Can someone give me the correct syntax for making an SSH connection to an EC2 server using tramp (from emacs)? 

What do type after you C-x, C-f and are faced with the "Find file:" prompt? How do you include .pem file? 

Thanks, 
Morgan

I haven't used EC2 myself. But if you could show how you contact an EC2
server via ssh from a shell prompt, it shall be possible to give you the
Tramp equivalent.

For convenience, you can specify the location of the pem file via the IdentityFile parameter in your ssh config file.  Everything else can be done with tramp's usual functionality.

Chris, 

~/.ssh/config does not exist. Can I create it? What goes in it? 

I do find ~/.ssh/local_hosts 

Thanks, 
Morgan

Michael, 

Here is how I connect via shell prompt: 

sudo ssh -i mlhost.pem ec2-user@ec2-107-20-32-xxx.compute-1.amazonaws.com 

Thanks, 
Morgan

I would do in emacs

  "C-x C-f /ssh:ec2-user@ec2-107-20-32-xxx.compute-1.amazonaws.com:"

Why do you need the preceeding "sudo"? Is it mandatory for calling ssh?
In this case, we would need further configuration.

Tramp does not support the specification of identity files via the "-i"
option. Therefore, you shall add the following lines to your ~/.ssh/config:

Host ec2-107-20-32-xxx.compute-1.amazonaws.comx
	IdentityFile	/path/to/mlhost.pem

Best rgards, Michael.

Michael, 

It worked just as you said. 

Also, you were right - it did not need "sudo". 

Thank you!! 

Morgan

I don't know if you're aware of this but if you need to connect
frequently to the same server you can type less if you put the
following in you ssh config (~/.ssh/config):

Host myserver
     Hostname ec2-107-20-32-xxx.compute-1.amazonaws.com
     User ec2-user

You'll be able to connect like this:
- in the shell: $ ssh myserver
- on Emacs: C-x C-f /ssh:myserver:/path/to/file
