Bash script to test IP range on server

Hello,
We have to configure servers with a range of IPs which is in itself a subject for another script assistance request -but- we have run into quite a few IP ranges with routing problems lately.

I've been trying to figure out the best way to test a range of IPs, I mean, manually it's not much fun typing "telnet ip 22" then "quit" a few dozen times for each setup. (I log into another linux box and try to telnet to SSH on each IP on the new server, this makes sure the IP is at least functioning and reachable).

I'm open to suggestions for a better method, of course.

A bash script I can upload to my work box and then just input a start and stop IP for the range w/ a result would be great.

Actually making a SSH connection on each IP and transferring a file or running MTR or some other diagnostic over each connection would probably be more "flash" in terms of something I can copy and paste into the customer's deployment report.

I'm just starting off with writing my own bash scripts and could really use the help on this.

Net::OpenSSH::Compat::Perl(3pm) 			User Contributed Perl Documentation			   Net::OpenSSH::Compat::Perl(3pm)

NAME
Net::OpenSSH::Compat::Perl - Net::OpenSSH adapter for Net::SSH::Perl API compatibility SYNOPSIS
use Net::OpenSSH::Compat::Perl qw(:supplant); use Net::SSH::Perl; my $ssh = Net::SSH::Perl->new('host'); $ssh->login($user, $passwd); my ($out, $err, $rc) = $ssh->cmd($cmd); DESCRIPTION
This module implements a subset of Net::SSH::Perl API on top of Net::OpenSSH. After the module is loaded as... use Net::OpenSSH::Compat::Perl qw(:supplant); ... it supplants the Net::SSH::Perl module as if it were installed on the machine using Net::OpenSSH under the hood to handle SSH operations. Setting defaults The hash %Net::OpenSSH::Compat::Perl::DEFAULTS can be used to set default values for Net::OpenSSH and other modules called under the hood and otherwise not accesible through the Net::SSH::Perl API. The entries currently supported are: connection => [ %opts ] Extra options passed to "Net::OpenSSH::new" constructor. Example: $Net::OpenSSH::Compat::SSH::Perl::DEFAULTS{connection} = [ ssh_path => "/opt/SSH/bin/ssh" ]; BUGS AND SUPPORT
This is a work in progress. "register_handler" method is not supported. Net::SSH::Perl submodules (i.e. Net::SSH::Perl::Channel) are not emulated. Anyway, if your Net::SSH::Perl script fails, fill a bug report at the CPAN RT bugtracker (https://rt.cpan.org/Ticket/Create.html?Queue=Net-OpenSSH-Compat <https://rt.cpan.org/Ticket/Create.html?Queue=Net-OpenSSH-Compat>) or just send me an e-mail with the details. Include at least: 1 - The full source of the script 2 - A description of what happens in your machine 3 - What you thing it should be happening 4 - What happens when you use the real Net::SSH::Perl 5 - The version and name of your operating system 6 - The version of the OpenSSH ssh client installed on your machine ("ssh -V") 7 - The Perl version ("perl -V") 8 - The versions of the Perl packages Net::OpenSSH, IO::Pty and this Net::OpenSSH::Compat. Git repository The source code repository is at https://github.com/salva/p5-Net-OpenSSH-Compat <https://github.com/salva/p5-Net-OpenSSH-Compat>. My wishlist If you like this module and you're feeling generous, take a look at my Amazon Wish List: <http://amzn.com/w/1WU1P6IR5QZ42> Also consider contributing to the OpenSSH project this module builds upon: <http://www.openssh.org/donations.html>.
