meaning of smb seek

[Christopher R. Hertel]

I wish I had answers for you, but I don't (which is why I am interested in
what you find out).

Do you receive SEEK commands from clients?  It's possible that it's not ever
used.  The SMB_COM_COPY is another example.  We found that it didn't work
properly on most servers we tested and it seems that Windows clients don't
call it.
