SSHFS (Secure SHell FileSystem) for Mounting Remote Linux Filesystems
The main purpose of writing this article is to provide a step-by-step guide on how to mount remote Linux file system using SSHFS client over SSH. This article is useful for those users and system administrators who want to mount remote file system on their local systems for whatever purposes. We have practically tested by installing SSHFS client on one of our Linux system and successfully mounted remote file systems. Before we go further installation let’s understand about SSHFS and how it works.
What Is SSHFS?
SSHFS stands for (Secure SHell FileSystem) client that enable us to mount remote filesystem and interact with remote directories and files on a local machine using SSH File Transfer Protocol (SFTP). SFTP is a secure file transfer protocol that provides file access, file transfer and file management features over Secure Shell protocol. Because SSH uses encryption while transferring files over the network from one computer to another computer and SSHFS comes with built-in FUSE (Filesystem in Userspace) kernel module that allows any non-privileged users to create their file system without modifying kernel code.
Before we move further with the installation process, We’d like to tell you that the below installation also works on all RedHat based distributions like RHEL 6.3/6.2/6.1/6/5.8, CentOS 6.3/6.2/6.1/6/5.8 and Fedora 17,16,15,14,13,12.
Install SSHFS in RHEL, CentOS and Fedora
Step 1: Installing SSHFS
By default sshfs packages does not exists on all major Linux distributions, you need to enable epel repository under your Linux systems to install sshfs with the help of Yum command with their dependencies.
# yum install sshfs
Step 2: Creating SSHFS Mount Directory
Once the sshfs package installed, you need to create a mount point directory where you will mount your remote file system. For example, we have created mount directory under /mnt/tecmint.
# mkdir /mnt/tecmint
Step 3: Mounting Remote Filesystem with SSHFS
Once you have created your mount point directory, now run the following command as a root user to mount remote file system under /mnt/tecmint. In your case the mount directory would be anything. The following command will mount remote directory called /home/tecmint under /mnt/tecmint in local system. (Don’t forget replace x.x.x.x with your IP Address and mount point).
# sshfs email@example.com:/home/tecmint/ /mnt/tecmint
Step 4: Verifying Remote Filesystem is Mounted
If you have run the above command successfully without any errors, you will see the list of remote files and directories mounted under /mnt/tecmint.
# cd /mnt/tecmint # ls
[root@ tecmint]# ls 12345.jpg ffmpeg-php-0.6.0.tbz2 Linux news-closeup.xsl s3.jpg cmslogs gmd-latest.sql.tar.bz2 Malware newsletter1.html sshdallow epel-release-6-5.noarch.rpm json-1.2.1 movies_list.php pollbeta.sql ffmpeg-php-0.6.0 json-1.2.1.tgz my_next_artical_v2.php pollbeta.tar.bz2
Step 5: Checking Mount Point with df -hT Command
If you run df -hT command you will see the remote file system mount point.
# df -hT
[root@tecmint]# df -hT Filesystem Type Size Used Avail Use% Mounted on /dev/cciss/c0d0p2 ext3 75G 21G 51G 29% / /dev/cciss/c0d0p5 ext3 24G 21G 1.5G 94% /home /dev/cciss/c0d0p3 ext3 29G 25G 2.6G 91% /data /dev/cciss/c0d0p1 ext3 289M 22M 253M 8% /boot tmpfs tmpfs 252M 0 252M 0% /dev/shm firstname.lastname@example.org:/home/midday/ fuse 457G 129G 305G 30% /mnt/tecmint
Step 6: Mounting Remote Filesystem Permanently
To mount remote filesystem permanently, you need to edit the file called /etc/fstab. To do, open the file with your favorite editor.
# vi /etc/fstab
Go to the bottom of the file and add the following line to it and save the file and exit. The below entry mount remote server file system with default settings.
email@example.com:/home/tecmint/ /mnt/tecmint fuse defaults 0 0
Next, you need to update the fstab file to reflect the changes.
# mount -a
Step 7: Unmounting Remote Filesystem
To unmount remote filesystem, jun issue the following command it will unmount the remote file system.
# umount /mnt/tecmint
