Hi Sasko,
Set loglevel to 0, so kannel.log contains as much information as possible. Sometimes, a malformed PDU can bring your connection down. With the information gathered, phone the SMSC operator to pinpoint the problem. Be sure to set same SMPP version.
Regards.

Subject: Re: connection problem
Thank you Rodrigo for your prompt reply... The problem remains with the 1.4.0 version as well. The thing is that it all works fine and then just blocks the transmitter channel. I have separate receiver and transmiter on the same smsc connection. Kannel conects as a receiver and as a transmiter on the same port. The receiver (Kannel receives and SMSC sends - that is transmitter on the SMSC and receiver4 on Kannel) work fine and the other direction blocks. So I assume that the TCP is fine... Kannel enters a reconection loop for that channel while keeps receiveing messages and calls the appropriate services for them. The problem is that it can not send reply messages to teh SMSC... Please let me know if you have any othwer ideas for solving the problem...
Kindest Regards, Sasko Celakvoski

As a first advise, I would sugest you to try Kannel 1.4.0. Second, try to telnet the server manually. If you get a prompt, then the TCP connection is fine.
>telnet 172.20.3.105 3704
If you dont, check your routes, firewall rules, etc. which may be preventing the connection.
Best Regards, Rodrigo.
