Hello all,

I have got one TX and one RX configured with following details:


#RX Group
group = smsc
smsc = smpp
smsc-username = xxx
smsc-password = xxxx
system-type = xxx
host = xxx.xxx.xxx.xxx
port = 0
receive-port = 1111

#TX Group
group = smsc
smsc = smpp
smsc-username = xxx
smsc-password = xxxx
system-type = xxx
host = xxx.xxx.xxx.xxx
port = 1111
receive-port = 0
Also i get the message that Client is connected in Kannel.log file.
But after sometime am getting following error in the log files:

2006-07-18 20:56:33 [6] ERROR: Unknown SMPP_PDU type, internal error.
2006-07-18 20:47:24 [6] ERROR: SMPP[SMPP:xxx.xxx.xxx.xxx:1111/1111:xxx:xxx]:
PDU unpacking failed.
2006-07-18 20:47:24 [6] ERROR: SMPP[SMPP:xxx.xxx.xxx.xxx:1111/1111:xxx:xxx]:
I/O error or other error. Re-connecting.


Please suggest as i am not able to understand where the problem is....

now, this means that Kannel couldn't decode the PDU packet it received from the SMPP SMSC.

Are you running the log in debug log level in order to provide more data on this? If this doesn't help, you may use tcpdump to capture the IP packets and analyze the SMPP flow with ethereal. It will show you if there is something wrong with the packets itself, which looks so.
