For yourself?
Get a list of all the boxes in a file, either IPs or hostnames.
The expect script would look something like:
Code:
#!/usr/local/bin/expect --  
spawn telnet [lindex $argv 0]
expect  ogin:
send loginName\r
expect ssword:
send yourPasswd\r
expect yourprompt
send "passwd  loginName\r"
expect  ssword:
send yourPasswd\r
expect ssword:
send newPasswd\r
expect ssword:
send newPasswd\r
expect yourPrompt
send exit\r 
expect  close
exit 0

The above example assumes that the passwd command is going to first ask you for your passwd, then you'll have to enter the new passwd twice.
Before you run it against all boxes, test it with one box. Make sure you log into the box first on another terminal, just in case.
Code:
myscript.exp  hostname

If no issues, remove the hostname from your sever list, then do
Code:
for x in $(cat boxList.txt); do
myscript.exp  $x
done

Quick note, if your prompt is $ or ends in $, you need to comment it out in the expect script., so expect sees it as a regular character. Otherwise it'll go very slow.

NAME
runtest - the DejaGnu test driver program SYNOPSIS
runtest [ options ] DESCRIPTION
DejaGnu is a framework for running test suites on GNU tools. It is written in expect, which uses TCL (Tool command language). runtest is the test driver program; use it to control what tests to run, and variations on how to run them. You can find a comprehensive description of DejaGnu and runtest in The DejaGnu Testing Framework or its Info version, dejagnu.info. OPTIONS
--all Print all test output to screen. By default, only unexpected results are displayed. --baud rate Set the baud rate for a serial line connection. Some serial interface programs (like tip) don't use this value but instead use a separate initialization file. --connect type The type of connection to use. The choices are rlogin, telnet, rsh, kermit, tip and mondfe. --debug Turn on expect internal debugging output. All output is logged to a file called dbg.out. The output of the --strace also goes into this file. --help Prints out a help screen and then exits. --host type The configuration string for the host. --ignore test1.exp test2.exp ... Do not run the specified tests. Electronic mail addresses to receive test results. --name hostname The network hostname of the target board. --objdir path path is a directory containing compiled test code. --outdir directory The name of a directory for test log output. --reboot Reboot the target board when runtest initializes (if supported). --srcdir path path is a directory containing test directories. --strace N Turns on expect internal tracing to N levels deep. --target type The configuration string for the target. --tool toolname Specify the tool to be tested. toolname controls the test suite applied, and the associated initialization module. --verbose, -v Turns on more debugging output from test cases and DejaGnu utility code. Use more than once to increase output further. --version, -V Prints out the versions of DejaGnu, expect and Tcl. -D[number] Activate the Tcl debugger.number can be either 1 or 0. If it is 1, then the expect shell will break when it starts to run. All ^C's drop DejaGnu back to the debugger prompt. A 0 starts DejaGnu like normal, but a ^C drops to the debugger prompt. Any file name on the command line is assumed to be a subset of the test names to run. Usually these are the names of the expect test driver, ie... special.exp. Makefile style variables are used to specify tool names and their flags; these and other configuration dependent values are saved in the file site.exp, created during configuration. EXIT CODES
runtest sets the exit code to 1 if any of the tests failed, or sets it to 0 if all the tests passed. SEE ALSO
The DejaGnu Testing Framework (dejagnu.info). This is the DejaGnu manual; its source is the SGML files doc/*.sgml. in the DejaGnu distri- bution. AUTHOR
