Re: [Freeswitch-users] Q931 decoding Update
Hello, if you have more than one call in your q931.pcap file captured, you may like to seperate the call flows in wireshark's packet list. wireshark allows you to sort the packets by e.g. q931 call reference first. All you have to do is this: Open q931 pcap file in wireshark, goto edit->preferences...->Columns Enter a title of your new column e.g "Q931 Call Ref" in title-field. Select "Custom" from Format-field. Enter exactly "q931.call_ref" without quotes into the field next to Format-field. Then apply it and close the window. Now you have a "Q931 Call Ref" column in the packet list. Click on it and the Flows a sorted first by "q931 call reference" and second by time. regards Helmut ___ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org

We need to add more than this including detection in openzap configure.in if libpcap is available (headers and lib) and if not, disabling the functionality.

Re: [Freeswitch-users] Q931 decoding Update
Hello,
today I uploaded the Q931-To-Pcap patch into openzap's trunk (r628). So
you can test it.
How to start Q931 to pcap ?
In FS just enter "oz q931_pcap on [pcapfilename without
suffix]" to start logging q931 packets to pcap. It opens a file called
"q931.pcap" or ".pcap". It is saved in FS's log directory.
has currently not really an affect to the command. It is only
used to make sure that you have at least one valid span configured.
Further it is put into 802.1q vlan tag id which is displayed in
wireshrak and tshark. Unfortunately I couldn't test it yet (On my side
it's always zero).
How to stop Q931 pcap?
Simply enter "oz q931_pcap off" into FS console.
must be valid, but has no affect. Second way is to unload openzap module
or shutdown FS.
How are the packets saved?
All Q931 packets send or received by any span are saved into one file.
To see from where to where the packets was send, the FreeSWITCH's side
is always marked with ethernet address "02:00:01:AA:AA:AA" and IP
address "1.1.1.1"
Remote side is always marked with ethernet address "02:00:01:BB:BB:BB"
and IP adresss "2.2.2.2"
Span ID is intended to be put into VLAN ID, but this is currently not
sure. Maybe it's spanid-1 or always zero - I don't know.
The pcap timestamp starts with 0 and is increased by each q931 packet.
(Maybe a real timestamp is better here)
After each saved q931 packet data is flushed into pcap file. This is
needed for the small perl script below.
How to decode it with wireshark?
Get the pcap file from FS log dir and send it via email, ftp or scp to
where you have wireshark running. Open it in wireshark. Current
wireshark decode the stuff by default as "TPKT - Unknown TPDU type
(0x0)". Of course we have a TPKT packet, but wireshark is not able to
detect the Q931 packet by default. So just do a right click on such a
packet list entry, choose "decode as ..." and click on "do not decode".
You can also click on "Decode" and then choose AIM or CFLOW protocol.
Yes, AIM is not really Q931 or TPKT, but it works... After applying the
packets are decoded as wanted. The black color in the packet list marks
some little bugs in the TCP packet generated by this patch. E.g. tcp
checksum is zero, but should be vaild. I have code to calculate it, but
in my eyes it is an unescessary load for FS.
How to decode it with tshark?
tshark allows us to decode pcap files right on cli. To do so just enter
this:
tshark -d tcp.port==102,aim -Rq931 -Ttext -V -r
aim is the protocol as what tshark should decode the tcp payload. Some
other protocols are working to to get tcp's payload decoded as TPKT with
q931 (she so called "Q931 over IP").
Unfortunately it decodes not just q931 but the whole overhead
(ethernet,ip,tcp,tpkt) so I build a perl script, which extracts only
Q931 packets. For this script I have to flush each Q931 packet into the
pcap file, cause this allows to have some kind of real time decoding.
You have to start Q931ToPcap logging in FS first, then start the script.
You need to have tshark installed for this. The script has the pcap
filename incl. path as an optional argument. If not given, it uses the
default filename defined within the script. To stop the script press
"ctrl+c".
Here is the script:
#!/usr/bin/perl
$default_filename="/opt/app/voip/ippbx/log/q931.pcap";
$display=0;
if($#ARGV<0){
$filename=$default_filename;
}
else{
$filename=$ARGV[0];
}
$cmd="tail -n +0 -f ".$filename." | tshark -d tcp.port==102,aim -Rq931
-Ttext -V -i - 2>1|";
print "\n";
open(PCAP, $cmd);
while ($line=)
{
chomp($line);
if($line=~/^Frame ([0-9]+) \(/)
{
$number=$1;
}
if($line=~/Destination: 02:00:01:aa:aa:aa/i)

}
elsif(length($line)==0)

printf("-- $mode Packet number: %05i --- SpanID:

}
print "$line\n";

Hi Stefan,
I'm not sure what you want to tell me with the diff. Maybe I should hook
into the CallBack log function to get the span_id?
After your hint I looked into FS's concole log and found that even the
Q931 callback log function displays span_id 0
I think this line:
zap_log("Span", "Q.931", span->span_id, (int)level, "%s", msg);
produces this line:
2009-01-29 11:16:20 [DEBUG] Span:0 Q.931() Receiving message from Layer4
(size: 212, type: 69)
in FS console. There span_id is zero despite the fact that span_id in
openzap.conf.xml is "1"
openzap seems to set the span_id during zap_span_create(). The first
span gets the span_id 1.
Unfortuantely neither FS console nor my code displays the span id as
expected.
I would like to have it, because I want to put it into pcap file to give
a hint in wireshark from which span the traffic is.

Helmut

Looks good, you might want to consider making the file name that is generated be an optional argument but it's not necessary just a suggestion.

Re: [Freeswitch-users] Q931 decoding Update
Hello, to keep you informed. The stand alone c code is fully working now. wireshark can decode and display the generated packets containing Q931 hex dump samples I copied from FS log into the c code. So now I will start to put it into openzap/mod_openzap. regards helmut ___ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
