Hi all, OPC is a standard that specifies a collection of DCOM interfaces heavely used in the industrial automation domain. (http://www.opcfoundation.org) I would like to access these OPC objects that run in Windows from Linux computers, using the DCOM framework. Instead of implementing DCOM from scratch for Linux, I was considering 'stealing' some code off the SAMBA project relating to the DCOM rpc stuff. Could anybody please confirm that SMB really does run over DCOM, in other words, does the SAMBA code include some kind of implementation of the DCOM protocols? If so, could you give me sugestions on how I could go about this? Where can I get some info regarding the internal functions that I need to call to make DCOM rpc invocations? At the moment I was considering starting off by extending the rpcclient utility and using some of the already implemented services as a guide. I have been browsing this code, nevertheless, some of the details still escape me. For example, what is a pipe, and what do the pipe_idx variables contain? Any help would be higly apreciated! Thanks in advance, Mario de Sousa

DCOM runs over DCE/RPC, which /can/ run over SMB. I have been working on an initial implementation of DCOM in Samba4. It is still in the initial phase of development (some RPC stuff is there), but let me know if you're interested in helping out.
