Installing SSHFS to Local Folder on Mac OS X to Edit Files on AWb Ubuntu Instance

I want to be able to edit files locally using a nice IDE and have the files on my local machine ( ~/Code/myproject

) go straight to my Ubuntu computer in the cloud ( /home/ubuntu/myproject

).

I have installed FUSE and SSHFS for my Mac OS X laptop (local).

I have an instance of Ubuntu 16.04 AWS on EC2:

ubuntu@ip-xxxxxx:~$ uname -a
Linux ip-xxxxxx 4.4.0-1017-aws #26-Ubuntu SMP Fri Apr 28 19:48:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
ubuntu@ip-xxxxxxx:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.2 LTS
Release:    16.04
Codename:   xenial

      

        
        
        
      

    

I am using file .pem

for ssh in this flag box -i

(did not configure authorized_keys).

So here's what I am doing on my local machine:

$ mount  # check for mounted
/dev/disk1 on / (hfs, local, journaled)
devfs on /dev (devfs, local, nobrowse)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)

$ sudo sshfs -o allow_other,defer_permissions,IdentityFile=~/.ssh/aws.pem,loglevel=debug \
    ubuntu@ec2-xxxxxxxx.compute-1.amazonaws.com:/home/ubuntu/myproject \
    /Users/me/Code/myproject

      

        
        
        
      

    

It asks me for the local computer password and then I see the following:

Password:
remote host has disconnected

      

        
        
        
      

    

Obviously something is mounted:

$ mount
/dev/disk1 on / (hfs, local, journaled)
devfs on /dev (devfs, local, nobrowse)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)
ubuntu@ec2-xxxxxxx.compute-1.amazonaws.com:/home/ubuntu/myproject on /Users/me/Code/myproject (osxfuse, synchronous)

      

        
        
        
      

    

and if I try to repeat the same command sshfs

as above (without unmoun

-ting) I get another error:

mount_osxfuse: mount point /Users/me/Code/myproject is itself on a OSXFUSE volume

      

        
        
        
      

    

I can disconnect and try again with sudo diskutil umount force /Users/me/Code/myproject/

, but when I try again I get the same original error.

I thought it was a problem with the remote SFTP server, so I found the entire location sftp-server

in the remote field:

$ sudo find / | grep sftp-server
...
/usr/lib/sftp-server
/usr/lib/openssh/sftp-server

      

        
        
        
      

    

And then I tried with both in my /etc/ssh/sshd_config

file with a line:

#Subsystem sftp /usr/lib/openssh/sftp-server
Subsystem sftp /usr/lib/sftp-server

      

        
        
        
      

    

but none of the configuration after reboot seems to work.

I can use SFTP with the following command:

$ sftp -i ~/.ssh/aws.pem ubuntu@ec2-xxx.compute-1.amazonaws.com
Connected to ec2-xxx.compute-1.amazonaws.com.
sftp>

      

        
        
        
      

    

EDIT: debug3

Running loglevel gives relatively the same results:

$ sudo sshfs -o allow_other,defer_permissions,IdentityFile=~/.ssh/aws.pem,loglevel=debug3 ubuntu@ec2-xxxx.compute-1.amazonaws.com:/home/ubuntu/myproject /Users/me/Code/myproject
sudo: cannot get working directory
The authenticity of host 'ec2-xxx.compute-1.amazonaws.com (xx.xx.xx.xx)' can't be established.
ECDSA key fingerprint is SHA256:xxxxxxxxxxxxxxx.
Are you sure you want to continue connecting (yes/no)? yes
remote host has disconnected

      

        
        
        
      

    

Any ideas on what to fix / where the problem might be?
