Applies to

  • Linux smbclient

Issue

  • When downloading file use the following command, it fails with error "getattrib: NT_STATUS_NOT_SUPPORTED".

Example:

[root@centos-02 ~]# smbclient //10.128.242.240/vol_test -U domain\\user Password -D "\\qtree_test" -c "get test.txt"
getattrib: NT_STATUS_NOT_SUPPORTED

  • From packet perspective, smbclient sends SMB2_FILE_ALL_INFO when issuing the aforementioned command, but it's unsupported in Data ONTAP operating in 7-mode.
