I'm not sure about anything when it comes to SNMP.

After copying mib.txt to $prefix/share/snmp/mibs, then running
snmpwalk (v5.0.7) I get:

    % /tmp/local/bin/snmpwalk -v 1 -c public -m SQUID-MIB bo2:3401 squid
    squid: Unknown Object Identifier (Sub-id not found: (top) -> squid)

ktrace shows that snmpwalk reads my SQUID-MIB.txt file, but apparently
ignores it for some reason.

If I change the file so that it looks like this at the top:

    SQUID-MIB DEFINITIONS ::= BEGIN
    enterprises OBJECT IDENTIFIER ::= { iso org(3) dod(6) internet(1) private(4) > 1 }
    nlanr OBJECT IDENTIFIER ::= { enterprises 3495 }

then it works better:

    % /tmp/local/bin/snmpwalk -v 1 -c public -m SQUID-MIB bo2:3401 squid |& head
    SQUID-MIB::cacheSysVMsize.0 = INTEGER: 7996
    SQUID-MIB::cacheSysStorage.0 = INTEGER: 19353283
    SQUID-MIB::cacheUptime.0 = Timeticks: (80748) 0:13:27.48
    ...

(I guess the -m SQUID-MIB is unnecessary anyway)

Also note that if I use "-v 2c" instead, I get no response from Squid.
Actually, tcpdump shows Squid sending replies, but snmpwalk ignores
them and reports:

    Timeout: No Response from bo2:3401
