The (Haskell) NetSNMP package is a binding for a subset of the libsnmp api provided by the NetSNMP project. It is initially being developed against NetSNMP version 5.4.1, but probably works with most or all 5.* versions. Currently supported protocol versions: SNMPv1 -- original SNMP SNMPv2c -- v2 protocol with old community-based security Not yet supported: SNMPv3 -- v2 protocol plus new v3 party-based security Other versions are not supported by the underlying library, and are unlikely to ever be supported by this package. SNMPsec -- first attempt to add strong security to SNMPv1 SNMPv2p -- initial SNMPv2, with v2 party-based security SNMPv2u -- v2 protocol with user-based security SNMPv2* -- proprietary hybrid variant of v2c and v2p This binding requires that net-snmp be built without NETSNMP_DISABLE_SNMPV1 or NETSNMP_DISABLE_SNMPV2C. I'd love to support those options, since they may encourage better security, but haven't made the effort. See also: BUGS
