[srsran-users] srsRAN 4G with ZMQ Using Two Linux PCs

[Chao-Hwa Chen]

Hi all,

I followed the document here
https://docs.srsran.com/projects/4g/en/latest/app_notes/source/zeromq/source/index.html
and made the EPC/ENB/UE work with one Linux laptop.

Up next, I want to do the same thing with 2 Linux PCs. One with EPC/ENB and
the other with UE only. The two Linux PCs have different IP addresses.

At the EPC/ENB PC, I login as root and type
./srsepc/src/srsepc
at the EPC and
./srsenb/src/srsenb --rf.device_name=zmq
--rf.device_args="fail_on_disconnect=true,tx_port=tcp://*:2000,rx_port=tcp://(UE
IP Address):2001,id=enb,base_srate=23.04e6"
at the ENB.

At the UE PC, I also login as root and type
./srsue/src/srsue --rf.device_name=zmq
--rf.device_args="tx_port=tcp://*:2001,rx_port=tcp://(ENB IP
Address):2000,id=ue,base_srate=23.04e6" --gw.netns=ue1
at the UE.

I can get the sync, but the console shows the message of "failed to
setup/configure GW interface" and I don't see the IP address 172.16.0.2
from ifconfig.

What should I do to fix the problem?

Thanks a lot in advance.
