Fedora vs SuSE sysctl question

Hello everyone, I use Fedora in my work laptop and SuSE at home :) I sent to my email my Fedora's sysctl.conf with contains the values for many network-related kernel parameters. I was just going to append the contents of it to SuSE's /etc/sysconfig/sysctl but after a close inspection I see that the syntax in there is quite different. For example, in Fedora's sysctl.conf, in order to enable syn flood protection I'll have: net.ipv4.tcp_syncookies = 1 On SuSE it's: IP_TCP_SYNCOOKIES="yes" Fedora's way is more intuitive since it reflects the /proc tree. I din't find much information on the sysctl man page (on SuSE). Any one? Thanks in advance, Jorge
