Ssh to Debian host hangs

General
1

(I ran into this years ago …I know I need to change a setting somewhere)

When I try to ssh from my Aurora-DX laptop to a new Debian bookworm host ( Aurora raspberry pi on local network) my session hangs at the same place.
Mac OS X using iTerm works perfectly.
I seem to remember having to change a setting in my ssh client, but I can’t find it.

my ~/.ssh/config has:

Host *
	KbdInteractiveAuthentication yes
	IdentityFile ~/.ssh/id_ed25519

but when I ssh -v I get:

OpenSSH_9.9p1, OpenSSL 3.2.4 11 Feb 2025

… and rebooting the machine worked.
So the key is:

	KbdInteractiveAuthentication yes
