I was unable to login from my old iMac running Yosemite to my new iMac running Ventura using RSA keys. It turns out that RSA key support was disabled in Ventura. To correct the problem, I added the following two lines to the bottom of BOTH /etc/ssh/ssh_config and /etc/ssh/sshd_config on the Ventura side:
I have been using RSA SSH keys forever to login to my various AWS EC2 instances. With macOS Ventura 13.3.1 ssh failed with the “Permission Denied” error. Using ssh -vvv, I saw that the RSA key was now being rejected. After much research, I decided to implement new keys on the client (Ventura) side using […]

This is the error from the /var/log/auth.log file: Dec 9 16:47:55 localhost sshd[1550]: userauth_pubkey: key […]

I had some odd issues with slow login via ssh to my host. I looked in Console.app, but was not able to find anything relevant. So here is what I did: 1. System Preferences -> Sharing, Unchecked “Remote Login” 2. In Terminal, as root, ran /usr/sbin/sshd -ddd -e (3 d’s for debug level 3, -e […]
