There are apps for linking filesystems so that you can access data across machines. It's like mounting a shared drive. Here we present a GUI and a command line way of accomplishing this.
MacFusion
MacFusion is no longer working as of macOS 10.12 (Sierra). Please use the command line instructions below.
sshfs
Installation
macOS
Download and install the two packages on this website: https://osxfuse.github.io/
- FUSE for macOS
- SSHFS
Linux
Red Hat
yum install sshfs
Debian
apt install sshfs
Usage
Let's say you want to mount Hoffman2 locally. In your Mac terminal, using the command line, execute:
$ id uid=1010(joebruinuser) gid=20(bruingroup1),23(bruingroup2),... $ mkdir ~/MOUNTPOINT $ sshfs -o idmap=user -o uid=1010 -o gid=20 USERNAME@hoffman2.idre.ucla.edu:/path/to/mount ~/MOUNTPOINT
Where,
id- Gets information about your local user, including your numerical ID and group ID(s)
-o idmap=user -o uid=1010 -o gid=20- Translates your local user and group IDs to that of the remote user so you can read and write files as if you were on the remote machine. Make sure to put the correct user and group IDs that were returned by the
idcommand. USERNAME- Is your username at the remote computer.
hoffman2.idre.ucla.edu- Is the address of the remote computer you are connecting to.
/path/to/mount- Could be left blank to mount your home directory from the remote computer, or it could specify any point in the remote filesystem.
MOUNTPOINT- Is the name of the directory where the remote filesystem will be mounted.
To unmount:
- Use the command
umount ~/MOUNTPOINT
or
- Right click on the desktop icon that appears and select "Eject."
Permission Error
SSHFS has two permission checks, one performed by the macOS and one performed by the remote filesystem. In certain cases, the remote host will allow access to the directory but the macOS encounters issues translating the filesystem permissions. This will result in a permission denied error.
If you run into this permission denied error:
- Double check that you are using the correct user and group IDs that were returned by the
idcommand. - Include the option
defer_permissions.
Where,
-o defer_permissions- Disables local permission checks and defers all permission requests to the remote server.
