DESCRIPTION

3. The TACACS+ packet header

All TACACS+ packets always begin with the following 12 byte header. The header is always cleartext and describes the remainder of the packet:

         1 2 3 4 5 6 7 8  1 2 3 4 5 6 7 8  1 2 3 4 5 6 7 8  1 2 3 4 5 6 7 8

        |version| version|      type      |     seq_no     |   flags        |

METHODS

new( somekey => somevalue)

Construct tacacs+ packet header object

1. if constructing from parameters:

        'version': protocol version
        'type': TAC_PLUS_(AUTHEN|AUTHOR|ACCT) 
        'seq_no': sequencenumber - default 1
        'flags': TAC_PLUS_(UNENCRYPTED_FLAG|SINGLE_CONNECT_FLAG) - default none
        'session_id': session id

2. if constructing from raw packet

        'raw_header': raw packet
decode($raw_data)

Decode $raw_data to version, type, seq_no, flags, session_id, length

raw()

returns raw binary representation of header.

NOTE For complete binary header, length of body must be added.
