Hi, I´m having almost the same issue as listed in https://github.com/Juniper/net-netconf/issues/37 But already checked to be correctly using 'net/netconf/jnpr'

Here is the script:

    #!/usr/bin/ruby

    require 'pp'
    require 'net/netconf/jnpr'
    require 'junos-ez/stdlib'
    require 'highline/import'

    # Create a hash map to hold login parameters for NetConf session
    login = Hash.new

    # Prompt for system IP, username and password
    login[:target]   = "192.168.108.199"
    login[:username] = ask("username: "){     |a| a.echo = true }

    # Connect to target and start netconf ssh session
    dev = Netconf::SSH.new( login ) 
    dev.open

    Junos::Ez::Provider( dev )

    pp dev.facts.catalog

    dev.close

And here the output:

Any ideas?

Hi @lucasiglesias

I have submitted a pull request to fix the bug you have found.

The problem is with a new method recently added that caused a few methods (including the command method) to masked. This results in method_missing getting called which does not handle the input correctly.

I am having the same issue - unable to use Junos::Ez at all. Any fixes? Running ruby-2.2.2
