netmiko connecting to arista devices.

[dan1962]

Creating a Python script that will log into a Arista Switch, from there it will save config, then tftp to a tftp server and copy the running-config.

Issue that I am having is that it will not connect to the Arista Device.
Getting this error:
netmiko.ssh_exception.NetmikoAuthenticationException: Authentication failure: unable to connect arista_eos 192.168.225.254:22
Bad authentication type; allowed types: ['publickey', 'keyboard-interactive']

My code:

from netmiko import ConnectHandler

iosv_l2 = {
    'device_type': 'arista_eos',
    'ip': '192.168.225.254',
    'username': 'test123',
    'password': 'test123'
}

Not using keys yet, and can log onto the device with username and password from a command prompt or 'Putty'
I looked over the base_connection.py file, but do not want to modify anything until I know what the issue is.

Thank you

Dan
