/etc/sysctl.conf file

Hi,

usually you enable things like IP forwarding in /etc/sysctl.conf. Now I read through the UFW firewall documentation, and regarding to that, it has it's own sysctl.conf file in /etc/ufw.

Why is that? What happens if I enable UFW and have things configured in /etc/sysctl.conf? Will UFW overrule these settings with whatever is in /etc/ufw/sysctl.conf?

I'm trying to make some changes to sysctl on an Android phone (LG Thrill). I've rooted the phone and am using the stock ROM (and would prefer to stick with the stock ROM if possible). Unfortunately, there is no sysctl.conf file for me to work with present on the phone. Sysctl itself is present though and I can make changes via terminal, though those changes are not persistent across reboots.

What's the location of the sysctl.conf file on lion? In Snow Leopard it was in /etc/sysctl.conf but now that folder doesn't contain it anymore. Searching for the file in spotlight yields no results.

Have the shared memory settings been moved to a different conf file? What is it's name?

EDIT

I am trying to modify the kernel shared memory settings of the machine.

I'm using 12.04 LTS and can sudo sysctl to set swappiness to 10, but adding vm.swappiness=10 to sysctl.conf doesn't work for me - after I reboot, swappiness still reports 60 (default)

I'd like to be able to reduce swaps to my SSD, but can't find a way to do so except manually per session.

I have a defined type at modules/sysctl/manifests/init.pp that looks like:

define sysctl ( $value = undef, $ensure = undef ) {

# Parent purged directory include sysctl::base

# The permanent change file { "/etc/sysctl.d/${title}.conf": owner => 'root', group => 'root', mode => '0644', content => "${title} = ${value}\n", ensure => $ensure, notify => Exec["

Hello everyone

I've modified sysctl.conf and now reboot F17 gives me at start up

Failed to start Apply Kernel Variables See 'systemctl status systemd-sysctl.service' for details.

trying systemctl status systemd-sysctl.service gives me

On my Ubuntu machine, in /etc/sysctl.conf file, I've got reverse path filtering options commented out by default like this:

#net.ipv4.conf.default.rp_filter=1 #net.ipv4.conf.all.rp_filter=1

but in /etc/sysctl.d/10-network-security.conf they are (again, by default) not commented out:

net.ipv4.conf.default.rp_filter=1 net.ipv4.conf.all.rp_filter=1

So is reverse path filtering enabled or not?

Just link coredump.conf to /dev/null then apply with sysctl :# ln -s /dev/null /etc/sysctl.d/coredump.conf# /lib/systemd/systemd-sysctl
