I would like to use tramp to login to a remote server via SSH.
It used to work effortlessly, but somehow it does not even ask me for a password any longer and tries wildly to login with I guess keys from ~/.ssh or something, until the server gives me:
Received disconnect from MYSERVER port 22:2: Too many authentication failures
How do I force tramp to not try anything, but always use password authentication? I also do not wish to use an authentication file currently. I have found many questions where an authentication file was the chosen solution, but I would like to stick with Emacs asking me for a password for now. I am looking for the tramp equivalent of:
ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no MYUSER@MYSERVER
I already have the following in my init.el:
;; ==========
;; TRAMP MODE
;; ==========
(setq tramp-default-method "ssh")
(setq tramp-verbose 5)
(setq password-cache-expiry 86400)
(setq auth-source-debug t)
(setq auth-sources '())
I also have a hunch, that it might be, that tramp does not notice, that the server asks for a password, because of a custom MOTD, but am not sure, that this is the issue. The MOTD looks like this:
#####################################

It seems to me that the "sending command" part: Sending command ‘exec ssh -l MYSERVERUSER -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none MYSERVERIP’ is wrong, or at least not what I want.
