Thanks for your reply Michael,

I tried ping by typing
ping <IP address of other machine>
while other machine had server_tool running and I got no reply.

I'm using 2 seperate machines (My desktop and laptop) which are connected to a router. I'm running Linux Fedora Core 3 on one machine and Linux Fedora Core 4 on the other. I'm running them as a virtual machine (using VMWare). I'm using bridged networking so that the linux OS has its own IP address.

I can connect to the internet normally and I'm not behind a firewall.

Here is my ip addr output:

-------------------
1st Machine
-------------------

[root@localhost programs]# ip addr
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue

3: sit0: <NOARP> mtu 1480 qdisc noop

Note that I use 192.168.0.102 (machine 1) and 192.168.40.128 (machine 2) as my IP address

Hope you can help out
Thanks :)

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?
