Binary package hint: procps
Since net.ipv4.tcp_syncookies was enabled as default in procps 3.2.7-11ubuntu1 18/03/2009 i have been getting a message of which procps is restarted
* Setting kernel variables (/etc/sysctl.conf)... [ OK ]
* Setting kernel variables (/etc/sysctl.d/10-console-messages.conf)... [ OK ]
* Setting kernel variables (/etc/sysctl.d/10-network-security.conf)...
error: "net.ipv4.tcp_syncookies" is an unknown key
[fail]
I am on the latest kernel of 2.6.28-11.36
This is the contents of my 10-network-security.conf
# prevent some spoofing attacks.
net.ipv4.conf.default.rp_filter=1
net.ipv4.conf.all.rp_filter=1
# Turn on SYN-flood protections. Starting with 2.6.26, there is no loss
# of TCP functionality/features under normal conditions. When flood
# protections kick in under high unanswered-SYN load, the system
# should remain more stable, with a trade off of some loss of TCP
# functionality/features (e.g. TCP Window scaling).
net.ipv4.tcp_syncookies=1
This is also a possible occurance from enabling it by default when it was originally came from bug 50791 https://launchpad.net/bugs/57091 . |
