In the macOS Terminal, my mouse scroll wheel would magically start scrolling the command line history instead of the window buffer scroll bar on the right to show window history. This happened when an SSH session was disconnected or timed out. The fix is to run the reset command.
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.

If you are asked “Are you sure you want to continue connecting (yes/no)?” when trying to connect via SSH, then the remote host’s identification key has not yet been stored in your ~/.ssh/known_hosts file. This then requires you to type the full string “yes” in order to proceed because the default value for ssh is […]
I use csshX on a daily basis. The default layout on my screen for three nodes is one column with three rows, one per node. This layout is excellent for visual positioning, but does make it harder to read long output. For this purpose, I start csshX using the column quantity specifier -x and I […]
Recently I had to launch an Ubuntu instance in AWS because i needed to run alien to convert a .rpm into a .deb package. When I added my SSH keys as usual, I found I was still unable to login. This is the error from the /var/log/auth.log file: Dec 9 16:47:55 localhost sshd[1550]: userauth_pubkey: key […]
