I want to install webserver-apache on a Linux platform which uses port no.80 but I am not sure whether is port is open or not, and is being used by some other application or not.

  1. Output of grep 80 /etc/services is:
http  80/tcp  www www-http   #World Wide web Http
http  80/udp  www www-http   #Hypertext transfer protocol
  1. netstat -an | grep 80 | more:

It gives some IP's one of which is

IP:80 TIME_WAIT

Could you please help and tell how can i find out if port 80 is open and unused so that I can start installation.
