write net command or using Ciscoworks if you have one implemented within your organisation to do your config backup periodically is the best solution to this. It is BAD PRACTICES not to backup your system config and writting down parameters. You should adopt BEST PRACTICES in all you do.

Here is my script. It first reads all my PIX IP's from a file then uses those as input to run through the script for each one. If you don't know Perl (or any other language) this might not make sense. I use a second script to tar up all of my IOS and PIX configs where they are then transferred to yet another server for long term tape backup.

#!/usr/bin/perl -w

#Written by SRUE

#this script backs up all cisco pix devices via tftp

use Net::Telnet::Cisco;

$passwd = 'password';

$enable_passwd = 'password';

open (HOSTS, "/usr/local/apache2/htdocs/db/pixhosts.db");

@hosts = ;

chomp (@hosts);

foreach $pix (@hosts)

{

my $session = Net::Telnet::Cisco->new(Host => $pix, Timeout => 30);

$session->prompt('/[\$%#>] $/');

$session->login('username', $passwd);

$session->enable($enable_passwd);

$session->cmd("write mem\nwrite net\n");

}

close (HOSTS);

------------------

there's more to it than all this. I also wrote a web page where I can add/delete new IOS or PIX devices. i use perl/cgi to add those entries to their respective files where Perl reads them and backs them all up.

(btw, I really don't know much Perl, just the bare minimum imo.)
