Hey I was just curious if anyone knew of any scripts or command line programs that are out there that could be used to check bandwidth on a network.

iptraf can do this for you, i believe; get it from yum.

Here's a PHP script that I use to give me long-term, month-to-month stats on total bandwidth usage, run from cron every 5 minutes:
#! /usr/bin/php -q <?
if (!$in=`/sbin/ifconfig -a eth0`) die ('Error: no input from ifconfig -a call'); $now=mktime(); # RX bytes:1294815560 (1234.8 Mb) TX bytes:3493560535 $match="/RX bytes:([0-9]+).*?TX bytes:([0-9]+)/"; if (!preg_match($match, $in, $r)) die ('Error - no matching for input from eth1'); if (!$fp=fopen("/var/log/traffic.log", 'a')) die ('Error - unable to open /var/log/traffic.log'); fwrite($fp, "$now RX: ".$r[1]." TX: ".$r[2]."\n"); fclose($fp);
?>
If you want some cheezy scripts to parse the resulting data file, I can help you there too. =)

If you run iptables, you could install ipac-ng.
If you're looking for something that will eat all availalbe bandwidth and report what it found, iperf is the ticket.
Also see ndt: http://e2epi.internet2.edu/ndt/
which isn't exactly the same thing (although iperf is part of the backend) but is similar and cool.

yum install iptraf
