I am running graphical Emacs 24.3.1 (this problem exists when using the console version as well) on Arch Linux. I am trying to use TRAMP to open files on a remote Fedora system by SSH with a private key which requires a password. Authentication works fine, and so does the listing of files. When I do try to open a file, my Emacs session hangs with "Tramp: Inserting `/{filename I'm trying to open}' ...done". It is not possible to abort with ESC ESC ESC or C-g. Does anyone have a solution to this?

Emacs 24 normally works very well with Tramp. What you might need is ControlMasterAuto
in your .ssh/config file. This will ensure that the ssh connection information passes seamlessly to Emacs. This will also ensure that you only need to login once in a terminal and use multiple emacs frames in tramp mode. I have detailed the following steps
(1) Go to your .ssh/config file and add the following options
Host <hostname>
ControlMaster auto
ControlPath ~/.ssh/%r@%h:%p
ServerAliveCountMax=30
ServerAliveInterval=5
(2) Now login to the remote host through terminal.
(3) Open emacs frame and try opening the remote files through tramp (/ssh:). You must be able to connect to the remote host.
The above steps should work even for a two level authentication (using a rsa key +password).
tramp-verbose
variable should probably be your first port of call. – philstramp-verbose
to5
could indeed solve the hangs. I tried it, and now I can indeed open files on the remote host. I then tried removing the(setq tramp-verbose 5)
from my.emacs
again so that I could tell you the message in the minibuffer when it hangs, but miraculously, I can still open files. – justinpcTramp: Inserting `filename'...done
