            Wish I found out about iftop earlier, such a useful tool!

            Nice tool. Wish it would display in my local charset (UTF-8) instead of gibberish, but otherwise great.

            Useful to me daily
            I'm very thankful for this code. I use it on a daily basis as one of my monitors.

            I have a couple of old monitors running splitvt beside me all day and one 'screen' is always running iftop. I even run it occassionaly on my own box when I've forgotten what my own network should be doing (say, a cron); I've caught more than a few ssh dict attacks that way.

            Simple yet awsome -- THANKS!! :-)
