You should not be worried about the license. Just follow it. The license grants you several rights, and as long as you comply with the license, there is no problem deriving a new OS from FreeBSD. Just make sure you don't violate any copyright. Note that I am not a lawyer, and this is no official response from a FreeBSD body. Depending on your local legislation, I suggest you discuss the topic with a lawyer you trust to give you further advice. Also read the legal documents provided by FreeBSD itself and other sources. Read and understand (!) the license itself. http://www.freebsd.org/copyright/freebsd-license.html http://www.freebsd.org/copyright/ http://en.wikipedia.org/wiki/BSD_licenses#2-clause_license_.28.22Simplified_BSD_License.22_or_.22FreeBSD_License.22.29 You may find more specific answers by directing your questions to a legal representative of the FreeBSD foundation or a more appropriate mailing list (-questions@ is for general questions, usually answered by FreeBSD users and contributors). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

No. Not at all. FreeBSD allows free use including modifying.

Re: How i can force a stream socket to wait as limited time inaccept() function?

Please sending for me a sample code that set a timeout
for accept().
///Alireza
Not a complete example, but the concept is there:
int sl, sc;
fd_set rset;
sl=socket();
/*
* listen, bind, etc goes here
*/
flags=fcntl(sl, F_GETFL,0);
flags=fcntl(sl, F_SETFL, flags | O_NONBLOCK);
while(1) {
select(sl+1, rset, 0, 0, tv);
if (FD_ISSET(sl, rset){
accept();
}
}

You need to set the socket descriptor in
non-blocking mode, then call
accept. accept will fail and return -1 with errno
set to EWOULDBLOCK,
the call select(2) on the socket. select will return
when a connection
arrives (you need to test for it) or when the
timeout expires.
I (and everybody else) recommend Unix Network
Programming, 2d Ed by
Rich Stevens. It is THE book for unix programmers.

You don't need to put the socket in non-blocking mode to select for
accept. See example program below.
