[srslte-users] Running srsRAN on two VMs

[Scott Leonard]

Hi,

I'm new to srsRAN and am trying to run srsepc and srsenb on one VM while
running srsue on another VM.  The VMs are hosted on my Mac and networked in
the sense that they each have IP addresses and I can ping each of them from
the other.

I'm using zmq for the radio and I first tried out the provided run_lte.sh
script which runs everything on one VM with a separate network name
space for srsue.  That worked OK.

When I try it with two VMs, I can see the "srs_spgw_sgi" interface on the
srsepc/srsenb VM.  But I never see the "tun_srsue" interface on the srsue
VM.  The srsue log is pretty empty -- looks just like I'm running srsue
with no srsepc/srsenb running.

Any ideas about what I'm doing wrong?  Is there other networking stuff that
I have to set up in this case?

My commands are just the basic ones for zmq I think:
$ srsepc
$ srsenb --rf.device_name=zmq
--rf.device_args="fail_on_disconnect=true,tx_port=tcp://*:2000,rx_port=tcp://localhost:2001,id=enb,base_srate=23.04e6"

$ srsue --rf.device_name=zmq
--rf.device_args="fail_on_disconnect=true,tx_port0=tcp://*:2001,rx_port0=tcp://localhost:2000,id=ue,base_srate=23.04e6"


Thanks for any help.

Scott
