Access to Apache web server from network client

fedix · 03-08-2016, 08:59 AM

Why can't I access my web server from another machine on the local network.

I've changed the httpd.conf to allow access from the network to port 80; but still no access. Interestingly though, I can access the webserver:631 (cups) as well as any other port (for example an alfresco install on port 8080), but not the default port 80.

Thanks!

Perhaps a firewall problem. Run

Code:

iptables -nvL|grep 80

to see if post 80 is open on your firewall

You can also run

Code:

netstat -tanpl|grep 80

to verify that apache is listening on its public IP too.

router settings?

OK, thanks. It seems as if my iptables does not allow port 80. But according to firewall-config on the "services" tab, it looks like port 80 is indeed open?

How can I open port 80?

Thanks!

It depends on your distro.
So use your favorite search engine and look for it

My distro is Fedora 23. I've been searching and made all kinds of changes through firewall-config, command line etc. Still no access.

This is the output of iptables -nvL|grep 80

Help please.

Hi,

Looks like the port 80/tcp is open already. Perhaps you need to delete the 2 occurrence of the iptalbes rule (and the 80/udp)
I don't use Fedora, so better read the official documentation of firewalld
For quick instructions check this

Code:

firewall-cmd --add-service http

Add the --permanent option to persist over restarts.
Once the port is open in firewalld, you do need something listening on port 80, usually the httpd server.

And maybe you need to expound on the "I can't access" problem. Maybe the "webserver" listening on port 80 is not booted up? Or maybe it's up and firewalld allows connection but SELinux doesn't allow it?

Code:

semanage port -l | grep http_port_t
