tramp never stops asking for password

Question

I've having serious trouble using tramp on Emacs. I am continuously being asked for my password when I ssh into a server via tramp. This is to the point where it blocks me being able to do anything.

I have looked far and wide on the internet and the most widely used solutions do not seem to work for me.

• I have Emacs 24.*
• I have (setq password-cache-expiry nil)
• I have (setq projectile-mode-line " Projectile")

Here is my tramp setup in my .emacs.d for the curious http://pastebin.com/NJCaa0RH.

Has anyone else had this problem and can point me in the way of a fix? Or do you see a glaring error in tramp config?

Answer 1

• Make sure you can login via keys instead of password. This would involve copying ~/.ssh/id_rsa.pub or ~/.ssh/id_ed25519.pub from your local machine and pasting the same in ~/.ssh/authorized_keys on the server

• Having a ssh config should help simplify the syntax

• Having a persistent connection would also help with your problem

  (customize-set-variable
  'tramp-ssh-controlmaster-options
  (concat
     "-o ControlPath=/tmp/ssh-ControlPath-%%r@%%h:%%p "
     "-o ControlMaster=auto -o ControlPersist=yes"))
