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.

root@server2:(root)> cat /etc/nsswitch.conf

# An example file that could be copied over to /etc/nsswitch.conf; it

locktest

LOCKTEST(1)							    Test Suite							       LOCKTEST(1)

NAME

       locktest - Find differences in locking between two SMB servers

SYNOPSIS

       locktest {//server1/share1} {//server2/share2} [-U user%pass] [-U user%pass] [-s seed] [-o numops] [-a] [-O] [-E] [-Z] [-R range] [-B base]
		[-M min]

DESCRIPTION

       locktest is a utility for detecting differences in behaviour in locking between SMB servers. It will run a random set of locking operations
       against //server1/share1 and then the same random set against //server2/share2 and display the differences in the responses it gets.

       This utility is used by the Samba team to find differences in behaviour between Samba and Windows servers.

OPTIONS

       -U user%pass
	   Specify the user and password to use when logging on on the shares. This parameter can be specified twice (once for the first server,
	   once for the second).

       -s seed
	   Seed the random number generator with the specified value.

       -o numops
	   Set the number of operations to perform.

       -a
	   Print the operations that are performed.

       -A
	   Backtrack to find minimal number of operations required to make the response to a certain call differ.

       -O
	   Enable oplocks.

       -u
	   Hide unlock fails.

       -E
	   enable exact error code checking

       -Z
	   enable the zero/zero lock

       -R range
	   set lock range

       -B base
	   set lock base

       -M min
	   set min lock length

       -k
	   Use kerberos

       This man page is correct for version 4.0 of the Samba suite.
