Hello Michael and all,

Thanks for your advice regarding using Linux. I managed to install and compile sctplib according to your instructions without trouble. But when I try running programs I always get errors. Can you please have a look at the errors and give me an idea as to what might be wrong?

I’m using Fedora Core 3 on one machine and 4 on the other.

Here are 3 scenarios
---------------------------------------
Scenario 1
---------------
[root@localhost programs]# ./echo_server -i & ./terminal -d 127.0.0.1 -i

hi
hi
hello
hello

Nothing is wrong. These Errors are false. Just set Current_error_log_ to 0 in
globals.h and recompile.

---------------------------------------
Scenario 2
---------------
At the server:
[root@localhost programs]# ./echo_tool -V

At the client:
[root@localhost programs]# ./echo_tool -V -n 1 -d 192.168.40.128

nothing happens at both sides



Are the server and client running on the same machine? It seems that
the client can not reach the server. Is it possible via ping?
---------------------------------------
Scenario 3
---------------
At the server:
[root@localhost programs]# ./echo_server

At the client:
[root@localhost programs]# ./terminal -V -d 192.168.40.128
hello
Error Info: 22:07:27.706 - se_ulpsend: StreamEngine Instance doesn't
exist....Returning !
sctp_send: internal error !
The association has not been established. It is the same problem as
above. Is there a firewall running at the client and/or server?
