Currently as a part of an assignment I need to implement a reverse shell on a linux system. The system details are -Quote:Linux Kernal Version - 2.6Database - MySQLUsing web-server I could upload a php file which could execute the command on behalf of me. Now, I want to get root access so that I can get access to system's core files.My sample php file -
When I started using Fedora (with Gnome) a week ago, I noticed a key symbol in the system tray, or however you call that in the linux world ;-). I can't remember what it was called, but it appeared after I loaded a program or administrative function that required root privileges. If I understand correctly there's a certain timeout after you put in the root password that allows you to run more than one program with elevated privileges so you don't have to put in the root password all the time. I remember reading somewhere that you can change that timeout. This key symbol basically was a "screw the timeout, i'm done being root".
This key symbol doesn't appear anymore though and I'd really like it back. I'm pretty sure, I didn't do anything to make it go away, as I didn't play around with any security settings.
It was a little tricky to search for this as I can't recall the actual name of this... key thingy..
This is my first thread ever to make on the linux forum, and I just began using linux Ubuntu Lucid for my server. Please bare with me because I think I am questioning such a basic question. How do you give sftp root privilege to user? I've made group "admin" and made 2 users under that group. Trying to upload a file onto a server using SFTP with one of the user and it fails and says "Permission denied."
I gave full sudo/root permission to the group "admin" from /usr/sbin/visudo I mainly use Tranmit4 but I also have filezilla. Or is there a way to run sudo command on either ftp client application?
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 am trying to install google chrome on my computer, it is in a .deb package and I am using dreamlinux. Earlier today I installed a .cbr/.cbz file reader from root, that was also a .deb and it worked just fine. now I go to install google chrome and it says (Blue is my command, and red is the system response):
I checked under my USER GROUPS and Root is still set as root, and I haven't been using it unless I need to install with it to other directories, Should I be using another command to install? or is it a problem that may affect other aspects of my system? ... My biggest concern is not getting google in, I can wait for that ... I just wanna know why ROOT is under the impression it's not a superuser.
I am trying to install openoffice and I get. Note this installation will be done without root privileges. Therefore you will have reduced functionality. Change privileges to root privileges if you want full functionality. I have opened a terminal and su to root with no avail.
I will be installing Natty using the alternative CD.My system has a separate Home partition.Do I need to erase the contents of the Root and Home partition with gparted or similar,prior to the fresh installation of Natty or will the installer take care of all that automatically?
I'm trying to write a script to do the bulk of my work for me. What I want to do is go through a loop and select records based on loop control variable states. Unfortunately the database I have to use is an MS Access MDB file. I've been reading around and found a link to PHP documentation [below]. What I read in this was that if you have PHP on a Windows BOX you already have the ODBC drivers required to make the database connection. If you're on a *nix box you will need unixODBC drivers from openlink[not open source]. But it also goes on to say that this will allow you to connect from a Linux box to an MDB on a Windows box. What I really want to do is connect to the MDB on the local Linux box. Is this possible? PHP Access Database Docs: [URL]
I want to access suse pc from redhat remotely. i need a remote access tool so that i could access my branch Suse operating system pc through Internet. i am getting teamviewer for linux, it is installed properly but not executing.
I was using the latest stable release of Debian, dual-booted alongside Windows Vista, with the GNOME desktop, installed via netinst, trying to build and install a library that I knew and trusted, when suddenly I couldn't open the Root Terminal. I clicked the link (in Applications->Accessories (I think, whatever the top one is)->Root Terminal), and in the taskbar I saw an item that said "Starting Root Terminal". A few seconds later, that went away, but the terminal still wasn't open. I tried the regular user terminal, to see the same thing happen. Unsure of what was happening, I tried restarting my computer, since that's always the first step you should take in computer problems.
When I restarted, GNOME wouldn't start. The screen would flash a bit for a few seconds, then a dialog box would appear over a background of static that said "The greeter application is crashing. Attempting another one...".t would then go back to the DOS-style kernel, wait a second, and then the same thing would happen. After several of that, I would get a blue screen which said something to the effect of "It has been detected that the desktop environment has crashed six times in the past 30 seconds.
Waiting two minutes before trying again." When it did that, I tried logging in as root to assess the problem. I gave it the correct password, but it said that it was an incorrect login. After several tries (to ensure I didn't mistype the password), I logged in as myself. Same problem. I tried the su command, with the correct password, and it said it couldn't authorise it.
After a lengthy conversation with a friend of mine who was very good with computers, he basically summarised that he had no clue, but that his best guess would be a virus. Upon running the Linux installer, I found the Repair option. Not being particularly familiar with Linux, I used it simply to backup my important files onto a flash drive. I then tried running the Install option, in an attempt to simply write over my existing Linux and make it new again. The installer, however, consistently froze up when trying to start the partitioner, on the "Checking disks..." stage. I figured it was a problem with my partition. In my naivete, I simply used the Windows tools to clear that partition... It destroyed GRUB too, so I couldn't run any OS. I figured my computer was pretty well screwed, and at that point just decided to bring it into the shop and have them completely wipe it.
my computer was backed up onto an external hard driven I brought it back, I reinstalled Windows. Upon restart, it said that it was still looking for GRUB, which made no sense to me. After messing around with it a bit, I decided to just reinstall Linux too. To my lack of surprise, that fixed the problem. Both OS' now ran just fine. The first thing I did on Debian was to install the Clam Anti-Virus, which I understood to be one of the best Linux anti-viruses. However, within about 10 hours, got the same problem as originally. I wasn't doing any of the same things, and between the lack of consistency in activities and the fact that I had an anti-virus running,figured it wasn't a virus. Not knowing what to do, I just left it and have been using Windows since.
Users of Lacie's 4L which is used to burn labels for your Lightscribe disks, are required to have the app run with sudo privileges, (the command being: gksudo 4L-gui). On an older version of an Ubuntu install, I had it set up so that it did this automatically, without it, (or me), being asked for a password. I thought it was something I added to the sudoers file, to give 4l-gui automatic authority, but I forgot how i did it.
I adjusted some settings in the desktop settings folder in KDE. I had only one user account on the machine. Next time I rebooted I could not log into KDE (it kept bombing out). I had to log into the console. Finally I managed to create a new account with useradd but this user cannot sudo
My problem is that my home directory is encrypted, so I need a new user with sudo privileges to delete all the kde files and folders in my original users home directory so that I can start with a new KDE setup (which wonï¿½t be a bad thing since I tinkered a lot).
How can I add sudo privileges to the new account (I presume I can do it by logging in with my sudo account in a terminal login?
I have been wondering if a guest user could compromise a machine which is set in the following way: they are not able to open the computer case, to boot from either an USB flash drive or an optical-disc drive, nor have any knowledge of the administrator-user password. Thus, they are landing on their guess account, and have to work their privilege escalation from there.
Therefore, what can they do to gain it? Could they download or otherwise install or run from a thumb drive an application that could be used to crack the administrator-user password? Because, it seems to me, could they enter into the system such a password-cracking application, the whole system could be compromised given the administrator-user password contains less than 9-or-so characters. What do you think? Can I lend my computer to anybody without them having beforehand gained my trust in them? Is the reasoning reasonable?
due to an exercise in Operating Systems I have to do the following: There are 6 users, user1, user2 ... user6 with home directories /users/user1 ... users/user6. User1 to user3 belong to group1, user4 to user6 belong to group2. The System Administrator wants to change the privilege* only to users 1, 2 and 3 to execute the file /bin/xxx. Which are the commands he has to type in order to achieve the previous?*I'm not sure if this is the right translation.What I have come till now is: Code: $ chgrp group1 <name_of_file> but it seems too simple to be right.
I am a Newbie to Server platform. Just installed Ubuntu 9.04 server, As my Lappy not supporting OEL 4. I was shocked to see that there is no GUI. Anyhow, in that it is showing to Login. I enter the Username and password which was created during Installation on Ubuntu server. It was fine. How to goto Root? I typed su - root and entered password Says Authentication failure. How can I overcome this? While Installation where ever it asks for a password I use the same one.
So, my company has a new web-based VPN client. I go to a specified URL, log in, and then a Java widget starts and tries to install some stuff. I get this screen:
It's asking me for my root password. I know how to set the root password, but I want to avoid that and use sudo instead. But as you can see from the image, the install is initiated in such a way as to prevent me from doing anything but entering my root password. And apparently my sudo/admin password isn't the same as my root password, because it doesn't work. And I can't access the executable from any other way. Is logging in as root briefly my only option here?
I recently installed Ubuntu 10.04 32bit on my laptop. I am trying to learn the command line and also install software via the command line. I type in su and hit enter it asks me for my password and I type that in. The password fails, why is this? I am the one who set this up and installed the OS. Now I am logged in using my normal user account when doing this from the GUI
I'm having some problems getting photos off of my camera that I am thinking I can work with if I can access the photos on the camera as superuser. However I don't understand how Ubuntu (gnome) mounts cameras now, they don't show up as a mounted drive and I can't access (or find it at all) with 'sudo nautilus.'
 Oh, also, the camera shows up if using nautilus not as a superuser.
I'm a new comer to Linux world, and I wish I can find help with some difficulties that I might face. I have a machine with Window 7 and Ubuntu (dual boot), windows 7 is installed on C drive and ubuntu installed on D drive, when I'm on Window, I put a folder named folder1 on D drive root beside (not inside) the main ubuntu folder. when I open ubuntu I can't see that file on D drive, I tried to search for it but couldn't find it, how can I access this file please ?
It's been a few years since I last installed Ubuntu. I searched the forums and can't seem to find the answer. I want to be able to do a "su root" and have root access. I know Ubuntu wants you to do the sudo command, and I know you can really mess things up being root. I know I got this to work before. What do I need to do?
I have two users in my system. Admin(Root) , and "student". I am making a bootable USB with Ubuntu 10.04 with two partitions. What i need is a cron-job who copies some files that the student has made(from the first partition) onto a partition which he is not allowed to access. The way i thought it should be done was making a root cron-job which mounts the drive and then copies the documents, and maybe unmounts it again.
The problem with this is that, when i mount it, wouldnt it be accessible to the "student" as well then? Since i give him sudo-rights and mounts the drive in the background for him? Alternatively i could unount it straight after the copying is done, but then it would do this too often I guess.
