cannot ssh edit a file

cannot ssh edit a file

[Luca Ferrari]

Hi all,
I'm using emacs 26.3 on ubuntu linux, and I cannot tramp via ssh into
a machine to edit files.
What happens is that once I digit /ssh:luca@remotehost: Emacs freezes.
I've ssh keys in place, and I cannot connect with a terminal and ssh
regularly. I've tried changing the shell of the user, since the remote
user was using zsh and I've read that some particular prompts can
confuse tramp, but nothing changed.
I've tried the same using M-x find-file, but it freezes again.
I've noted that trying to connect with a user that does not have ssh
keys prompts me immediatly for the password, but once the password is
entered, emacs freezes.

Any idea about how to investigate and fix the problem?

Thanks,
Luca

I use ~/.ssh/config to configure my hosts. Something like:

Host remotehost
     User		mename
     HostName		aa.bb.cc.dd
     Port		5555
     IdentityFile	~/.ssh/remotehost

Then

C-x C-f /ssh:remotehost: RET

opens the home directory of `mename'.

To troubleshoot, I would suggest configuring the host as above and then
executing

ssh -v -v remotehost

in the terminal. That will likely give you an idea of what is wrong.

Alternatively, I would suggest using sshfs.

No way, as I press the colon after the config hostname Emacs freezes.
Since the ssh is working fine from the terminal, even putting extra
-vvv does not provide to me any clue.
Any way to trace down what Emacs is doing?

I've also tried with the 27.1 version of Emacs, built from sources,
but nothing has changed: the behavior is the same, therefore there
must be something tied to the SSH level that I cannot understyand.

Can you reproduce the problem from `emacs -Q`?

Apparently this works a little better: it does not freeze on the colon
typing, but when I try to open a file the minibuffer keeps saying
"Waiting for prompts from remote shell..." and the connection is not
established. This happens both with remote users that have zsh or sh
as login shells.
The only difference is that with sh as default shell, the minibuffer
says "Tramp: Found remote shell prompt on miguel" (miguel being the
remote host) and nothing happens, no connection is made.
I've inspected connections from the remote host point of view, and
there is no ssh connection reported by netstat.

So from `emacs -Q` did you apply Óscar's advice regarding setting the TRAMP
verbosity level? This feels likely to be an ssh configuration problem on
either the local end (in ~/.ssh/config etc.) or on the remote end in your
shell init files. TRAMP can be particularly difficult to debug in this kind
of situation, though.

My post about how to only customize your prompt when the shell is
interactive may be interesting to you as well.

Please set tramp-verbose to 10, and rerun the test. There will be a
Tramp debug buffer, which shall tell us what's happening.

I must be doing something wrong, since I've done (setq tramp-verbose
10) and evaluated the buffer, but nothing appeared anywhere (both with
or without -Q startup).

I've changed the shell from zsh to bash, I've changed the prompt
according to suggestions to get a standard prompt, but the symptoms
are the same.
I've checked that logging into different machines works, so I've
problem only with a FreeBSD host and a Fedora host that are currently
not working fine.
I've tried to ssh with or without keys but when Emacs has to open a
file it freezes. I've also tried, as a desperate approach, to connect
via IP instead of hostname, but nothing changed.
What puzzles me is that I cannot see the connection established on the
remote side.

For further analysis, we need the traces. Pls start

# emacs -Q --eval '(setq tramp-verbose 10)'

and run your test. After wards, there will be a buffer
*debug tramp/ssh host* which contains the traces.

I suspect it is a problem with your *local* prompt then.

No. The traces do not seem to be produced with tramp-verbose 10. And
they are not complete.

Please start Emacs as I havce shown above. Run the test, and send the
*complete* debug buffer, preferred as attachment.

I don't know exatly what you mean by complete, however I started emacs
as follows:

% /opt/emacs/emacs26.3/bin/emacs -Q --eval '(setq tramp-verbose 10)'

and ssh-ed into the machine. I waiting for many minutes, because Emacs
is frozen, then C-g and switched to the buffer. I attach the log.

Based on the log here it looks like you are connecting to `luca@miguel` and
receiving back some odd text, namely:

```
16:56:45.839707 tramp-accept-process-output (10) # *tramp/ssh luca@miguel*
run nil
Last login: Mon Feb 22 15:58:27 2021 from n261732
%



[45mluca@miguel [49m [35m~ [37m % [39m [49m [?2004h
```

which I think indicates that whatever you did to correct your prompt on the
remote machine isn't working.

This is the exact command that TRAMP is using to attempt the connection:

```
ssh -l luca  -o ControlMaster=auto -o ControlPath='tramp.%C' -o
ControlPersist=no -e none miguel
```

Are you able to connect from a shell using that command?

Indeed. Looks like zle prompt from zsh. Please read the Tramp manual
about.

Apparently I'm too dumb to set the dumb terminal:
% ssh luca@miguel 'tail -n 1 .zshrc'
[[ $TERM == "dumb" ]] && unsetopt zle && PS1='$ ' && return

While I confirm I have zsh on the remote host, with the adam prompt
that uses colors, I've also tried to change the shell to bash without
any fancy prompt and nothing has changed.
As well as wth the dumb terminal Emacs still freezes.
And again, I've tried another user on the remote side that has a sh,
so no fancy prompts at all!

I'm able to connect with the tramp ssh command:

% ssh -l luca  -o ControlMaster=auto -o ControlPath='tramp.%C' -o
ControlPersist=no -e none miguel
Last login: Tue Feb 23 08:58:09 2021 from n261732
luca@miguel ~ %


I've also tried to unset PS2 and PS3 when using dumb terminal, without
any succcess:
% ssh luca@miguel 'tail -n 1 .zshrc'
[[ $TERM == "dumb" ]] && unsetopt zle && PS1='$ ' && unset PS2 &&
unset PS3 && return

Then I tried to ssh to localhost, I mean I logged into the remote
host, started emacs locally, and C-x C-x /ssh:luca@localhost: and it
worked, therefore it does not seem a problem with the zsh prompt,
rather a problem with tramp on my local machine.

Any other suggestion?

Thanks,
Luca

So right here I think you're still showing evidence that whatever you're
doing to attempt to change the PS1 isn't taking.  The prompt (if your
customizations were working) should be `$ ` exactly, not `luca@miguel ~ %`.

Until you can use that ssh command and get a prompt that's exactly `$ ` I
don't think there's much else (I at least) can do to help you. I don't know
zsh at all so I can't help you figure out why your prompt customization
isn't helping. Perhaps zsh has a mailing list or other forum you can use?

I've also tried to unset PS2 and PS3 when using dumb terminal, without

This is interesting but there's too much that could be different between
the emacs versions and configurations and the ssh setup for this to be
particularly useful. I guess you could do the tramp verbosity level thing
on the remote machine and verify that you're not getting the bad prompt as
you've shown you still are when connecting from your local machine using
the tramp command.

Yes, because I mistakenly added the "dumb" line to the end of the
file, instead of the head. Now I've fixed:

% ssh -l luca  -o ControlMaster=auto -o ControlPath='tramp.%C' -o
ControlPersist=no -e none miguel
Last login: Tue Feb 23 17:19:39 2021 from n261732
$


however, nothing has changed, and launching emacs with tramp verbose:

% /opt/emacs/emacs26.3/bin/emacs -Q --eval '(setq tramp-verbose 10)'

and opening an ssh file I got emacs frozen as before, but the tramp
buffer does not shows anything at all even after minutes.

I'm quite depressed!

Unfortunately if the tramp traces aren't available I think there's nothing
else I can do to help you. I would just be sure to double check everything
to make sure you're typing everything accurately etc. I haven't seen the
TRAMP debug facilities fail like that and that's pretty battle-tested
software so I think it's likely that you're simply mistyping something.

Good luck!

Don't give up. We've managed such problems in the majority of cases.

I guess you can still apply "C-g", several times, to unblock Emacs. Send
the debug buffer then to us. The whole debug buffer, as usual.

I have a little improvement on this: after installing tramp 2.5.0 the
situation has improved. Now I'm able to remotely dired into my home
folder. However, if I try to open a file, Emacs still freezes. I see
in the minibuffer a message that states "trying to exit with no
candidates".
Nothing changes using a dummy terminal in my .zshrc:
[[ $TERM == "dumb" ]] && unsetopt zle && PS1='$ ' && return
or changing the shell to bash (neither sh).

Here it is the tramp debug buffer content.
Thanks,
Luca

Achhhh ...

As I said several times, pls start "emacs -Q", adapt the load path to
the GNU ELPA Tramp version, set tramp-verbose to 10, and after that try
what you want to do.

And please send the *whole* debug buffer, as attachment. Otherwise, we
won't be able to analyze what happens.

Sorry about that, I started emacs with:

% /opt/emacs/emacs26.3/bin/emacs -Q --eval '(setq tramp-verbose 10)'

then tryied to open a file with
C-x C-f /ssh:luca@miguel:git/pgenv/bin/pgenv

and I saw tramp was still the embedded version. I then reinstalled the
2.5 version and the remote file opened.
Now I need to understand why without the -Q start option, and thus my
current emacs configuration, the same tramp version is not working.

Suggestions? I'm not attaching the log of the working session, do you
need it to understand what could cause the problem when starting emacs
without -Q?

Thanks,
Luca

I recommend you bisect your .emacs file, until you find the guilty
configuration setting.

Tramp 2.5 has some better support for settins zsh options. You could try:

- Install Tramp 2.5.0.1 from GNU ELPA. It shall be compatible with Emacs 26.

- Assure, that your Emacs uses this Tramp package, and not the builtin
  one. Once you have loaded Tramp, check variable tramp-version.

- Apply the following setting in your .emacs, prior accessing the remote
  host:

     (add-to-list 'tramp-connection-properties
                  (list (regexp-quote "/sshx:user@host:")
                        "remote-shell" "/usr/bin/zsh"))

  "user" and "host" must be adapted.

- Use "sshx" to open a remote file, like "C-x C-f /sshx:user@host:".

Best regards, Michael.
