SSHFS is a network filesystem that relies on SSH service to transfer files. Once a volume is connected, the files in the remote system are available on the user's computer as if they were local files. There is a wide variety of software available for Windows, MacOS or Linux able to connect a network volume via SSHFS. Most Graphical User Interfaces to connect SSHFS volumes, mainly on Windows or MacOS, fail to comply with LUNARC's mandatory Second Factor authentication. This guides describes a method to connect a remote SSHFS volume using a linux terminal, even with LUNARC's second factor authentication.

Connecting a SSHFS volume

Make sure the SSHFS client is installed on your system (Debian: apt-get install sshfs, Fedora: dnf install fuse-sshfs). Create a directory in your home directory on your local (non-LUNARC) computer, where your files hosted at LUNARC will be accessible, for example ~/media/aurora-home.

username@localhost:~$ mkdir -p ~/media/aurora-home

Use SSHFS to connect the directory at LUNARC, that you want accessible on your local computer. Here we assume lunarc user lunarc_username to connect its home directory on Aurora:

username@localhost:~$ sshfs ~/media/aurora-home
( Password: 
( Enter your Pocket Pass OTP: 248921

Your LUNARC files are now accessible on your local computer:

username@localhost:~$ ls ~/media/aurora-home/
 create                      slurm-6411487.out   slurm-6890513.out
 Desktop                     slurm-6411488.out   slurm-6890522.out
 dev                         slurm-6411489.out   slurm-6890523.out
 Documents                   slurm-6411504.out   slurm-6890525.out

Disconnecting a SSHFS volume

This example assumes the LUNARC directory connected in the example described in section "Connecting a SSHFS volume". Use fusermount's option -u to disconnect the remote volume:

lunarc_username@localhost:~$ fusermount -u ~/media/aurora-home
