command line network bandwidth tool?

[nosp <nosp xades com>]

Anyone recommend a command-line network bandwidth tool they use on
fedora?  I'm talking about something to show MB/sec across the local
machine's network interface(s), and perhaps more (breakdown by protocol,
etc.).  I can't find any pre-packaged ones in fedora (bad search
criteria?) but have seen ntop, ipband, and iptraf mentioned on the
web...

Thanks
