Bogdan,

Yes, this patch does work. The full URI is now being processed. Thanks!

Thanks,

Oh...you mentioned in the first email that you are looking to migrate the "duplicate_uri" from 1.11 to something 2.3 specific. This is why I pointed out the SIP based tracing.

Now, checking the hep_id parser, I guess it does not expect the '-' char in the URI part - could you check out this patch https://github.com/OpenSIPS/opensips/commit/ba2840639777d797889e4a3a74c0b56f02ce9aba<https://github.com/OpenSIPS/opensips/commit/ba2840639777d797889e4a3a74c0b56f02ce9aba> please? if this fix the problem, I can do a backport.

Bogdan,

Yes, that is what I have done, as I detailed originally. I am configuring the hep_id in the proto_hep module like this:

modparam("proto_hep", "hep_id", "[hid]homer-hep.test.com:5656;transport=udp;version=2")

But the module is not using the full URI I provided. I get the following errors:

Mar 26 19:59:58 [332] CRITICAL:core:mk_proxy: could not resolve hostname: "homer"
Mar 26 19:59:58 [332] ERROR:proto_hep:send_hep_message: bad hep host name!
Mar 26 19:59:58 [332] ERROR:siptrace:send_trace_proto_duplicate: failed to forward message to destination!
Mar 26 19:59:58 [332] ERROR:siptrace:save_siptrace: Failed to duplicate with hep to <homer:5656>

It seems to be discarding everything in the URI after the dash.

Thanks,
Ben Newlin

Hi Ben,

So, from siptrace module, you have multiple options in terms of what to do with the traced data:
    * you can duplicate it via SIP
    * you can dump it into DB
    * you can pack it over HEP for Homer
This is controlled via trace_id parameter in siptrace module.

Now, next step: if you decided for HEP, you need the proto_hep module where you have to define the Homer servers where the HEP data is to be sent - see the "hep_id" parameter.

Bogdan,

That is very good to know. I thought the siptrace module was using HEP.

But still, if I want to switch to HEP in the future, which I do, I need to be able to properly use a domain name in the proto_hep config. Any idea why that is not working as I described originally?

Thanks,
Ben Newlin

OK, it was a quick one :D...

The "duplicate_uri" from 1.11 was duplicating the traffic via SIP, not via HEP, so if you want to translate this setting, it has nothing to do with the proto_hep module, but still with the siptrace module like:

    /*sip trace id*/
    modparam("siptrace", "trace_id", "[tid]uri=sip:homer-hep.test.com:5656")

and use "tid" as tracing ID in the sip_trace function.

Has anyone had a chance to look into this DNS issue?

Hi,

While upgrading from 1.11 to 2.3, we have run into an issue with the parsing of the hep_id parameter in the proto_hep module.

In 1.11, we used the duplicate_uri setting in the siptrace module like so:

modparam("siptrace", "duplicate_uri", "sip:homer-hep.test.com:5656"<sip:homer-hep.test.com:5656>)

In 2.3, we converted this into the appropriate module config for proto_hep:

modparam("proto_hep", "hep_id", "[hid]homer-hep.test.com:5656;transport=udp;version=2")

However, this results in OpenSIPS complaining about receiving the wrong address:

Mar 26 19:59:58 [332] CRITICAL:core:mk_proxy: could not resolve hostname: "homer"
Mar 26 19:59:58 [332] ERROR:proto_hep:send_hep_message: bad hep host name!
Mar 26 19:59:58 [332] ERROR:siptrace:send_trace_proto_duplicate: failed to forward message to destination!
Mar 26 19:59:58 [332] ERROR:siptrace:save_siptrace: Failed to duplicate with hep to <homer:5656>

It appears the proto_hep module parameter parsing doesn’t allow for dashes/hyphens in the address portion, so it ends up with only a small part of the actual hostname of our Homer server.

Thanks,
Ben Newlin
