I have to run httpd on 3 ports of my centos installation.I chose port 80,8080 and 8081.I can access all three ports from the server machine,but not from the other machines in the network.When i tried nmap from the server terminal i got the following output.
PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
80/tcp open http
111/tcp open rpcbind
443/tcp open https
631/tcp open ipp
936/tcp open unknown
3306/tcp open mysql
8080/tcp open http-proxy
8081/tcp open blackice-icecap
I can access the port 80 application from the whole network.Whats blocking the ports 8080 and 8081?
