hi



We are using the sctplib for our Sigtran implementation. OS is RedHat 9.0 (kernel 2.4.20-8, unpatched), sctplib version is 1.0.1

1.0.4 is available and has ... let's say less bugs than 1.0.4.

Occasionally, when we do a fresh install of Redhat and then install the sctp library, our app does not get the SCTP_COMM_UP event when the client sctp socket is connected.

An ethereal trace shows the sctp socket being connected, and heartbeats being sent, but the application never gets any further, because of the missing event.

e.g. INIT, INIT ACK, COOKIE ECHO, COOKIE ACK, HEARTBEAT, HEARTBEAT ACK … etc.



The only way to fix this (which doesn't always work) is to reinstall the OS and the libraries until it does.

Interesting...I have no idea.

Once it is working, the problem never reoccurs.



Any ideas much appreciated …! Is the SCTP_COMM_UP always received when a connection is established?

That is the idea. Anything else is a bug.

regards,
