Debugging security with sectrace

A new command called "sectrace" can help debug security problems (e.g. user cannot chown a file with NT ACL).

sectrace add -a -path /vol/software

will produce meesages such as these:

Sun Feb 1 13:10:52 IST [jim: sectrace.filter.allowed:info]: [sectrace index: 2] Access allowed because 'Synchronize, Read Attributes' permission (0x100080) is granted on file or directory (Access allowed by an explicit access control entry) - Status: 1:58720452:0:0 - 10.1.20.107 - NT user name: support\administrator - UNIX user name: root(0) - Qtree security style is NTFS and NT ACL is set on file/directory - Path: /vol/software/

Typically there is no need to use -a since you only want to debug DENY replies.

Migrate Data with Robocopy

robocopy C:\ \\\ /MIR /COPYALL /Z /LOG:C:\Robocopy.txt /R:0 /W:0 /NP /XD RECYCLER "System Volume Information" ~snapshot

Some explanations:

  • /Z - Restartable Mode - If Robocopy is stopped, then restarted, partially copied files are picked up and incrementally copied.
  • /B - Backup Mode - In some cases it is advised to also add the /B (Backup Mode) option to copy files in backup mode. This option leverages the Windows NT "backup mode" feature, allowing files to be copied using the Backup Operator rights.

OK, I'm proud of it - I have a webcast with Tony Asaro about next-generation filesystems and enterprise search - and how we at Exanet are changing the map:
