I'm sure this is very noobish, so forgive me. I'm trying to run a node.js server on port 8080 of my ubuntu 10.04.
Here's the result of iptables -L on the server:
Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination
And here's the result of nmap -p 8080 (edited the ip address because everything is or should be wide open)
nmap 173.203.xxx.xxx -p 8080 -A Starting Nmap 5.00 ( http://nmap.org ) at 2011-05-19 22:52 PDT Interesting ports on xxx (173.203.xxx.xxx): PORT STATE SERVICE VERSION 8080/tcp closed http-proxy
Why on earth is 8080 seen as closed? Adding this did not help:
iptables -A OUTPUT -p tcp --dport 8080 -j ACCEPT iptables -A INPUT -p tcp --dport 8080 -j ACCEPT
I'm really confused.
I'll add this, in case it helps, but I don't know
netstat -pan | grep 80 tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN 16785/node tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 16471/apache2
I can access my regular website running off of port 80 on apache, but the node.js server is inaccessible from outside. Accessing it from the server itself works fine.
So my question is: how would I go about debugging this? Could there be something else than iptables blocking some ports? How do I find out what it is?
Any help much appreciated!
