User not detected when calling shell in remote dired

User not detected when calling shell in remote dired

[reza]

Hi all

When I open a remote folder with dired C-x d /ssh:myuser@myremote and 
call M-x shell there, emacs displays in the minibuffer

Remote shell path: /ssh:nil@myremote:/bin/sh

and I have to manually override my user. How can I instruct emacs to 
pick the correct user or even pick up the user from my ~/.ssh/config file?

And is there also a possibility to change the default remote shell?

Thanks for any help!

Best,
Reza

I guess you mean "/ssh:myuser@myremote:", with the trailing colon.

I cannot reproduce it. I've opened "/ssh:albinus@ubuntu-2204:". When I
call 'M-x shell', Emacs offers me in the minibuffer

--8<---------------cut here---------------start------------->8---
/ssh:albinus@ubuntu-2204:~//bin/sh
--8<---------------cut here---------------end--------------->8---

which is fine. What Emacs and Tramp versions are you using? I've
performed my tests with Emacs 30.0.50 and Tramp 2.1.7-pre.

Could you try to reproduce the problem after starting "emacs -Q"?

When the user is given in ~/.ssh/config, you don't need to specify
it. Just open "/ssh:myremote:".

Set explicit-shell-file-name to a proper value.

Hi Michael

Thanks for the pointers. I also could not reproduce the issue with emacs 
-Q. After disabling most of my config I found the culprit to be some 
helm configuration. It also made the whole tramp experience kind of 
sluggish. Therefore I disabled helm completely and am now blown away by 
the speed!

Thanks a lot!

Best,
Reza
