[Solved] Can't connect to the web page

[jbruyet]

Sorry for the long delay. I did a fresh install of CentOS 6.5, installed Nagios using the link listed in an earlier post, tried to access the web page and chrome gave me this (with and without /nagios):

Code: Select all

Oops! Google Chrome could not connect to 192.168.2.25

I have several httpd processes running:

Code: Select all

Selinux has been disabled:

Code: Select all

[root@FreeNag ~]# getenforce
Disabled
[root@FreeNag ~]#

and the only open port is 22:

Code: Select all

Nmap scan report for freenag.domain.com (192.168.2.25)

Host is up (0.0013s latency).

Not shown: 65534 filtered ports

PORT   STATE SERVICE

22/tcp open  ssh

MAC Address: 00:19:BB:33:AD:BA (Hewlett-Packard Company)

Is there a "common knowledge" step for getting port 80 open that I may be missing? I won't view ANY responses as condescension so please feel free to "post 'em if you got 'em."

Thanks,

From what I'm seeing everything should be working, this and previous diagnostic steps:

Code: Select all

[root@FreeNag ~]# netstat -l | grep http
tcp        0      0 *:http                      *:*                         LISTEN
[root@FreeNag ~]#

Hmmm...

Thanks,

Run:

Code: Select all

iptables -I INPUT -p tcp -m state --state NEW --dport 80 -j ACCEPT
service iptables save

Check iptables to make sure the rule was added:

Code: Select all

iptables -L -n

[jbruyet]

YES!!!!!! Thank you lmiltchev, that did the trick! I thought it had to be firewall-related but I didn't realize iptables was active by default. Now I can get on with my install.

Thanks again,
