Error: O-RAN NearRT-RIC and xApp - Failed to create SCTP gateway #255

Closed raul-parada closed 1 year ago

raul-parada commented 1 year ago

Issue Description

Error to connect with nearRT-RIC

Setup Details

Ubuntu 22.04

Expected Behavior

As mentioned in the tutorial:

--== srsRAN gNB (commit 611bf17fe) ==--

Connecting to AMF on 10.53.1.2:38412
Available radio types: zmq.
Connecting to NearRT-RIC on 127.0.0.1:36421
Cell pci=1, bw=10 MHz, dl_arfcn=368500 (n3), dl_freq=1842.5 MHz, dl_ssb_arfcn=368410, ul_freq=1747.5 MHz

==== gNodeB started ===

Actual Behaviour

Lower PHY in executor blocking mode.

--== srsRAN gNB (commit 5e6f50a20) ==--

Failed to bind SCTP socket to 10.53.1.1:0. Cannot assign requested address
srsGNB ERROR: Failed to create SCTP gateway.

Aborted (core dumped)

Steps to reproduce the problem

1- Run flexric:

./flexric/build/examples/ric/nearRT-RIC
Setting the config -c file to /usr/local/etc/flexric/flexric.conf
Setting path -p for the shared libraries to /usr/local/lib/flexric/
[NEAR-RIC]: nearRT-RIC IP Address = 127.0.0.1, PORT = 36421
[NEAR-RIC]: Initializing 
[NEAR-RIC]: Loading SM ID = 147 with def = ORAN-E2SM-KPM 
[NEAR-RIC]: Loading SM ID = 144 with def = PDCP_STATS_V0 
[NEAR-RIC]: Loading SM ID = 146 with def = TC_STATS_V0 
[NEAR-RIC]: Loading SM ID = 148 with def = GTP_STATS_V0 
[NEAR-RIC]: Loading SM ID = 142 with def = MAC_STATS_V0 
[NEAR-RIC]: Loading SM ID = 145 with def = SLICE_STATS_V0 
[NEAR-RIC]: Loading SM ID = 143 with def = RLC_STATS_V0 
[iApp]: Initializing ... 
[iApp]: nearRT-RIC IP Address = 127.0.0.1, PORT = 36422
fd created with 6

2- Execute gnb (then I got the error mentioned above)

Additional Information

I've followed all the steps succesfully from https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html

Do you run both gnb and ric on the same host?

Please try to set bind_addr

e2:
  enable_du_e2: true                # Enable DU E2 agent (one for each DU instance)
  e2sm_kpm_enabled: true            # Enable KPM service module
  addr: 127.0.0.1                   # RIC IP address
  bind_addr: 127.0.0.1              # A local IP that the E2 agent binds to for traffic from the RIC
  port: 36421                       # RIC port

Yes, everything in the same host. I still get the same error.

When executing gnb ``` cd ./srsRAN_Project/docker docker-compose up --build 5gc


, I receive this message:

In which folders should I paste the files gnb_zmq.yaml and ue_zmq.config?
pgawlowicz commented 1 year ago

5gc cannot be started as there is already sth running on port 3000. Did you try to run Open 5GC twice?

raul-parada commented 1 year ago

After restarting the PC and it runs successfully. Now, the gnb runs, however, the UE doesn't receive IP

I'm missing something?

Try

sudo ip netns add ue1
