kerberos commnication problem ( on a localhost )

[mdj_kerberos]

hi all,
 
I am setting up kerberos environment on a single machine which is a
part of test network which has no DNS entry!!!

 I am aiming at installing KDC, app server and Client on a single
machine

1. I am able to successfully compile and install kerberos KDC. krb5kdc
and kadmin daemons are running in the background. My kerberos domain
is KERB.COM

2. My /etc/hosts  has
127.0.0.1      localhost.localdomain  localhost

if i type hostname out put is: localhost
  How to change it so that there is no conflict while establishing
communication?

3. To establish a telnet session, i added host/192.168.1.2 principal
and also added a keytab entry using ktadd -k .. host/192..
 is this correct?

4. I have made changes to the xinetd.conf file , but how to restart it
??? :(

5.  I have added the host name using kadmin.local as host/192.168.1.2
>> Is this correct?
please explain the procedure for establishing a telnet server and
client communication .
