#6 Re: Secure Networking within kernel Posted by Anonymous (81.57.xx.xx) on Tue 27 Sep 2005 at 16:19 Some others that might be of interest for this topic: /proc/sys/net/ipv4/icmp_ratelimit /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses /proc/sys/net/ipv4/conf/*/log_martians /proc/sys/net/ipv4/conf/*/accept_redirects /proc/sys/net/ipv4/conf/*/accept_source_route For a complete reference of kernel IP tunable sysctls, see /usr/src/linux-2.6.11.12/Documentation/networking/ip-sysctl.txt To reply another comment: you don't need to reboot in order to apply on the fly /etc/sysctl.conf modifications: sysctl -p /etc/sysctl.conf # is enough By the way, setting all those params on /etc/sysctl.conf is imho the proper way to do it. One should never try to override (or be overriden by ? are your scripts started before procps ? take care !) a standard config file.
