CHANGELOG

master

0.6.4

Making the octet string in msgAuthenticationParameters 0-length when no authentication is to happen (some SNMP implementations are quite strict in this point).

0.6.3

  • The OidNotFound exception is now raised when a response PDU is received with an empty value.

0.6.2

Improvements

  • extended use of RBS signatures (thx to openssl RBS signatures).

Bugfixes

  • fixed mib loading when there are no imports.
  • fixed default mibs by including subdirs of /usr/share/snmp/mibs (in debian, snmp mibs get loaded under /iana and /ietf)

0.6.1

Bugfixes

Removed MSG_NOSIGNAL flag from udp socket send calls, given that it's unnecessary for UDP transactions, it's not defined in all environments, like Mac OS.

0.6.0

Features

netsnmp supports SHA256 as an authentication protocol. You can pass :sha256 to the :auth_protocol argument, as an alternative too :sha or :md5. (#29)

0.5.0

Improvements

  • Using the sendmsg and recvmsg family of socket APIs, which allow for connectionless-oriented communication, and do not require the response packets coming from the same host:port pair (which some old SNMP agents do).

Bugfixes

  • Fixed corruption of authenticated PDUs when performing auth param substitution in the payload, which was reported as causinng decryption error report PDUs being sent back.

0.4.2

Improvements

Errors of the usmStats family will now raise an exception, where the message will be the same as netsnmp message for the same use-case (#50).

0.4.1

fixed: namespace scope-based MIB lookups weren't working for custom-loaded MIBs (#48)

0.4.0

Features

  • New debugging logs: NETSNMP::Client.new(..., debug: $stderr, debug_level: 2) (can also be activated with envvar, i.e. NETSNMP_DEBUG=2);

Improvements

  • octet strings are now returned in the original encoding; Binary strings are now returned as an "hex-string", which will be a normal string, but it'll print in hexa format, a la netsnmp.

Bugfixes

  • incoming v3 message security level is now used to decide whether to decrypt/authorize (it was taking the send security level into account);
  • reacting to incoming REPORT pdu with IdNotInTimeWindow OID by updating the time and replay request PDU (something common to Cisco Routers);
  • Fiterling out unused bits from V3 message flags;

0.3.0

  • MIB Parser.
  • methods can use MIBs as well as OIDs.
client.get(oid: "sysName.0")

0.2.0

  • Fix kwargs issues, enabling ruby 3.
  • RBS type signatures.
  • Bye Travis, hello Github Actions.

0.1.9

  • Fix the encoding of gauge/counter32 ASN values.

0.1.8

  • Fix for Timeticks with smaller values.

0.1.7

  • Fixed padding of counter/gauge varbinds.

0.1.6

  • Added support for 64bit varbinds, such as Counter64.

0.1.5

  • Added NETSNMP#inform to send INFORM PDUs as well.
  • Fixed encoding for counter32/gauge types for >16bit numbers.
  • Fixed encryption of PDU packets when data's not a multiplier of 8.

0.1.4

  • Fixed unexisting Timeout::Error constant, as "timeout" wasn't being required.
  • Allow returning multiple varbind values, when more than one PDU is sent.
  • Added proper support for Gauge/Counter32.
  • Added support for SNMPv3 timeliness.

0.1.3

  • Added the NETSNMP::Timetick entity, which coerces into a numeric.

0.1.2

  • Fixes for propagation of error, specific error message for unrecognized SNMP error codes as well.
  • encode octet strings to UTF-8

0.1.1

  • IPAddress varbind values will be converted from and to IPAddr objects.

0.1.0

  • netsnmp gem goes public.
  • rewrite of FFI logic into pure ruby, handling ASN1 encoding via openssl gem.

0.0.2

  • Fixing timeout issues.

0.0.1

  • First version, FFI-based (using C libnetsnmp).
  • (This version was very buggy, and isn't recommended for production usage).
