Server box (F9) has: # Controls the use of TCP syncookies net.ipv4.tcp_syncookies = 1 timestamp of /etc/sysctl.conf: 2008-05-15, installation default i think. Other (F8) box has: # Controls the use of TCP syncookies net.ipv4.tcp_syncookies = 0 timestamp of /etc/sysctl.conf: 2007-01-28, touched 1.5 years ago. Have not checked the install defaults - if i touched them it was a long time ago.
