Hi,

please note that you have to run

./configure
make clean all

after you have run

insmod ipv6

Then the sctplib is compiled with IPv6 support.

It looks like you are using sctplib binaries which
have not the IPv6 support compiled in.

Best regards
Michael

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:

sctp_registerInstance: an error occured.
[root@dhcppc2 programs]# ./terminal -i -V -s ::1 -d

[root@dhcppc2 programs]# ./echo_server -i -V -s

[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,
