QUESTION
I am trying to connect my Android 11 device with android studio over adb wifi but it is not working.
I updated to latest stable bumblebee and updated my SDK I tried turning off firewall on my pc but it is same result.
When I use QR code method my android phone just shows "pairing device" and nothing happens If I try the code method, android studio just shows "searching for devices" but nothing happens
and, yes, I enabled wireless debugging on my phone and I am connected to the same wifi network.
I don't know if the problem is with my computer or phone. I do not have any other Android11+ phone to try with
...ANSWER
Answered 2022-Jan-30 at 21:44I was having the same problem as you. Neither pairing by QR nor by pairing code worked.
So I tried connecting by typing adb connect [phone_ip]:[port] in the terminal and that worked flawlessly. Didn't even need to plug the phone to the computer with USB. Your phone will tell you the IP and port right above the "pair with QR code" option inside the Wifi-debugging setting. Just connect to that address.
QUESTION
I am currently trying to connect to an AWS REST API which requires at least TLS v1.2. The documentation stats that clients must also support cipher suites with perfect forward secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE).
When sending a GET request using the HttpClient, the connection simply times out. I have set the TLS version explicitely to TLSv1.2 like this:
ANSWER
Answered 2022-Mar-30 at 12:52We finally found the reason for this. Windows did not have the required cypher suites enabled. We have used IISCrypto to enable the corresponding cypher suites and all is ok now.
It looks like it's possible to force .NET to TLS 1.2, even though it was not enabled on the server itself.
QUESTION
We are getting logs that calls to k8s are being made, despite our cluster being private, as well as being behind the gcp firewall with a rule that blocks all ingress except IAP IPs (and ICMP). What am I missing?
...ANSWER
Answered 2022-Mar-24 at 20:28The private clusters have a control plane private endpoint and a control plane public endpoint and you can choose to disable the control plane public endpoint, this is the highest level of restricted access. So you can manage the cluster with the private endpoint internal IP address with tools like kubectl and any VM that uses the same subnet that your cluster can also access the private endpoint.However, it is important to say that even if you disable the public endpoint access, Google can use the control plane public endpoint for cluster management purposes, such as scheduled maintenance and automatic control plane upgrades. If you need more information about how to create a private cluster with public endpoint disable, you can consult the following public document.
You can review your public endpoints with the following command:
QUESTION
I have seen the question asked here from 2018. I'm wondering if there is a better answer today.
Our work computers are bedeviled by an entire IT security department that seems to exist to make them useless. We are allowed to run R 3.6.3 (4.x hasn't been approved yet). We cannot connect to CRAN from behind the corporate firewall. In the past that meant we took our laptops home to install packages. But now we have a download monitor that blocks CRAN downloads even when we're on our own wi-fi.
I was attempting to get around this by downloading the package .zip files on a personal machine, transferring them via CD, and then installing with repos=NULL. I used this code
...ANSWER
Answered 2022-Feb-09 at 03:33I'm not sure if it completely addresses your needs, but package checkpoint seems appropriate here. It allows you to download source packages from a snapshot of CRAN taken at a specified date, going back to 2014-09-17. R 4.0.0 was released around 2020-04-24, so the snapshot from 2020-04-01 should work for your purposes.
Here is a reproducible example:
QUESTION
I've been trying to get over this but I'm out of ideas for now hence I'm posting the question here.
I'm experimenting with the Oracle Cloud Infrastructure (OCI) and I wanted to create a Kubernetes cluster which exposes some service.
The goal is:
- A running managed Kubernetes cluster (OKE)
- 2 nodes at least
- 1 service that's accessible for external parties
The infra looks the following:
- A VCN for the whole thing
- A private subnet on 10.0.1.0/24
- A public subnet on 10.0.0.0/24
- NAT gateway for the private subnet
- Internet gateway for the public subnet
- Service gateway
- The corresponding security lists for both subnets which I won't share right now unless somebody asks for it
- A containerengine K8S (OKE) cluster in the VCN with public Kubernetes API enabled
- A node pool for the K8S cluster with 2 availability domains and with 2 instances right now. The instances are ARM machines with 1 OCPU and 6GB RAM running Oracle-Linux-7.9-aarch64-2021.12.08-0 images.
- A namespace in the K8S cluster (call it staging for now)
- A deployment which refers to a custom NextJS application serving traffic on port 3000
And now it's the point where I want to expose the service running on port 3000.
I have 2 obvious choices:
- Create a LoadBalancer service in K8S which will spawn a classic Load Balancer in OCI, set up it's listener and set up the backendset referring to the 2 nodes in the cluster, plus it adjusts the subnet security lists to make sure traffic can flow
- Create a Network Load Balancer in OCI and create a NodePort on K8S and manually configure the NLB to the ~same settings as the classic Load Balancer
The first one works perfectly fine but I want to use this cluster with minimal costs so I decided to experiment with option 2, the NLB since it's way cheaper (zero cost).
Long story short, everything works and I can access the NextJS app on the IP of the NLB most of the time but sometimes I couldn't. I decided to look it up what's going on and turned out the NodePort that I exposed in the cluster isn't working how I'd imagine.
The service behind the NodePort is only accessible on the Node that's running the pod in K8S. Assume NodeA is running the service and NodeB is just there chilling. If I try to hit the service on NodeA, everything is fine. But when I try to do the same on NodeB, I don't get a response at all.
That's my problem and I couldn't figure out what could be the issue.
What I've tried so far:
- Switching from ARM machines to AMD ones - no change
- Created a bastion host in the public subnet to test which nodes are responding to requests. Turned out only the node responds that's running the pod.
- Created a regular LoadBalancer in K8S with the same config as the NodePort (in this case OCI will create a classic Load Balancer), that works perfectly
- Tried upgrading to Oracle 8.4 images for the K8S nodes, didn't fix it
- Ran the Node Doctor on the nodes, everything is fine
- Checked the logs of kube-proxy, kube-flannel, core-dns, no error
- Since the cluster consists of 2 nodes, I gave it a try and added one more node and the service was not accessible on the new node either
- Recreated the cluster from scratch
Edit: Some update. I've tried to use a DaemonSet instead of a regular Deployment for the pod to ensure that as a temporary solution, all nodes are running at least one instance of the pod and surprise. The node that was previously not responding to requests on that specific port, it still does not, even though a pod is running on it.
Edit2: Originally I was running the latest K8S version for the cluster (v1.21.5) and I tried downgrading to v1.20.11 and unfortunately the issue is still present.
Edit3: Checked if the NodePort is open on the node that's not responding and it is, at least kube-proxy is listening on it.
...ANSWER
Answered 2022-Jan-31 at 12:06Might not be the ideal fix, but can you try changing the externalTrafficPolicy to Local. This would prevent the health check on the nodes which don't run the application to fail. This way the traffic will only be forwarded to the node where the application is . Setting externalTrafficPolicy to local is also a requirement to preserve source IP of the connection. Also, can you share the health check config for both NLB and LB that you are using. When you change the externalTrafficPolicy, note that the health check for LB would change and the same needs to be applied to NLB.
Edit: Also note that you need a security list/ network security group added to your node subnet/nodepool, which allows traffic on all protocols from the worker node subnet.

I want to know how can we mount an file as read-only in Linux CentOS 7 Server through Golang. I have tried syscall but that doesn't work, syscall mounts the file but as read-write i have tried to give ro argument in the data but still it's mounting as read-write. Here is my go code:

Answered 2022-Jan-25 at 14:23Read-only mode is defined by the syscall flag MS_RDONLY, which is also defined in the syscall package. So the call should be:

I used the vpc module to create my VPC via the following code:
ANSWER
Answered 2022-Jan-21 at 09:05You can't change that, as this is how the aws vpc module works. You need custom designed VPC for that. So you have to either fork the entire module and made the changes that you want, or create new VPC module from scratch tailored to your needs.
QUESTION
I have just set up a kubernetes cluster on bare metal using kubeadm, Flannel and MetalLB. Next step for me is to install ArgoCD.
I installed the ArgoCD yaml from the "Getting Started" page and logged in.
When adding my Git repositories ArgoCD gives me very weird error messages: The error message seems to suggest that ArgoCD for some reason is resolving github.com to my public IP address (I am not exposing SSH, therefore connection refused).
I can not find any reason why it would do this. When using https:// instead of SSH I get the same result, but on port 443.
I have put a dummy pod in the same namespace as ArgoCD and made some DNS queries. These queries resolved correctly.
What makes ArgoCD think that github.com resolves to my public IP address?
EDIT:
I have also checked for network policies in the argocd namespace and found no policy that was restricting egress.
I have had this working on clusters in the same network previously and have not changed my router firewall since then.
...ANSWER
Answered 2022-Jan-08 at 21:04That looks like argoproj/argo-cd issue 1510, where the initial diagnostic was that the cluster is blocking outbound connections to GitHub. And it suggested to check the egress configuration.
Yet, the issue was resolved with an ingress rule configuration:
need to define in
values.yaml.
argo-cddefault provide subdomain but in our case it was/argocd
QUESTION
I need to query some WMI values using PowerShell from Windows 10 devices. The script is executed in the context of a non-admin user by some software distribution tooling.
There is a local admin account, and for the current purpose (retrieving information before wiping the system) it wouldn't be a problem to put the password in the script. As automation is a hard requirement, there is no way to deal with UAC windows or the user to enter some credentials.
Is there any way to get
...ANSWER
Answered 2021-Dec-31 at 13:43Can I somehow self-elevate it by just having the admin credentials?
No you cannot. UAC is designed to prevent exactly what you are trying to do. Related Q&A:
- elevate without prompt - verb runas start-process
- UAC Getting in the Way of EXE Install Powershell
- Powershell provide credentials for RunAs
There may be many workarounds, but they all will have in common that you have to go to your machines (locally or remotely) at least once, gain administrative privileges and prepare something, e. g.:
- A scheduled task that runs under your local administrator account or under SYSTEM and triggers the execution of your script
- Disabling UAC (temporarily) (not recommended either way)
- Installing any remote management software, services or accounts (with extra run as background job privilege)
QUESTION
I'm trying to use IntelliJ IDEA to run a Tomcat server but failing to so, I keep getting the following error code:
Application Server was not connected before run configuration stop, reason: java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is: java.net.SocketException: Connection reset]
As seen in the following picture: https://i.stack.imgur.com/yqYav.png
Also, I manage to run a Tomcat server in CMD, but it just doesn't seem to work in IntelliJ. This is a pic of me running Tomcat in CMD succesfully and trying to connect to the same port in the IntelliJ (obviously failing to do so) but it does seem to be trying to connect, as in there is nothing really blocking the connection: https://i.stack.imgur.com/OYIvK.png
I tried every solution I could find:
- specify the same port for both JMX and RMI conversation (here and here)
- configure the Tomcat server again (here)
- make the the path to the Tomcat files is correct (here)
- made sure no Firewall/antivirus is blocking the network connection.
- uninstall and install again both IntelliJ and Tomcat
- specify the IP (here)
- using different ports
Thanks!
...ANSWER
Answered 2021-Nov-09 at 07:09The problem was solved.
Running the Apache Tomcat Installer instead of just downloading the zip solved it.

PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
