logicaCMG SMPP Simulator Connection

Hi.
Everything is smooth and successfully configured; received/sent reply
to/from servlet using fakesmsc.
Now I am testing SMPP connection with logicaCMG Simulator;

Its also connected to bearerb0x successfully; with following settings in
kannel.conf

# SMSC SMPP
group = smsc
smsc = smpp
host = 127.0.0.1
port =1010
receive-port =1010
smsc-username =pavel
smsc-password =xxxx
system-type ="VMA"
address-range = ""

once started, simulator gives me options
1- start simulator
2- stop simulator
3- show clients
4- send message
..
.
.
Now, after successfully starting at port 1010; when i check (3)
its show 2 users (whereas I connected only throu one session and one user
'pavel' and it was connected in first attemp
Q1- Why does it show the same username as two sessions?

When I try (4) [send message]; it prompts
pavel
pavel
Please enter connection Name (or watever): pavel (i entered)
Please enter message : my message goes here
Message Sent!

But Bearer Box displays message in its logs- Destination cant be null; MO
discarded
Q2: Why? How can I make it run?

Thanks for your help in anticipation
