And to run srsUE on it's own machine. But for the eNB to connect to the EPC I need gtp_bind_addr and s1c_bind_addr to be the same.</p><p style="white-space: pre-wrap; word-wrap: break-word;">See here:</p><p style="white-space: pre-wrap; word-wrap: break-word;">[enb]<br># need hex value here for enb_id due to bug: https://github.com/srsLTE/srsLTE/issues/485<br>enb_id = 0x19b<br>mcc = 901<br>mnc = 70<br>mme_addr = 127.0.1.100<br>gtp_bind_addr = 127.0.1.1<br>s1c_bind_addr = 127.0.1.1<br>n_prb = 100<br>tm = 1<br>nof_ports = 1</p><p style="white-space: pre-wrap; word-wrap: break-word;">You are right that if I put just "addr" as s1c_bind_addr and set the run_addr to 127.0.1.1, I can get the above mentioned config and the eNB attached to the EPC. But the same run_addr is also used for the ZMQ radio and this is then not working. Perhaps UHD works.</p><p style="white-space: pre-wrap; word-wrap: break-word;">This is the stdout of srsUE:<br>Reading configuration file /osmo-gsm-tester-srsue/srsue/srsue.conf...</p><p style="white-space: pre-wrap; word-wrap: break-word;">Built in Release mode using commit 34bc192f7 on branch build_branch.</p><p style="white-space: pre-wrap; word-wrap: break-word;">Opening 1 channels in RF device=zmq with args=tx_port0=tcp://10.12.1.206:2001,tx_port1=tcp://10.12.1.206:2003,tx_port2=tcp://10.12.1.206:2005,tx_port3=tcp://10.12.1.206:2007,rx_port0=tcp://127.0.1.1:2000,rx_port1=tcp://127.0.1.1:2002,rx_port2=tcp://127.0.1.1:2004,rx_port3=tcp://127.0.1.1:2006,rx_freq0=2630e6,tx_freq0=2510e6,id=ue,base_srate=23040000<br>CHx base_srate=23040000<br>CHx id=ue<br>Current sample rate is 1.92 MHz with a base rate of 23.04 MHz (x12 decimation)<br>CH0 rx_port=tcp://127.0.1.1:2000<br>CH0 rx_freq=2630e6<br>CH0 tx_port=tcp://10.12.1.206:2001<br>CH0 tx_freq=2510e6</p><p style="white-space: pre-wrap; word-wrap: break-word;">You see that ZMQ radio tries to receive from this localhost address, but it should receive from the external IP.</p><p style="white-space: pre-wrap; word-wrap: break-word;">So in summary, this patch is needed and cant be deleted.</p><p><a href="https://gerrit.osmocom.org/c/osmo-gsm-tester/+/18583">View Change</a></p><ul style="list-style: none; padding: 0;"></ul><p>To view, visit <a href="https://gerrit.osmocom.org/c/osmo-gsm-tester/+/18583">change 18583</a>.
