Abort chunk in SCTP

0 votes

I am using LKSCTP in my project, one sometime I see that by box receives About chunk from the peer. Now question is what are the possibilities for which we can receive abort chunk from remote.

Many reason, more than would be efficient to name in a single email. The abort chunk however should have a string encoded into it giving some explination for the abort. User space apps IIRC can read that string (or you can look at it in a tcpdump if you need to). That will give you some clues regarding the root cause.

I would like to ask about the IP address on dource IP address of SCTP INIT chunk and the IPv4 address parameter inside SCTP INIT chunk.

If the source IP of the SCTP INIT chunk is 10.1.1.84, but the IP address INSIDE the INIT chunk, i.e. the IPv4 address parameter, is using a different IP address, says 192.1.1.84, what will be happened?

I did a testing on a SCTP server and client environment, and it seems the SCTP server tried to send INIT_ACK back to the source IP to the client, i.e. the destination IP address is 10.1.1.84. but somehow, the SCTP server generate two HEARTBEAT request, one to 10.1.1.84 and one to 192.1.1.84.

Is it a problem on our SCTP server application? any idea on this?

It is found that IP X haven't replied heartbeat Ack to IP A but our client will not try another path B->Y. Would you advise how B->Y path can be enable?

lksctp client IP info:
Primary IP: A
Secondary IP: B

Server primary IP: X
Server secondary IP: Y
