하나의 시스템에서 lksctp-tools-1.0.6-3.el5 (Red Hat Enterprise Linux 서버 릴리스 5.8 (Tikanga))를 사용하고 있고, 하나의 시스템에서 lksctp-tools-1.0.10 -7.el6.x86_64 (Red Hat Enterprise Linux 서버 릴리스 6.5 (산티아고))를 다른 시스템에 설치하십시오. JAVA 응용 프로그램을 통해 SCTP 연결을 설정하려고합니다. SCTP 서버 (172.16.150.14)가 시스템 (lksctp-tools-1.0.6-3.el5)에서 실행 중이었고 JAVA SCTP 클라이언트 (172.16.150.69)가 시스템 (lksctp-tools-1.0.10-7 .el6.x86_64). 우리는 설립 단계 자체에서 여러 번 ABORT를 얻고 있습니다. 참조 용으로 pcap 세부 정보를 제공하고 있습니다.lk-sctp 연결 설정 중에 ABORT 보내기
