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.
