He wants the connection to be closed after a certain number of seconds if it is idle. Lefterius, when you read() from the socket, call time(). If you read more than zero bytes, save that time in a variable. If you read zero bytes, compare what time it is now to the saved value, and if the delta is greater than when you want an idle connection to close, well, call close() and exit or whatever. Details like initializing the variable to now beforehand are probably needed. -- -Chuck ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Is there any easy way to setup IO timeouts (read/write) for a socket to close in case of inactivity? ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

They do not specify time after which socket should be closed, if no IO is done. The do limit time the process can block on the socket. So, if you do read() from this socket and it blocks, it will resume after 4 seconds even if no input is present. -- Totus tuus, Glebius.

setsockopt and SO_RCV/SNDTIMEO
Hi, I am trying to set something like this up but it doesn't seem to work as I expect it (unless I expect wrong): timeout.tv_sec = 4; timeout.tv_usec = 0; if(setsockopt(listenSocket, SOL_SOCKET, SO_RCVTIMEO, (void *)&timeout, sizeof(timeout)) == -1) fprintf(stdout, "setsockopt SO_RCVTIMEO failed: %s\n", strerror(errno)); if(setsockopt(listenSocket, SOL_SOCKET, SO_SNDTIMEO, (void *)&timeout, sizeof(timeout)) == -1) fprintf(stdout, "setsockopt SO_SNDTIMEO failed: %s\n", strerror(errno)); When I telnet to the socket, the socket always stays connected. The timer doesn't seem to work right. Am I missing anything here or is this broken?
