Hello
I have read about more articles , OMA Specs and few faqs on the kannel
mailing list archive also. But i have remained few probs with me, Can
some body help me , on develop/configure kannel for WAP 2.0 ?
Hi William,
Kannel can be used as WAP 1.2.1 gateway as of this time. In combination with a
HTTP proxy (i.e. squid or apache2) also as WAP 2.0 gateway in some extends.
In fact I provide a re-written Kannel WAP stack as commercial package, the
Kannel CG (carrier-grade) WAP 1.2.1/2.0 gateway for various CDMA and GSM wirless
network operators around the world, including full RADIUS accounting field value
proxying. In addition Kannel-CG includes a custom HTTP proxy that integrates
fully to the model.
1. When we taking Radius Accounting to kannel box , we shouldn't have a
radius client in between GGSN/SGGSN and the Kannel Box ? or is it must
to be there for handling radius accounts ???
Now, wapbox will run an own RADIUS acct proxy thread. Meaning, we expect PDUs
from the NAS (GGSN) and forward those to the final RADIUS server.
In the Kannel-CG version, we have an own daemon for that, which is able to proxy
to 1-to-N destination transparently, with a flexible storage subsystem for the
RADIUS information retrievement.
2. If we are using SQUID as a web proxy , and we need to get exact
clients ip , which assigned by the GGSN , how can we filtered out it
form the kannel box ? Generally web proxy server receiving wap box's
IP not the clients IP.
Now, squid can be configured to pass the client IP in a specific HTTP header to
the final HTTP server destination. So you get the origination source IP
reference, instead of relying only to the squid server IP on the HTTP server
side of the request.
3. What is the best design for kannel WAP 2.0 architecture ???
Squid is a good approach. We use it in Kannel-CG, but with modifications to the
internal code to fit seamlessly to the architecture.
4. When receiving Accounting form the GGSN to the kannel box , how can
we filtered out all the UDP requests and HTTP requests ???
Can you point out what you want to filter here?
Regards,
Stipe
