Installing ConfigServer Firewall (CSF)

http://configserver.com/cp/csf.html

If you get the following error during installation:

Checking Perl modules...
Can't locate LWP/UserAgent.pm in @INC (@INC contains: /etc/csf /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 .) at (eval 19) line 2.

Then you need to install perl-libwww-perl package (as well as its prerequisites).

yum install perl-Compress-Zlib perl-HTML-Tagset perl-URI perl-HTML-Parser perl-libwww-perl
