 Dear Sir:
        Now I run the server and terminal5 in different host.
   I run echoserver in 192.168.22.115 with ./echo_server -i  and terminal5 in 192.168.22.116 with ./terminal5 -d 192.168.22.115 -i , then I got a error report "sctp_receiveUnsent: unknown value (-5) returned."
Could you give me some advice?
Thank you

Thank you for your advice!
My OS is CentOS5.4.
I change the sctplib with version 1.0.9 , now the echo_server is working fine.But there is a error report when I run the http://www.student.nada.kth.se/~u1djajou/SCTP/terminal5.c and http://www.student.nada.kth.se/~u1djajou/SCTP/terminal6.c , I run it using follow steps:
1  copy terminal5.c to prgrams path (sctplib-1.0.9/sctplib/programs /)
2  compile terminal5.c with command "gcc terminal5.c sctp_wrapper.c -o terminal5 -L/usr/local/lib -lsctplib"
     3  ./terminal5 192.168.22.116 -i (192.168.22.116  is echo_server's ip)
     then I get a error report
     "sctp_send: internal error !
      Floating point exception"
 
      when I run the terminal6.c follow the same steps, I get a error report
     "sctp_associate: an error occured. sctp_associate: an error occured.
      sctp_associate: an error occured.
sctp_associate: an error occured.
sctp_associate: an error occured.
sctp_associate: an error occured.
      sctp_associate: an error occured."
Could you give me some advice?
Thank you
