A quick way to check is something like

netstat -an | grep :80 | sort

or

netstat -an | grep EST

The fisrt will show all HTTP connections sorted by IP regardless of state. The second, all established connections regardless of port number.

Thanks for the info bhd

This will retunr a list correct/ Is there a way to get the server to count them?

Hi,

netstat -an | grep -c :80 might be good for counting them.

Also, if you use "iptraf", you can see current traffic by port number, network interface etc.

yum install iptraf if you have CentOS 4 (and maybe others too)
