Telnet client

You should probably look at other Kerberos telnet clients as examples ...

That's the output of the krb5_mk_req() function (for more detail, you should
read RFC1510; it explains that it more detail).

>2. what "<authentication-type-pair>" should I send ?

I think that's the bitmask of the authentication types the server support
and the client support (I seem to remember that those get sent by the server
and the client picks one).

>3. should I change the NAME "pete" with my login account "test" or "root" ?

That's up to you; that's the Unix account that the server will try to
login as.  A good telnet client lets you change that somehow.
