[OpenSIPS-Users] feasablity / interest in a feature request.

[Ben Newlin]

Johan,

Unfortunately, the server on which I am tracing is only transaction-aware and does not have Dialog, so I cannot verify this.

I will say that we call trace() very early in message processing, almost first thing, and we do still see all changes on the outbound message.

I use this for invite based dialogs.

trace("hep_id","d","sip");

I call it just before topology_hiding()

I don't see from/to header changes.

Can you check on your side Ben ?

We are using siptrace and we get both the incoming and outbound message captured, with all changes. I think it depends on the scope you provide [1]. We use scope T for transactions and we get both.

Although, we are using OpenSIPS 2.4. It’s possible the functionality has changed in 3.x. In which case, I would agree that it is not good.

How about running a continuous tshark/pcap/ngrep on interfaces of interest.
you can run every 10min.  putting in 10min files.

It depends on purpose. For example, I need an initial (untouched) packet there.

Hi,


when you use the siptrace module and you go to homer from opensips
(hence without a port mirror/span port on a switch), when you change
from /to header, then the homer trace doesnot reflect the real packet
that exits opensips (as we all know, from to header changes are only
active when the packet is send out).


I find this annoying as the purpose of having a tracer is defeated by
this : we want to see the real packets with the changes applied.


Therefore : are there more people on the list who are ennoyed by this ?
If yes, then I will open a feature request for it.


wkr,
