Volker, To answer your follow-up question, the Offset is relative to the header, but for SMB1 compounding there is a single header and the AndXOffset is in the request parameters. As such, the offset is from the beginning of the packet.

This would apply to SMB2 chaining, where each request is indeed self-contained. This is not the case in SMB1, where there is only one SMB header for multiple SMB commands. How does this fit your description? Volker _______________________________________________ cifs-protocol mailing list [email protected] https://lists.samba.org/mailman/listinfo/cifs-protocol
