Hello,

i have just started looking at the sctp. i would like
to test multihoming feature of sctp. i read some
discussion Archives from the website sctp.de. and i
tried to run the example client and sever program. 1st
i run sever program on one host using the following
command:
[root@localhost programs]# ./echo_server -i&

and after that, in another host i run the client
program using the following command:
[root@localhost programs]# ./terminal -d 127.0.0.1 -i

and after input some characters, i press enter and i
got the following errors:

sctp_send: internal error !
sctp_receiveUnsent: Association is not in state
CLOSED.
SCTP_receiveUnacked: Association is not in state
CLOSED.
sctp_deleteAssociation: assoc not ready for deletion
or lib not initialized:

i'm using fedora core 2 operating system. and my
network configuration is as follows:

the network configuration of one host in which i run
server program:
[root@localhost root]# ifconfig
eth0 Link encap:Ethernet HWaddr

the network configuration of another host in which i
