In this guide you'll learn how to mount a CIFS/SMB share on Ubuntu. Make sure you have your SMB server and credentials ready.
I advise you run the following as the root user. Especially step 4!
1. Installing package
sudo apt install cifs-utils
2. Create a folder
This is the folder where you will mount the share to.
3. Add entry to fstab
Open your fstab file
(/etc/fstab). And add something like this to the bottom of the file.
//SERVER_IP_ADDRESS/SHARE_NAME /mnt/backups cifs username=msusername,password=mspassword,iocharset=utf8 0 0

So create and open the file
/root/.smbcredentials using vim or nano. (Eg
sudo vi /root/.smbcredentials)
Save and close and then set the permissions that only root can read it.
sudo chmod 600 /root/.smbcredentials
You can verify it by writing:
sudo ls -al /root/.smbcredentials
If everything is correct you should see this:
Now open up your fstab again and replace the username and password with
Your file should look like this:
//SERVER_IP_ADDRESS/SHARE_NAME /mnt/backups cifs credentials=/root/.smbcredentials,iocharset=utf8 0 0
5. Actually mounting
If you reboot the folder will be mounted automatically. Of course we can manually mount it by entering the command
