Hi methyl,

Thanks for your response. Requested output is as below.

Note that there are two telnet attempts below. The first is using the hostname and the second is using the IP address. I was expecting both to behave the same, i.e., use the /etc/hosts file entry but that does not seem to be happening.

The first telnet using the hostname is connecting via the DNS and the second telnet using the IP address is connecting via the /etc/hosts file. This is my assumption. I can tell that the first telnet is using the one from the DNS server because I don't see the HP-UX banner while the second telnet attempt is showing the HP-UX banner. The HP-UX server is the one that am wanting to connect to.

Code:

root@server2:(root)> cat /etc/nsswitch.conf
#
# /etc/nsswitch.files:
#
# An example file that could be copied over to /etc/nsswitch.conf; it
# does not use any name services.
#
hosts: files [NOTFOUND=continue UNAVAIL=continue TRYAGAIN=continue] dns

asadmin-stop-instance(1AS)					   User Commands					asadmin-stop-instance(1AS)

NAME

       asadmin-stop-instance, stop-instance - stops the specified server instance and all the services associated with it

SYNOPSIS

       stop-instance  [--user  admin_user]  [--password  admin_password]  [--host local_host] [--port 4848] [--local=false] [--domain domain_name]
       [--secure|-s]instance_name

       Use the stop-instance to stop the instance with the instance name specified. The stop-instance can be run both locally and  remotely.   The
       named instance must already exist within the given domain; and the instance must be running.

OPTIONS

       --user		       administrative user associated for the instance.

       --password	       administrative password corresponding to the administrative user.

       --host		       host name of the machine hosting the administrative instance.

       --port		       administrative port number associated with the administrative host.

       --local		       determines if the command should delegate the request to administrative instance or run locally.

       --domain 	       name of the domain.

       --passwordfile	       file containing passwords appropriate for the command (e.g., administrative instance).

       --secure 	       if true, uses SSL/TLS to communicate with the administrative instance.

OPERANDS

       instance_name	       name of the instance to be stopped.

       Example 1: Using stop-instance in local mode

       asadmin> stop-instance --local --domain domain1 server1
       Instance server1 stopped

       Where: the server1 instance associated with the domain1 domain is stopped locally.

       Example 2: Using stop-instance in remote mode

       asadmin> stop-instance --user admin --password bluestar --host localhost --port 4848 server1
       Instance server1 stopped

       Where: the server1 instance associated with the named user, password, host and port is deleted from the remote machine.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command
