I am just a poor Java coder, not a Kannel expert, so don't trust my comments too much. But, your data gave me some ideas. > 2002-05-31 01:29:40 [8] DEBUG: data: 47 45 54 20 2f 74 65 73 > GET /tes > 2002-05-31 01:29:40 [8] DEBUG: data: 74 2e 61 73 70 3f 6d 65 > t.asp?me > 2002-05-31 01:29:40 [8] DEBUG: data: 73 73 61 67 65 3d 20 48 > ssage= H > Ok, this shows that there is no payload when smsbox makes a request to your application.

It should reveal whether Vodafone's gateway is sending you data or not - and is it sending it in proper format and field. This sounds like some version incompability problem. What version of SMPP does Vodafone use? The version supported by Kannel is SMPP 3.4, thought I have no idea of how downwards compatible SMPP is... And specs are never clear enough, it might as well be that Kannel and Vodafone interpret spec different way. Kannel SMPP driver is known to work and to my knowledge in use here and there, so it's most propably not badly broken. If you don't know how to look at network traffic, there is at least two ways: There is a precompiler option at the beginning of the file gw/smsc_smpp.c that controls whether SMPP driver dumps all protocol packet to log or not. Change the #if 1 to #if 0 and recompule. Other way to is to just sniff the network traffic. I have used mainyl ngrep for this job. Just tell it to print out everything based on IP address of the SMPP SMSC. So, no any quick and clean suggestions, sorry. -- Jari Juslin, Development Team Leader, MatchEm Ltd
