Context
I'm following this tutorial: https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html
When I get to the part where I have to execute the flow graph, the gnuradio terminal gives me this error:
The only thing I'm doing different from the tutorial is that I'm not running everthing on localhost. I'm trying to replicate the tutorial using two different machines (one for the core and gNB (IP 192.168.0.108), the other for the UEs (IP 192.168.0.206)). I'm running the gnuradio command on the same host that is running the gNB.
My UEs run o a docker with Ubuntu 22.04 as the base image. Communication between the UE and Core works when I follow the tutorial with a single UE.
Configs
All configs files I'm using are the defaults files from the srsRAN Project and the files provided on the tutorial, so I will share only the parts I've changed.
open5gs.env
gNB config:
UE1 config:
UE2 config
UE3 config
multi_ue_scenario.py
Image of the graph
I run my container with the following arguments:
docker run --rm -it --network host --name ue --privileged srsran:latest bash
Questions
Why it doesn't connect? Did I miss something/did something wrong with the configs? If so, what should I fix? Or how can I tackle (debug) this problem?
Further info
Each host can ping the other
