Recent commentsUseful 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!! :-)
Cool
Very useful.
Definitely a great tool
my first tool to analyse my network traffic !
iftop: in a word.. COOL.
I'm using your software since some day, and I have to admit that's very useful. Thank you a lot for your time and energy, BiC.
