For example, int one=1; setsockopt (s, SOL_SOCKET, SO_REUSEADDR, &one, sizeof (one)); See getsockopt(2) for further details. I'm afraid I know nothing about the specific JINI programs you mention, but I'd guess that they aren't setting those socket options. -- David Siebörger drs-stable@rucus.ru.ac.za To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
