ssh-keygen | Generates SSH key-pairs in node.js | Runtime Evironment library

I have 2 instances, 1 VPC and 2 subnets each one in different region.

1 instance has a public IP, the other one just have internal IP. I want the 2 instances to communicate with each other using their internal IP.

How can I achieve this?

Now, what I am trying to achieve: connect from local to instance-b via ssh usinf external IP. I just want instance-b to connect to instance-a via ssh using internal IP ie: ssh user@instance-b-external-ip >> ssh user@instance-a-internal-ip

I can ping, but when I try to connect to instance-a from instance-b using internal-ip via ssh, it always say permission denied.

New Edit SSH

I connect to instance-b using external-ip ie: ssh user@externalip. Inside instance-b i create ssh keys using the following command

I created a public key in Git using ssh-keygen which was successfully created as .ssh/id_rsa.pub.

I then uploaded it to GitHub in my SSH Keys, and "Authorized" its SSO feature. Everything is uploaded now.

When cloning a repository in Eclipse, I get the following message

Today when I execute the yarn command in the macOS(Intel Chip), show error like this:

• Private GitHub repository: a NodeJS private module/package.
• SSH private-public keys created with ssh-keygen:
  • Private key stored at C:\Users\USER\.ssh\id_rsa.
  • Public key added to GitHub.

To install the private module (hosted on GitHub) using:

• npm install
• SSH public-private authentication (in particular, using the id_rsa SSH private key saved in C:\Users\USER\.ssh).

When I execute:

I'm following the FIDO U2F instructions on https://developers.yubico.com/SSH/ on macOS Monterey with openSSH 8.6 and run into the following issue:

I would like to ask if it is possible to use DVC with several accounts on the same machine. At the moment, all commands (dvc pull, dvc push, ...) are executed under my name. But after several people joined this project too, I do not want them to execute commands under my name.

When I was alone on this project I generated ssh key:

I'm trying to generate ECDSA Key Pair for SSH with Go, but I find that the private key format is different from ssh-keygen and can't be accepted by GitHub.

Here's the 256-bit key pair generated via ssh-keygen -t ecdsa -b 256:

In gitlab's documentation on how to generate ssh key: they suggest to use the -o argument. However, this argument does not seem to appear in the manual of ssh-keygen. No error is thrown so it is acceptable. I am wondering what does it do?

On my remote server all I did is:
