privacy protocol (des|aes) and privacy protocol pass phrase #2

Closed naquad closed 12 years ago

Hi.

I can't find how to set privacy protocol and privacy protocol pass phrase in net-snmp. Is there some way?

Just trying to do the same as snmpget -v3 -a MD5 -A 'xxxx1' -u user -x AES -X 'xxx2' -l authPriv example.com .1.3.6.1.4.1.2021.4.5.0 does, but with net-snmp.

Tried that:

#!/usr/bin/ruby -w

require 'net-snmp'

Net::SNMP::Session.open(:peername => 'example.com',
                        :version => '3',
                        :security_level => Net::SNMP::Constants::SNMP_SEC_LEVEL_AUTHPRIV,
                        :auth_protocol => :md5,
                        :priv_protocol => :aes,
                        :username => 'user',
                        :password => 'xxx1') do |sess|

  pdu = sess.get([".1.3.6.1.4.1.2021.4.5.0"])
  pdu.print
end

and i get error:

I suspect this happens because I didn't set privacy protocol and privacy pass phrase.

Thanks.

I cut a new release with options auth_password and priv_password. Closing.
