Dear SCTP mommunity,
I found a trouble when trying to run echo_server with
IPv6.

My SCTP combination is: Redhat 9 kernel 2.4.20-31.9 ,
sctplib-1.0.1, socketapi-1.3.1.

I can run SCTP with IPv4 (thanks Andreas for your
helping :) )
[root@dhcppc2 programs]# ./echo_server -i -V -s
127.0.0.1
1 : Communication up (10 In-Streams, 10
Out-Streams)
1 : Network status change: path 0 is now
CONFIRMED
1 : Data arrived (11 bytes on stream 0, ordered)

[root@dhcppc2 programs]# ./terminal -i -V -s 127.0.0.1
-d 127.0.0.1
1 : Communication up (1 paths, 10 In-Streams, 10
Out-Streams)
1 : Network status change: path 0 is now
CONFIRMED
Hello SCTP
1 : Data arrived (11 bytes on stream 0, ordered)
Hello SCTP

However, I'm unable to run echo_server with IPv6
although my IPv6 is enable.

When I tried to run echo_server and terminal, they
said:
[root@dhcppc2 programs]# ./echo_server -i -V -s ::1
sctp_registerInstance: an error occured.
[root@dhcppc2 programs]# ./terminal -i -V -s ::1 -d
::1
sctp_registerInstance: an error occured.

[root@dhcppc2 programs]# ./echo_server -i -V -s
fe80::206:1bff:fed2:cbe5
sctp_registerInstance: an error occured.
[root@dhcppc2 programs]# ./terminal -i -V -s
fe80::206:1bff:fed2:cbe5 -d fe80::206:1bff:fed2:cbe5
sctp_registerInstance: an error occured.

Anyone can help me?
Thank you very much.

Sincerely yours,
Vinh Dat
