Hello, maybe you have already another program listening on udp port 4997.
Try ss -unlp | grep ':4997'
to check this.
您好,您可能已经有另一个程序在监听 udp 端口 4997。 尝试
ss -unlp | grep ':4997'
检查一下。
I tried to execute the command, but nothing happened
Ok, in config/free5gc-gnb.yaml
have you modified the IP Address for linkIp
? It is the IP your gNB will listen on for Radio Link Simulation. Please double check your gNB's host has an interface up with this address set.

linkIp: 10.100.200.100 # gNB's local IP address for Radio Link Simulation (Usually same with local IP) ngapIp: 172.28.82.134 # gNB's local IP address for N2 Interface (Usually same with local IP) gtpIp: 172.28.82.134 # gNB's local IP address for N3 Interface (Usually same with local IP)

Hi @niyingdong @louisroyer I'm also facing the same issue, Did you get the solution for the above?
when executing ss -unlp | grep ':4997'
I'm getting below one
Croot@ueransim-gnb-deployment-ddf87f74c-bntvq:/UERANSIM# ss -unlp | grep ':4997'
UNCONN 0 0 0.0.0.0:4997 0.0.0.0:* users:(("nr-gnb",pid=1,fd=4))
and this is when firing ps -ax | grep nr-gnb
root@ueransim-gnb-deployment-ddf87f74c-bntvq:/UERANSIM# ps -ax | grep nr-gnb
1 ? Ssl 0:13 ./build/nr-gnb -c ./config/free5gc-gnb.yaml
355 ? Z 0:00 [nr-gnb] <defunct>
1021 pts/2 S+ 0:00 grep --color=auto nr-gnb
Waiting for your quick reply!!

pls solve this
Hello @niyingdong @louisroyer,
Did you manage to fix this problem?
I am setting for gnbcfg.yaml file the same IP for the three values linkIp, ngapIp, gtpIp.
Still, I can register and deregister a UE but I am not sure why this error still appears.
and regarding this command I can see the right IP for the gnb:
@aligungr do you have any idea about this error?
Thank you for your help. Nathalie Wehbe
@nathalie21005 were you able to solve the issue?
hi @jamjad333,
yes, the problem is that when you run the free5gc-compose that includes ueransim, it will automatically run the gnb you don't need to run the gnb again inside the ueransim container. Run free5gc-compose Go to ueransim container and run ./nr-cli --dump Once you run the previous command you will see the gnb name
@nathalie21005 but i am not using docker,i compiled using source code
@jamjad333 which version are you using? and how are you running free5gc?
@nathalie21005 i have deployed open5gs core v2.4 using source code and i am trying to connect with srsRAN
I don't know about open5gs but make sure to run the gnb file of open5gs not free5gc in ueransim
