hi,

thanks for your mail. i tried the way that you said.
at first i run ./echo_server on pc1.
and after that i run ./terminal -d 172.30.58.2 on pc2
and i input some characters (as for example- vcvvbbbb)
and i got the following error:

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

i am looking forward to hearing from you.

regards,
babu
