Dear Sir or Madam,

Sorry for inconvenient of my silly question, but I can't ask other.

I am trying to build telnet client application to Mandrake Linux, the
problem is that

the server gives me :

FF FA 25 01 02 06 02 02 02 FF F0 (what is meant by 02 06 02 02 02 0 ?)
I can't convert the meaning from RFC 2942 :
  IAC SB AUTHENTICATION SEND
  KERBEROS_V5 CLIENT|MUTUAL
  KERBEROS_V5 CLIENT|ONE_WAY IAC
  SE

what should I give to the server ( I can not implement the below RFC
procedure ):

    IAC SB AUTHENTICATION NAME
       "pete" IAC SE
       IAC SB AUTHENTICATION IS
       KERBEROS_V5 CLIENT|MUTUAL AUTH
       <KRB_AP_REQ message> IAC SE

my implementation is (without KRB_AP_REQ message), I have an account as
"riki":

FF FA 25 03 "riki" FF F0
FF FA 25 0 02 06 02 02 02 FF F0

but rejected by the server, it sends me : FF FA 25 02 02 06 01 FF F0

and what is the value of "what is KRB_AP_REQ message" and what is kerberos
ticket in this case ?
where can I find the value ?

Thank You very much for help.

Best Regards
Riki
