tagged attributes support about pyrad

[GIC-de]

pyrad supports sending of tagged attributes but not receiving

[GIC-de]

Here an example how to parse tagged attributes with current pyrad version. I will try to improve this in future releases:

...
import struct
...

class FakeServer(server.Server):

    def HandleAuthPacket(self, pkt):
        print("Received an authentication request")
        print("Attributes: ")
        for attr in pkt.keys():
            def print_attributes(attr, value):
                # check if attribute has tag
                if self.dict[attr].has_tag:
                    # unpack tag and value
                    fmt = "B%ds" % (len(value) - 1)
                    _attr = struct.unpack_from(fmt, value, 0)
                    tag = _attr[0]
                    value = "".join(_attr[1:])
                    # print output
                    print("%s:%s = %s" % (attr, tag, value))
                else:
                    print("%s = %s" % (attr, value))

            # check if attribute value is list
            if isinstance(pkt[attr], list):
                for v in pkt[attr]:
                    print_attributes(attr, v)
            else:
                print_attributes(attr, pkt[attr])

This issue keeps open because support for receiving tagged attributes is still missing.
