Shalom I've been thinking of converting my TCP-based code generator to SCTP. Finding info on SCTP is not as easy though as TCP. Have you used SCTP? On openSUSE, I can compile this: int sd=::socket(PF_INET,SOCK_STREAM,IPPROTO_SCTP); with just this file: https://github.com/Ebenezer-group/onwards/blob/master/src/cmw/Buffer.hh but on FreeBSD, I have to also #include<netinet/sctp.h> . Are there other Posix systems where you have to include that file? I read that "SCTP frequently sends heartbeat messages to test the state of connection." I'm not sure I want it to do that frequently. Is that configurable? Thank you in advance. Brian Ebenezer Enterprises - Want to get out of Murderapolis?
