	SMB Trans Vs SMB Write / SMB Read by Shirish Pargaonkar :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message In Samba, can a QNmPipeInfo functionality be implemented using SMB Write and SMB Read instead of SMB Trans with command QNmPipeInfo? I can send DCE RPC bind using SMB Write and read the bind ack using SMB Read instead of SMB Trans TransactNmPipe. I was wondering if similar could be done to implement various named pipe functions such as SetNmPHandState, QNmPHandState, and WaitNamedPipe by sending an appropriate blob. _______________________________________________ linux-cifs-client mailing list linux-cifs-client@... https://lists.samba.org/mailman/listinfo/linux-cifs-client

Hmmm. Not that I know of. Those transfer extra metadata that is not really inline.

	Re: SMB Trans Vs SMB Write / SMB Read by Shirish Pargaonkar :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message OK. I was thinking why should named pipe concern itself with how a blob has arrived i.e. either via smbtrans or via smbwrite? For example, in case of QNmPipeInfo, if the blob can contain necessary info such as function name (0x26) and Infolevel (0x1), named pipe should have a response ready to be read.

Please ask Microsoft (and maybe in particular Chris Hertel) about this particular isse. Unfortunately I don't have access to Microsoft source code, so I don't really know what the ways to these functions are.

	Re: SMB Trans Vs SMB Write / SMB Read by Shirish Pargaonkar :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Alright. I thought Samba server would have similar functionality as far as named pipes are concerned. Thanks.

And all we've seen so far for these pipe metaoperations is trans2 requests. We just haven't seen anything else on the wire, and there is virtually no documentation (yet?) on this topic. As I said, we don't have access to Windows source code, so we can only reply to what the clients have so far sent us.
