Unable to retrieveFile() - 'FileStreamInformation' not supported by SMB server
viralmutant opened this issue · 5 comments
I was trying file create/retrieve/delete against an SMB server, over SMB2.
Though storeFile and deleteFiles are working fine, the retrieveFile fails at infoCB
Wireshark analysis shows that FileStreamInformation is not supported by the SMB server.
Since windows client works fine against the server so I would assume that it's OK that the server may not support this operation.
How to fix this and get it working? I certainly can't change SMB server code
May I know what is your SMB server?
Another method is to disable SMB2 in pysmb and use SMB1 for communication.
from smb import smb_structs
smb_structs.SUPPORT_SMB2 = False
# ... Create your pysmb object here
May I know what is your SMB server?
It's Likewise server
Unfortunately, I don't have any experience with it as Samba is a more popular choice.
I think the software has been renamed to PowerBroker some years ago.
Please let me know if switching to SMB1 works for you. Thanks.

Yes, switching to SMB1 resolved it
Thanks
For the record, I was able to fix this for SMB2 as well
Just changed the FILE_INFO_CLASS from FILE_STREAM_INFORMATION to FILE_STANDARD_INFORMATION to get the length of file, in smb/base.py file:
936 def createCB(create_message, **kwargs):
937 messages_history.append(create_message)
938 if create_message.status == 0:
939 m = SMB2Message(SMB2QueryInfoRequest(create_message.payload.fid,
940 flags = 0,
941 additional_info = 0,
942 info_type = SMB2_INFO_FILE,
943 # file_info_class = 0x16, # FileStreamInformation [MS-FSCC] 2.4
944 file_info_class = 0x5,
945 input_buf = b'',
946 output_buf_len = 4096))
