Hi,

you can achieve this making a trust between servers, and then running a script.

Also if you have Secure Shell installed, you can very easily establish a trust between the servers and then run a script.

For EG:

for HOST in hp1 hp2 hp3
do
echo #HOST
ssh $HOST w;..;..
done

minor correction

for HOST in hp1 hp2 hp3
do
echo $HOST
ssh $HOST w;..;..
done

I have used 2 methods to accomplish what you want uucp\uux is one Kermit is another. Kermit does come with hpux, Shown is a contribed example. I did not test it but it is from working code. you would need to flush out error checking and the command you want to really do

#!/bin/sh
#
#

dojob()
{
TOHOST=`echo $1`
WAIT_THIS_LONG="${2}" #added to allow for wait of long commands
WAIT_THIS_LONG=${WAIT_THIS_LONG:-10} #default if not set
echo "
set network TCP/IP
#set host 10.254.7.34
set host ${TOHOST}
input 10 login:
if failure exit 1 No login prompt
output USERID\13
input 10 word:
if failure exit 1 No password prompt
output PASSWD\13
input 10 $
ls -ld \13
input ${WAIT_THIS_LONG} $
output exit\13
output quit
"
}


for HOST in 10.254.0.1 10.254.0.2 10.254.0.3 10.254.0.4
do
trap "" 1 2 3
#passwords and USERID can be set as variables past to kermit
#like host and timeout
dojob ${HOST} 4600 |/usr/bin/kermit
trap 1 2 3
done

Hi Wish,
my sugegstoin id to prepare a script which collects all the required data and run it on all the server by remsh:

for server in one two three four
do
remsh $server -l $user -n "script"
done

to do this you have to add an entry in the target .rhost

or in alternative you can use rexec instead of rmsh. In this case you have to create a file .netrc on the source server with the logon info for the target server.
For furhet info man rexec, remsh can help.


HTH,
Art
