How to use ‘ssh -i <identity_file>’ with Tramp?

How to use ‘ssh -i <identity_file>’ with Tramp?

[Pankaj Jangid]

When I edit remote files using ssh with default options, it works fine. But now
there is a requirement to use an identity_file with option -i. How to add this
option when connecting using Tramp?

On command line I connect using this command,

ssh -i <identity_file> user@host

I would create ~/.ssh/config and populate it with your command-line
options:

#+begin_example
Host ssh-example-com
     HostName           ssh.example.com
     User               someone
     Port               4321
     IdentityFile       ~/.ssh/ssh.example.com
#+end_example

Then,

ssh ssh-example-com

will do what you want. Or

C-x C-f /ssh:ssh-example-com:. RET

will open the home directory of "someone" on ssh.example.com.

HTH,
Leo

Thanks. This works. And I found another option also. Use ssh-add to add the
IdentityFile to ssh’s own store. And then use ssh as usual.

Meta: I hade to fill these quotes manually. Only your mails.
      What's up with the lines?

But to answer your question, see the use of -i here:

  https://dataswamp.org/~incal/emacs-init/tramp-incal.el

Actually it isn't that, that's sh(1) or dash on Debian which
isn't even secure.

I have set fill-column to 47 in message
mode. Like this paragraph.

But to send posts in this mailing list, I just do ‘C-u 79 C-x f’ like
in this paragraph. Is this causing an issue.

No, not this time, I think?

But actually it's not an issue re-filling them either. A lot
of people do that.
