Issues running commands via cloud-init

Asked 2022-Mar-22 at 02:11

An open source project I'm working on has components that require Linux and consequently virtualization has generally been the best solution for development and testing new features. I'm attempting to provide a simple cloud-init file for Multipass that will configure the VM with our code by pulling our files from Git and setting them up in the VM automatically. However, even though extra time elapsed for launch seems to indicate the process is being run, no files seem to actually be saved to the home directory, even for simpler cases, i.e.

QUESTION

Getting corrupted output when using NVENCODE API

Asked 2022-Feb-10 at 08:44

I’m trying to use the NVENC API (specifically the AppEncode application) available as part of Video Codec SDK 11.1.5 to encode a yuv video (saved from IMX490 sensor) using H.264 encoding.

After building the required libraries using CMake, I give the following command:

./AppEncCuda -i ~/Desktop/input-yuv420p.yuv -s 320x320 -tuninginfo lowlatency -rc cbr -gpu 0 -bitrate 2M -maxbitrate 4M -vbvbufsize 6M -vbvinit 25 -bf 0 -aq 0 -cq 20 -multipass qres -o ~/Desktop/output-yuv.h264

A bit of additional information: input-yuv420p.yuv has pixel format yuyv422(progressive), 2880x1860 All the flags set were based on recommended settings (NVENC Video Encoder API Programming Guide :: NVIDIA Video Codec SDK Documentation)

Hardware used: CUDA 11.4, NVIDIA GeForce RTX 3050 Ti

I also tried the equivalent using ffmpeg (h264_nvenc and h264_cuvid) and it works perfectly. However, when I try to encode just using the NVENC APIs I get corrupted outputs. I have tried converting the pixel format to yuv420p and encode, still doesn’t work. When I try to display by encoded files using VLC media player I get green pixels/lines and random colours.

I’m quite new to using NVENC API so I started right away with the Video SDK but I’m facing these issues. I’m not sure what’s causing it, so any advice would be really helpful!

It was as simple as changing -s 320x320 to -s 2880x1860. -s flag denotes the input resolution size rather than scale (which is what I initially assumed).

Ideally a command like this should work smoothly:

I have created a Virtual Machine with multipass, I am trying to connect to this instance over ssh, with the command:

ssh -vvv -i back_key ubuntu@10.136.38.199

At first, I tried to connect to my instance from a Github Action, but I got a timeout error, I thought that it may have been a Github issue.
But with a second computer, I couldn't connect to the VM either.

The error I got:

ANSWER

Answered 2021-Nov-19 at 22:36

The reason: I got those issues was the network I was working on. The ssh port for the server couldn't be reached.
I knew that by using nmap:

nmap -Pn -p 22

The result was: The port is filtered.
Working with a mobile network didn't solve it either, since my ISP block this port. The solution was using the network from my house for the ssh server.

ANSWER

Answered 2021-Nov-15 at 13:23

You have to create a network bridge to access the VM from outside, using the --network parameter when launching the instance. Then, you can share a folder from the instance using the SMB protocol (installing the samba package on the instance and configuring it in /etc/samba/smb.conf). And you'll see the share on your Finder.

The next step in the investigation paid off. I went through all the packages where a newer version may have been installed by npm install, and found two relevant ones: express-session changed from 1.17.1 to 1.17.2, and session-file-store from 1.4.0 to 1.5.0. Reverting back express-session to 1.17.1 did not help, but reverting back session-file-store to 1.4.0 fixed the problem. Phew! [PS: This text was previously posted as a comment on July 30 at 17:57]

Since your service is Cluster Ip you can not access the service out of Kubernetes cluster.

You have to expose your service as Node port or Loadbalancer.

however, for testing and debugging locally you can use this command :

ECDSA signing/verifiying appears to be only considering the first 32 bytes of the data

Asked 2021-May-15 at 10:43

ec = OpenSSL::PKey::EC.new('secp256k1')
ec.generate_key
signature = ec.dsa_sign_asn1("A" * 64)
refute ec.dsa_verify_asn1("A" * 32, signature) # Fails here

...

ANSWER

Answered 2021-May-15 at 10:43

When signing, not the data itself is signed, but the hash of the data. This is necessary on the one hand to be able to sign longer messages and on the other hand for security reasons (s. here).

For secp256k1 typically a digest with an output size of 256 bit is used (s. here), e.g. SHA256.

If you take a digest with a larger output size, the leftmost n bits of the hash are considered according to NIST FIPS 186-4 (s. here, where n is the key size, i.e. bit size of the generator order, 256 bit for secp256k1).

This is the reason why in the posted example the verification is successful: Only the first 32 bytes are considered, which are identical.

If the hashed value of the data is used instead, the verification fails as expected:
