Please cc me, as I'm not on this list. I am using 4.3-RELEASE, and investigating why I don't see any keepalives (using tcpdump) on my connections. The default values are as follows: net.inet.tcp.keepidle = 7200000 net.inet.tcp.keepintvl = 75000 It seems to me that the keepalive interval is being set by keepidle, thus setting keepidle = 20000, generates keepalives at 20s intervals. Looking at the comments in tcp_var.h, it should be keepintvl that sets this interval. Otherwise, why have such a large value for keepidle? Is this a bug? Or have I missed something, Many thanks, Rich. -- Richard Smith Network Systems Director Satamatics Ltd Green Lane, Tewkesbury, GL20 8HD, United Kingdom Tel: +44 1684 278610 Fax: +44 1684 278611 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
