Mount CIFS share encrypted on RHEL7.5

Latest response

We have a need to mount encrypted shares on RHEL7.3
I see it is being worked on by RHEL I need an update on when it will be ready to implement

I'm running Red Hat Enterprise Linux Server release 7.5 Beta (Maipo).
I am mounting with "mount -t cifs -o seal,vers=3.0" options. How can I tell if the mount is indeed encrypted?

TIA!

Hi Kevin,

Simple answer: check the kernel version. Harder answer: snif traffic between the CIFS server and CIFS client and check the data for human readable patterns.

Thanks! I ran capture on port 445 (smb) and did see the encrypted data. Mounted with '-t cifs -o seal' options.

NOTE: 'Seal' option is not listed in man page. https://bugzilla.redhat.com/show_bug.cgi?id=1495572
