Example Usage #4

nickvsnetworking · 2019-11-25T06:13:52Z

Hi S1AP team,
Keen to start using this,
I've compiled from source, and I see both libraries compiled (TestCntlrApp/lib and Trfgen/lib)

Next question is how do I use it? I had a read through the source code and found the example/sample in Trafgen and made that executable, but I just get back an error

example/sample: error while loading shared libraries: libtrfgen.so: cannot open shared object file: No such file or directory

Regardless of where I put libtrfgen.so

Is anyone able to give me a shove in the right direction?

We have been using S1ap-tester for integration tests with Magma EPC (https://github.com/facebookincubator/magma). Detailed instructions on running example scenarios are here: https://github.com/facebookincubator/magma/blob/master/docs/readmes/lte/s1ap_tests.md

infinitydon · 2020-01-08T22:04:25Z

@ssanadhya - The detailed example is tied to using Magma vagrant VMs, is it possible to get an example of how to use S1APTester with a generic EPC stack (MME,SGW,PGW)?

The current README only shows how to compile the modules.

I am trying s1APTester with open5gs epc.

I edit file nbAppCfg.txt to set ENB_IP_ADDR, SCTP_IP_ADDR (to the IP of S1APTester machine) and MME_ADDR and PLMN_ID.
I have also changed the UE_ETH_INTF.

Still no luck. Wireshark shows SCTP INIT messages from S1APTester to MME and SCTP INIT ACK from MME to S1APTester repeating.

@cgiraldo , no exchange of SCTP complete signalling ? so far I have not faced SCTP related issue with simulator with my EPC. I have not tried with open5gs EPC.

infinitydon · 2020-07-10T19:30:19Z

@vimal2828 Please can you share how you were able to get this to work. If possible a step by step procedure on how to configure s1APTester to work EPC (apart from Magma)..

vimal2828 · 2020-07-11T04:39:10Z

@infinitydon , please find the steps that I used to bring up the S1AP simulator and integration with my EPC.

Compile TestCntlrApp and copy the generated shared library libtfw.so in directory /usr/lib
Compile Trfgen and copy the generated shared library libtrfgen.so in in the directory /usr/lib
Compile TestCntlrStub and get the binary testCntrlr

Note: In step 3, if compilation fails then need to do some changes in code either at TestCntlrStub or TestCntlrApp.
There is a mismatch in structure definition along with another where one variable is used but not defined.
For the differences please refer the pull request https://github.com/facebookexperimental/S1APTester/pull/22/files

Go to bin directory of TestCntlrStub and modify the nbAppCfg.txt
ENB_IP_ADDR 172.168.10.134
MME_ADDR 172.168.10.135 // MME IP address on which MME is listening for SCTP connection from eNB
SCTP_IP_ADDR 172.168.10.134
UE_ETH_INTF enp0s9 //Interface should exist in the system
VS_IP_ADDR 172.168.1.200 //Not explored much on data path
sudo ./testCntrlr -f testCaseList_1.txt // Assumed EPC is already up and running

Hi @vimal2828 ,
can you share OS you are using, lksctp lib version ?
I am still getting situation described by @cgiraldo ?
INIT, INIT-ACK, and ABORT. Everything is terminating on SCTP level.

northmirko · 2020-09-29T08:55:08Z

Hi @vimal2828 ,
can you share you logs from /tmp/fw/

Mine are stuck here.

I finally made it, using of network namespaces (netns) was bad idea. Choice of two virtual machines made things finally work.

nickvsnetworking · 2020-10-04T05:01:38Z

Thanks a heap @vimal2828 - I've just submitted a PR with updates to the Readme doc to show the info you've shared for all!

hello what epc did you use?

Hello all i am getting below error while integrate the S1AP with Magma AGW. Our Network Conf is S1AP tester installed on Host machine and our AGW also installed on same host machine but with in Vagrant VM.

@jcjanask I switched to SRSRAN, much easier to extend code for custom purposes.
