I found that all SCTP scans were silently discarded on receiver side when running nmap on 64-bit architecture. The discards were due to incorrect checksum on SCTP level and might result in a false negative. Patch is attached.
Thank you, this is a great find. I have committed you patch, and verified that an SCTP without the patch fails and one with the patch succeeds. # nmap -sY scanme.roe.ch PORT STATE SERVICE 7/sctp open echo 9/sctp open discard 80/sctp open http David Fifield _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
