Is RPC 135 TCP or UDP?

Is RPC 135 TCP or UDP?

Microsoft Windows Networking Services Port 135 is used for RPC client-server communication, and ports 139 and 445 are used for authentication and file sharing. UDP ports 137 and 138 are used for local NetBIOS browser, naming, and lookup functions.

What is DCE RPC?

DCE/RPC, short for “Distributed Computing Environment / Remote Procedure Calls”, is the remote procedure call system developed for the Distributed Computing Environment (DCE).

What is RPC how RPC implemented in UDP protocol?

An RPC server consists of a collection of procedures that client may call by sending an RPC request to the server, along with the procedure parameters. They chose to have each server provide both a TCP and a UDP port for each program and each version.

What is UDP protocol?

User Datagram Protocol (UDP) – a communications protocol that facilitates the exchange of messages between computing devices in a network. It’s an alternative to the transmission control protocol (TCP). In a network that uses the Internet Protocol (IP), it is sometimes referred to as UDP/IP.

Which is the UDP port for DCE / RPC?

UDP: Typically, connectionless DCE/RPC uses UDP as its transport protocol. The well known UDP port for DCE/RPC EPMAP is 135. This transport is called ncadg_ip_udp. SMB: Connection oriented DCE/RPC can also use authenticated named pipes on top of SMB as its transport protocol.

Which is the current specification for DCE / RPC?

C706 DCE 1.1: Remote Procedure Call is dated 15/08/1997, which is the current and complete specification DCE/RPC can run atop a number of protocols, including: TCP: Typically, connection oriented DCE/RPC uses TCP as its transport protocol. The well known TCP port for DCE/RPC EPMAP is 135.

How does DCE / RPC listen for incoming calls?

A DCE/RPC server’s endpoint mapper (EPMAP) will listen for incoming calls. A client will call this endpoint mapper and ask for a specific interface, which will be accessed on a different connection. After that, the client can request calls to the server.

What does a DCE / RPC endpoint mapper do?

DCE/RPC is a specification for a remote procedure call mechanism that defines both APIs and an over-the-network protocol. A DCE/RPC server’s endpoint mapper (EPMAP) will listen for incoming calls.
