Hi Don,
What we are trying to create is a master script to run other scripts in the back ground on different machines.

to answer your questions
Code:
$host

are the host names of the 3 machines ws1 ws2 ws3. and
Code:
$process.sh

is the script name located on the NIS server which is the 4th machine making the initial call script. So all machines can see and access the script and its not written on each machine saving up needed space.

hope that answered the questions: now I have got some interesting results with the code for rsh

host names are config with Csh which is stty not supported for transit. (not sure what I just said but hope it helps)
and i have a ambiguous output redirect.

IE @Don you mentioned the direct to the null. Short answer is we don't care what the output is from the call, the script outputs to a different files those files are what we are after. But I think your right about having it directed to that null.

The rsh call stops and on the ws4 and creates a PID and waits until never (endless loop in script tracking memory) have to suspend and kill pid to stop it. again its not the problem but it stopping in the master script is.

any ideas I can research in to please throw them at me too. Thanks OJT scripting got to love it.

nisserver(1M)                                             System Administration Commands                                             nisserver(1M)

NAME
nisserver - set up NIS+ servers SYNOPSIS
/usr/lib/nis/nisserver -r [-x] [-f] [-v] [-Y] [ -d NIS+_domain] [ -g NIS+_groupname] [-l network_passwd] /usr/lib/nis/nisserver -M [-x] [-f] [-v] [-Y] -d NIS+_domain [ -g NIS+_groupname] [ -h NIS+_server_host] /usr/lib/nis/nisserver -R [-x] [-f] [-v] [-Y] [ -d NIS+_domain] [ -h NIS+_server_host] DESCRIPTION
The nisserver shell script can be used to set up a root master, non-root master, and replica NIS+ server with level 2 security (DES). If other authentication mechanisms are configured with nisauthconf(1M), nisserver will set up a NIS+ server using those mechanisms. nisauth- conf(1M) should be used before nisserver. When setting up a new domain, this script creates the NIS+ directories (including groups_dir and org_dir) and system table objects for the domain specified. It does not populate the tables. nispopulate(1M) must be used to populate the tables. OPTIONS
-d NIS+_domain Specifies the name for the NIS+ domain. The default is your local domain. -f Forces the NIS+ server setup without prompting for confirmation. -g NIS+_groupname Specifies the NIS+ group name for the new domain. This option is not valid with -R option. The default group is admin.<domain>. -h NIS+_server_host Specifies the hostname for the NIS+ server. It must be a valid host in the local domain. Use a fully qualified hostname (for example, hostx.xyz.sun.com.) to specify a host outside of your local domain. This option is only used for setting up non-root master or replica servers. The default for non-root master server setup is to use the same list of servers as the parent domain. The default for replica server setup is the local hostname. -l network_password Specifies the network password with which to create the credentials for the root master server. This option is only used for master root server setup (-r option). If this option is not specified, the script prompts you for the login password. -M Sets up the specified host as a master server. Make sure that rpc.nisd(1M) is running on the new master server before this command is executed. -R Sets up the specified host as a replica server. Make sure that rpc.nisd is running on the new replica server. -r Sets up the server as a root master server. Use the -R option to set up a root replica server. -v Runs the script in verbose mode. -x Turns the echo mode on. The script just prints the commands that it would have executed. Note that the commands are not actually executed. The default is off. -Y Sets up a NIS+ server with NIS-compatibility mode. The default is to set up the server without NIS-compatibility mode. USAGE
Use the first synopsis of the command (-r) to set up a root master server. To run the command, you must be logged in as super-user on the server machine. Use the second synopsis of the command (-M) to set up a non-root master server for the specified domain. To run the command, you must be logged in as a NIS+ principal on a NIS+ machine and have write permission to the parent directory of the domain that you are setting up. The new non-root master server machine must already be an NIS+ client (see nisclient(1M)) and have the rpc.nisd(1M) daemon running. Use the third synopsis of the command (-R) to set up a replica server for both root and non-root domains. To run the command, you must be logged in as a NIS+ principal on a NIS+ machine and have write permission to the parent directory of the domain that you are replicating. The new non-root replica server machine must already be an NIS+ client and have the rpc.nisd daemon running. EXAMPLES
Example 1: Setting up Servers To set up a root master server for domain sun.com.: root_server# /usr/lib/nis/nisserver -r -d sun.com. For the following examples make sure that the new servers are NIS+ clients and that rpc.nisd is running on these hosts before executing nisserver. To set up a replica server for the sun.com. domain on host sunreplica: root_server# /usr/lib/nis/nisserver -R -d sun.com. -h sunrep To set up a non-root master server for domain xyz.sun.com. on host sunxyz with the NIS+ groupname as admin-mgr.xyz.sun.com.: root_server# /usr/lib/nis/nisserver -M -d xyz.sun.com. -h sunxyz -g admin-mgr.xyz.sun.com. To set up a non-root replica server for domain xyz.sun.com. on host sunabc: sunxyz# /usr/lib/nis/nisserver -R -d xyz.sun.com. -h sunabc ATTRIBUTES
