Q. I have access rights to one of the remote server through SSH protocol and there is no File share services such as Samba, NFS or FTP etc which are enabled on the server. Now I want to mount data from that remote server, is it possible to mount remote folders?
A. The answer to this is yes, We can share data/mount folder on a local machine by using just SSH protocol. This can be done by using FUSE(Filesystem in USErspace) which support SSH and FTP file systems. This post is in response to conversation which I had with one our users two days back. the question he asked about ftp is “I want to transfer one latest file from my ftp server and I want to automate this task through shell script to download latest file from my FTP server, And I don’t know what is the Operating System at server end(This is ultimate sentence I hear from the user today in my office 🙂 )“. Let’s prepare our machine on how to mount a remote folder by using SSH protocol.
Step1: Installing Package
apt-get install sshfs
rpm -ivh fuse-sshfs-1.8-1.el5.rf.i386.rpm
Step2: Once the package is installed we have to create a mount point and mount our server data using sshfs command, for which we require username/password. Here are my details for this task.
My Username: root My password: redhat My Server: 10.233.10.212 My mount point: /mnt/ssh
Now create the mount point and mount SSH account data.
#mkdir /mnt/ssh #sshfs email@example.com:/ /mnt/ssh/ firstname.lastname@example.org's password:
Step3: The above command will mount my root directory in 10.233.10.212 server. Testing our setup
Check if you are able to see data
bin cdrom data etc initrd.img lib media opt root selinux sys tmp var vmlinuz.old boot cmdb-bkp dev home initrd.img.old lost+found mnt proc sbin srv test usr vmlinuz
What about df -hs command output?
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 12G 8.4G 2.5G 78% /
/dev/sda6 80G 43G 34G 56% /var
/dev/sda5 2.0G 41M 1.8G 3% /home
/dev/sda1 99M 12M 83M 12% /boot
tmpfs 506M 0 506M 0% /dev/shm
email@example.com:/ 1000G 0 1000G 0% /mnt/ssh
Step4: So what about mounting it permanently?. We can do it by editing fstab file in /etc folder
go to last line and type below line
firstname.lastname@example.org:/ /mnt/ssh fuse defaults 0 0
Save the file and exit. Now run mount -a to update the fstab file state to kernel.
Note: Its not advisable to write passwords in human readable files like /etc/fstab.
Let me explain what entry in fstab indicates. We are mentioning mount user root data which is located on 10.233.10.212 server on to /mnt/ssh using fuse file system with default settings.
Step5: What about unmounting this drive?
Enjoy new learning of mounting a folder using SSH protocol.
