Create it if it doesn't exist.  Create the ~/.ssh/ directory first, if
that doesn't exist either.

More generally, ~/.ssh/config (which does not exist by default but which
can be created) is the user-level configuration for the ssh client
program.  The system-level defaults are in /etc/ssh/ssh_config.

Also, as long as you're messing with ~/.ssh/config you might want to
set up a keepalive in case you ever communicate through a NAT router.

ServerAliveInterval 300

will send a packet every 300 seconds, which (hopefully) prevents a NAT
router from timing out your idle sessions.

(Yeah, I know, it says "Server" but it's a client-side config option.
I didn't choose the name.)

I know nothing about this "cme" either.

Yes. Qu'est-que "cme?"

Some esoteric breed of editor?

You will love the first statement in its man page :)~

       cme - Check or edit configuration data with Config::Model

It invites us all to participate in improvement

   FEEDBACKS
       Feedback from users are highly desired.

I guess perl docs can give info additional to the man page.
  http://search.cpan.org/dist/Config-Model/lib/Config/Model.pm
says

  "Config::Model - Create tools to validate, migrate and edit configuration
   files."
  "Config::Model enables a project developer to provide an interactive
   configuration editor (graphical, curses based or plain terminal) to
   users."

Obviously it knows several file formats and even the file names
which it shall operate on.
For me it checks my Debian packaging preparations by

  cme check dpkg

(Zero answer is good answer, then.)


Have a nice day :)

ssh_config is probably the most under-appreciated part of the client.
Yet it's very useful.  Even a lot of 3rd party tools work with it.

The global file is /etc/ssh/ssh_config.  Most users have one located in
~/.ssh/config  For both, the full documentation is in the manual page
for "ssh_config".  If you add a lot of options then it saves a lot of
work to put them in ~/.ssh/config

If the file does not exist, you can make it with your choice of editor.
It follows the basic structure of Host + a pattern or name, followed by
options for that pattern or name.  For example, these blocks add a set
of options below for two remote hosts:

	Host 5501
	  Hostname 203.0.113.22
	  IdentitiesOnly yes
	  IdentityFile ~/.ssh/key_22_ed25519
	  AddKeysToAgent yes
	  ServerAliveCountMax 2
	  ServerAliveInterval 30
	  Port 2223

	Host 33
	  User xyzzy
	  HostName 203.0.113.11
	  ControlPath ~/.ssh/controlmasters/%r@%h:%p
	  ControlMaster autoask
	  ControlPersist yes

The first host with its set of options is available via "ssh 5501", just
as the second one is available via "ssh 33".  The latter would be the
equivalent of

  ssh -o ControlPath=~/.ssh/controlmasters/%r@%h:%p \
	 -o ControlMaster=autoask \
	 -o ControlPersist=yes \
	 xyzzy@203.0.113.11

Or something like that.

I recommend grabbing a refreshment, finding a comfy chair, and working
through the manual page for ssh_config paragraph by paragraph at least
once if you connect to a lot of servers or use a lot of options when
connecting.

Regards,
Lars

You need to install cme package:
$ sudo apt install cme

This will install al required dependencies unless you've configured apt to 
avoid installation of recommended dependencies.

Ah sorry, cme package is available on testing and sid.

On Jessie, cme command is delivered by libconfig-model-perl.
I don't remember how the dependencies were organised, so please  install also
libconfig-model-openssh-perl and libconfig-model-tkui-perl

All the best
