I am trying to run a CentOS 8 server through VirtualBox (6.1.30) (Vagrant), which worked just fine yesterday for me, but today I tried running a sudo yum update. I keep getting this error for some reason:

We have a test environment on a public site. There we use --disable-web-security flag on chrome for the testers to bypass CORS errors for public service calls during manual test phase. And also we have localhost requests on the agent machine. However today with Chrome 98 update we started struggling with the network requests targeting localhost.

The error we get is for the localhost requests from a public site:
Access to XMLHttpRequest at 'https://localhost:3030/static/first.qjson' from origin 'https://....com' has been blocked by CORS policy: Request had no target IP address space, yet the resource is in address space `local`.

The site on localhost is configured to return Access-Control-Allow-* CORS headers including "Access-Control-Allow-Private-Network: true".

And also I do not see any preflight request. Just one GET request with CORS error on it.

We suspect this might be a side effect caused when you disable web security by --disable-web-security. It might be preventing obtaining of the target IP address space. Our assumption is based on the CORS preflight section on https://wicg.github.io/private-network-access/

3.1.2. CORS preflight
The HTTP fetch algorithm should be adjusted to ensure that a preflight is triggered for all private network requests initiated from secure contexts.

The main issue here is again that the response’s IP address space is not known until a connection is obtained in HTTP-network fetch, which is layered under CORS-preflight fetch.

So does anyone know any workaround for Private Network Access with --disable-web-security flag ? Or maybe we are missing something. Thanks for the help.

I'm following the Sort Model documentation (https://material-ui.com/components/data-grid/sorting/#basic-sorting) and am using sortModel and onSortModelChange exactly as used in the documentation. However, I'm getting an infinite loop immediately after loading the page (I can tell this based on the console.log).

What I've tried:

• Using useCallback within the onSortChange prop
• Using server side sorting (https://material-ui.com/components/data-grid/sorting/#server-side-sorting)
• Using if (sortModel !== model) setSortModel(model) within the onSortChange function.

I always end up with the same issue. I'm using Blitz.js.

Question in short

I have migrated my project from Django 2.2 to Django 3.2, and now I want to start using the possibility for asynchronous views. I have created an async view, setup asgi configuration, and run gunicorn with a Uvicorn worker. When swarming this server with 10 users concurrently, they are served synchronously. What do I need to configure in order to serve 10 concurrent users an async view?

Question in detail

This is what I did so far in my local environment:

• I am working with Django 3.2.10 and Python 3.9.
• I have installed gunicorn and uvicorn through pip
• I have created an asgi.py file with the following contents

I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10):

encountered RSA key, expected OPENSSH key

Executing the same command from the system shell (using the same private key of course) works perfectly fine.

On the remote server I discovered in /var/log/secure that when SSH connection and commands are issued from the source server with Python (using Paramiko) sshd complains about unsupported public key algorithm:

userauth_pubkey: unsupported public key algorithm: rsa-sha2-512

Note that target servers with higher RHEL/CentOS like 7.x don't encounter the issue.

It seems like Paramiko picks/offers the wrong algorithm when negotiating with the remote server when on the contrary SSH shell performs the negotiation properly in the context of this "old" target server. How to get the Python program to work as expected?

We've had a working Ansible AWX instance running on v5.0.0 for over a year, and suddenly all jobs stop working -- no output is rendered. They will start "running" but hang indefinitely without printing out any logging.

The AWX instance is running in a docker compose container setup as defined here: https://github.com/ansible/awx/blob/5.0.0/INSTALL.md#docker-compose

Standard troubleshooting such as restarting of containers, host OS, etc. hasn't helped. No configuration changes in either environment.

Upon debugging an actual playbook command, we observe that the command to run a playbook from the UI is like the below:

ssh-agent sh -c ssh-add /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data && rm -f /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data && ansible-playbook -vvvvv -u ubuntu --become --ask-vault-pass -i /tmp/awx_11021_0fmwm5uz/tmppo7rcdqn -e @/tmp/awx_11021_0fmwm5uz/env/extravars playbook.yml

That's broken down into three commands in sequence:

1. ssh-agent sh -c ssh-add /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data
2. rm -f /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data
3. ansible-playbook -vvvvv -u ubuntu --become --ask-vault-pass -i /tmp/awx_11021_0fmwm5uz/tmppo7rcdqn -e @/tmp/awx_11021_0fmwm5uz/env/extravars playbook.yml

You can see in part 3, the -vvvvv is the debugging argument -- however, the hang is happening on command #1. Which has nothing to do with ansible or AWX specifically, but it's not going to get us much debugging info.

I tried doing an strace to see what is going on, but for reasons given below, it is pretty difficult to follow what it is actually hanging on. I can provide this output if it might help.

So one natural question with command #1 -- what is 'ssh_key_data'?

Well it's what we set up to be the Machine credential in AWX (an SSH key) -- it hasn't changed in a while and it works just fine when used in a direct SSH command. It's also apparently being set up by AWX as a file pipe:

prw------- 1 root root 0 Dec 10 08:29 ssh_key_data

Which starts to explain why it could be potentially hanging (if nothing is being read in from the other side of the pipe).

Running a normal ansible-playbook from command line (and supplying the SSH key in a more normal way) works just fine, so we can still deploy, but only via CLI right now -- it's just AWX that is broken.

So the question then becomes "why now"? And "how to debug"? I have checked the health of awx_postgres, and verified that indeed the Machine credential is present in an expected format (in the main_credential table). I have also verified that can use ssh-agent on the awx_task container without the use of that pipe keyfile. So it really seems to be this piped file that is the problem -- but I haven't been able to glean from any logs where the other side of the pipe (sender) is supposed to be or why they aren't sending the data.

How I can figure out if someone opens my website in windows 11?

I test user agent and when someone opens my website with windows 11 I will get this

"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0"

So technically this says it's windows 10, not 11.

Is there any way to detect this?
