I have this requirement to change the password for other servers remotely from one server. So, I installed public keys on all servers and wrote the following script to do the job. Something appears to be wrong with my loop, as it only changes one server and ignores the rest. I'm testing the script with a test data file with about 5 servers in it. The data file is the command-line argument to the script. Can you please tell me what's wrong and how to fix it?
As always, I truly appreciate this community effort. You guys are truly awesome; thank you very much.
Code:
#!/bin/bash
##data file name is passed in as argument to .sh script
filename="$1"
while read -r line
do
##newPassword and username are placeholders
ssh $line 'echo -e "TestPW\nTestPW" | passwd SomeUser'
done < "$filename"

setup-ds.pl
SETUP-DS.PL(8) System Manager's Manual SETUP-DS.PL(8)NAME
setup-ds.pl - Set up an instance of Directory Server
SYNOPSIS
setup-ds.pl [--options] -- [args]
DESCRIPTION
Set up a Directory Server instance. Creates the configuration files for an instance of Directory Server based on a few parameters like the
hostname, port number, and directory manager information. Can be run in interactive mode with different levels of verbosity, or in silent
mode with parameters supplied in a .inf format file or on the command line.
OPTIONS
A summary of options is included below:
--help This message
--version
Print the version and exit
--debug
Turn on debugging
--silent
Use silent setup - no user input
--file=name
Use the file 'name' in .inf format to supply the default answers
--keepcache
Do not delete the temporary .inf file generated by this program
--logfile
Log setup messages to this file - otherwise, a temp file will be used
--update
Update existing installations - add/update schema files, add/change configuration, add new instance scripts, etc. You must run set-
up-ds.pl -u after upgrading your packages. You will usually have to restart your servers in order for all of the changes to take
effect (e.g. adding/changing plug-in configuration), so schedule this when you can afford a little downtime.
--continue
(Update only) Keep going even if errors occur. You will usually not need to use this option unless your installation is broken and
you need to force it to update in order to fix it.
For all options, you can also use the short name e.g. -h, -d, etc. For the -d argument, specifying it more than once will increase the
debug level e.g. -ddddd
args: You can supply default .inf data in this format:
section.param=value
e.g.
General.FullMachineName=foo.example.com
or
"slapd.Suffix=dc=example, dc=com"
Values passed in this manner will override values in an .inf file given with the -f argument.
UPDATES
The update process (setup-ds.pl -u) can work in one of two modes:
Online: Configuration changes are made to the running directory servers using LDAP. The operations must be performed as an administrative
user. You must provide the name and password, for each instance if there is more than one instance of directory server. Some changes (e.g.
plug-ins) may require a directory server restart to take effect. The update script will notify you if a restart is required.
Offline: The changes are made to the server configuration files. The servers MUST FIRST BE SHUTDOWN BY YOU. The script will not shutdown
the servers for you. You MUST shutdown the servers in order to use this mode. A username and password are not required to use Offline
mode. If the servers are not shutdown, CHANGES WILL BE LOST.
To summarize:
Online - servers remain running - you must provide admin name and password for each server - servers may need to be restarted
Offline - servers must be shutdown - no username or password required
