View 4 Replies View RelatedI'm trying to use this tutorial (URL...) to backup my Ubuntu 10.10 (ext3) operating system. I've successfully gotten it into a TAR file on my external hard-drive, but inside the archive are 2 folders: sda5 and media (/media/sda5/), sda5 ofcourse containing my operating system.
I run VMWare as my virtual machine software, but I could easily run Virtual Box if the situation calls for it. On my virtual machine I created an Extended partition, made a 2GB swap space and the rest is ext3 (ext3 space is mounted as sda1) (at this point, Swap is OFF) here is what I've tried to do inside the virtual machine to restore:
Code:
sudo -s
mkdir /media/FROM/
mkdir /media/TO/
mount /dev/sdb1 /media/FROM/
[Code]...
but instead it just creates the directory sda5 under media of the live ubuntu cd Do I need to CHRoot in these conditions? AFTER I get the files successfully into the virtual machine, how do I go about restoring the grub2 bootloader? Right now I haven't tried to restore grub on my hardware, but I would be interested in doing so. There are a vast immense amount of forum posts about this subject, but all are to mixed results. Can anybody tell me the absolute definite way to restore grub2 successfully, I don't want to try something if it's going to mess up my install, whether I've backed up or not.
for further reference, here is a link to the previous (failed) thread I made about this same subject:

My application is installed on root of RH enterprise 5 and is run via user on the same machine. This need ssh without password from the user.
i do the following :
1. run ssh-keygen in .ssh directory of the user.
2. copy the id_rsa.pub as the authorized-keys in the root's .ssh directory
3 chmod 600 to the authorized_keys
4.restart the machine
5. login from the user and ssh SER ( SER is the entry in the /etc/hosts with the ip address of the machine)

How can i ssh from the user to the machine without password.
I just did a net install of Debian Jessie in VMWare Player. I very much enjoyed the install. I chose not to install a desktop. I set the root password as root. And the user as paul/paul. Now I cant login in root, it says I have the wrong password. How would you resolve this?

I'm new to Linux (had some basic Unix experience in 1995 era). (Teenager) gave me HP2133 mini notebook running SUSE Linux Enterprise Desktop 10. Everything checks good (hardware and software), even wireless networking. Problem is she apparently created Admin/root password but says cannot remember. I cannot even set correct date time... yast is asking for root privilege:
Command: /sbin/yast2 time
Is there anything I can do to re-establish administrator privilege?
I recently installed vsftpd on my server. I noticed that users on the machine can login into vsftpd with their username and password on the machine and go to their root dir "/home/username".Now, I want to give some people a vsftpd username and password so they can upload and download files and folders to their folder, but this folder has to be in the "/var/www/(username)" folder. I don't want them to be able to go to any other folder than their own folder like "/var", "/etc" or "/home" etc. Also I don't want them to be able to login on the machine as a user, through putty for example. They should only be allowed to acces their folder with vsftpd, nothing else.
View 1 Replies View RelatedYesterday, when I was installing Redhat Enterprise 5.4 on a HP server, I asked myself "how can I regain my access to the server if I happen to forget the root password?" I knew there must be a way. I consulted with my friend "Google". I'd like to share it here as my 1st post (too bad that I'm not allowed to paste screenshots)
1) Boot up the server, when you are at the "Red Hat Enterprise Linux Server..." entry, press "e".
2) Highlight the "kernel /vmlinuz...." line then press "e" again.
3) Type the word "single" to the end of the line (with an empty space before the word single). Press Enter.
4) Press "b"
5) System will boot. When you get the prompt "#", type "passwd" to enter in new password for root.
6) Reboot the system. Done

View 3 Replies View RelatedHaving installed Debian 7 on an old machine from a Liinux Format Magazine DVD I was unable to log in as a specific user. I can login as root and use useradd etc but when I logout of root I still cannot login as a user and nor will the machine accept my root password. I have to shutdown and reboot to get back into root. I'm using O'Reilly's Linux Pocket Guide from 2004 for the commands. Could it be that things have changed?

View 6 Replies View RelatedI am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?
View 1 Replies View RelatedI was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?
