Prerequisites

Table of Contents

In order to use SSH on your macOS Ventura device, you will need to have the following:

-A computer with an SSH client (such as PuTTY)
-An internet connection
-The IP address or hostname of the remote computer you want to connect to
-The username and password of an account on the remote computer

Once you have all of these things, you should be able to connect to the remote computer using SSH.

What is SSH?

SSH is a secure protocol for accessing remote servers. It uses encryption to secure communications between a client and server. SSH is typically used to access shell accounts on remote servers.

When you connect to a remote server using SSH, you are authenticating yourself to the server with your SSH key. This key is generated by a key pair that consists of a public and private key. The private key is stored on your local machine, while the public key is added to the authorized_keys file on the server.

When you connect to a server using SSH, the server checks if your public key is in the authorized_keys file. If it is, then the server will send you a copy of its public key. Once both sides have exchanged keys, they can then start encrypting communications with each other using symmetric-key cryptography.

One Primary Reason Why SSH is not working With macOS Ventura is that the new Os comes with OpenSSH 9.1/9.1p1 and because of this the RSA signatures are disabled by Default.

How to fix the SSH not working issue in macOS Ventura?

If you are facing the SSH not working issue in macOS Ventura, then you can follow the below steps to fix it:

1) Firstly, check whether the SSH server is running or not. You can do this by opening the Terminal and executing the command “ps -aux | grep sshd”.

2) If the SSH server is not running, then start it by executing the command “/usr/sbin/sshd”.

3) Now, check the status of the SSH service by executing the command “systemctl status sshd”.

4) If you see that the SSH service is active and running, then try to connect to your server using the SSH client.

5) If you are still unable to connect to your server, then check the firewall settings and make sure that port 22 is open for incoming connections.

Fix SSH not working in macOS Ventura

If you’re having trouble connecting to a remote server via SSH in macOS Ventura, there are a few things you can try to get it working again.

First, make sure that the remote server is accessible and that your credentials are correct. If you’re able to connect to the server via another method (like FTP), then the problem is most likely with your SSH configuration.

To check your SSH configuration, open the Terminal application and type “ssh -v”. This will show you the verbose output of the SSH connection attempt. If you see any error messages, try Googling them to see if there’s a fix.

If your SSH configuration appears to be fine, the next step is to check the firewall settings on both your computer and the remote server. Make sure that port 22 (the default port for SSH connections) is open on both sides.

Finally, if all else fails, you can try connecting to the remote server using a different SSH client. There are many different options available (including free and paid ones), so experiment until you find one that works for you.

PROS and CONS OF SSH
