a beginner question, what does user@host mean?

do I fill it with myusername@my.website.gateway and why does radius password and lan password mean? why there's two password?

That depends on whether your organization uses 2-factor authentication. If no 2FA, then yes. If you do use 2FA, then don't worry about the myusername@ part, only include my.website.gateway (although, in this case, you will need to provide a session id after --sessionid=).

why does radius password and lan password mean? why there's two password?

I don't use either of those, you shouldn't have to worry about them.

I got this error Traceback (most recent call last): File "./svpn-login.py", line 912, in <module> main(sys.argv) File "./svpn-login.py", line 861, in main session = do_login(host, user, password, dpassword) File "./svpn-login.py", line 472, in do_login client_data = get_vpn_client_data(host) File "./svpn-login.py", line 461, in get_vpn_client_data match = re.search('document.external_data_post_cls.client_data.value = \"([\w=]+)\"', result) File "/home/gaura/anaconda3/lib/python3.8/re.py", line 201, in search return _compile(pattern, flags).search(string) TypeError: cannot use a string pattern on a bytes-like object

Edit: my organization does not use 2FA
