Hi Michael,

I didn't know that running multiple sctplib instances is not
recommended. But, how can one run multiple applications on
one machine by using sctplib.

The recommended way is not running multiple applications on one
machine. But the socketAPI does try to work around that which
does not always work. You are talking about the listening
sockets, I think. You can control the client port by using
the bind() system call on the client side.

Can you send a ethereal trace file for a situation which does
not work? Send it to me, not to the list.

Best regards
Michael

I'm not sure if I understood your question well about
controlling the port numbers. Each of the 3 applications has
its own port number different from the other 2, e.g., in our
case those are 5060, 5061 and 5062. Could you explain me in
short what you mean by controlling the port numbers oneself?

Best regards,
Marjan

Hi Majan,

having multiple instances of the sctplib is not the
recommended way. You should only have one.

If you are running multiple versions of it YOU must
control the port numbers by yourself. How are you handling
them?

Hi,

We have a problem with handling SCTP sockets in our

application using

rsplib/socketapi/sctplib. Here is the problem description.

I have three instances of the SIP application that have to

run

simultaneously on the same machine. Each of them creates

sockets to

either with another SIP application on the same machine or

with an

application on another machine. During run time, there is

on average 3

sockets created at each SIP application, so on average 9

sockets in

one machine.

I run the 3 instances simulteneously. Sometimes the

communication is

as expected, but sometimes certain sockets cannot be read

and SIP

messages are not received at all.

Could it be that multiple sockets being opened by several

application

in one machine maye conflict with each other?

The same problem appears with both socketapi-1.2.0 and

socketapi-1.0.0.

Best regards,
Marjan
