Cheap iftop

Shows updated status in a terminal window for connections to port '80' in a human-friendly form. Use 'watch -n1' to update every second, and 'watch -d' to highlight changes between updates.

If you wish for status updates on a port other than '80', always remember to put a space afterwards so that ":80" will not match ":8080".

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
while sleep 1; do date; (netstat -a -n | grep 80) ; done

Know a better way?

If you can do better, submit your command here.

What others think

nice but won't tell me which vhost the connection went to or to which hosted site. any chance to see this info too?

watch -dn2 'netstat -anptu | egrep "^Proto|:80" | sort'

will watch on ports 80 and 8080 and sort output if u have a lot of connections, highliting changes with update interval 2 sec.

Ovidiu: When you say vhost, do you mean a protocol thing, like the domain part of the "RCPT TO:" lines of SMTP? In that case, you'll need packet inspection -- you're better off doing a 'tail -f logfile |grep ' instead.

ilrandir : I already mentioned using other values for "-n" in the comment.
