Hello,
how to install an kernel module called "statistic" which is made for IPTables firewall?
Module details from IPTables extensions manual page:
I have an Linux CentOS 5.x 64bit OpenVZ server and several virtual private servers (VPSs) on it.statistic
This module matches packets based on some statistic condition. It supports two distinct modes settable with the --mode option.
Supported options:
--mode mode
Set the matching mode of the matching rule, supported modes are random and nth.[!] --probability p
Set the probability for a packet to be randomly matched. It only works with the random mode. p must be within 0.0 and 1.0. The supported granularity is in 1/2147483648th increments.
[!] --every n
Match one packet every nth packet. It works only with the nth mode (see also the --packet option).
--packet p
Set the initial counter value (0 <= p <= n-1, default 0) for the nth mode.
When i did "cat /proc/net/ip_tables_matches" on an VPS it listed iptables modules, but "statistic" one was missing.
On an host node openvz server i did command: modprobe --list | grep stat
and result is:
so i did command on host node openvz server: modprobe xt_statistickernel/arch/x86/kernel/cpu/cpufreq/intel_pstate.ko
kernel/drivers/video/vgastate.ko
kernel/drivers/pcmcia/rsrc_nonstatic.ko
kernel/drivers/cpufreq/cpufreq_stats.ko
kernel/drivers/leds/leds-wm831x-status.ko
kernel/net/netfilter/xt_state.ko
kernel/net/netfilter/xt_statistic.ko
and then i was able to see statistic module in VPSs /proc/net/ip_tables_matches
