hi,

i can answer the both questions with yes and the
following is working fine on one machine:

./echo_server -i &
./terminal -d 127.0.0.1 -i

but the following is giving me the error:
./echo_server on pc1.
./terminal -d 172.30.58.2 on pc2

[root@localhost programs]# ./terminal -d 172.30.58.2
> vcvvbbbb
> sctp_send: internal error !

regards,
babu
