Issue Description

Hi, I am trying to run the Ethernet demo to allow Realsense cameras D435 available over the network. I am following this document: https://dev.intelrealsense.com/docs/open-source-ethernet-networking-for-intel-realsense-depth-cameras. However, I get the following error when I connect to the camera over the network from my linux host running the realsense-viewer.

"RealSense error calling: out of range value for argument "def" - this when I try to connect to the IP address of the eth0 interface on the Raspberry Pi. The linux Host is on 192.168.8.2 and the Rpi is on 192.168.8.102 ... both can ping each other.

The librealsense.log on the linux host as the following info:

Also, the RsServer.cpp ignores the interface address passed in the command line: rs-server -i 192.168.8.102

if (arg_address.isSet()) 
        {
            ReceivingInterfaceAddr = our_inet_addr(arg_address.getValue().c_str());
        }

ReceivingInterfaceAddr is not used elsewhere in the code.

Hi kochhalm,
When running the viewer on ubuntu system (host), you also need to install required package by following instruction
https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md
similar issue reported
#7056
to allow the kernel can support Realsense camera's data format.

once all required packaged are installed, you can plug camera directly into your ubuntu PC's USB3 port to see the viewer can stream the camera properly then move to next step that access the camera remotely..

or you can running viewer on win10 PC which no need install additional package
to access the raspberry PI4 rs-server
to see if the raspberry Pi4 is also installed properly.

[RealSenseSupport]

as to rs-server -i option, as you find out, there is no function implement for it yet.
you just need to launch rs-server
the client should already able to access it through viewer as long as the IP address input to the viewer is same the fixed one you configure to your raspberry

Dear Kochholm,
had you been able to run the rs-server on your Raspberry Pi4?

So how to solve the issue?

[zorderjohn]

This issue happened to me when the firmware of the camera was not compatible with the SDK version.

To solve it, you can either

• Set firmware version 5.12.7.100 to the camera to work with the SD flash image they provide.
• Update firmware to latest version and also build and install the newest librealsense available to your Raspbian/Ubuntu OS
