First generic "epc",<br> afterwards the specific enb type.<br>* A new scenario is added to select the EPC type to use. srsEPC is the<br> default unless stated by an scenario.<br>* AmarisoftEPC delegates setup of the tun IP address to an "ifup"<br> script. As a result, since we run without root permissions (ony with<br> CAP_NET_ADMIN), the ifup script itself is unablet o set the IP<br> address. To solve this, we introduce a new osmo-gsm-tester helper<br> script which must be installed in the slave node which can be called<br> through sudo to increase privileges to do so.<br><br>With this commit, I can already get srsUE<->amarisoftENB<->amarisoftEPC<br>to pass ping and iperf3 4g tests.<br><br>Change-Id: Ia50ea6a74b63b2d688c8d683aea11416ad40a6d3<br>---<br>M example/defaults.conf<br>A example/scenarios/cfg-epc-type@.conf<br>A src/osmo_gsm_tester/amarisoft_epc.py<br>A src/osmo_gsm_tester/epc.py<br>M src/osmo_gsm_tester/resource.py<br>M src/osmo_gsm_tester/srs_epc.py<br>M src/osmo_gsm_tester/suite.py<br>A src/osmo_gsm_tester/templates/amarisoft_ltemme.cfg.tmpl<br>A utils/bin/osmo-gsm-tester_amarisoft_ltemme_ifup.sh<br>A utils/sudoers.d/osmo-gsm-tester_amarisoft_ltemme_ifup<br>10 files changed, 451 insertions(+), 21 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.osmocom.org:29418/osmo-gsm-tester refs/changes/90/17690/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/example/defaults.conf b/example/defaults.conf</span><br><span>index bcd1fa2..56a41e5 100644</span><br><span>--- a/example/defaults.conf</span><br><span>+++ b/example/defaults.conf</span><br><span>@@ -93,12 +93,17 @@</span><br><span> trx_list:</span><br><span> - nominal_power: 25</span><br><span> </span><br><span style="color: hsl(0, 100%, 40%);">-srsepc:</span><br><span style="color: hsl(120, 100%, 40%);">+epc:</span><br><span style="color: hsl(120, 100%, 40%);">+ type: srsepc</span><br><span> mcc: 901</span><br><span> mnc: 70</span><br><span style="color: hsl(120, 100%, 40%);">+srsepc:</span><br><span> rlc_drb_mode: UM</span><br><span> enable_pcap: false</span><br><span> </span><br><span style="color: hsl(120, 100%, 40%);">+amarisoftepc:</span><br><span style="color: hsl(120, 100%, 40%);">+ license_server_addr: 10.12.1.139</span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span> enb:</span><br><span> mcc: 901</span><br><span> mnc: 70</span><br><span>diff --git a/example/scenarios/cfg-epc-type@.conf b/example/scenarios/cfg-epc-type@.conf</span><br><span>new file mode 100644</span><br><span>index 0000000..89b7fba</span><br><span>--- /dev/null</span><br><span>+++ b/example/scenarios/cfg-epc-type@.conf</span><br><span>@@ -0,0 +1,3 @@</span><br><span style="color: hsl(120, 100%, 40%);">+config:</span><br><span style="color: hsl(120, 100%, 40%);">+ epc:</span><br><span style="color: hsl(120, 100%, 40%);">+ type: ${param1}</span><br><span>diff --git a/src/osmo_gsm_tester/amarisoft_epc.py b/src/osmo_gsm_tester/amarisoft_epc.py</span><br><span>new file mode 100644</span><br><span>index 0000000..0361f54</span><br><span>--- /dev/null</span><br><span>+++ b/src/osmo_gsm_tester/amarisoft_epc.py</span><br><span>@@ -0,0 +1,203 @@</span><br><span style="color: hsl(120, 100%, 40%);">+# osmo_gsm_tester: specifics for running an SRS EPC process</span><br><span style="color: hsl(120, 100%, 40%);">+#</span><br><span style="color: hsl(120, 100%, 40%);">+# Copyright (C) 2020 by sysmocom - s.f.m.c.
