How to mount remote directory in Linux with SSHFS

On the Internet, there is definitely no shortage of file synchronization solutions between the two devices. Google Drive, Microsoft OneDrive, NextCloud, etc . may not give you the official Linux client. But perhaps you do not trust a large corporation in storing your important files. Or, maybe, you want a higher level of security than what NextCloud provides, as there are likely to be unexplored security vulnerabilities in existence.

Why should I use SSHFS?

From an end-user perspective, SSHFS is a simple and very easy to use solution. SSHFS is also extremely secure because it depends on the proven OpenSSH server. SSHFS encryption is also very high, so you can rest assured that no one can steal files during the transfer process. An updated server is correctly configured, only listening to SSH connections, often impossible to crack, unless an attacker comes from NSA or a security specialist, etc. (but maybe they I also don't want to take your files for anything.

Why don't you want to use SSHFS?

If you want the best transfer speed possible, you can use other solutions like NFS. SSHFS is not the slowest option, if your Internet connection is of high quality, it is not the fastest way. And if you want to move folders containing hundreds of small files, this task becomes really terrible. Also, if you want to tweak file sharing settings, based on individual users or other factors, you may want to use another software.

In short, if all you need is an easy, safe, and quick way to synchronize remote folders with a local folder, you'll be happy to use SSHFS.

Install SSHFS

On Arch Linux-based installations, use the following command:

 sudo pacman -S sshfs 

If you use a Fedora-based distribution, use the following command:

 sudo dnf install sshfs 

On Debian and Ubuntu, use the command:

 sudo apt install sshfs 

For OpenSUSE users, enter the following command:

 sudo zypper install sshfs 

Server configuration

If you rent a server or VPS, the OpenSSH server daemon has been configured. Follow the steps suggested by the cloud service provider to configure the regular user (not the root). Some providers allow you to do this directly from the web control panel and even allow you to enter a public key to access SSH. In this case, create local key pairs using the ssh-keygen command. Then enter the public key from /home/your_username/.ssh/id_rsa.pub.

If the cloud provider does not provide a tool to easily enter public SSH keys, do this manually. At the very least, do not allow root login and disable password login. Instead, use only SSH keys because they cannot be brute-force attacks, as is the case with passwords.

If you want to synchronize files between two home computers, just consider one as the server (install the openssh-server package and configure) and consider the other computer as a client, then apply the steps the same, similar.

Mount a local remote directory with SSHFS

First, create a folder that will be synchronized with the remote device.

 mkdir $HOME/sshfs 

Next, mount the local remote directory via SSHFS. Replace the user with the actual user name created on the server and 203.0.113.1 by the actual IP address name of the remote device.

 sshfs user@203.0.113.1:/home/user $HOME/sshfs 

Of course, if you don't want to synchronize the entire user's home directory on the server side, simply replace / home / user with / home / user / some_other_directory after you create it on the server.

When you want to unmount, use this command:

 cd && fusermount -u $HOME/sshfs 

If you want a directory to synchronize permanently with the remote device, add a command like sshfs user@203.0.113.1: / home / user $ HOME / sshfs in the autostart manager. Each graphics manager has a different autostart configuration manager, so refer to the help guide for the desktop environment you are using. Some sources recommend adding / etc / fstab, but you should avoid that, because failing to mount the directory may prevent your system from booting completely.
