When making an SSH connection using username/password authentication in TinyTERM for iPad 1.2.1, the app hangs and the keyboard disappears after entering the password. This does not affect public key authentication.

This is tied to challenge-response authentication on the host. If that is enabled, then the connection hangs.

The best fix is to update TinyTERM for iPad. Version 1.2.2 resolves this issue. If you do not wish to update, disabling challenge-response authentication will also prevent the error. To do that, search for this line in the host’s /etc/ssh/sshd_config file:

ChallengeResponseAuthentication yes

It may be commented out with the # symbol. If so, remove that symbol and change yes to no:

ChallengeResponseAuthentication no

Restart the SSHD daemon on the host after making this change. The connection will work properly at that point.
