SSHFS
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/cosmos-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 COSMOS:
username@localhost:~$ sshfs lunarc_username@cosmos.lunarc.lu.se:/home/lunarc_username ~/media/cosmos-home
(lunarc_username@cosmos.lunarc.lu.se) Password:
(lunarc_username@cosmos.lunarc.lu.se) Enter your Pocket Pass OTP: 248921
username@localhost:~$
Your LUNARC files are now accessible on your local computer:
username@localhost:~$ ls ~/media/cosmos-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:
