Enabling http access on port 80 for centos 6.3 from console
- by Hugo
Have a centos 6.3 box running on Parallels
and I'm trying to open port 80 to be accesible from outside
tried the gui solution from this post and it works, but I need to get it done from a script.
Tried to do this:
sudo /sbin/iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
sudo /sbin/iptables-save
sudo /sbin/service iptables restart
This creates exactly the same iptables entries as the GUI tool except it does not work:
$ telnet xx.xxx.xx.xx 80
Trying xx.xxx.xx.xx...
telnet: connect to address xx.xxx.xx.xx: Connection refused
telnet: Unable to connect to remote host
UPDATE:
$ netstat -ntlp
(No info could be read for "-p": geteuid()=500 but you should be root.)
