=====MIBs=====

====Add a MIB====

Example :

<code>
# cd /usr/share/snmp/mibs
# cp /tmp/squid.txt .
# head -n1 squid.txt
-- SQUID-MIB  { iso org(3) dod(6) internet(1) private(4) enterprises(1) 3495 }
# echo "SQUID-MIB squid.txt" >> .index
# echo "mibs +SQUID-MIB" >> /etc/snmp/snmp.conf
</code>

=====Extend Net-SNMP with scripts=====
