I wrote about using the smbutil for DFS in Lion awhile back. I haven’t needed to write anything else as it hadn’t changed since. The statshares option has an -m option to look at a mount path for showing the path to the mount (e.g. if the mount is called krypted this should be something like /Volumes/krypted):
smbutil statshares -m /Volumes/krypted
When run, you see a list of all the attributes OS X tracks for that mount path, including the name of the server, the user ID (octal), how SMB negotiated an authentication, what version of SMB is running (e.g. SMB_1), the type of share and whether signing, extended security, Unix and large files are supported.
Additionally, if you’d like to see the attributes for all shares, use the -a option after statshares:
smbutil statshares -a
Overall, this is a nice health check type of verb to the smbutil command that can be added to any monitoring or troubleshooting workflow.
