I'm trying to mount Azure File Share in Oracle Linux 7.7 and it doesn't work in the latest kernel 4.1.12-124.31.1.1.el7uek.x86_64 (released Sep 2019).
I know that I must use encryption when connecting from outside of Azure region, but I'm not sure if the File Share is in the same region as VM as I don't have access to the Azure Portal.
I have tried mounting with options vers=3.0 and vers=2.1, both give permission denied. I have tried with smbclient and that works without any issues.
Does anyone know if this Oracle UEK kernel supports the cifs protocol needed by Azure File Share? This article mentions kernel 4.11 is needed, but I thought Oracle backported it in their kernel.
Also is there any way to see which protocol version smbclient used to connect? Using -d 3 I can only see that it used NTLMSSP.
you should try to install UEK5 kernel (built on 4.14.x upstream) To get this kind of thing in-place, you just need to enable the UEK5 Yum channel and then update the system with "yum update" or the only kernel -- if you prefer -- with "yum update kernel-uek". UEK4 (4.1.12.*) is based on 4.1.12 upstream and so it's quite older than 4.11. For further details related to UEK and OL releases, you can check this page:
