Introduzione
Dato che ho fatto fatica a creare una configurazione funzionante per squid che comprenda solo il proxyng (no caching) ed il monitoring tramite snmp, la posto qui come riferimento per me e gli altri.
Requisiti
- Squid 2.6
- snmp-tools (solo se si vuole abilitare il monitoring tramite snmp)
- snmpd (solo se si vuole abilitare il monitoring tramite snmp)
- mrtg (solo se si vuole abilitare il monitoring tramite snmp)
Configurazione
- /etc/squid.conf

La mib SQUID_MIB.txt (che io ho rinominato per comodita’) la si trova sotto /usr/share/squid/mib.txt
