the problem seems to be due to choice of cipher:

% ssh [email protected] [email protected]
Fssh_ssh_dispatch_run_fatal: Connection to fd00:0:0:1::b port 22: message authentication code incorrect

% ssh [email protected] [email protected]
Last login: Fri Apr 10 08:17:20 2026 from tansy.le-fay.org

if AES is broken, that would also explain why TLS doesn't work.

unfortunately while trying to rebuild world i ran into an unrelated
panic[0], so i'll need to find a workaround for that before i can
test more.
