Connect emacs simulator to clojure vagrant host

I am trying to use vagrant

, Clojure

and emacs

together. In particular, I cannot connect cider

to my machine vagrant

.

It works locally when I run cider-jack-in

inside my project. But I don't know what steps need to be taken in one project (synced via roaming shared folders) on a roaming machine.

Here's my attempt:

• ssh vagrant
  
  then cd my-project-dir
  
  thenlein repl
  
  
• in emacs,, cider-connect
  
  input vagrant@192.168.50.50
  
  , port22
  
  

I receive the following message:

SSH port forwarding error. check the nrepl tunnel buffer.

Inside this buffer:

OpenSSH_6.2p2, OSSLShim 0.9.8r Dec 8, 2011 Privileged ports can only be forwarded by root.

Nrepl tunnel process exited abnormally with code 255

Ho, am I running this as root? Is this really a problem? Should I be using a different port? Do I have to put something specific in my Clojure code to enable this? The directions given here are a little unclear to me.

Note : it is different from this question because it emacs

works on the host machine, not the machinevagrant

Edit :

Here are the detailed steps I took, thanks to @ Shlomi's answer:

• Modify .ssh / config adding the following (edit the IP to your address Vagrantfile
  
  ):

  Rogue host HostName 192.168.50.50 Port 22 Custom rogue ForwardAgent yes

• in the host, run my project with lein repl
  
  . Pay attention to the port in the message:nREPL server started on port 42018 on host 127.0.0.1 - nrepl://127.0.0.1:42018
  
  

• in emacs,, the M-x cider-connect
  
  login firewall, your password and port noted by the previous command lein
  
  .

• What is it:)
