SquidGuard is a URL redirector used to use blacklists with the proxysoftware Squid. There are two big advantages to squidguard: it is fast and it is free.
Web Interface

Lighttpd Configuration
If you are using Lighttpd instead of Apache, you'll need to make some modifications to your lighttpd.conf file.
Firstly, you'll need to ensure you have the required modules loaded. At a minimum, you will need:
server.modules = (
"mod_cgi",
"mod_auth",
"mod_alias",
)
<code>
alias.url = (
"/nagios/cgi-bin" => "/usr/local/nagios/sbin",
"/nagios" => "/usr/local/nagios/share"
)
$HTTP["url"] =~ "^/nagios/cgi-bin" {
cgi.assign = ( "" => "" )
}
Add the Authentication configuration:
$HTTP["url"] =~ "^/nagios/cgi-bin" {
auth.backend = "htpasswd"
auth.backend.htpasswd.userfile = "/usr/local/nagios/etc/htpasswd.users"
auth.require = ( "" => (
"method" => "basic",
"realm" => "Nagios Access",
"require" => "user=nagiosadmin"
)
)
}
$HTTP["url"] =~ "^/nagios" {
auth.backend = "htpasswd"
auth.backend.htpasswd.userfile = "/usr/local/nagios/etc/htpasswd.users"
auth.require = ( "" => (
"method" => "basic",
"realm" => "Nagios Access",
"require" => "user=nagiosadmin"
)
)
}
The Lighttpd wiki also has a Nagios installation tutorial.
Password Security
Create the password file and an admin user:
/usr/local/apache2/bin/htpasswd \
-c /usr/local/nagios/etc/htpasswd.users <username>If you don't have the htpasswd program, you can always use one of the web-based programs to create entries for the /usr/local/nagios/etc/htpasswd.users file.
Want to be able to execute commands from the web interface? You'll need to edit /usr/local/nagios/etc/nagios.cfg to enable external commands:
