Peter_Johan 26 Posted February 28, 2013 Share Posted February 28, 2013 [root@centos /]# sysctl net.ip4v.tcp_syncookies error: "net.ip4v.tcp_syncookies" is an unknown key in Centos 6 the issue may be that I'm following a slightly old manual (2009) which more often refers to Fedora/RHEL and very rarely Centos. the key does exist under the path, I'm looking at it.. Thanks in advance for your help :-) 18 Quote Link to post Share on other sites

inittux 1,367 Posted March 1, 2013 Share Posted March 1, 2013 Welcome to the forums! sorry for late reply. forums haven't been very active. Glad you figured it out. You can join our irc channel. irc.foreverchat.net #linux and the linux mint channel (donno what server though) there seems to be nice people too. 3 Quote Link to post Share on other sites
hybrid 189 Posted March 11, 2013 Share Posted March 11, 2013 Welcome to the forums! We're glad to have you here! sysctl net.ip4v.tcp_syncookies You've already noticed and pointed out that the issue here was mistyping ipv4 as ip4v, but I thought I'd clarify that was the issue here for anyone else reading. It happens to us all. 3 Quote Link to post Share on other sites
