In short what I which to know is whether pipes can be used across internet connection.
That is , if process A is running on system A creates a named pipe, can process B on system B connect to the named pipe is the only thing that links the two system together is the internet?

Sockets are your best bet for communicating over the internet... and they also have the added plus that they still work locally (intranet or even on the same machine).

Named pipes require RPC connections, so the two computers need to be able to connect with out firewalls.

It is possible to connect via the internet if you are connecting to the IP address, and the RPC ports are open (at least : 137,139,447).

My 5.

However, I worked with named pipes only recently, but on the same machine (communication between .NET - C++ processes), and never tried it via network but clearly remember that it was indicated in documentation as a valid option. That said, your answer might not be descriptive enough. If I was OP, I would ask you some additional information on how to establish such connection between different hosts, or a reference.

So, OP may want to ask you about some clarification on this matter.

Named pipes are definitely a pain in the nether regions, I used them once for speed but it wasn't worth the maintenance cost for operations as they require authentication even before connecting. I have switched to TCP since then (my WCF Killer article).

Thanks Sergey.

So, would YOU want to open your firewalls? Would the remote site? I doubt it. Named pipes are intended for intranets and shouldn't be used across the internet.

Mehdi Gholam 29-Nov-11 14:23pm

Absolutely not, I agree completely, as I was saying to SA they even require authentication for non domain computers before connecting.

Named pipes are not routable on the internet.

EDIT ==================

I don't know why this was 1-voted. The information is factual.
