Ecora Patch Manager FAQ

Question:  What Ports are used by Patch Manager?

Answer:  Ports:

NetBIOS:

NetBIOS ports 137, 138 and 139 TCP & UDP

137 NetBios Name Service
138 Datagram Service
139 Session Service

SMB over IP port 445 TCP

Endpoint Mapper port 135

RPC port negotiation

RPC "named-pipe" connections can be constructed between the two systems
at "unprivileged" port numbers, those greater than 1024. This requires
RPC negotiation that can include port 135 (mapping the two endpoints).
RPC ports are >1024 and purposefully random to avoid spoofed connections.
