Hi,

Aren't both of these parameters to be enabled by default? In version 2.5.1, both were disabled in sysctl.conf.

net.ipv4.tcp_sack = 0
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_window_scaling = 0
net.ipv4.tcp_syn_retries = 3
net.ipv4.tcp_synack_retries = 3

Any reason why both were disabled?

In some scenario, incoming tcp packets were distorted, where Window Scale in tcp options where removed and showed "4 NOP" in trace. Anyone can help to explain as I am still new to this? Thanks.
