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,
-Ray

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.
BR,

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
