Use "netstat -ntlp" to show which processes are listening on a which
ports. lsof is inaccurate (as in this case -- only one of those httpd
processes is listening on port 80)

If there is a process is listening on a given tcp port but you can't 
telnet to it, it's almost invariably iptables blocking the traffic.
Do you have a rule to allow traffic on the lo interface? If not, it's
probably worth adding one for all but the most security paranoid setups.
