I'm creating an api in node. with an endpoint that returns devices connected to my wifi using the function find of local-devices dependency. locally it works fine and it brings me the data correctly. but when I deploy my api I receive an error related to command
arp -an with the following info:
{"code":127,"killed":false,"signal":null,"cmd":"arp -an"}
I have already tried to connect to the deployed vm and install net tools but it didn't work
PD: I already try to create my own function with arp and it gave me the same error

NPM used to work no problem but now for some reason anything I try to do that involves connecting to the registry times out.
The failure message I get from NPM is request to https://registry.npmjs.org/corepack failed, reason: connect EHOSTUNREACH 2606:4700::6810:1223:443
The command I'm running is npm update -g.
I'm on Arch Linux, and I installed the NPM package from arch. It is version 8.19.2 (the latest on arch).
I tried two DNS, the one I'm using now is Cloudflare (1.1.1.1).
Pinging "registry.npmjs.org" results in From 2600:1700:4630:c000::1 (2600:1700:4630:c000::1) icmp_seq=1 Destination unreachable: Address unreachable
But if I go to registry.npmjs.org in my web browser, I get the expected json result.
Any help is appreciated.
https://askubuntu.com/questions/32298/prefer-a-ipv4-dns-lookups-before-aaaaipv6-lookups/38468#38468
For some reason ipv6 requests are not working on my current network. I "solved" the issue for now by preferring ipv4 using the solution in the link above. Ultimately I'd like to find out why ipv6 is not working on my computer/network but for now this is fine.
I am attempting to get a mobile app to run using expo and whenever I run the simulator I get the following error.
One of the recommended solutions is to set the URL correctly in AppDelegate, and I have already tried to find this file and look at solutions on the web but I cannot even find the AppDelegate.m file to do this.
Do you know where it is and how I could update the file to fix my code?
Thank you!
Could not connect to development server.
Ensure the following:
- Node server is running and available on the same network - run 'npm start' from react-native root
- Node server URL is correctly set in AppDelegate
- WiFi is enabled and connected to the same network as the Node Server

I have created a new react native project by running "react-native init MyFirstProject". I have also installed node and have added no code of my own to any of the files.
I have tried to run the project to make sure it works by running "react-native run-ios --simulator="iPhone 8"". The command runs successfully but I am given the following error.

How do I fix this error?
Try opening your project ios/MyFirstProject/MyFirstProject.xcworkspace and see if there's any build error.
I ran into this problem too, with the same error:
RCTFatal __28-[RCTCxxBridge handleError:]_block_invoke
It turned out that I had another server running on my local machine on the same port that the expo development client server was running (:8081), and that it was taking priority and then obviously giving the client a very different response to what it was expecting. Quitting the other server fixed the problem.
I have been setting up a server on a Digital Ocean droplet in order to host a couple of Meteor apps. I'm doing everything from scratch so I can learn as much as possible. I am trying to use "Meteor-Up" (mup) to deploy an app, but it is having problem communicating with MongoDB. When I run "mup setup" I get the following error:

But I can't get from this any indication of what's going wrong. Is the problem with Mongo, Meteor, mup, or docker?
EDIT:
So far I understand from the message that "mup" is trying to connect to Mongo on port 27017 and is failing, I just don't understand why or how to fix it. I have a database that I want the app to connect to, which I moved onto the server from my local machine using mongodump and mongorestore. The thing I can't solve is how to connect my meteor app to that mongo DB.
It does not just try to connect to mongod, but it installs mongod in a container and tries to bind port 27017 to local interface.
If you already have mongodb installed and prefer to use it instead, you need to disable installation of mongodb in mup.js, mup.json, or whatever configuration file is being used in your version of mup.
I followed the steps mentioned in following documents and everything runs perfectly.

Now am trying to run the android app on my device but I get below error.
I tried following to resolve the issue:
react-native start > /dev/null 2>&1 &
adb reverse tcp:8081 tcp:8081
If I try to run without a server, bundle the jsfile into the apk by running:
curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"
I get
I followed all the steps outlined in this question react native android failed to load JS bundle but still I am not able to resolve the issue.
I am using my smartphone's data plan on my OSX machine via hotspot. I entered my machine's IP address inet 192.168.43.14 along with port 8081 in the react-native developer setting.
Any idea what am missing here?
