I am having some problems with Tramp logging in to remote servers. In
my ~/.ssh/config I have:
Host blacky.wilkesley.net
IdentityFile ~/.ssh/id_rsa_blacky_linode
Host wilkesley.org
IdentityFile ~/.ssh/id_rsa_linode_ian
I can login to either host using ssh wilkesley.org or ssh
blacky.wilkesley.org. However, tramp logs in OK to wilkesley.org, but
*not* to blacky.wilkesley.net.
If I use the following minimal init file:
(setq tramp-shell-prompt-pattern "^[^$>\n]*[#$%>]*\\(\[[0-9;]*[a-zA-Z]
*\\)*")
(eval-after-load 'tramp '(setenv "SHELL" "/bin/bash"))
(setq tramp-default-method "ssh")
(setq tramp-verbose 10)
I get the following in the Tramp log when I try to login to
blacky.wilkesley.net:

For some reason it looks as thought the host key verification is
failing, but I can't see why.

A bit more information. Here is the log from the serer when tramp fails
to login:

It appears that the public key is accepted OK, but Tramp just hangs. The
sshd config file is identical on the server that works and the one that
doesn't.

Likely, there is a problem with your prompt. Use tramp-verbose 10, and
show the debug buffer.

You were right. The actual prompt looks the same on both computers.
However, I tried copying .zshrc from the computer that worked to the one
that didn't and now I can connect via Tramp OK.
I thought that .zshrc was the same on both computers, but obviously it
wasn't. Time to run diff and find out what the problem is.
Ian.

Good luck. With zsh, it is often the zle which runs into problems with
Tramp. I've written some hints in the Tramp manual how to manage it.

Nice. Can you give the link of your hints?
Also, I got the problem when I tried to use tramp:
sudo: no tty present and no askpass program specified
I have installed openssh-askpass.

It's in the FAQ section of the Tramp manual. Eval

Well, how to you use sudo? From your local machine, or do you hop onto
another machine (via Tramp), and apply sudo there?
> I have installed openssh-askpass.
Usually, you could instruct sudo to use your askpass program by setting
the environment variable $SUDO_ASKPASS. See the man page of sudo(8).
Best regards, Michael.

Thank you, Michael.
I use sudo on my local machine with C-x C-f /sudo::
Now I start Emacs by SUDO_ASKPASS=openssh-askpass Emacs -q.
There is no message in *tramp/sudo...* buffer, but it still does not
prompt for my password.

Apply (setq tramp-verbose 10) prior to the connection. There will be a
buffer *debug tramp/sudo...* which shall tell us what happens.

Thank you for your hint.
I now start Emacs with: SUDO_ASKPASS=/usr/bin/qt4-ssh-askpass emacs -q.
And then I apply (setq tramp-verbose 10).
With C-x C-f /sudo::<enter>, it prompts for user/password.
After I input my account and password, it just hangs there...
So I hit C-g, and I find hundreds lines of messages in the debug buffer.
It seems to be some loop there. Here is just the last one loop of messages:
