Azure File Storage is a service that offers shared File Storage for any OS that implements the supported SMB Protocol. Since GA we supported both Windows and Linux. However, on premises access was only available to Windows. While Windows customers widely use this capability, we have received the feedback that Linux customers wanted to do the same. And with this capability Linux access will be extending beyond the storage account region to cross region as well as on premises. Today we are happy to announce Azure File Storage on-premises access from across all regions for our first Linux distribution – Ubuntu 17.04. This support is right out of the box and no extra setup is needed.
How to Access Azure File Share from On-Prem Ubuntu 17.04
Steps to access Azure File Share from an on-premises Ubuntu 17.04 or Azure Linux VM are the same.
Step 1: Check to see if TCP 445 is accessible through your firewall. You can test to see if the port is open using the following command:
nmap.file.core.windows.net
Step 2: Copy the command from Azure Portal or replace <storage account name>,
sudo mount -t cifs //.file.core.windows.net/ -o vers=3.0,username= ,password= ,dir_mode=0777,file_mode=0777,sec=ntlmssp
Step 3: Once mounted, you can perform file-operations

Other Linux Distributions
Backporting of this enhancement to Ubuntu 16.04 and 16.10 is in progress and can be tracked here: CIFS: Enable encryption for SMB3. RHEL is also in progress. Full-support will be released with next release of RHEL.
