TCP Settings

To tune the TCP/IP settings, follow these steps:

1. Add the following entry to /etc/rc.local:

   echo 30 > /proc/sys/net/ipv4/tcp_fin_timeout echo 60 > /proc/sys/net/ipv4/tcp_keepalive_time echo 75 > /proc/sys/net/ipv4/tcp_keepalive_intvl echo 0 > /proc/sys/net/ipv4/tcp_window_scaling

2. Add the following to /etc/sysctl.conf:

   net.ipv4.ip_local_port_range = 1204 65000 net.core.rmem_max = 8388608 net.ipv4.tcp_rmem = 4096 131072 8388608 net.ipv4.tcp_wmem = 4096 131072 8388608 net.ipv4.tcp_sack = 0 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_window_scaling = 0 net.ipv4.tcp_keepalive_time = 60 net.ipv4.tcp_keepalive_intvl = 75 net.ipv4.tcp_fin_timeout = 30

3. Add the following as the last entry in /etc/rc.local:

   sysctl -p /etc/sysctl.conf

4. Reboot the system.
