Fortinet Accept Disclaimer After Login still not working in Netmiko 3.4.0

Hello everyone,

I have a Fortigate running with banner and “post-login-banner” enabled. I’m facing the same Socket Error. It seems that this session_preparation function which was tweaked in 2019 doesn’t work for my case. Last issue I found about that:

`aws_us_dev1 = { “device_type”: ‘fortinet’, “host”: “x.x.x.x”, “username”: username, “password”: password, “fast_cli”: True }

aws_us_dev2 = { “device_type”: ‘fortinet’, “host”: “x.x.x.x”, “username”: username, “password”: password, “fast_cli”: True }

elif site == ‘aws-us’ and env == ‘qa’: for device in (aws_us_dev1, aws_us_dev2): net_connect = Netmiko(**device) print(net_connect.find_prompt()) output = net_connect.send_command(command) url_references = url_pattern.finditer(output) for url_reference in url_references: print(url_reference.group(1)) match = True if not match: print(“URL não encontrada”) `

– Error:

Correct.

Netmiko 4.1.0 and PY3.7.2

Hi Kirk,

It worked after upgrade to Python3.7 via pyenv.

Thanks a lot!
