Can I change the value of those parameters (spoofprotect, syncookies, dynaddr_hack, notimestamps, nobroadcasticmpecho, ip_forward) from sysctl.conf file in systemd?

  • What do you mean "from sysctl.conf"? Does it mean change those value by editing sysctl.conf file? – cuonglm Apr 28 '14 at 16:14
  • in system based on initd, we can change those values in /etc/network/options. But for systems based on systemd, this file no longer exist. And this is my question , how can we modify those values ? can we do that from sysctl.conf file ? – Bingo Apr 29 '14 at 6:49

From this link, I see that, these values can be edited.

ip_forward=no
ipv6_forward=no
spoofprotect=yes
syncookies=no

The above variables can now be set in /etc/sysctl.conf which is acceseble via the System configuration menu, System variables.

From this answer, I see changing net.ipv4.icmp_echo_ignore_broadcasts is not going to change anything.

For timestamp, I believe you refer to the system variable net.ipv4.tcp_timestamps. As per this link, it is suggested to leave it turned on unless if you live on an extremely slow connection such as a 56 kbps modem connection to the internet.
