[MS-SMB] System.InvalidOperationException: unexpected end of channel stream: expected 1 more byte

[tymok]

Hello.

I got some error messages while running MS-SMB testsuites.
With the test result, I found that many exceptions "System.InvalidOperationException: unexpected end of channel stream: expected 1 more byte(s)" occured with my SMB server implementation.
Could you check and inform why the error occured and what it means?

Hi, Taeyang

I looked into the errors and it seems that the exception is thrown because the test suite SDK failed to decode SMB Negotiate response packet returned by your SMB server, and the response should contain one more byte as the SDK expects while reading the stream, thus the assertion here failed.

Since I cannot debug to get more information, here I have the windows network capture for "TraditionalTestCase_Disconnect_14_Case

", which run pass on the windows test environment, you can take it as a reference to see the message differences
TraditionalTestCase_Disconnect_14_Case.matp.zip
. Capture with Microsoft Message Analyzer which you can download from website.

Thanks,
Lu
