QUESTION
I have been learning buffer overflows and i am trying to execute the following command through shellcode /bin/nc -e /bin/sh -nvlp 4455. Here is my assembly code:
ANSWER
Answered 2021-Dec-29 at 14:12As you can see in strace, the execve command executes as:
execve("/bin//nc", ["/bin//nc", "/bin//nc-e //bin/bash -nvlp 4455"], NULL) = 0
It seems to be taking the whole /bin//nc-e //bin/bash -nvlp 4455 as a single argument and thus thinks it's a hostname. In order to get around that, the three argv[] needed for execve() is pushed seperately.
argv[]=["/bin/nc", "-e/bin/bash", "-nvlp4455"]
These arguments are each pushed into edx, ecx, and ebx. since ebx needs to be /bin/nc, which was already done in the original code. we just needed to push 2nd and 3rd argv[] into ecx and edx and push it into stack. After that we just copy the whole stack into ecx, and then xor edx,edx to set edx as NULL.
Here is the correct solution:
QUESTION
I am working on my hobby project for creating a theme for lightdm webkit2. I have choosen react framework since I am very comfortable with it. Here is the repo link https://github.com/gitneeraj/reactive/tree/feature/dist (checkout branch feature/dist). With some adjustments(mentioned below), I can get to see the HTML loaded fine as greeter on Display Manager. My problem is when I got a route that has images in the page, then those images does not load even if I have it bundled in. Same applies for any custom font files. Below are the steps to reproduce the issue -
Before you start, make sure you are testing this on a virtual machine. I recommend Arch Linux(because thats what I use) with lightdm and lightdm-webkit2-greeter packages installed and confirgured correctly.
- clone the repo git@github.com:gitneeraj/reactive.git
- checkout to branch feature/dist and
npm ito install deps npm startto see all works fine on browsernpm run buildto build the bundle. This will spit out reactive directory- Manually copy the built reactive folder into /usr/share/lightdm-webkit/themes folder
- Manually update the /etc/lightdm/lightdm-webkit2-greeter.conf file's
webkit_themevariable to theme namereactive. Like so,webkit_theme = reactive - log out/off of your current session and you should see the theme.
- Click on little cog at the bottom and it should take you to DM's list page with images and text. But images wont load.
ANSWER
Answered 2021-May-15 at 15:31I have found solution for this as its related to how you build your project for production. Keeping in mind that Linux treats slash (/) as root, we need to use absolute path from where the theme will be installed to.
QUESTION
I'm using manjaro-linux-i3 with polybar and I'm currently working on my multiple monitor setup. I have a TV which I normally use with the amplifier it is connected to. In addition I have my desk with a triple monitor setup which I normally use with my headphones for audio output. One of my screens is in portrait orientation which always messes up my login screen.
I'm able to change my audio ouput and my active monitor as I wish. But I want it to be more efficient. At the moment I'm using arandr to change my monitor and pavucontrol to change my audio output when needed.
I want that my login manager(lightdm) is always displayed correctly on my monitors(even on the portrait one). It would be nice if anybody could give me way how to combine changing monitors and the audio output in one blow. So that I don't have to this every time manually.
...ANSWER
Answered 2021-Apr-27 at 14:00I have similar setup and I got everything working what you might want if I understood you corretely.
If you setup everything right, then your loginmanager should always be displayed on the monitor which is active at boot and you can switch your monitors&sink with a simple keybind.
First, you can add a script to lightdm to config your monitors so that everything is displayed correctely. But be aware that a broken script can leed to the effect that your loginmanager won't be loaded correctly (blackscrren).
in /etc/lightdm/lightdm.conf you can define a script at #greeter-setup-script= . Simply uncomment the line and add the path to your script.
An easy way to config your monitors the way you want is to use arandr. Simply config your monitor the ways you want and save the setup. You will be saving an usual xrandr command, which can be used in your script.
Here is my script. It is very basic and actually only checks if a monitor of my desk is active. If so, it initialises the monitors of my desk. If not, it initialises my tv. It also sets the audio output I use with those monitors.
To get a list of all active monitors use this command:
xrandr --listactivemonitors | awk '!/Monitors/ {print $4}'
To get a list off all sinks(audio output) use this command:
pacmd list-sinks | grep -e 'name:' -e 'index:' | awk '{print $2}'| awk '{print substr($0, 2, length($0) - 2)}'
Now you can change my commands (sink and monitor names) with the onces you need. You can execute the script in the terminal so get feedback of the choosen sink and monitor (for testing). Don't forget to make your script executable else it won't work.
I got a similar script to manually change between my tv and my desk (mirroring scrrens, duplicate, tv-only, ect)
It too changes the sink according to the selected monitors. As you are using polybar too, you might notice that I relaunch polybar with sh /home/lluks/.config/polybar/launch.sh This is the script.
It ensures that my applets are displayed on the main monitor as poylbar can only display them on one monitor. This is archieved by using a 2 diffrent bars for poylbar.
For this script to work, you need dmenu and rofi. If I remember corretely, you also need Font Awesome for the icons.
QUESTION
Installed Ubuntu Studio 20.04 on an ASUS PN50 mini-PC with Ryzen 7 4800. Upgraded to 20.04.2, kernel 5.8.0-44-lowlatency. Memory 32 GB 3200 MHz. Installation itself was smooth. The box only runs Radeon graphics. There is no NVIDIA. The desktop is Xfce 4.14.
I may be mixing apples and oranges, but since I can't tell (I'm not a hw freak) I'll report more than one issue. They may or may not be related, please bear with me.
Prelude: After installation the system didn't seem to boot. Stuck with Ubuntu splash screen.
On closer look lightdm wouldn't start. This fact kept the system waiting indefinitely.
I modified /etc/default/grub, deleted "quiet splash", added "nomodeset". The system now boots to text. After logging in I do a manual "startx" and the box generally seems to behave well. Graphics look good, snappy response. Later I added "amdgpu.exp_hw_support=1" to grub, but I haven't noticed any difference. The gpumanager log ends with "Nothing to do".
I'm not sure what lightdm does, but it is the default display manager:
/etc/X11/default-display-manager: /usr/sbin/lightdm
Here is systemctl status lightdm.service output. I'm not sure what it's telling me.
ANSWER
Answered 2021-Mar-17 at 08:34After two days of lightdm crash course, here is the answer, and it has nothing to do with Ryzen.
One file was missing from the lightdm configuration. This is an installation from scratch, so either it's missing from the Ubuntu Studio distribution, or maybe I unwittingly deleted it myself somehow.
The file is: /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf:

I am trying to start slurmd.service using below commands but it is not successful permanently. I will be grateful if you could help me to resolve this issue!
...ANSWER
Answered 2020-Oct-06 at 11:16The log files states that it cannot bind to the standard slurmd port 6818, because there is something else using this address already.
Do you have another slurmd running on this node? Or something else listening there? Try netstat -tulpen | grep 6818 to see what is using the address.
QUESTION
I am creating a custom LightDM-Greeter using docs provided by conical. The problem is that these docs do not specify the linking procedure of the lightdm library.
I am running Arch Linux x86_64. On querying using pkg-config --cflags --libs lightdm I get no results, Package lightdm was not found in the pkg-config search path to be specific.
So, do I need to build the src and then statically link to the objects, or is there a way to dynamically link to something like lightdm.so.
I installed lightdm using pacman -S lightdm.
ANSWER
Answered 2020-Sep-20 at 08:47Perhaps pkg-config --libs --cflags liblightdm-gobject-1?
QUESTION
I am trying to add an extra headless seat/session to allow LightDM to offer a headless login page for VNC users without interfering with the person using the desktop. I tried several configurations (with no discernible errors in the logs) similar to the following tutorials for an nVidia card and another adapter:
https://wiki.archlinux.org/index.php/Xorg_multiseat
https://wiki.ubuntu.com/MultiseatTeam/Instructions
However, so far the newer systemd related Xorg configuration process ignores the Xorg "dummy" driver in the examples (for a detached VNC desktop under a separate user login). Notably, the lightDM settings are loaded for the detected nVidia [Seat:card0] setup, but as the [Seat:seat4] is never polled by loginctl it's conf is never applied in LightDM.
...ANSWER
Answered 2020-Jun-17 at 20:36I worked around the issue by using the power switch with a new seat udev rule: TAG=="seat", ENV{ID_FOR_SEAT}=="input-acpi-LNXPWRBN_00", ENV{ID_SEAT}="seat-9",TAG+="master-of-seat"

I'm using Python 3.7.4 and still it shows the same.
UPDATED:

ANSWER
Answered 2020-Apr-21 at 05:58I tried aliasing python:
alias python=python3
And this worked for me as I was running it outside virtual env which caused errors and the default python is 2.7 which is standard.
