amacsclient with emacs daemon/server on remote host

[lee]

Hi,

I'm trying to find out how I could run an instance of emacs on a remote
host and access this instance with emacsclient over the network.

Currently, I'm doing this all the time with the instance of emacs
running on the local host with (server-start) in my ~/.emacs.  I'd like
to do the same, but with emacs running on the remote host.

Is this even possible, and if so, how do I tell the server to listen on
a port for network connections?

Did you found a way to do that? I'm trying to find a way to connect from OS X to an emacs daemon in my vagrant box.

A crazy long time ago I did this, when networks and computers were 
slower and security wasn't so formidable, but it should still be doable 
today... and probably faster.  Essentially your local machine becomes 
and X server, meaning your local machine's display, keyboard, mouse, 
etc. are used when running a command (here, emacs) on the remote 
machine.  Wild guess would be to run locally 'ssh -X -c "emacs 
filename"'.  But you'd likely need to configure X, Xclient, and the 
security bits so you don't get Denials.

I dont know Macs, so that's another game altogether.  I was working with 
Linux on both ends.  Sorry.

Please let us know what you get to work.

About twenty years ago, there was a gnuclient/gnuserver combination that
allowed connections over TCP sockets, written IIRC by Andy Norman, who
also wrote ange-ftp, the precursor of tramp. But slowly, its
capabilities were migrated to the built-in emacsclient/server, which I
believe can now use TCP sockets - for more details, see

C-h v server-use-tcp RET

and

M-x man RET emacsclient RET

for the --server option.

Perhaps

http://stackoverflow.com/questions/12546722/using-emacs-server-and-emacsclient-on-other-machines-as-other-users

will be helpful also: I did not read all of it and I certainly have not
tried anything out.

There are options for the server to use tcp: `server-use-tcp' (since
22.1) and to fix the port used: `server-port' (this one since 24.1.

That said, do consider Tramp mode, which is really, extremely nice.
Just when you visit a file, enter its path as:

  /ssh:my.other.system:/path/to/file

It asks you for a password (or passphrase) and... voilà. Caching,
bookmarks, all sorts of useful things Just Work.
