Hi Nikos,
(Sorry in advance, as this is becoming a long message.)
Regarding the port 49202 thing, I was expecting port 9201 for WAP (like
you indicate), but wireshark was saying that everything was happening on
49202 for some reason.. Maybe it was confused... Anyway, I've made some
progress and don't really care about that issue any more... So...
A couple other things:
1. (as a side note) I've discovered that kannel is very sensitive, if
you do stop or start-smsc admin request to kannel via
"http://localhost:13000/stop-smsc?smsc=blah"; and blah isn't defined in
kannel as an smsc, bearerbox will most definitely crash and burn.
2. I'm only using kannel to handle incoming/outgoing SMS. I need to
send MMS via my operators mmsc, so I'm not dealing with notification or
wapbox in kannel or wap requests to mbuni. (Let me know if I'm not on
the right track here.) So SMS goes through kannel, and I'm hitting
mbuni with an HTTP request to get it to send out an MMS.
I am so close I can almost taste it... (I discovered that something is
wrong with one of my GSM modems or accounts, but I've got one that
almost works..)
Here's where I'm at:
(Kannel and Mbuni are running, of course)
1. I inject an MMS into Mbuni via a URL that looks like this:
http://testserver:8193/?username=user&password=pass&from=100&to=16125555555&subject=SomeSubject&mmsc=modem&content-url=http://testserver/img/mms/offer_10.jpg
2. Mbuni hits my webserver, downloads the offer_10.jpg image. (works
great) Log entries on mbuni look like this:

3. Mbuni shuts the kannel connection down. (works great)
4. PPP starts up. (works great)
5. Mbuni POSTs the MMS to the operator's mmsc. Request header looks
like this:
POST http://mmsc.cingular.com HTTP/1.1

Via: 1.1 alpmag2r1fe04WAP2-mbl:8080
...00001......Message accepted..123005015110000300003.
(Everything looks really good.. other MMSC accepted my message!).
However, the message is never delivered to my handset. If I change the
URL that I'm using to inject the msg into mbuni and add
'&text=SomeTextHere', then I actually get the message. I would appear
that mbuni is not formatting the mms properly when I'm trying to send an
image or something.
I am evaluating a couple commercial MMS-sending apps, and found that
they can send out an MMS that looks very similar (in wireshark anyway),
and I do receive the MMS (so I know that the modem is good, the plan
supports MMS, etc).
Any ideas?
Thanks for your help!

Hi,
I have lots of experience with kannel and the at driver. Normally
bearerbox panics when the modem goes down. It is always nice to learn
about new tricks ;-)
What you are reading is not WAP. Wap 1.x works over udp ports 9200 -
9203, not 49202. Kannel's bearerbox listens in at these ports for wap
traffic. Post packet dump to verify it.
Mbuni works with kannel both for notification (smsbox) and wap traffic
for older mobiles. Kannel's wapbox is configured with map-url to
redirect wap requests to mbuni. Read mbuni configuration.
Also please post POST request you are sending along with detailed logs
of attempt.
BR,
Nikos

Subject: Re: [Users] mm1 using wrong interface to send
So, it looks like I'm having problems sending out to
wireless.cingular.com. I tried to POST the content of the data file
directly using curl, and I pretty much get the same thing that I get
when mbuni tries. (It does a POST of the data and just sits there.)
I've looked at a commercial app that works (on Windows), and when I
do a packet trace, I see that it's sending everything UDP and the
content looks to be SMIL. So I'm thinking that it's using the WAP1
gateway and sending SMIL formatted data instead. (Although the udp
port (49202) and host IP) are not what I thought I would find, so
maybe I don't understand WAP as well as I thought I did.)
Any ideas? Can I configure mbuni to send via a wap1 gateway? Am I
even looking in the right direction?
Thanks,

Hi Nikos,
The libmmsbox_mm1 library does a great job of telling kannel to take
the modem offline so that the dialup PPP session can start (and that
works well). The problem that I'm seeing seems to be related more
with libcurl binding to the wrong interface. I was able to add a
configuration setting to specify the libcurl interface (ppp0) and
recompile. This, with a couple sleeps, causes it to bind to ppp0.
(I'm getting further, but it still isn't working correctly; I'll
post my next issue soon :)
Thanks,

Hi,
Do you need to shutdown kannel? Can mbuni notification work without
kannel? You know that kannel supports HTTP smsc and therefore you
can connect through it.

Subject: [Users] mm1 using wrong interface to send
Hi,
I'm very close to getting mbuni to send out vi MM1 on a GSM modem.
Mbuni will tell kannel to shut down (which it does), and it brings
up the ppp connection.
However, it never seems to connect to AT&T's SMSC. So I did a
tcpdump on the ppp0 interface, and I can see mbuni trying to send
packets on port 80 to the AT&T proxy (wireless.cingular.com), but
the source address is my Ethernet IP instead of what's assigned to
ppp0:
tcpdump -i ppp0 -n
tcpdump: verbose output suppressed, use -v or -vv for full
protocol decode
listening on ppp0, link-type LINUX_SLL (Linux cooked), capture
size 96 bytes
23:26:12.984086 IP 172.18.3.15.45500 > 66.209.11.32.80: Flags [S],
seq 3553051624, win 5840, options [mss 1460,sackOK,TS val
151026241 ecr 0,nop,wscale 5], length 0
I've got a static route in place and I can do 'telnet
wireless.cingular.com 80' and it connects to the proxy fine.
Any ideas? I'm looking at changing the libcurl stuff in
mmsbox-mm1, but I thought I'd check to see if there was an easier
way.
Here's my custom-settings:
group = mmsc
id = modem
type = custom
custom-settings = "smsc-on=lynx -dump
'http://localhost:13000/start-smsc?password=pass&smsc=modem';smsc-off=lynx
-dump
'http://localhost:13000/stop-smsc?password=pass&smsc=modem';gprs-on=/root/startppp.sh;gprs-pid=cat
/root/ppp-wrapper.pid|head
-1;port=13014;mmsc-url=http://mmsc.cingular.com;proxy=wireless.cingular.com:80;msisdn=6128891111";
mmsc-library = /usr/local/lib/libmmsbox_mm1.so
Thanks in advance,
-Ray
