@deusyv this should be fixed with latest master (f07c84d)! Would be nice if you can verify!!!

Sending authentication request
Traceback (most recent call last):
  File "auth.py", line 23, in <module>
    reply = srv.SendPacket(req)
  File "/Users/gic/Virtualenvs/P3P/projects/pyrad/pyrad/client.py", line 180, in SendPacket
    return self._SendPacket(pkt, self.authport)
  File "/Users/gic/Virtualenvs/P3P/projects/pyrad/pyrad/client.py", line 161, in _SendPacket

    if self.dict.attributes[self._DecodeKey(code)].type == 'tlv':
KeyError: 18

After Fix:

Sending authentication request
Access accepted
Attributes returned by server:
Service-Type: ['Framed-User']
Framed-IP-Address: ['192.168.0.1']
Framed-IPv6-Prefix: ['fc66::1/64']
18: [b'motor']

I will generate next version ASAP.

Fixed in 2.3 (https://pypi.org/project/pyrad/)

feedback: upgrading from 2.2 to 2.3 fixed it for me.
