Installation is quite straightforward:
rm -fv csf.tgz
tar -xzf csf.tgz
Next, test whether you have the required iptables modules:
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
That's it. You can then configure csf and lfd by edit the files
directly in /etc/csf/*, or on cPanel servers use the WHM UI
csf installation for cPanel is preconfigured to work on a cPanel server with all
the standard cPanel ports open.
csf installation for DirectAdmin is preconfigured to work on a DirectAdmin
server with all the standard DirectAdmin ports open.
csf auto-configures your SSH port on installation where it's running on a non-
csf auto-whitelists your connected IP address where possible on installation.
You should ensure that kernel logging daemon (klogd) is enabled. Typically, VPS
servers 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 readme.txt file for more information.
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 > /etc/csf/csfwebmin.tgz > Install Module
Removing csf and lfd is even more simple:
On cPanel servers:
On DirectAdmin servers:
On generic linux servers:
This perl module is required for Statistical Graphs available from the csf UI.
It is dependent on garphical libraries being installed for your OS (e.g.
libgd, libpng, etc. which is beyond the scope of this document)
The perl module itself can be installed in a variety of ways, e.g.:
# apt-get install libgd-graph-perl
Direct from cpan.org:
# perl -MCPAN -e shell
cpan> install GD::Graph
