Watch Network Service Activity in Real-time


There is 1 alternative - vote for the best!

Terminal - Alternatives
lsof -i

I prefer to use this and not the -n variety, so I get DNS-resolved hostnames. Nice when I'm trying to figure out who's got that port open.

netstat -ntauple

Know a better way?

If you can do better, submit your command here.

What others think

try iptraf. lsof -i is a one time deal. real-time would imply that you could see network activity as it happens in a continuous manner. iptraf is a basic utility that lets you do just that.

watch "lsof -i"

Same thing using ip address instead of dns hostname

lsof -Pan -i tcp -i udp
