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.
