Hi,
I'm trying to dynamically determine the tcp windowsize. Sysctl
has the following to say, but the name/value pairs are not
documented.
net.inet.tcp.rfc1323: 0
net.inet.tcp.rfc1644: 0
net.inet.tcp.mssdflt: 512
net.inet.tcp.rttdflt: 3
net.inet.tcp.keepidle: 14400
net.inet.tcp.keepintvl: 150
net.inet.tcp.sendspace: 16384
net.inet.tcp.recvspace: 16384
net.inet.tcp.keepinit: 150
net.inet.tcp.log_in_vain: 0
net.inet.tcp.delayed_ack: 1
net.inet.tcp.path_mtu_discovery: 1
net.inet.tcp.pcbcount: 156
net.inet.tcp.always_keepalive: 1
The rfc values are self-explanatory...
send/recv space might be what I'm looking for...
delayed ack sounds interesting....
Any comments, documentation, or pointers are much appreciated. I'm
now off to dig through the kernel...
Thanks,
john
