Thanks...few things to clear; we do need password to connect to remote hosts from this centralized server.....
I have changed things a bit; I have managed to ssh <sever1> and run the script located on the remote server (i.e. server1); but output of the script is needed to send back to the centralized server; the script is below that I am planing to run on each server.....
how can I send output of below script back to centralized server in a file; and i need that file mailed to me?
--Script to connect to remote servers from centeralized host
while read H; do ssh $H /ora/rman/scripts/bk1.sh 'BEGIN{printf "%s\n%s\n","'"$H"'","========"}NR>1{printf "%s\t%s\n",$1,$5}END{printf "\n"}';done < /export/h
ome/oracle/servers.lst > out.txt
File servers.lst contains
server1
server2
But I think its only working for server1
--The script will go to the archivelog directory and check for successful and failed archivelog backups (each server hosts many databases)
chkbck ()
{
for i in `ls /ora/rman/logs/`;
do
find /ora/rman/logs/$i/backup_a*.log -mtime -1 2>/dev/null
done
}
for i in `chkbck`;
do
print $i | cut -d"_" -f3
print $i
grep Exit $i
if egrep -i 'exit status 1' $i
then
print $i
fi
done

ntp.conf
ntp.conf(5) File Formats Manual ntp.conf(5)
Name
ntp.conf - Network Time Protocol configuration file
Description
The file is the configuration file for the Network Time Protocol (NTP) daemon, This file must be configured on your system before running
Any host names that you specify in the file must have an entry in the file, or an entry in the master database, if the database is being
served to your system by BIND/Hesiod or Yellow Pages.
The file has four entry formats:
trusting no
This entry guarantees that your system synchronizes only to the NTP servers identified in the peer and server entries specified. Dig-
ital recommends that all systems include the entry.
peer server
This entry identifies server as one of the NTP servers that your system trusts, and from which your system will accept time synchro-
nization. Your system may also provide time synchronization to this server. Servers can be identified by host name or internet
address.
NTP servers should be configured with entries.
server server
This entry identifies server as one of the NTP servers that your system trusts, and from which your system will accept time synchro-
nization. Your system can not provide time synchronization to this server. Servers can be identified by host name or internet
address.
NTP clients should be configured with entries.
peer /dev/null LOCL 1 -5 local
This entry identifies your system as a local reference clock. A local reference clock is the most accurate system clock available at
your site. If you receive time synchronization from the Internet NTP service, you should not include this entry on any of your sys-
tems. At most, one system in a set of nodes running should be identified as a local reference clock.
A host which specifies this entry should not specify any or entries.
Examples
This is a sample configuration file for an NTP client which receives time synchronization from the NTP servers: and Lines beginning with a
number sign (#) are comments.
#
# NTP Configuration File
# This file is mandatory for the ntpd daemon
#
#
#
# ** A L L **
#
# "trusting no" prevents this host from synchronizing
# to any host that is not listed below. It is recommended
# that all hosts include the line "trusting no".
#

#
# ** S E R V E R **
#
# If you are configuring a server, use "peer" entries to
# synchronize to other NTP servers. For example, server1,
# server2, and server3.
#
#peer server1
#peer server2
#peer server3
#
#
#
#
# ** C L I E N T **
#
# If you are configuring a client, use "server" entries to
# synchronize to NTP servers. For example, server1, server2,
# and server3.

# ** L O C A L R E F E R E N C E C L O C K **
#
# If you are configuring a local reference clock, include the
# following entry and the "trusting no" entry ONLY.
