In the kannel source code, there is a file "gw/smsc_smpp.c". At the start of this file there's "dump_pdu" function, which is enabled by changing "#if 1" to "#if 0". Rebuild your kannel and you'll have a dump of all PDUs in the "bearrer.log". > Going to your problem, I have a similar behaviour with Logica SMSC and the > problem was solved when the idle timeout of the SMSC was increased.

I have successfully connected to the same SMSC as a "bind_receiver" with a perl program, and it works very well. It's strage that the "transmit" part of kannel works ok. -- Damjan Georgievski | Дамјан Георгиевски Skopje, Macedonia | Скопје, Македонија
