Re: Connecting to NSO running in Docker using Java maapi api expected 9 bytes from socket, only got -1

By default, NSO listens to 127.0.0.1:4569 for IPC connections. See this excerpt from the ncs.conf man page:

/ncs-config/ncs-ipc-address/ip (ipv4-address | ipv6-address) [127.0.0.1]
The IP address which NCS listens on for incoming connections from the Java library

/ncs-config/ncs-ipc-address/port (port-number) [4569]
The port number which NCS listens on for incoming connections from the Java library

Did you configure the ip to match what you expect to see from your port forwarding setup?

Hi allen,

thank you for your response. Let me update ncs.conf and try it out
