upper registration route problem - authentication fails

Hi all,


I have been searching the forum for hours now but can not find any hint what I' m doing wrong. I' m running OpenSBC in B2B upper registration mode and would like to have my clients registering whith our existing softswitch. I have set up everything according to the tutorials and howto's which can be found in this forum.

The client sends a register message to the SBC, the SBC acknowledges that there is an upper registration route and forwards the request to the softswitch. The softswitch reguires digest authentication and sends a 401 unauthorized back. I would expect now that this message is relayed back to the original client in order to continue with the authentication.


For some reason, that message never arrives at the client - therefore the client is trying and trying to authenticate.


Here is what I' m seeing in the log file:

Has somebody seen such a behavior ? Is my expectation right that the SBC should forward the request and not close the proxy session immediately ?

Many thanks in advance.

Re: upper registration route problem - authentication fails
Hi,

I am unable to replicate this in my box. However, I have a hunch what is causing this for you. You need to help me out understand why it is happening. Can you trace though ProxySession.cxx for me and find the following code block:

void ProxySession::OnFinalResponse( SIPMessage & message )
{
GCVERIFYREF_VOID( "ProxySession::OnFinalResponse" );

SIPMessage response = message;

Via via;
response.GetViaAt( 0, via );

if( GetTransportManager()->IsLocalAddressAndPort( via.GetURI() ) )
response.PopTopVia();

If my hunch is correct, OpenSBC is unable to POP the top-most via of the response because it did not resolve as a local address:port. Can you confirm this? Please add a PTRACE within the if block like so:

if( GetTransportManager()->IsLocalAddressAndPort( via.GetURI() ) )
{
PTRACE( 1, "FATAL!!!! Unable to POP Top-most Via" );
response.PopTopVia();
}

Let me know if it appears in your tests. If you are a developer, it would be nice if you could trace into IsLocalAddressAndPort function and tell me where it fails.

Hi all,


I have been searching the forum for hours now but can not find any hint what I' m doing wrong. I' m running OpenSBC in B2B upper registration mode and would like to have my clients registering whith our existing softswitch. I have set up everything according to the tutorials and howto's which can be found in this forum.

The client sends a register message to the SBC, the SBC acknowledges that there is an upper registration route and forwards the request to the softswitch. The softswitch reguires digest authentication and sends a 401 unauthorized back. I would expect now that this message is relayed back to the original client in order to continue with the authentication.


For some reason, that message never arrives at the client - therefore the client is trying and trying to authenticate.


Here is what I' m seeing in the log file:

Has somebody seen such a behavior ? Is my expectation right that the SBC should forward the request and not close the proxy session immediately ?

Many thanks in advance.

Re: upper registration route problem - authentication fails
oops! sorryy it should be

if( GetTransportManager()->IsLocalAddressAndPort( via.GetURI() ) )
{
response.PopTopVia();
}else
{
PTRACE( 1, "FATAL!!!! Unable to POP Top-most Via" );
}

Re: upper registration route problem - authentication fails
Hello Joegen,

many thanks for your reply and pointing me into the right direction. You have been perfectly right with your hunch - the problem is that the OpenSBC cannot pop the first via header. I have digged a bit deeper into the source code and added some traces to the functions where I suspect the error.

From my point of view it goes the following way :

1. ProxySession.cxx --> GetTransportManager()->IsLocalAddressAndPort( via.GetURI() ) is called
since this call fails, response.PopTopVia() is not executed and the message is not routed back to the client

2. Within SIPTransportManager::IsLocalAddressAndPort the function SIPTransport::Resolve( uri, addr, port ) is called
- the call for this function fails and FALSE is returned

3. SIPTransport::Resolve is called. I' m still trying to find out at which point it fails in this function. I will provide an update as soon as I know.

Regards,

Andre

Re: upper registration route problem - authentication fails
Hi,

Thanks for confirming. Since I can't replicate this locally, it seems this problem is specific to your box. It will be of great value if we can pinpoint where exactly it fails in SIPTransport::Resolve() so we can give the library a defense mechanism to prevent this behavior. To give you a clue where to look next. A lot of the stuffs in resolving uris happen in

[http://SIPSrvRecord.cxx|http://SIPSrvRecord.cxx]

BOOL SIPSrvRecord::Resolve(
const OString & _domain,
const OString & _proto,
WORD port
);

So if it SIPTransport::Resolve fails somewhere, this is likely the place where it will happen.

Re: upper registration route problem - authentication fails

Hello Joegen,

I'm close to give up on that... I have been debugging a lot of things so far - but there is no true result. The only thing I have found is the following:


The via.GetUri() is called I see a strange behavior when we are parsing the via: headers. I added some debugs in order to find out what it causes:

337287:45:59.687 PWL: [CID=0x0000] show uri in via.GetURI Part 1:
337287:45:59.687 PWL: [CID=0x0000] show uri in via.GetURI Part 2, after GetAddress() sip: 85.xx.x.200
337287:45:59.687 PWL: [CID=0x0000] show uri in via.GetURI: sip: 85.xx.x.200:5060


As you can see, we have a space between sip: and the IP Address. What is your opinion ? Can that be the root cause ? I tried to find out where the sip: is added but were unable to. Can you please give me a hint ? Does it make sense to send you a complete SIP trace off list ? Many thanks for your help in advance.

Regards,

Andre

Re: upper registration route problem - authentication fails
Don't give up just yet. I think your server is re-encoding the Via in the response and adding an extra space after SIP/2.0/UDP. I have applied a patch that would handle this behavior. Try the latet from CVS and let me know how it goes.

Re: upper registration route problem - authentication fails

Hello Joegen,

it works now, many thanks. A little Trim() makes sometimes a big difference... I need to spend a little bit more time reading the source code to get a better understanding.

Many thanks again for the great help.

Regards,

Andre
