| − | == Configurar un Proxy o DnsServices per bloquejar publicitat ==
| |
| − | === Introducció ===
| |
| − | Configurarem un servidor DNSServices (bind9) / Proxy3 / Cloudy per que elimini els anuncis de les pàgines web.
| |
| | | | |
| − | === Requisits ===
| |
| − | Es parteix d'un servidor [[Debian]]/[[Ubuntu]]/[[Cloudy]] configurat amb [[Servidor Proxy guifi-proxy3]].
| |
| − |
| |
| − | == Instal·lació i configuració ==
| |
| − | Entrem per ssh a la màquina:
| |
| − | * Actualitzem els paquets
| |
| − | apt-get update
| |
| − | apt-get upgrade
| |
| − | === Instal·lació de freeradius ===
| |
| − | * Instal·lem el paquet freeRADIUS i les dependencies
| |
| − | apt-get install freeradius
| |
| − | * Instal·lem el mòdul ldap
| |
| − | apt-get install freeradius-ldap
| |
| − | === Configurar freeradius ===
| |
| − | * Editem l'arxiu de configuració <code>/etc/freeradius/radiusd.conf</code>
| |
| − | No s'utilitza EAP, eliminem la linea <code>$INCLUDE eap.conf</code>. Excepte això, la resta de l'arxiu <code>radiusd.conf</code> queda per defecte.

| |
| − | * Editem l'arxiu de configuració <code>/etc/freeradius/modules/ldap</code>

| |
| − | * Editem l'arxiu de configuració <code>/etc/freeradius/sites-available/default</code>
| |
| − | Editem l'arxiu <code>default</code>, assegurant-nos que <code>ldap</code> queda inclòs a les seccions "authorize" i "authenticate". Suprimim altres opcions com ara "unix" dins d'aquestes seccions.

| − | * Editem l'arxiu de configuració <code>/etc/freeradius/sites-available/inner-tunnel</code>
| |
| − | Fem el mateix amb l'arxiu <code>inner-tunnel</code>
