Hello @josa,

To me, the way to check if OpenVPN connection is successfully established,

programmatically, would be outside of RFA, via OS/shell.

By searching on this topic I can see developers recommending multiple approaches, none very simple.

The way I would prefer, personally, would be this one, via netstat and examining the output.

Another approach is openvpn --show-net

If you are coding in RFA.NET, C#, then this way seems pretty reasonable.

Hope this helps,

Hi @josa,

The ADS endpoint in TREP typically listens on TCP port 14002 for RSSL connections. You can try a telnet to that port to verify that it is connectable.

Thanks Gurpreet. I would like to be able to do this programmatically via TREP API and not via telnet. OpenDACS has something similar that I would like to use. Can you help please?

Regards,

josa

You can use a barebone Elektron Message API example to check if the sample can connect and login to TREP. Get the EMA package for Java or C++ here.

Start with 100__MarketPrice__Streaming in the Examples directory.

Thanks. Am using RFA and not Elektron. Do you have for RFA please?

RFA has similar examples - look at StarterConsumer in Examples directory.

Hi @Gurpreet, I can't find this in RFA. Could help point me to which section of codes in the StarterConsumer that does this?

To test TREP with RFA, you can run the StaterConsumer (RFA C++, RFA .NET) or QuickStartConsumer (RFA Java) example in the RFA package. Otherwise, you can use a tool from our partner as mentioned in this question.

To test DACS Sink Daemon with OpenDACS API, you can run the dacsSubscribeClient example in OpenDACS API package or follow OpenDACS tutorials.

Thanks @ jirapongse.phuriphanvichai. This does not answer my question. What I am interesting in programmatically is this. Am connecting to TREP test account via OpenVPN. If I have not initiated the OpenVPN connection and I run this StartConsumer examples, the application get stucked and I wont know what is going on.

It appears you guys don't have something out of box I can use via the API, I have created a workaround, so please close this ticket.

Thanks,

@josa

None of the answers resolved my questions.
