Installation ============ Installation is quite straightforward: cd /usr/src rm -fv csf.tgz wget https://download.configserver.com/csf.tgz tar -xzf csf.tgz cd csf sh install.sh Next, test whether you have the required iptables modules: perl /usr/local/csf/bin/csftest.pl Don't worry if you cannot run all the features, so long as the script doesn't report any FATAL errors You should not run any other iptables firewall configuration script. For example, if you previously used APF+BFD you can remove the combination (which you will need to do if you have them installed otherwise they will conflict): sh /usr/local/csf/bin/remove_apf_bfd.sh That's it. You can then configure csf and lfd by reading the documentation and configuration files in /etc/csf/csf.conf and /etc/csf/readme.txt directly or through the csf User Interface. csf installation for cPanel and DirectAdmin is preconfigured to work on those servers with all the standard ports open. csf auto-configures your SSH port on installation where it's running on a non- standard port. csf auto-whitelists your connected IP address where possible on installation. You should ensure that kernel logging daemon (klogd) is enabled. Typically, VPS servers running RedHat/CentOS v5 have this disabled and you should check /etc/init.d/syslog and make sure that any klogd lines are not commented out. If you change the file, remember to restart syslog. See the csf.conf and readme.txt files for more information. Perl Modules ============ While most should be installed on a standard perl installation the following may need to be installed manually: # On rpm based systems: yum install perl-libwww-perl.noarch perl-LWP-Protocol-https.noarch perl-GDGraph # On APT based systems: apt-get install libwww-perl liblwp-protocol-https-perl libgd-graph-perl # Via cpan: perl -MCPAN -eshell cpan> install LWP LWP::Protocol::https GD::Graph InterWorx ========= 1. Enable csf in InterWorx > NodeWorx > Plugins > csf 2. See the InterWorx section in /etc/csf/readme.txt Webmin Module Installation/Upgrade ================================== To install or upgrade the csf webmin module: Install csf as above Install the csf webmin module in: Webmin > Webmin Configuration > Webmin Modules > From local file > /usr/local/csf/csfwebmin.tgz > Install Module Uninstallation ============== Removing csf and lfd is even more simple: cd /etc/csf sh uninstall.sh
