect to Server” in the Places menu, select “Public FTP” or “FTP (with login)” as the service type, enter the server name and other parameters (you can define bookmarks in this dialog box too),

But I cannot find it on centOS 7.I need to login Ftp via Connect to Server.

Hi all,
i am new to linux, i am using Centos 6. There is some problem in the network settings as i am able to browse internet from a browser but when i am trying to use the terminal (using ping command) for any of the website (say www.google.com) nothing is happening. suppose i want to install some software (like hdf5), when i am using "sudo yum install hdf5" it shows large number of error massages like "error could not connect to the host". It would be a great help if someone provide the solution.
Thanks in advance.

hello all,
i am using linux Centos 6. i am not familiar with webmin.. and dont want to create 'webmin group' manually.
So.., is it possible to create 'webmin group' automatically... i.e from the command line?? what are the commands for that?

Thanks..

hi guys,

i want to back up my centos server that has a few virtual machines on it...i read that some people were saying dd is a very good way to do this. but a lot of people dont cause of fear of the command line.

i would like to write a script that backus up the entire hard drive to a ext usb hard drive.

i have a couple of questions though.

1) am i better off using a cloning software like acronis or storage craft.

2) can dd also restore a system to a bootable state or is it really just a backup.

3) can you still use the system while it is backing up?

thanks...

Hi all,

Been reading on stdin, stdout and stderr and encounter 2 questions, hope gurus here can advise.

0 = stdin
1 = stdout
2 = stderr

Code:

Sun Dec 21 03:53:42 SGT 2014 > cat test5.sh
#!/bin/bash

echo "Please enter value for name :"
read name
echo "Your name is $name."

echo "Next echo will be a syntax error"
ehco

Code:

Sun Dec 21 03:53:46 SGT 2014 > test5.sh 1> output.txt 2> error.txt
Noob

Sun Dec 21 03:54:56 SGT 2014 > cat output.txt
Please enter value for name :
Your name is Noob.
Next echo will be a syntax error

Sun Dec 21 03:55:23 SGT 2014 > cat error.txt
/home/alan/scripts/test5.sh: line 8: ehco: command not found
Sun Dec 21 03:55:26 SGT 2014 >

Which so far all is good and the correct way to output everything including error to a single file is

Code:

Sun Dec 21 03:59:14 SGT 2014 > test5.sh > output.txt 2>&1

Q1) How is a command being interpreted in linux , the sequence in which it is interpreted ? from left to right ? right to left ?

Shouldn't it be

Code:

test5.sh 2>&1 1>output.txt 
or 
test5.sh 2>&1>output.txt ?

Regards,
Noob
