====== Squid ======

Enable SNMP-Support for Squid

<code>
snmp_port 3401
acl snmppublic snmp_community public
acl logger src x.x.x.x
snmp_access allow snmppublic logger
snmp_access deny all
</code>

where x.x.x.x is the IP for the host where you will query from.

Restart Squid and test with

<code>snmpwalk -v1 -c public squid-host:3401 .1.3.6.1.4.1.3495.1</code>

and you will see some internal Squid information like this

<code>
SNMPv2-SMI::enterprises.3495.1.1.1.0 = INTEGER: 16360
SNMPv2-SMI::enterprises.3495.1.1.2.0 = INTEGER: 21626872
...
</code>

If you have already installed snmpd, you can use the proxy facility, which allows to redirect SNMP queries. First you have to setup Squid to allow queries from localhost:

<code>
snmp_port 3401
acl snmppublic snmp_community public
snmp_access allow snmppublic localhost
snmp_access deny all
</code>

Again, restart Squid and append to ''/etc/snmp/snmpd.conf'':

<code>proxy -v 1 -c public localhost:3401 .1.3.6.1.4.1.3495.1</code>

and test it from any remote host:

<code>snmpwalk -v1 -c public squid-host .1.3.6.1.4.1.3495.1</code>

Again you should see the snmp walk. Notice, no port information is needed any more, the query is redirected from snmpd to squid.

Too easy...
