Ip_pkt_list_tot is a parameter of iptables' module ipt_recent.
I want to use the module recent of iptables and I need to change the parameter ip_pkt_list_tot.

I am using debian with kernal Latest 3.0 (3.0.4-linode36).
I can't find the file /etc/modprobe.conf,so I created one and added
options ipt_recent ip_list_tot=1000 ip_pkt_list_tot=60
but it can't work...
And I tried this.

# modprobe ipt_recent ip_pkt_list_tot=50
FATAL: Module ipt_recent not found.

I've tried looking up info but frankly couldn't find any real information.
Thanks.

The Linode kernels are monolithic, since they can't rely on any particular modules being present within your system. Unless there's another way to modify these parameters at runtime, you might end up having to run a non-Linode kernel to make this happen.

I'm having this same problem on CentOS 5.6 (kernel version of 2.6.39.1-linode34), and I have no idea how to solve it - and I really don't want to resort to a non-Linode kernel unless I absolutely have to.

I do have an /etc/modprobe.conf file, but adding these options to it doesn't change anything. Doing a 'cat /sys/module/xt_recent/parameters/ip_list_tot' still shows the old value.

A poster in this thread suggested modifying these parameters at runtime - how could I do this? Running 'modprobe ipt_recent' or 'modprobe xt_recent' gives errors.

Installing modules on a Linode kernel is apparently possible, but sufficiently difficult to be impractical. So you can't use modprobe to install them.

I put this at the end of my /etc/rc.d/rc.sysinit file:

# change xt_recent module parameters for iptables
chmod 644 /sys/module/xt_recent/parameters/*
echo 300 > /sys/module/xt_recent/parameters/ip_list_tot
echo 60 > /sys/module/xt_recent/parameters/ip_pkt_list_tot

Seems to work so far. I'll post back if I have any problems with it.
